ABSTRACT

THE IMPACT OF COMPUTER AIDED DRAFTING TECHNOLOGY ON INDUSTRIAL EDUCATION

CURRICULUM IN BRITISH COLUMBIA SECONDARY SCHOOLS

SAVAGE, JOHN HOWARD, M.A.

UNIVERSITY OF BRITISH COLUMBIA, 1985

STATEMENT OF THE PROBLEM

The purpose of t h i s study was to i d e n t i f y the pr e r e q u i s i t e s k i l l s most

appropriate to t r a i n i n g and/or employment i n computer aided drafting...

S p e c i f i c objectives of the study were concerned with:

1. The prevalence of CAD i n s p e c i f i c i n d u s t r i e s .

2. The r e l a t i o n s h i p between the s i z e and/or type of CAD system and the

t r a i n i n g required to operate i t .

3. The background and t r a i n i n g of i n d i v i d u a l s operating CAD systems.

A. The preferences of employers as to the education of t h e i r CAD operators.

5. The preferences of CAD t r a i n i n g i n s t i t u t i o n s as to the education of

CAD t r a i n i n g candidates.

6. The methods by which i n d i v i d u a l s i n industry received CAD t r a i n i n g .

7. The methods of CAD t r a i n i n g preferred by employers.

8. The importance of c e r t a i n s k i l l s r e l a t i v e to CAD employment or

t r a i n i n g .

9. The importance of c e r t a i n secondary school d r a f t i n g curriculum items

r e l a t i v e to CAD t r a i n i n g or employment.

10. The i d e n t i f i c a t i o n of secondary school curriculum areas to be

modified to s u i t the needs of industry and CAD t r a i n i n g i n s t i t u t i o n s .

PROCEDURES

The survey questionnaire method was used to obtain data f o r t h i s study.

Two p a r a l l e l , closed-form questionnaires were developed from a review of

relat e d l i t e r a t u r e and an analysis of current d r a f t i n g standards and techniques.

One questionnaire was sent to a l l t r a i n i n g i n s t i t u t i o n s i n B r i t i s h Columbia

o f f e r i n g courses i n CAD. The other questionnaire was sent to s i x t y - f i v e

businesses i n B r i t i s h Columbia i d e n t i f i e d as users of CAD technology.

The responses were analysed to provide information on the impact of

CAD technology on secondary school curriculum. The importance of p a r t i c u l a r

items was determined through c a l c u l a t i o n of mean p r i o r i t y or ranking l e v e l s .

FINDINGS'

The businesses surveyed were p r i m a r i l y involved i n mechanical and

el e c t r o n i c s d r a f t i n g followed by s t r u c t u r a l , a r c h i t e c t u r a l , and cartographic.

Training i n s t i t u t i o n s were concerned with a r c h i t e c t u r a l and c i v i l d r a f t i n g

followed by mechanical and s t r u c t u r a l . Data indicated that CAD was being

used i n a l l areas of d r a f t i n g .

CAD system descriptions indicated that a large number of businesses and

tr a i n i n g i n s t i t u t i o n s were using personal computer based CAD systems that

were les s expensive and easier to operate than larger mainframe or dedicated

systems.

Educational i n s t i t u t i o n s indicated that the majority of t h e i r CAD

tr a i n i n g candidates were upgrading themselves and that they preferred

candidates with a good d r a f t i n g background. Businesses indicated that most

of t h e i r CAD operators were draftspersons retrained f o r CAD. Few CAD

operators had received formal CAD t r a i n i n g although employers indicated a

h i r i n g preference f o r draftspersons with formal t r a i n i n g i n CAD.

Page 5: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

( :iy )

Both businesses and t r a i n i n g i n s t i t u t i o n s involved with CAD considered

manual d r a f t i n g s k i l l s and good problem solving a b i l i t y to be the most

important pre r e q u i s i t e s for CAD t r a i n i n g or employment. With respect to

s p e c i f i c d r a f t i n g s k i l l s , there was concensus on the importance of i n d i v i d u a l

items. Dimensioning to CSA standards was considered most important followed

by the three dimensional representations t y p i f i e d i n sketching, p i c t o r i a l ,

drawing, a u x i l i a r y views, and developments.

Both surveys indicated that c u r r i c u l a r change to r e f l e c t the changing

technology was necessary and should include the introduction •£>£ computer

aided d r a f t i n g at the secondary l e v e l as well as more d r a f t i n g course time

and more emphasis on computational and communication s k i l l s .

CONCLUSIONS

1. Drafting, e s p e c i a l l y computer aided d r a f t i n g , should be approached

as a necessary s k i l l f o r a wide v a r i e t y of occupations and not as

a vocation i n i t s e l f . This would require a conscious e f f o r t to open

secondary school d r a f t i n g programs to a l l students, not j u s t those

i n i n d u s t r i a l programs.

2. Drafting educators should acquaint themselves with the changing

technology of d r a f t i n g including contact with post secondary t r a i n i n g

i n s t i t u t i o n s and representative industry.

3. Secondary school d r a f t i n g programs should introduce students to

computer aided d r a f t i n g .

4. More emphasis should be placed on dimensioning to CSA standards and

on areas of d r a f t i n g that involve viewing an object i n three dimensions.

5. Secondary school curriculum should be modified to include more dr a f t i n g

time and place more emphasis on computational and communication s k i l l s .

CHAPTER ONE

INTRODUCTION

Background to the Problem:

Since the early 1970's, governments of many i n d u s t r i a l i z e d nations,

recognizing the benefits of computer aided design and manufacturing to

t h e i r economies, have promoted i t s adoption by both state and p r i v a t e

enterprise. The automated factory, made possible by advances i n microchip

technology, has become more a v a i l a b l e at in c r e a s i n g l y l e s s cost to a greater

number and wider v a r i e t y of businesses. M i l l i o n s of d o l l a r s have been spent

i n Europe, the United Kingdom, Japan, and the United States to encourage the

development and adoption of t h i s technology by industry, creating a coincident

increase i n the demand f o r t e c h n i c a l expertise. The development of required

t r a i n i n g and education f o r t h i s technology has been l e f t to the CAD/CAM

vendors, u n i v e r s i t i e s , t e c h n i c a l i n s t i t u t e s , and trade schools with l i t t l e

or no assistance from government. As a r e s u l t , education and t r a i n i n g f o r

CAD/CAM have become a p r i o r i t y i n these countries.

The Canadian government, recognizing the need f or expertise i n these

areas, has encouraged p r o v i n c i a l educational i n s t i t u t i o n s to develop

appropriate t r a i n i n g programs through i t s S k i l l s Growth Fund and other

programs. In B r i t i s h Columbia, there are sixteen i n s t i t u t i o n s presently

o f f e r i n g a v a r i e t y of high technology oriented courses. Most of these

i n s t i t u t i o n s have been a s s i s t e d through fe d e r a l and p r o v i n c i a l grants to

develop courses i n computer aided design, d r a f t i n g , and manufacturing

through the purchase and i n s t a l l a t i o n of CAD systems.

The most popular high technology programs, and the ones that promise

the most opportunity for employment i n B r i t i s h Columbia, are those that

o f f e r computer aided d r a f t i n g . In most cases, t h i s t r a i n i n g i s offered

as a part of a d r a f t i n g technology, engineering, or s i m i l a r program,

although there i s considerable demand for o f f e r i n g s of computer aided

d r a f t i n g as an upgrade course for engineers, a r c h i t e c t s , designers,

draftsmen, and other p r o f e s s i o n a l s .

There appears to be l i t t l e d i s t i n c t i o n between computer aided design

and computer aided d r a f t i n g and i t should be noted that most i n s t i t u t i o n s

are o f f e r i n g computer aided d r a f t i n g along with t h e i r regular courses i n

design. As the e x i s t i n g technology becomes more integrated, more systems

w i l l become a v a i l a b l e that incorporate the design parameters and manufactur­

ing c o n t r o l with the d r a f t i n g software. For the purpose of t h i s study,

design was considered to be concerned with engineering analysis rather

than the act of conceptualizing.

At the secondary school l e v e l , educators experience what can be

described as a "trickle-down e f f e c t " with regard to high technology

innovation and s i m i l a r advances. The computer education a v a i l a b l e at the

u n i v e r s i t y l e v e l i n the early 1960's has, i n twenty years, t r i c k l e d down

to the secondary school l e v e l . Word processing, which was once a v a i l a b l e

only at colleges and trade schools, i s now being taught at the grade seven

l e v e l i n some B r i t i s h Columbia school d i s t r i c t s . The same analogy may

apply to the computer aided d r a f t i n g technology. If t h i s technology i s to

t r i c k l e down in t o the secondary schools, as i t appears to be doing, a

r e v i s i o n of present d r a f t i n g curriculum becomes increasingly important.

Even without adopting t h i s technology at the secondary l e v e l , s k i l l s

presently being taught should be examined as to t h e i r s u i t a b i l i t y f o r

the technology of the workplace or further t r a i n i n g . Manual d r a f t i n g ,

as a vocation, i s r a p i d l y disappearing, but the need for appropriate

d r a f t i n g s k i l l s may be more important now, for an increasing number of

occupations, than ever before.

This study w i l l examine two s,tagescof influence on curriculum. The

f i r s t area i s that of recognition of changes i n technology and incorp­

orating them into the curriculum. As Hildebrand (1974) states,

"... i f i n d u s t r i a l a r t s d r a f t i n g programs are to remain e f f e c t i v e and current, i t i s e s s e n t i a l that the I n d u s t r i a l Arts educator s c r u t i n i z e and incorporate new p r a c t i s e s and innovations of industry into the d r a f t i n g programs." (p. 1)

The second stage:is i n t r o s p e c t i v e : to examine the present curriculum to

determine which areas are most important with respect to the requirements

of industry and post secondary education. Hildebrand also supports t h i s ,

asking,

"What have these changes meant for the d r a f t i n g educator? They have indicated a need for c a r e f u l analysis of course content i n an attempt to s e l e c t those elements most relevant i n l i g h t of current i n d u s t r i a l needs." (p. 4)

Further support i s offered by Case (1971),

"... i t i s necessary f o r i n d u s t r i a l educators to keep abreast of the rapid advancements i n the f i e l d of technology. Not only must they be cognizant of the changes taking place i n industry, they must also f i n d means of implementing these technological changes to update the c u r r i c u l a . " (p. 1)

Purpose of the Study:

The purpose of t h i s study i s to i d e n t i f y , through a survey of

in d u s t r i e s and educational i n s t i t u t i o n s , the p r e r e q u i s i t e s k i l l s most

appropriate to t r a i n i n g and/or employment i n computer aided d r a f t i n g .

S p e c i f i c objectives of the study are:

1. To determine the prevalence of CAD i n s p e c i f i c i n d u s t r i e s .

2 . To determine i f any r e l a t i o n s h i p e x i s t s between the s i z e and/or

type of CAD system and the t r a i n i n g required to operate i t .

3. To examine the background and t r a i n i n g of those i n d i v i d u a l s

presently operating CAD systems.

4. To determine i f employers have any preferences as to the

educational background of future CAD operators.

5. To determine i f CAD t r a i n i n g i n s t i t u t i o n s have any preferences

as to the educational background of the i n d i v i d u a l s they teach.

6. To determine the predominant methods by which i n d i v i d u a l s i n

industry received t h e i r CAD t r a i n i n g .

7. To determine which method of CAD t r a i n i n g i s preferred by

employers.

8. To determine the importance of c e r t a i n psychomotor, cognitive,

and i n d u s t r i a l s k i l l s r e l a t i v e to CAD employment or t r a i n i n g .

9. To determine the importance of present secondary school d r a f t i n g

curriculum items r e l a t i v e to CAD employment or t r a i n i n g .

10. To i d e n t i f y areas of secondary school curriculum requiring

m odification to s u i t the perceived needs of industry and CAD

t r a i n i n g i n s t i t u t i o n s .

S i g n i f i c a n c e of the Study:

Post secondary t r a i n i n g i n s t i t u t i o n s and representative i n d u s t r i e s

were asked for information concerning the operation of t h e i r CAD systems

and the r e l a t i v e importance of c e r t a i n s k i l l s and curriculum items to

further t r a i n i n g or employment i n computer aided d r a f t i n g . The findings

w i l l enable an informed r e v i s i o n of present curriculum i n d r a f t i n g and a

v a r i e t y of re l a t e d subjects. It w i l l also allow educators to better inform

students about s p e c i f i c requirements f o r CAD r e l a t e d occupations and w i l l help

to strengthen the r e l a t i o n s h i p between industry and educational i n s t i t u t i o n s

i n B r i t i s h Columbia.

Assumptions:

The r e s u l t s of t h i s study are based on the assumption that c e r t a i n factors

would not have a s i g n i f i c a n t e f f e c t on the v a l i d i t y of the information gathered.

S p e c i f i c a l l y , these assumptions are:

1. That the i n d u s t r i e s sampled were representative of those i n d u s t r i e s

i n B r i t i s h Columbia that employ CAD personnel.

2. That the educational i n s t i t u t i o n s sampled were representative of

those B r i t i s h Columbia i n s t i t u t i o n s o f f e r i n g t r a i n i n g i n CAD.

3. That the survey p a r t i c i p a n t s were honest, competent, and informed

i n t h e i r responses.

4. That the survey instruments did c o l l e c t the information for which

they were intended.

5. That the researcher would be unbiased and accurate i n M s reporting.

The study also assumed the following conditions:

1. That the information gathered would be of assistance i n r e v i s i n g

curriculum i n B r i t i s h Columbia secondary schools.

2. That CAD technology i s a s i g n i f i c a n t factor i n determining curriculum.

3. That curriculum change i n t h i s context would be b e n e f i c i a l to students,

education, and industry.

4. That informed opinion would be a useful measure or i n d i c a t o r of the

p r e r e q u i s i t e s k i l l s f o r CAD.

CHAPTER TWO

REVIEW OF RELATED LITERATURE

The review of the l i t e r a t u r e i s divided into three areas. The f i r s t

of these i s concerned with curriculum development and the r e l a t i o n s h i p

between industry and education. The second area i s concerned with recent

research and research methods i n i n d u s t r i a l education, p a r t i c u l a r l y i n

the f i e l d s of d r a f t i n g , computer graphics, and r e l a t e d t o p i c s . The t h i r d

area concentrates on t e c h n i c a l l i t e r a t u r e , journals, and p e r i o d i c a l s having

to do with computer aided d r a f t i n g and s i m i l a r technological innovations,

e s p e c i a l l y i n r e l a t i o n to education.

Curriculum Development:

Every curriculum researcher seems to have a d i f f e r e n t concept or

d e f i n i t i o n of curriculum to the extent that Eisner (1975) suggests that

consistency i n curriculum development theory would be a major accomplish­

ment. For the purposes of t h i s study, a number of current theories and

influences were reviewed with the i n t e n t i o n of providing a workable

t h e o r e t i c a l and p r a c t i c a l framework for c u r r i c u l a r r e v i s i o n i n I n d u s t r i a l

Education.

Stenhouse (1975) o f f e r s three current d e f i n i t i o n s f o r curriculum,

"Curriculum i s ' a l l the planned experiences provided by the school to a s s i s t the pupils i n a t t a i n i n g the designated learning outcomes to the best of t h e i r a b i l i t i e s . " 1 (Neagley and Evans 1967, 2);

"Curriculum i s the planned composite e f f o r t of any school to guide p u p i l learning toward predetermined learning outcomes." (Inlow 1966, 7);

"In view of the shortcomings of the currently popular d e f i n i t i o n , i t i s here s t i p u l a t e d that curriculum i s a structured ser i e s of

Page 20: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

intended learning outcomes. Curriculum prescribes (or at l e a s t a n t i c i p a t e s ) the r e s u l t s of i n s t r u c t i o n . " (Johnson 1967, 130).

He then o f f e r s h i s own tentative d e f i n i t i o n of curriculum,

"A curriculum i s an attempt to communicate the e s s e n t i a l p r i n c i p l e s and features of an educational proposal i n such a form that i t i s open to c r i t i c a l scrutiny and capable of e f f e c t i v e t r a n s l a t i o n into p r a c t i s e . " (p. 4)

Expanding on t h i s , he adds,

"A curriculum i s the means by which the experience of attempting to put an educational proposal into p r a c t i s e i s made p u b l i c l y a v a i l a b l e . It involves both content and method, and i n i t s widest a p p l i c a t i o n takes account of the problem of implementation i n the i n s t i t u t i o n s of the educational system." (p. 5)

H i c k l i n g (1979) focuses on those who define curriculum as a plan,

"For a d e s c r i p t i o n of what curriculum i s , we turn to Young (1977), who defines curriculum as "... a plan o u t l i n i n g the objectives and content of a subject which i s a v a i l a b l e to learners i n school." (p. 8) Resnick (1975) states that "... a curriculum can be thought of as a ser i e s of a c t i v i t i e s e x p l i c i t l y designed to change the knowledge and competence of those who engage i n i t . " (p. 36) And Heasley 1974) views curriculum as "... a plan of experiences designed by and for educators to nurture various aspects of the t o t a l development of c h i l d r e n . " (p. 44)

A l l of these d e f i n i t i o n s are somewhat c i r c u l a r , s i m i l a r to the o l d

adage that curriculum i s "what i s taught". This w r i t e r f e e l s that a d e f i n i t i o n

of curriculum should also i n d i c a t e that curriculum i s always influenced by

an external culture to the benefit of that culture. Bowles and G i n t i s (1976)

suggest that such a r e l a t i o n s h i p e x i s t s i n western society.

"We have been able to show more than a correspondence between the s o c i a l r e l a t i o n s of production and the s o c i a l r e l a t i o n s of education at a p a r t i c u l a r moment. We have shown that changes i n the structure of education are associated h i s t o r i c a l l y with changes i n the s o c i a l organization of production. The f a c t that changes i n the structure of production have p a r a l l e l changes i n schooling establishes a strong prima f a c i e case for the causal importance of economic structure as a major determinant of educational s t r u c t u r e . " (p. 224)

I t i s t h i s external influence that develops or changes curriculum.

Page 21: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

Curriculum w i l l continuously evolve to r e f l e c t the culture of the society

that i t serves. Ralph Tyler (1978) also alludes to t h i s , s t a t i n g ,

"As society demands more of our schools we must be more inventive i n devising f e a s i b l e programs — based, as Rubin in d i c a t e s , on r a t i o n a l p o l i c i e s — that w i l l meet the new conditions."

"... attack serious educational problems throughtfully [ s i c ] , system­a t i c a l l y , and p e r s i s t e n t l y , using more e f f e c t i v e l y the a v a i l a b l e resources. This i s an evolutionary process l i k e those i n the past that have made our schools responsive to continuing s o c i a l change." (p. 186-7)

As our society becomes more technological, there i s a tendency f o r

curriculum to become more humanistic i n response to the associated socio--

l o g i c a l problems, but the demand for relevance i n education i n t e n s i f i e s .

Peterson and Park (1975) sense the possible los s of humanistic values depending

on how education reacts to t h i s pressure.

"Career education, the most expansive human resources development program the government has ever proposed, could, depending on the value systems which i t espouses, be the near f i n a l step i n subordinating the education system to the production system. It i s possible that h i s t o r i a n s of the future w i l l look upon our time as another Dark Age, t h i s time blanketed by industry rather than the church.

There are, however, a l t e r n a t i v e s . I t i s almost i n e v i t a b l e that, as systems grow, t h e i r boundaries begin to overlap and they merge into supersystems. This i s not n e c e s s a r i l y bad. The growing interchange between education and the other sectors of society i s p o t e n t i a l l y b e n e f i c i a l . The question i s , can education enter into c o l l a b o r a t i v e e f f o r t s — yet preserve humanistic values and goals?" (P. 283)

The s h i f t away from c l a s s i c a l education i n Western c i v i l i z a t i o n probably

began i n the 17th Centure but the i n c l u s i o n of i n d u s t r i a l c u r r i c u l a only

began i n the mid-1800's. I t i s i n t e r e s t i n g to note that the l a s t major

change of great s i g n i f i c a n c e at the secondary l e v e l was the addition of

vocational education at t h i s time. This was i n d i r e c t response to increasing

i n d u s t r i a l i z a t i o n and the need for a competent workforce. Wirth (1966)

explaing the s i t u a t i o n at the turn of the century,

Page 22: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 13 -

1... new courses of a technical nature were demanded as the i n c r e a s i n g l y complex technology and larger bureaucratic i n s t i t u t i o n s required new l e v e l s of s k i l l that could not be acquired i n c i d e n t a l l y on the job." (p. 204)

John Dewey (1938) explains the lack of relevancy of t r a d i t i o n a l education,

s t a t i n g ,

"The notion that some subjects and methods and that acquaintance with c e r t a i n f a c t s and truths possess educational value i n and of themselves i s the reason why t r a d i t i o n a l education reduced the material of education so l a r g e l y to a d i e t of predigested materials." (p. 46)

Dewey looked upon t r a d i t i o n a l education as being ' c u l t u r a l ' and he thought

that vocational education, i f approached i n a humanistic, l i b e r a l way,

could engender a much broader understanding of that culture. Wirth (1966)

explains,

"Dewey used the term semivocational to ind i c a t e that no pretensions would be made to turn out expert technicians. The high school should present studies that would permit the exploration of i n t e r e s t s and capacities to youth who approached i t as merely an avenue to work. A range of vocational experiences should be.provided. In addition, every student, regardless of h i s job o r i e n t a t i o n , should be well grounded i n non-vocational subject matter. An i n t e l l e c t u a l adjustment to the p o l i t i c a l , economic, r e l i g i o u s , c u l t u r a l , and s o c i a l aspects of l i f e also had to be made. The s p e c i a l i z a t i o n and complexity of modern industry made i t ever more d i f f i c u l t f o r men to see t h e i r work i n terms of the s o c i a l whole. The goal he projected was an education that would equip students to emerge from the schools with a broad understanding of the nature of industry and technology, a respect for the d i g n i t y of work, and an awareness of the s o c i a l implications of change. They would have some in s i g h t s into the nature of the economic system, and of the rol e s of management and labour unions." (p. 230)

Today, the external culture that so profoundly a f f e c t s our educational goals

i s changing at an ever increasing rate such that educators are faced with

preparing students for occupations that may not even e x i s t yet. To

accomplish t h i s they must stay abreast of changes i n t h e i r subject matter,

keeping the curriculum relevant and providing as broad an information base

as possible for t h e i r students. Trump and M i l l e r (1977) i n a paper on the

Page 23: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 14 -

future of I n d u s t r i a l Arts claim that,

"... the dominant objective of I n d u s t r i a l Arts should be that of providing an understanding of American industry and an awareness of i t s changing technology. Programs using t h i s as the basic objective are i d e n t i f i e d with a technology approach. In i t s simplest form t h i s approach redefines the old approach of 'a degree of s k i l l ' as an understanding of the necessity for s k i l l f u l use of tools rather than s k i l l i n the use of t o o l s . " (p. 84)

These views are not new i n the f i e l d of curriculum development. Bruner

(1960) i n The Process of Education proposes that,

"... the curriculum of a subject should be determined by the most fundamental understanding that can be achieved of the underlying p r i n c i p l e s that give structure to the subject. Teaching s p e c i f i c topics or s k i l l s without making clear t h e i r context i n the broader fundamental structure of a f i e l d of knowledge i s uneconomical i n several deep senses." (p. 30)

Perhaps Bruner i s r e i t e r a t i n g some of Whitehead's Aims of Education (1929),

"The r e s u l t of teaching small parts of a large number of subjects i s the passive reception of disconnected ideas, not illumined with any spark of v i t a l i t y . ' Let the main ideas which are introduced into a c h i l d ' s education be few and important, and be thrown into every combination p o s s i b l e . " (p. 2)

One of the probelms of implementation r e l a t i v e to t echnologically

imposed c u r r i c u l a r change (appropriate to I n d u s t r i a l Education) i s discussed

by Stenhouse (1975).

" I t seems to be f a i r and h e l p f u l to describe as reference groups those groups outside the school which create and curate knowledge and s k i l l s and values. Reference i s indeed made to them as sources of standards..." "... there i s an implication that i n the pressure of school s i t u a t i o n s teachers may develop within the educational process cultures which, to a greater or l e s s e r degree, lose touch with the reference group cultures they are meant to represent to the p u p i l s . " (p. 13)

These comments may be e s p e c i a l l y applicable to the secondary school

s i t u a t i o n which can be so r e s i s t a n t to change. There i s very l i t t l e

i ncentive for teachers, e s p e c i a l l y I n d u s t r i a l Education teachers, to update

t h e i r programs or t h e i r teaching methods and yet i t i s so important for

Page 24: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

them to do so. Even at the turn of the century, Carlton (1908) stated,

"Both industry and the students are injured by the i s o l a t i o n of the high school, the college, and the u n i v e r s i t y from the p r a c t i c a l a f f a i r s of the i n d u s t r i a l and commercial world." (p. 92)

He even went so f a r as to suggest that,

" A l l teachers should work a portion of the time, i n order that they may come into actual contact with the i n d u s t r i a l and economic l i f e and problems of today." (p. 92)

Dewey (1938) also maintained that educators should have f i r s t - h a n d

experience or knowledge of t h e i r subject areas.

"... education i n order to accomplish i t s ends for both the i n d i v i d u a l learner and for society must be based on experience — which i s always the actual l i f e experience of some i n d i v i d u a l . " (p. 89)

Trump and M i l l e r (1977) q u a l i f y t h e i r view on the necessity of upgrading

I n d u s t r i a l Education teacher q u a l i f i c a t i o n s , s t a t i n g ,

" I f the proposals for an I n d u s t r i a l Arts curriculum based on technology are incorporated into the comprehensive secondary school program, I n d u s t r i a l Arts w i l l undoubtedly take on a new image. I t s p o s i t i o n i n general education w i l l be s o l i d i f i e d and i t s i n t e g r a t i o n with other subject-matter areas w i l l be axiomatic. I t w i l l necessitate r e t r a i n i n g of teachers and the opening of the I n d u s t r i a l Arts c u r r i ­culum to the e n t i r e school." (p. 85)

Burns and Brooks (1970), concerned about the time lag involved with the

introduction of new material i n education, also point to the need f o r i n -

service r e t r a i n i n g ,

"Perhaps a l l of t h i s demands new approaches to teacher t r a i n i n g and c e r t a i n l y some system of i n - s e r v i c e r e t r a i n i n g of teachers and administrators. If f i n a n c i a l obstacles prevent schools from u t i l i z i n g proper methods and i n s t r u c t i o n a l materials, then some basis f o r f i n a n c i a l assistance to school d i s t r i c t s must be i n i t i a t e d . " (p. 10)

Malcolm Skilbeck (1975) expands on the concerns of Burns and Brooks,

Cautioning against p o l i c i e s of t r a d i t i o n ,

"One way of overcoming the staleness and mindless conservatism that r e s u l t when schools refuse to examine,reflect upon, and appraise the s o c i e t i e s i n which they are functioning i s to introduce a un i v e r s a l

Page 25: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

programme of i n - s e r v i c e education. Apathy and narrowness are n a t u r a l consequences of i s o l a t i o n and neglect. The teacher who i s l e f t alone to 'get on with i t ' can a l l to e a s i l y continue throughout hi s career to reproduce the a t t i t u d e s , techniques and information with which he himself was imbued as a student." (p. 31)

It appears, then, that the i n t e r e s t s of society, students, and the

educational system would be best served through continuing i n - s e r v i c e

teacher t r a i n i n g and that i t must become a p r i o r i t y of school systems to

provide incentive f o r teachers to p a r t i c i p a t e i n that t r a i n i n g .

Although there i s recurrent mention of using external sources for

curriculum innovation i n education there i s also implied caution.

Educators are advised, for various reasons, to be acutely aware of the

reasons that they use to j u s t i f y changes i n the curriculum. As Apple (1979)

warns,

"In whose i n t e r e s t i s c e r t a i n knowledge (facts, s k i l l s , and propensities and d i s p o s i t i o n s ) taught i n c u l t u r a l i n s t i t u t i o n s l i k e schools?" (p. 16)

V . . . h i s t o r i c a l l y , curriculum theory and development has been strongly connected to and influenced by economic needs and changes." (p. 68)

"... the consciousness of curriculum workers themselves as well as other educators can be seen as l a t e n t l y p o l i t i c a l and often somewhat conservative. This i s , they use forms of thought that at l e a s t p a r t i a l l y stem from and can t a c i t l y act to maintain the e x i s t i n g s o c i a l and economic substructure and d i s t r i b u t i o n of power i n a corporate society such as our own." (p..118)

E l i s e Boulding (1978) concurs with Apple o f f e r i n g the following

i n s i g h t ,

"... educators i n :their d a i l y work are f a r more affe c t e d by ... the technological f u t u r i s t s . The technologists operate i n s i d e mega-bureaucracies and produce solutions to the problems of human welfare that frequently worsen human conditions." (p. 57)

Francis Keppel (1969), a former U.S. Commissioner of Education also warns

about change i n education,

Page 26: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 17 -

"Change i s not automatically f o r the better. In education's h i s t o r y new fads and c u l t s have often given the appearance of progress while f a i l i n g to transform education for the good of society. I t i s imperative to review a l l programs for change with a c r i t i c a l eye for the consequences, p a r t i c u l a r l y i n a time of revolution, when the pace of change discourages pause for r e f l e c t i o n . " (p. 73)

In conclusion, i t appears that there i s a d e l i c a t e tension between

curriculum developers who prefer a broader, more generalized approach to

curriculum change and various outside influences who demand s p e c i a l i z a t i o n .

The most l o g i c a l framework for c u r r i c u l a r change i n I n d u s t r i a l Education would

acknowledge the d i r e c t i o n s of the society i t serves with emphasis on ident­

i f i a b l e p r e r e q u i s i t e s and keepihg' students vocational options maximized.

Educators and curriculum t h e o r i s t s cannot predict the future and should be

wary of changing curriculum to meet predictions. The functioning member of

our society must be prepared to continuously educate himself as the demands

of the workplace change. He can only accomplish t h i s i f educators are

prepared to do the same.

Related Research i n I n d u s t r i a l Education:

The. r e l a t e d research i s divided into two areas. The f i r s t area i s

concerned with s i m i l a r research methods and the second area reviews current

research i n d r a f t i n g curriculum.

Similar Research Methods:

For t h i s area of re l a t e d research, the writer made a v i s u a l search of

the Un i v e r s i t y Microfilms International D i s s e r t a t i o n Abstracts f o r both

master's and doctoral d i s s e r t a t i o n s . A l l t i t l e s from 1967 to 1984 under

I n d u s t r i a l and Vocational Education were examined and those dealing with

curriculum development or teaching p r a c t i c e s i n r e l a t i o n to i n d u s t r i a l

requirements were selected. Almost a l l of these u t i l i z e d a survey of

industry which was often accompanied by a comparative survey of education.

Page 27: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

A number of these were reviewed f o r the purpose of developing an appropriate

questionnaire and find i n g the most appropriate methods and procedures f o r

conducting a s i m i l a r survey.

There are r e l a t i v e l y few research studies i n I n d u s t r i a l Education and

even fewer that are involved i n surveying industry. \:fnte";^.est'lt)iffialT'e','','li<>wevBr

appears to be the most popular and the most successful survey method .used i n

I n d u s t r i a l Education curriculum development.

Hoover (1967) designed and mailed p a r a l l e l questionnaires to selected

metalworking i n d u s t r i e s and to colleges o f f e r i n g courses i n metalworking.

His survey concluded that there \?as a discrepancy between the i n s t r u c t i o n

offered at the colleges and the knowledge and s k i l l s required by industry.

He also noted that new processes were taught by lec t u r e , plant v i s i t , and

contemporary p u b l i c a t i o n and that these processes were only c o n d i t i o n a l l y

being met and that I n d u s t r i a l Arts teacher education i n s t i t u t i o n s were not

changing to meet the needs of industry.

P a r d i n i (1967) made a s i m i l a r study to Hoover's that compared the

metalworking processes used i n industry with those being taught i n I n d u s t r i a l

Arts teacher education. His recommendations suggested the expansion of

course content through the use of educational media, resource people, and

i n d u s t r i a l v i s i t a t i o n s .

Berry (1967) used a questionnaire check l i s t sent to selected manu­

fac t u r i n g i n d u s t r i e s and companies i n New England to i d e n t i f y course content

for I n d u s t r i a l Arts which was r e f l e c t i v e of current i n d u s t r i a l technology.

Most notable of h i s findings was that l e s s than 10% of industry was using

new processes such as numerical c o n t r o l .

Rincfc (1968) developed an open form questionnaire f o r i d e n t i f i c a t i o n

of c u r r i c u l a r items re l a t e d to a v i a t i o n repair and service courses. His

procedure involved a jury of representative people from a v i a t i o n schools

and a v i a t i o n indoistry who ranked the importance of the topics selected f o r

i n c l u s i o n i n the questionnaire. A f t e r r e v i s i o n , the questionnaire was sent

to representative i n d u s t r i e s . He concluded that there was l i t t l e d ifference

between the requirements of industry and what was being taught i n the

tech n i c a l and secondary schools.

Moon (1968) surveyed industry i n the state of Oregon to i d e n t i f y

p r i n c i p a l process operations used i n industry that could be considered

c u r r i c u l a r components of an I n d u s t r i a l Education curriculum that r e f l e c t e d

the technology. The following selected conclusions and recommendations are

applicable to t h i s study:

"-The technological phase of the I n d u s t r i a l Arts curriculum should not only be oriented to the materials of industry but also to the technological concepts which are re l a t e d to the process operations of i n d u s t r i a l technology.

-The technological concepts upon which the I n d u s t r i a l Arts curriculum should be based are to be found i n the p r i n c i p a l process . operations of the Forming, Casting, and Molding, Shaping by Cutting, Assembly, and A u x i l l i a r y areas of i n d u s t r i a l a c t i v i t y .

-The I n d u s t r i a l Arts laboratory should be designed to permit the a p p l i c a t i o n of these technological concepts.

-The curriculum and the laboratory f a c i l i t i e s f o r I n d u s t r i a l Arts should have a multi-range of a c t i v i t i e s and be so f l e x i b l e that they can r e a d i l y change to keep pace with a changing technology.

- I t i s recommended that the c u r r i c u l a r components i d e n t i f i e d i n t h i s study be considered as elements of the I n d u s t r i a l Arts curriculum that w i l l r e f l e c t the technology." (p. 128-9)

Hildebrand (1974) mentions a study done by Richard Wilson f o r the

I n d u s t r i a l Education Department at the Iowa State University,

"Wilson surveyed 297 in d u s t r i e s , a r c h i t e c t s , and firms f o r the purpose of determining the number of a r c h i t e c t u r a l draftsmen needed i n the state of Iowa and to i d e n t i f y the s k i l l s and knowledge i n which the draftsmen exhibit competency. His findings indicated that employers desired draftsmen to be p r o f i c i e n t i n verbal commun­i c a t i o n s , s p e l l i n g , l i s t e n i n g , and note taking. I t was f e l t that advanced arithmetic, plane geometry, basic algebra, as well as various d r a f t i n g p r a c t i c e s , were also e s s e n t i a l . " (p.. 29)

Baker (1970) conducted a survey of I n d u s t r i a l Arts teacher education

i n s t i t u t i o n s and industry to determine the degree of u t i l i z a t i o n of computer

technology. He determined that the computer was widely accepted and used

i n business applications but i n I n d u s t r i a l Arts teacher education i t was

v i r t u a l l y ignored. He found that i t was extremely d i f f i c u l t to secure

q u a l i f i e d personnel to teach computer classes with i n d u s t r i a l a p p l i c a t i o n s .

A survey of the consumer e l e c t r o n i c s service industry was conducted by

Seigler (1970) to determine the knowledge and s k i l l requirements to be

considered i n the development of a t r a i n i n g program for service technicians.

Thorton (1971) used a survey of i n d u s t r i a l p l a s t i c s firms to enable the

se l e c t i o n of course materials for s p e c i f i c i n d u s t r i a l p l a s t i c s courses and

to plan a curriculum for t r a i n i n g teachers and technicians i n i n d u s t r i a l

p l a s t i c s . Polette (1972) sent questionnaires to industry and to teacher

education i n s t i t u t i o n s to determine areas of agreement concerning the

development of a woodworking power machine maintenance curriculum.

White (1975) conducted a study of curriculum developers i n I n d u s t r i a l

Education. He surveyed and compared a national population of developers

with a representative population from a sing l e state. Some of his findings

are relevant to t h i s study. He noted that there was l i t t l e time a v a i l a b l e

for curriculum development, that s e l e c t i n g content was a major problem, and

that information was d i f f i c u l t to obtain. Porschia (1975) also used a

questionnaire to determine core curriculum needs for an i n d u s t r i a l

technology program i n the areas of b u i l d i n g and construction, d r a f t i n g and

design, machine too l s , automotive, e l e c t r o n i c s , p r i n t i n g , and metal

f a b r i c a t i o n . He surveyed personnel d i r e c t o r s i n industry and depart­

mental administrators of i n d u s t r i a l technology programs at colleges and

u n i v e r s i t i e s .

The problem of keeping c u r r i c u l a r materials up to date has been ••...[;•

addressed by some researchers. Morgan (1978) u t i l i z e d a questionnaire

that dealt with possible future changes i n the s k i l l s and knowledge r:

required f or jobs i n the automotive manufacturing industry and Weiking

(1979) developed a trend i n d i c a t o r to enable forecasting of future changes

i n job requirements for the automotive industry and allow dducators

s u i t a b l e lead time for programme changes. As P i c k l e (1983) states,

"While I n d u s t r i a l Education curriculum and methodology must be c o n t i n u a l l y modified to r e f l e c t the technological developments occurring i n industry, the updating process has been hindered as the rate of technological change i n industry has accelerated." (p. 25)

The use of a jury i n the development of a questionnaire or i n the

analysis of the survey r e s u l t s appears to be f a i r l y common. Moore (1979)

used a panel of experts to develop, a survey questionnaire for the metal

manufacturing industries i n the state of Maine. 'The r e s u l t s of the survey

were used to e s t a b l i s h a p r i o r i t y order of competencies i n a metals

curriculum. Parmalee (1979) also used a jury of q u a l i f i e d people to

v a l i d a t e the items of h i s questionnaire before surveying manufacturers of

avi a t i o n / a v i o n i c s equipment. His survey was designed to determine e l e c t ­

ronics topics required for study by service technicians.

Awotunde (1982) used a questionnaire mailed to public u t i l i t i e s and

manufacturing companies to determine the c h a r a c t e r i s t i c s of in-plant

t r a i n i n g . He concluded that, regardless of the type of company or i t s s i z e ,

t r a i n i n g decisions were based upon s k i l l shortages, changes i n technology,

and company growth.

Although the preceding studies were selected for t h e i r common use of

the survey technique i n determining I n d u s t r i a l Education c u r r i c u l a , there

i s recurrent mention of c e r t a i n items pertinent to t h i s study. The f i r s t

of these i s the fac t that almost a l l of the studies were done because of

technological change. The second recurring item i s the acknowledgement

of the increasing rate of technological change and t h i r d i s the implied

i n a b i l i t y of present curriculum development methods to deal e f f e c t i v e l y

with the rapid change i n technology.

In summary, the preceding studies w i l l a t t e s t to the popularity and

success of the survey method of research i n I n d u s t r i a l Education.

Curriculum development i n I n d u s t r i a l Education i s v i r t u a l l y impossible

without input from representative industry and the most important c u r r i ­

culum development t o o l at t h i s time appears to be the survey questionnaire.

Drafting Curriculum Research:

For t h i s area of l i t e r a t u r e review, an Educational Resources Infor­

mation Center (ERIC) search was made and the Comprehensive D i s s e r t a t i o n

Abstracts were used.

Merl Case (1971) mentions two studies concerned with computer graphics.

Hornbuckle (1967) did a study on the designing of equipment with the aide of

a computer and Barber (1967) made a study of i n s t r u c t i o n a l methods required

to implement r e l i a b l e manufacturing and computer systems. Case mentions

that h i s i n i t i a l search revealed a minimal amount of research concerning

computer graphics, e s p e c i a l l y i n education, but a great quantity of

p e r i o d i c a l l i t e r a t u r e . He concludes h i s l i t e r a t u r e review with the

following:

"A number of good curriculum studies have been made f o r other areas of I n d u s t r i a l Arts, but few were found which r e l a t e to teaching the new methods of d r a f t i n g . In l i g h t of the l i m i t e d number of research studies on computer graphics, they are of minimal use i n the development of computer graphics curriculum.

The l i t e r a t u r e review does i n d i c a t e that there needs to be a change i n our d r a f t i n g curriculum to incorporate the current p r a c t i s e s used by industry. I t i s a r e s p o n s i b i l i t y of the teacher educator to take the lead i n the development and improvement of curriculum for the preparation ofhteachers I n th i s area of I n d u s t r i a l .Arts. V (p. 41)

Case (1971) u t i l i z e d two questionnaires; one for i n d u s t r i a l educators and

one for personnel working with computer graphics i n industry. The r e s u l t s

of h i s study allowed him to state a number of conclusions, i m p l i c a t i o n s , and

recommendations. Some of these have been selected for t h e i r relevance to

t h i s study.

" - I n s u f f i c i e n t funds and lack of f a c i l i t i e s were the primary reasons for not o f f e r i n g computer graphics courses within the I I n d u s t r i a l Arts department.

-A majority of the schools have equipment a v a i l a b l e , with the exception of a p l o t t e r and co n t r o l , to teach a course i n computer graphics.

-A number of the p a r t i c i p a t i n g i n s t i t u t i o n s did not have an :vu in s t r u c t o r within the I n d u s t r i a l Arts department q u a l i f i e d to teach computer graphics.

-The primary a p p l i c a t i o n of computer graphics i n industry i s to depict engineering drawings.

-Speed, cost-saving, and accuracy are the primary reasons for the use of computer graphics i n industry.

-Computer graphics, as a new method of defining items g r a p h i c a l l y , does not preclude the need for a basic understanding of pr o j e c t i o n .

- I f I n d u s t r i a l Arts departments are to a t t a i n t h e i r objective of in t e r p r e t i n g contemporary industry, curriculum must be revised to r e f l e c t those processes being u t i l i z e d by industry." (p. 128—1-35)

Page 33: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

Hildebrand (1974) made a comparison of i n d u s t r i a l d r a f t i n g practices

with those taught i n I n d u s t r i a l Arts for the purpose of determining the

relevance of curriculum to i n d u s t r i a l p r a c t i c e . He constructed two

questionnaires; one for industry and one for I n d u s t r i a l Arts teacher

education i n s t i t u t i o n s . He was interested i n knowing where industry

acquires draftsmen, how educators keep themselves and t h e i r curriculum

up to date, what differences there were between i n d u s t r i a l and c u r r i c u l a r

d r a f t i n g p r a c t i c e s , and which areas of d r a f t i n g were changing enough to

warrant curriculum content r e v i s i o n .

Hildebrand's conclusions are pertinent to the d i r e c t i o n of t h i s

study.

"1. Drafting students need a general understanding of a l l facets of i n d u s t r i a l processes with s p e c i a l emphasis on a p p l i c a t i o n of d r a f t i n g knowledge, p r i n c i p l e s , and p r a c t i c e s .

2. English, mathematics, s t a t i s t i c s , and problem solving and c r e a t i v e a b i l i t i e s are a must f o r any person employed i n :". ' i n d u s t r i a l d r a f t i n g .

3. A l l new equipment, materials, ..processes, and practices which can f i n a n c i a l l y be provided should be introduced i n the I n d u s t r i a l Arts d r a f t i n g program. Current areas such as a u t o s h i f t d r a f t i n g tables, c a l c u l a t o r s , computers, metric measurement and dimension­ing, and the reproduction processes (microfilm and microfiche) are e s p e c i a l l y important.

4. With I n d u s t r i a l Arts i n s t i t u t i o n s d i r e c t l y or i n d i r e c t l y t r a i n ­ing approximately one-fourth of a l l i n d u s t r i a l draftsmen, i t i s e s s e n t i a l for I n d u s t r i a l Arts i n s t i t u t i o n s to e s t a b l i s h a close working r e l a t i o n s h i p with industry. A system f o r curriculum development and/or r e v i s i o n should be developed to ensure that I n d u s t r i a l Arts i n s t i t u t i o n s maintain a close approximation of i n d u s t r i a l p r a c t i c e s . " (p. v)

Hildebrand recommended that further study be directed towards the use of

computer graphics i n industry and i t s e f f e c t on I n d u s t r i a l Arts d r a f t i n g

curriculum and also that a system for d r a f t i n g curriculum r e v i s i o n be

Page 34: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 25 -

developed to keep course content current with i n d u s t r i a l p r a c t i c e s .

Ward (1979) surveyed i n d u s t r i a l concerns for the purpose of developing

curriculum for a Drafting and Design Technology Program for a Northwest

F l o r i d a j u n i o r college. His recommendations were quite s i m i l a r to those

of Hildebrand.

"1. Drafting and Design Technology educators should make concentrated e f f o r t s to develop and maintain communications with l o c a l :' i n d u s t r i a l concerns.

2. I n d u s t r i a l expertise should be considered a p o t e n t i a l resource for program development and should be used to supplement and upgrade dr a f t i n g and design technology programs.

3. Follow-up studies should be conducted p e r i o d i c a l l y to e s t a b l i s h c r i t e r i a for determining the effectiveness of d r a f t i n g and design technology programs as perceived by industry personnel employing graduates of such programs.

4. Pe r i o d i c updating of programs should be accomplished through the use of questionnaires.

5. Drafting and Design Technology educators should stay current with i n d u s t r i a l developments and progress." (p. 68)

P i c k l e (1983) surveyed high technology industries and i n d u s t r i a l

technology educational i n s t i t u t i o n s i n order to i d e n t i f y a high technology

curriculum. He found that there was a s i g n i f i c a n t d i f f e r e n c e between

i n d u s t r i a l needs for high technology and the courses being offered at

representative educational i n s t i t u t i o n s . The most conducive course for

implementing a high technology program i n the curriculum was i d e n t i f i e d as

Computer Aided Design.

Ayers (1971) conducted a survey of technical schools and industry

i n Ohio to confirm that the schools did provide s u f f i c i e n t s k i l l s i n

Mathematics and Science for d r a f t i n g technicians to meet i n d u s t r i a l require­

ments. Groom (1982) used computer graphics as a teaching t o o l f o r f i r s t -

semester engineering graphics. The treatment group learned a d d i t i o n a l :".

information and improved t h e i r a t t i t u d e toware computer graphics while

performing as w e l l as the control group on short-term weekly quizzes and

better on the long-term examination.

Very few studies have been done that p e r t a i n d i r e c t l y to the d r a f t i n g

curriculum at the secondary school l e v e l . One of these has been done by

Tedesco (1974) who surveyed senior high schools and a r c h i t e c t u r a l firms

i n Orange County,.California to compare the dr a f t i n g techniques being taught

with those being used p r o f e s s i o n a l l y . He found s i g n i f i c a n t differences i n

l e t t e r i n g p r a c t i c e s with regard to speed, l e g i b i l i t y , and s t y l e techniques.

A r c h i t e c t s were more concerned with codes, c a l c u l a t i o n s , specifications,, and

construction methods while d r a f t i n g teachers placed more emphasis on

perspective, rendering, and presentation drawings.

Another secondary school study was made by McMillan (1981) which

found a p o s i t i v e c o r r e l a t i o n between d r a f t i n g and mathematical a b i l i t i e s .

She also noted that there was no differe n c e between male and female students

i n t h e i r mathematical or dr a f t i n g a b i l i t i e s .

P e r i o d i c a l L i t e r a t u r e of Interest:

There i s a vast amount of p e r i o d i c a l l i t e r a t u r e dealing with computer

aided d r a f t i n g and rela t e d technology but very l i t t l e of i t i s concerned

with the s k i l l s or t r a i n i n g involved. This writer examined the abstracts

presented i n a l l back issues of the Canadian Manufacturer's Association

CAD/CAM newsletter to locate a r t i c l e s that dealt with the impact of t h i s

technology on education. Other p e r i o d i c a l s that presented r e l a t e d a r t i c l e s

included I n d u s t r i a l Education, Technology West, Canadian Repro-Draft, Byte,

Engineering Digest, Design Engineering, Fine Homebuilding, Computing Now, and

Popular Computing magazines. Newspaper a r t i c l e s from the Vancouver Sun

were also included i n t h i s survey.

Keenan (1982) i n an a r t i c l e on student CAD t r a i n i n g stated that

p i l o t CAD t r a i n i n g programs at f i v e vocational t e c h n i c a l schools i n

Minnesota resulted i n more complete d r a f t i n g graduates. The exposure to

CAD reduced the amount of on-the-job t r a i n i n g required and provided them

with more marketable s k i l l s . The program was i n i t i a t e d when a committee

of people from education and industry i d e n t i f i e d computer graphics as an

area of vocational t r a i n i n g necessary to meet the requirements of l o c a l

industry. Instructors f i n d the CAD systems easy to l e a r n and highly

motivational for students. The I.T.T. Technical I n s t i t u t e i n Dayton,

Ohio also found that p o t e n t i a l employers wanted graduates with CAD s k i l l s .

(Engraf newsletter, June, 1984).

Brummel (1984) i n a d e s c r i p t i o n of student d r a f t i n g programs i n

Ontario mentions the introduction of CAD at the secondary l e v e l . The

objective with CAD was to introduce and acquaint students with CAD systems

p o t e n t i a l and remove the mystique of the equipment rather than shortcut

on technique or i n s t r u c t i o n . Apparently the introduction was successful

as an a r t i c l e i n The Vancouver Sun newspaper reported i n May, 1985, that

the Accugraph Corp. of Toronto had closed a deal with the Ontario M i n i s t r y

of Education to develop a b i l i n g u a l CAD package for the province's schools.

An advertisement for the Vancouver Vocational I n s t i t u t e i n the

February, 1985, e d i t i o n of Canadian Repro-draft magazine makes the following

claim:

"Among the 500 best jobs for the future, according to a McGraw-H i l l p u b l i c a t i o n of the same name, i s that of a computer aided d r a f t ­ing technician. Author Marvin Creton estimates some 300,000 of these technicians w i l l be required i n the U.S. over the next ten years. Drawing from the U.S. f i g u r e , we can a n t i c i p a t e Canada's need at about 30,000. Then, there are thousands more a r c h i t e c t s , engineers,

Page 37: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

i n t e r i o r designers, and pattern makers who w i l l need computer > aided d r a f t i n g i n t h e i r work. The demand for t h i s s k i l l i s staggering." (p. 11)

The a r t i c l e mentions that the college a n t i c i p a t e s the eventual l i n k i n g

of t h e i r CAD system with the computer aided manufacturing equipment i n i t s

machine shop. This appears to be the technological trend i n industry.

Blauth (1981) predicts that CIM (computer-integrated manufacturing) w i l l

provide the greatest p o t e n t i a l technology f o r improving i n d u s t r i a l

p r o d u c t i v i t y i n the 1980's, using the synergism of CAD and CAM. He

concludes h i s address with the following statement:

"The i n t e g r a t i o n of engineering's CAD database with manufacturing's CAM database w i l l y i e l d the ultimate benefit to p r o d u c t i v i t y by encouraging "designing for manufacturability' and by optimizing production e f f i c i e n c i e s . " (p. 19)

Jadrnicek (1984), Adlard (1984), and Lardner (1983) a l l mention the advent

of CIM as the replacement for CAD/CAM. Lardner maintains that the t r a n s i t i o n

into CIM w i l l be the key to regaining manufacturing competitiveness and

Adlard also mentions increased a b i l i t y to compete i n world markets.

Computer integrated manufacturing w i l l s t i l l require CAD s k i l l s .

O i l i n g (1983), i n a study of numerical control education i n the U.S.,

acknowledges the threat of automation to the u n s k i l l e d worker and d i r e c t s

the educational system to disseminate new technological developments to

the labour force as quickly as pos s i b l e . He states,

"Education, where problems ultimately a r i s e from i n d u s t r i a l , economic, and s o c i a l changes, must f i n d ways of preparing i t s students to meet these ever-changing conditions and demands. The society, where i n d u s t r i a l f a c i l i t i e s become highly automated, needs more knowledge power than phy s i c a l power p a r t i c u l a r l y i n the area of Computer Aided Design and Computer Aided Manufacturing (CAD/CAM)." (p. 22)

Page 38: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

"A deliberate and systematic e f f o r t must be made not only to keep pace with but to a n t i c i p a t e the increased educational demands of the changing i n d u s t r i a l world." (p. 24)

Pipes (1982) i n a supportive assessment of the applications of CAD/CAM

technology also i d e n t i f i e d a major problem of education and t r a i n i n g i n

t h i s technology i n the United Kingdom. Bartholemew (1983) surveyed the

technological education a v a i l a b l e i n B r i t i s h Columbia. Labour market

predictions that indicated a shortage of s k i l l e d workers over the next

decade prompted an assessment of the implications of high technology and

the implementation of a number of appropriate t r a i n i n g programs.

Summary:

The review of the l i t e r a t u r e established that a v a r i e t y of influences

determine the c u r r i c u l a of our schools. Business i n t e r e s t s , i n general, were

proponents of more s p e c i a l i z e d curriculum while curriculum developers favoured

a more moderate and f l e x i b l e approach. : The d i s t i n c t i o n between curriculum

that i s r e f l e c t i v e of society and one that i s s p e c i a l i z e d i s not c l e a r .

Educators were urged to develop curriculum that provided a broad base of inform­

ati o n and s k i l l s that would allow a continuum of learning throughout t h e i r

students' l i v e s .

Studies of curriculum content i n I n d u s t r i a l Education were p r i m a r i l y

concerned with keeping course material current and r e l a t i v e to the needs of

l o c a l industry. The research seemed designed to increase s p e c i a l i z a t i o n f o r

l o c a l industry, at l e a s t at the post secondary l e v e l . The questionnaire

survey was the predominant and most economical method of gathering information

from industry and educators for these studies.

The number of studies dealing with d r a f t i n g curriculum was very small

and most were concerned i n some way with adjusting to the rapid changes i n

d r a f t i n g technology. Only two studies were located that dealt with

Page 39: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 30 -

d r a f t i n g curriculum i n secondary schools and neither of these was concerned

with changes i n the technology. There were no studies located at t h i s time

that were concerned with secondary school curriculum adaptation to the

changing technology of d r a f t i n g .

Current p e r i o d i c a l l i t e r a t u r e indicates a growing need f o r d r a f t i n g

technicians with CAD s k i l l s and a demand for the appropriate t r a i n i n g

programs. Using CAD i n t h e i r d r a f t i n g programs, i n s t r u c t o r s f i n d increased

motivation and better job opportunities for t h e i r students.

CHAPTER THREE

METHODS AND PROCEDURES

The main purpose of t h i s study was to i d e n t i f y the p r e r e q u i s i t e

s k i l l s and knowledge most appropriate for t r a i n i n g and/or employment i n

computer aided d r a f t i n g and to make recommendations for the necessary

secondary school c u r r i c u l a r r e v i s i o n . The data was obtained through the

use of survey questionnaires sent to s i x t y - f i v e B r i t i s h Columbia firms

using CAD technology and to f i f t e e n educational i n s t i t u t i o n s o f f e r i n g

t r a i n i n g i n computer aided d r a f t i n g .

Construction of the Questionnaire:

The questionnaires were developed through comparison with the survey

instruments used i n s i m i l a r studies. The topics were selected from an

analysis of curriculum guide, d r a f t i n g textbook, and standard manual

items. The w r i t e r made a number of r e v i s i o n s a f t e r interviewing college

and u n i v e r s i t y i n s t r u c t o r s , CAD software developers, CAD operators, high

technology personnel, and CAD vendors as w e l l as completing a 120 hour

college CAD course. The two questionnaires are v i r t u a l l y i d e n t i c a l

except for wording appropriate to the respondents. The i n t e n t i o n was to

e l i c i t the same type of information from two d i f f e r e n t populations. F i n a l

r e v i s i o n s were made on the recommendations of the thesis committee.

In order to generate the greatest response to the survey, the

questionnaire was kept as b r i e f as possible and used only closed form

ranking or multiple choice questions. Provision was made for respondents

to add items or to make comments or suggestions.

Page 41: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 32 -

A p i l o t study was made to test the questionnaire. The respondents

were a college CAD i n s t r u c t o r , a CAD operator, a CAD software developer,

and a CAD system vendor. A l l of the respondents were interested and

cooperative. Interviews a f t e r the completion of the questionnaire did

not generate any further r e v i s i o n .

The questionnaires were designed to obtain the following information:

1. The areas of d r a f t i n g where CAD use i s more prevalent.

2. The s i z e and/or type of the CAD systems i n use.

3. The ease of operation of the d i f f e r e n t CAD systems.

4. The amount of money invested i n the CAD systems.

5. The education of the people operating CAD systems.

6. The educational background of candidates f o r CAD t r a i n i n g .

7. The methods whereby CAD operators received t h e i r CAD t r a i n i n g .

8. The most s u i t a b l e methods to receive CAD t r a i n i n g .

9. The preferences of industry as to the education or experience

of t h e i r CAD operators.

Selection of the Sample Populations:

The sample of businesses using CAD systems i n B r i t i s h Columbia was

extremely d i f f i c u l t to assemble. B r i t i s h Columbia industry i s p r i m a r i l y

resource based. Forestry, mining, f i s h i n g , and tourism constitute the

Page 42: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 33 -

l a r g e s t portion of the p r o v i n c i a l economy. The recession of recent

years has done l i t t l e to encourage investment i n new technology and

government attempts of encourage secondary industry have had l i t t l e

success. As a r e s u l t , the number of companies u t i l i z i n g CAD technology

i n B r i t i s h Columbia i s predictably small.

There i s no dir e c t o r y of businesses i n B r i t i s h Columbia that use

CAD. In order to do t h i s study, a d i r e c t o r y had to be assembled. The

B r i t i s h Columbia Innovations o f f i c e offered the mailing l i s t f o r the now

defunct Western Foundation for the Advancement of I n d u s t r i a l Technology.

B r i t i s h Columbia Research did have a f a i r l y large sample of high technology

oriented companies but could not divulge proprietory information, and most

CAD system vendors had c o n f i d e n t i a l customer l i s t s . Through employer

l i s t s provided by some of the colleges and c a r e f u l scrutiny of advertise-

ments.-in engineering and high technology magazines a modest di r e c t o r y was

assembled. The s i x t y - f i v e businesses selected do not represent a random

sample, however, they do represent the majority of such businesses i n

B r i t i s h Columbia.

The f i f t e e n i n s t i t u t i o n s o f f e r i n g CAD t r a i n i n g represent the t o t a l

number that o f f e r such courses i n B r i t i s h Columbia. One more has since

invested i n t h i s technology, but w i l l not be o f f e r i n g courses u n t i l t h i s

f a l l . This information i s r e a d i l y a v a i l a b l e at most secondary school

counselling o f f i c e s .

Procedure:

The questionnaires, together with a cover l e t t e r and a stamped,

addressed return envelope, were sent to the s i x t y - f i v e businesses and the

f i f t e e n educational i n s t i t u t i o n s on A p r i l 10, 1985. A f t e r four weeks,;.a

Page 43: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

follow-up l e t t e r with another questionnaire and stamped return envelope was

sent to those who had not responded to the f i r s t questionnaire. Any

questionnaires returned a f t e r June 10, 1985 were not included i n the

study. For v a l i d r e s u l t s , the percentage of return of questionnaires

from the two populations was t e n t a t i v e l y set at 60%

Treatment of Data:

The returned questionnaires were tabulated and the r e s u l t s presented

i n graphical format to permit comparison between the two populations.

Where questions required the ranking of p a r t i c u l a r items according to

importance or preference, the value of 1 was given to the most important

or most preferred and the value of 5 was given to the l e a s t important.

When c a l c u l a t i n g the mean l e v e l of importance or preference, values

between 1.0 and 2.0 would indicate an item of high importance while a

value between 4.0 and 5.0 would i n d i c a t e low importance. The comparison

between populations was not the intent of the study but i s added to

increase the understanding of the problem.

CHAPTER FOUR

PRESENTATION OF FINDINGS

The purpose of t h i s study was to determine, through a survey of

industry and educational i n s t i t u t i o n s , the p r e r e q u i s i t e s k i l l s and knowledge

for t r a i n i n g and/or employment i n the f i e l d of computer aided d r a f t i n g . Two

p a r a l l e l , closed form questionnaires were sent to representative businesses

and educational i n s t i t u t i o n s and the returned data tabulated and analyzed.

The survey was intended to i d e n t i f y areas of c u r r i c u l a r strengths and

weaknesses i n the secondary school system and also to acquaint educators

with technological trends i n industry. The data from the two populations

was tabulated separately to show possibly, divergent points of view.

Survey Response:

S i x t y - f i v e businesses i n B r i t i s h Columbia, i d e n t i f i e d as users of CAD

technology, were sent questionnaires. Of these s i x t y - f i v e , four firms or

s i x percent were no longer i n business and the questionnaires were returned.

The f i g u r e of s i x percent corresponds very well to a recent a r t i c l e i n the

business section of The Vancouver Sun which mentioned that s i x percent of

B r i t i s h Columbia industry had l e f t the province i n the l a s t year. Of the

remaining sixty-one businesses, f i f t y or 82% returned the questionnaires.

Nine of these (15% of the sample) were not d i r e c t users of CAD (some were

software developers or consultants), nine more were i n the process of

evaluating or i n s t a l l i n g CAD.systems, and the remaining thirty-two (52% of

the sample) provided completed questionnaires.

Nine of the f i f t e e n educational i n s t i t u t i o n s (60%) returned completed

Page 45: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 36 -

questionnaires. The sample of f i f t e e n i n s t i t u t i o n s represents the t o t a l

number of i n s t i t u t i o n s o f f e r i n g CAD t r a i n i n g of any kind at t h i s time i n

B r i t i s h Columbia. Included with the s i x non-respondents are a l l three

B r i t i s h Columbia u n i v e r s i t i e s . This may be a r e s u l t of the timing of the

study which coincided with the end of the academic year. Unfortunately

the r e s u l t s may tend to be somewhat biased i n favour of the regional

colleges whose returned questionnaires form the greater part of the

i n s t i t u t i o n a l data. A graph of the survey response i s included as Figure 1.

Areas of CAD Use:

The businesses surveyed indicated that t h e i r major use of CAD was for

mechanical and e l e c t r o n i c s d r a f t i n g . Both of these areas received 50%

response. (Many of the businesses surveyed indicated involvement i n more

than one area of d r a f t i n g producing a survey t o t a l that exceeds 100%)

The next major area was s t r u c t u r a l (37%), followed by a r c h i t e c t u r a l and

cartographic (survey, mapping, topography) with 34% each. A few businesses

had s p e c i f i c uses f o r CAD not included i n the survey. These include two

firms involved i n naval architecture, one i n f l u i d i c s , and one i n producing

process flowsheets.

The educational i n s t i t u t i o n s had s i m i l a r emphasis i n t h e i r CAD t r a i n i n g

courses. A r c h i t e c t u r a l and c i v i l d r a f t i n g both received 56% response,

followed by mechanical and s t r u c t u r a l at 44% each. Process piping was the

only area of CAD t r a i n i n g not included i n the survey to be mentioned by an

i n s t i t u t i o n . The graphics and HVAC (heating, v e n t i l a t i o n , and a i r condition-

ind) areas received low response from both populations.

The data f o r t h i s question should not be used to in d i c a t e the prevalence

of CAD i n s p e c i f i c f i e l d s ; rather i t should indicate that CAD i s being used.

i n v i r t u a l l y a l l areas of d r a f t i n g . The tabulated responses from the

business survey only serve to describe that sample population. S i m i l a r l y ,

the response from the t r a i n i n g i n s t i t u t i o n s describes the emphasis of i t s

CAD courses. A graph of the response to t h i s question i s included as

Figure 2.

CAD System Description:

The question dealing with the type of CAD system being used was

designed mainly to determine the degree to which personal computers were

being used for CAD purposes i n industry and for t r a i n i n g purposes. Few

businesses or educational i n s t i t u t i o n s can a f f o r d the massive investment

required for dedicated or mainframe CAD systems. The personal computer

based CAD systems appear to be performing nearly as well as the large

systems and at much less cost.

Fourteen businesses (44%) and f i v e i n s t i t u t i o n s (56%) indicated that

t h e i r systems were personal computer based. Rather than attempting to

describe the various combinations of hardware and software i n use, t h i s

writer has included an appendix of CAD system.descriptions offered by the

questionnaire respondents. This w i l l be of much more use to educators i n

determining CAD system and t r a i n i n g requirements. Figure 3 presents the

graph of the response to t h i s question.

CAD System Ease of Operation:

It was o r i g i n a l l y thought that there might be a r e l a t i o n s h i p between

the s i z e or complexity of a CAD system and the r e l a t i v e ease of operating

i t . Many of the early mainframe CAD systems were plagued with programming

problems and were d i f f i c u l t to operate i n comparison to the personal computer

systems that are entering the market now. The response to t h i s question

in d i c a t e s that t h i s may be the case. Figure 4 i l l u s t r a t e s that most of :.

the CAD systems i n the survey sample are considered as r e l a t i v e l y easy

to operate but there i s a small number of each group that suggest some

degree of d i f f i c u l t y . When these i n d i v i d u a l questionnaires were analyzed,

i t appeared that 88% of the businesses and 67% of the educational i n s t i t u t i o n s

that expressed d i f f i c u l t y i n operating t h e i r CAD systems had large mainframe

or dedicated systems. Only 14% of the businesses and 11% of the educational

i n s t i t u t i o n s u t i l i z i n g personal computer based CAD systems expressed any

d i f f i c u l t y of operation.

CAD System Costs:

The cost of a CAD system i s r e l a t i v e to the number of work stations

that i t can support. The large mainframe and dedicated systems have the

power to handle a large number of users simultaneously and, for considerably

les s cost, personal computers can be networked to perform almost as w e l l .

Those survey respondents who indicated system costs i n excess of $75,000.

included two with networked personal computer systems. The important aspect

of t h i s portion of the survey i s the large number of businesses (40%) and

educational i n s t i t u t i o n s (44%) with CAD systems i n operation for le s s than

$25,000. System costs are indicated i n Figure 5.

CAD Training Candidates:

The educational i n s t i t u t i o n s responding to t h i s question indicated

that the majority of the i n d i v i d u a l s seeking t r a i n i n g i n computer aided

d r a f t i n g had s k i l l s or t r a i n i n g i n a re l a t e d area and were upgrading them­

selves. Draftspersons were mentioned most often (78%) followed by

professionals and others (teachers). The professionals and others have

been assessed together because a l l of the others mentioned i n the question­

naires were professionals of some sor t . (See Figure 6)

CAD Operator Background:

Businesses indicated that t h e i r CAD operators were usually d r a f t s -

persons retrained for t h e i r CAD systems. None of the respondents had

obtained CAD draftspersons d i r e c t l y from an educational i n s t i t u t i o n .

The other i n d i v i d u a l s using the CAD systems were engineers, a r c h i t e c t s ,

designers, and technicians. (See Figure 7)

CAD Operator Training:

Only 12% of the business survey indicated that t h e i r operators had

received t h e i r t r a i n i n g through an educational i n s t i t u t i o n . The rest had

obtained t r a i n i n g through s e l f - t e a c h i n g , in-house courses, vendor courses,

or a combination of these. This i s an i n d i c a t i o n of the lack of a v a i l a b i l i t y

of appropriate courses for employees at the time that the t r a i n i n g was required.

Most of these people would have needed t r a i n i n g before there were any courses

a v a i l a b l e p u b l i c l y . In support of t h i s , most of the businesses surveyed

indicated that they would prefer to h i r e a draftsperson with CAD s k i l l s .

Figure 8 i n d i c a t e s the t r a i n i n g of present CAD operators and Figure 9

indicates the h i r i n g preferences of the businesses surveyed.

Business H i r i n g Preferences for CAD Operators:

The time and cost of t r a i n i n g a person to operate a CAD system would

be expected to influence an employer to h i r e a draftsperson already trained

i n CAD, yet a s u r p r i s i n g number indicated that they would prefer to t r a i n

a good draftsperson, technician, or p r o f e s s i o n a l on the firm's CAD system.

The mean ranking f o r t h i s item i s j u s t s l i g h t l y i n favour of a CAD d r a f t s -

person, followed c l o s e l y by a regular draftsperson or technician/technologist.

Candidate Preference of CAD Training I n s t i t u t i o n s :

I n s t i t u t i o n s indicated that they strongly preferred to teach computer

aided d r a f t i n g to regular draftspersons. Instructors obviously do not

have a choice of who they teach.a:, This aspect i s usually c o n t r o l l e d through

the admission requirements of the i n s t i t u t i o n , however they #jf©jaaM&v., f i n d i t more rewarding to teach the i n t r i c a c i e s of t h e i r CAD system to

someone with some background i n d r a f t i n g or design. (See Figure 8b)

CAD Training Methods Preferred by Educational I n s t i t u t i o n s :

Question 6 of the questionnaire sent to educational i n s t i t u t i o n s

asked for respondents to i n d i c a t e the best method of receiving CAD

t r a i n i n g . Figure 9 presents the response to t h i s question. The tabulated

data i s s i m i l a r to the data from Question 1 i n that i t only serves to

describe the sample population. The respondents i n t h i s case were

obviously biased i n favour of t h e i r p a r t i c u l a r method of t r a i n i n g . The

sample's high proportion of regional colleges mentioned previously i s

r e f l e c t e d i n the 78% response to t h i s t r a i n i n g method. I t i s notable

that the i n s t i t u t i o n s sampled did give c r e d i t to vendor's courses and 1

in-house t r a i n i n g as v i a b l e methods of CAD t r a i n i n g . Even self- t e a c h i n g

received an 11% response.

Importance Ranking of Selected Manual, Cognitive, and I n d u s t r i a l S k i l l s :

The CAD operator may require c e r t a i n s k i l l s that are not necessary

for manual d r a f t i n g . In an e f f o r t to determine i f t h i s i s so and to ..

i d e n t i f y such s k i l l s , businesses and educational i n s t i t u t i o n s were asked

importance of the items i n each category. Following the ranking, respondents

were asked to i d e n t i f y the. si n g l e most important, s k i l l , i f any, from the

previous categories. In order to accommodate the i n c l u s i o n of c e r t a i n

s k i l l s not mentioned, a blank response l a b e l l e d "other" was added to the

manual and cognitive categories.

To present a v i s u a l image of the ranking for t h i s question, bar graphs

were prepared that show h o r i z o n t a l bars whose length corresponds d i r e c t l y

to the mean l e v e l of importance accorded that s k i l l . An item of very

l i t t l e importance could receive a mean ranking of 5.00 and would not

generate a bar on the graph. An item of high importance could receive a

mean ranking of 1.00 and would generate a f u l l length bar on the graph.

(A s i m i l a r treatment of data was used to generate the bar graphs i n

followed by keyboard s k i l l s , perspective drawing and word processing, i n

that order of rank. The ranking was the same i n both surveys as shown

i n Figure 10.

Figure 11 shows the ranking of selected cognitive s k i l l s . Although

both surveys considered a n a l y t i c geometry to be the most important, they

Many educators and businesses f e e l that a knowledge of i n d u s t r i a l

methods and processes i s very important for a draftsperson. A number of

such iareas of i n d u s t r i a l knowledge were placed i n a t h i r d category of

selected i n d u s t r i a l s k i l l s i n order to determine i f there was any s p e c i f i c

area that should receive emphasis i n preparing students for CAD. The

ranking of these items was r a d i c a l l y d i f f e r e n t between surveys. Businesses

considered the e l e c t r o n i c s area to be of most importance followed very

c l o s e l y by machining and metal f a b r i c a t i o n . Least important were millwork

and cabinetmaking s k i l l s . This writer f e e l s that the ranking of these

p a r t i c u l a r s k i l l s by business i s r e l a t i v e to the areas of industry that

the businesses are involved.in. An analysis of the response to t h i s

p a r t i c u l a r question does i n d i c a t e that t h i s i s the case. A comparison of

the response to Question 2, (which describes the areas of CAD use), to the

ranking of these s k i l l s by business does indi c a t e a strong c o r r e l a t i o n .

As with the response to Question 2, the ranking of t h i s category only

serves to describe the survey population.

The ranking of i n d u s t r i a l s k i l l s by the t r a i n i n g i n s t i t u t i o n s s i m i l a r l y

i ndicates course emphasis, again corresponding very c l o s e l y to the response

to Question 2. The educational i n s t i t u t i o n s surveyed indicated r e s i d e n t i a l

framing and f i n i s h i n g s k i l l s to be the most important, followed by

machining, metal f a b r i c a t i o n , millwork, and cabinetmaking. E l e c t r o n i c s

s k i l l s were considered l e a s t important for CAD t r a i n i n g . (See Figure 12)

Of a l l the s k i l l s mentioned, the s i n g l e most important s k i l l was

considered to be manual d r a f t i n g by both the business survey (53%) and the

t r a i n i n g survey (67%). A number of items were mentioned here that could a l l

be loo s e l y categorized as problem solving a b i l i t i e s . These include

Page 59: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

- 50 -

a d a p t a b i l i t y , s p a t i a l a n a l y s i s , design techniques, thinking a b i l i t y , etc.

If these are grouped together they form 33% of the t r a i n i n g survey response

and 32% of the business survey response to t h i s question.

To summarize the response to t h i s question, both businesses and

t r a i n i n g i n s t i t u t i o n s involved with CAD consider manual d r a f t i n g s k i l l s

and good problem solving a b i l i t y to be the most important p r e r e q u i s i t e s f or

CAD t r a i n i n g or employment.

Importance of Selected Drafting S k i l l s i n Relation to CAD Training

or Employment:

Question 9 of the survey asked respondents to i n d i c a t e the importance,

r e l a t i v e to CAD t r a i n i n g or employment, of c e r t a i n d r a f t i n g s k i l l s presently

being taught as part of the d r a f t i n g curriculum i n B r i t i s h Columbia secondary

schools. These s k i l l s were selected from the 1977 B r i t i s h Columbia

I n d u s t r i a l Education Curriculum Guide.

A rank of 5 Indicated the s k i l l to be of low importance and a rank of 1

indicated the s k i l l to be very important. The mean p r i o r i t y r a t i n g of each

item was calculated f o r both surveys and displayed i n bar graph format i n

Figure 13. As shown on the graph, businesses and t r a i n i n g i n s t i t u t i o n s were

remarkably consistent i n t h e i r assessment of d r a f t i n g s k i l l importance. The

only areas of marked contrast were cam and gear development (0.56 difference)

and ve r n i e r protractor reading (0.53 d i f f e r e n c e ) .

The advent of computer aided d r a f t i n g technology has made the a c q u i s i t i o n

of c e r t a i n d r a f t i n g s k i l l s a questionable pursuit. It would seem that such

f i n e motor s k i l l s as tracing, inking, l e t t e r i n g , and drawing consistent

linework would be of much l e s s importance i n d r a f t i n g courses. The response

to Question 9 indicates that t h i s i s true to a c e r t a i n degree. What i s more

important i n t h i s question i s the importance given c e r t a i n other items.

Dimensioning to CSA standards was given the highest p r i o r i t y r a t i n g , followed

very c l o s e l y by p i c t o r i a l drawing (isometric/oblique), a u x i l i a r y views,

revolutions, perspective drawing, and freehand sketching. A l l of these

items, except for dimensioning, require the a b i l i t y to think i n three

dimensions. In other words, d r a f t i n g educators should be emphasizing the

three dimensional aspect of d r a f t i n g ; the fa c t that the image on paper

represents a s o l i d object that can be manipulated and viewed from d i f f e r e n t

angles, not n e c e s s a r i l y the t r a d i t i o n a l orthographic angles.

Secondary School C u r r i c u l a r Change or Emphasis I d e n t i f i e d as Being

B e n e f i c i a l to Student CAD Training or Employment:

Figure 14 displays the tabulated response to Question 10 of the survey

questionnaire. CAD t r a i n i n g i n s t i t u t i o n s and businesses using CAD were

asked to' i d e n t i f y which areas of the secondary school curriculum, i f any,

that they would change or emphasize to better prepare students for further

t r a i n i n g and/or careers i n CAD. The introduction of computer aided d r a f t i n g

at the secondary l e v e l was i d e n t i f i e d by 78% of the i n s t i t u t i o n s and 72% of

the businesses as the best method of preparing students. This was followed

by the introduction of more d r a f t i n g courses. The business survey indicated

that a knowledge of i n d u s t r i a l processes was j u s t as important as more

dra f t i n g courses while the t r a i n i n g i n s t i t u t i o n s were more concerned with

better Math and English s k i l l s . The low response by both surveys to cont­

inuing with present programs indicates a need for some c u r r i c u l a r r e v i s i o n

i n t h i s respect.

Purpose of the Study Reviewed:

The survey indicated that:

1. Computer aided dr a f t i n g was i n use for v i r t u a l l y a l l d i s c i p l i n e s .

In business and i n the t r a i n i n g i n s t i t u t i o n s . A large proportion of

the businesses surveyed were involved i n e l e c t r o n i c s . The t r a i n i n g

i n s t i t u t i o n s surveyed did not make e l e c t r o n i c s d r a f t i n g a major

part of t h e i r curriculum.

2. Large dedicated or mainframe CAD systems can be more d i f f i c u l t to

operate than personal computer based systems. Personal computer

based systems were generally considered simple or easy to use.

3. The i n d i v i d u a l s presently operating CAD systems were usually

regular draftspersons retrained f or CAD.

4. Employers would prefer to h i r e draftspersons with CAD s k i l l s .

5. CAD t r a i n i n g i n s t i t u t i o n s prefer to t r a i n draftspersons or people

with some background i n d r a f t i n g or design.

6. Most CAD operators had taught themselves or received t r a i n i n g

through a CAD system vendor or through in-house t r a i n i n g .

7. Employers would prefer that CAD t r a i n i n g be l e f t to appropriate

CHAPTER FIVE

SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS

The purpose of t h i s study was to survey representative businesses

using computer aided d r a f t i n g technology and to survey i n s t i t u t i o n s o f f e r i n g

t r a i n i n g i n computer aided d r a f t i n g i n order to assess the impact of t h i s

technology on secondary school curriculum. A closed-form s t y l e questionnaire

was sent to s i x t y - f i v e businesses and f i f t e e n i n s t i t u t i o n s involved with CAD

and the returned data tabulated and presented i n bar graph format to f a c i l ­

i t a t e e asier i n t e r p r e t a t i o n of the r e s u l t s . The questionnaire was designed

to a s c e r t a i n the t r a i n i n g and background of CAD personnel, the type of CAD

equipment i n use, the areas of dr a f t i n g using CAD, the t r a i n i n g and h i r i n g

preferences of business, the importance of various s k i l l s , and the areas of

secondary school curriculum to be changed or emphasized to r e f l e c t the

technology. The survey instrument was tested and revised before being

d i s t r i b u t e d to the survey p a r t i c i p a n t s .

The review of the l i t e r a t u r e was divided into three areas. The f i r s t

area reviewed the ph i l o s o p h i c a l background to curriculum development.

Educators were urged to keep curriculum up-to-date on the basis that

curriculum content should r e f l e c t the needs of the society that i t serves.

A broad base of knowledge and s k i l l s was considered more important than

s p e c i a l i z a t i o n because of the r a p i d l y changing requirements of technology

and the r e s u l t i n g obsolesence of s p e c i a l i z e d s k i l l s .

The second area of review was concerned with r e l a t e d research i n

I n d u s t r i a l Education. A r e l a t i v e l y small number of studies have been done

Page 66: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

that are concerned with c u r r i c u l a r revision, i n I n d u s t r i a l Education. Most

of these u t i l i z e a survey of l o c a l industry to asc e r t a i n the status or

needs of present curriculum. Survey studies i n d r a f t i n g curriculum

development were mainly concerned with the impact of the changing technology

of d r a f t i n g , but not at the secondary l e v e l . The review established the

survey questionnaire as the predominant method of i d e n t i f y i n g c u r r i c u l a r

development items i n I n d u s t r i a l Education.

P e r i o d i c a l l i t e r a t u r e indicated a need for appropriate t r a i n i n g i n

computer aided d r a f t i n g f i e l d s and mentioned a number of successful programs.

The survey of businesses i n B r i t i s h Columbia u t i l i z i n g CAD required the

compilation of a CAD dir e c t o r y as no published compilation could be found.

This d i r e c t o r y as well as one for CAD t r a i n i n g i n s t i t u t i o n s i n B r i t i s h

Columbia i s included as an appendix to t h i s study.

The survey generated an 82% response rate from industry and a 60%

response from t r a i n i n g i n s t i t u t i o n s . A number of returned questionnaires

from business could not be used as the respondents did not yet have a CAD

system i n operation. Removing these businesses from the sample generates

a 75% response rate. 1

The survey was sent, together with a covering l e t t e r and stamped

return envelope on A p r i l 10, 1985. Non-respondents were sent another

questionnaire, together with a cover l e t t e r and stamped return envelope

on May 10, 1985. Questionnaires received a f t e r June 10, 1985 were not

included i n the survey.

Conclusions:

The survey indicated that businesses i n a wide v a r i e t y of endeavours

are using computer aided d r a f t i n g systems and that they are r e t r a i n i n g

t h e i r present d r a f t i n g and professional personnel to operate the systems.

They do i n d i c a t e , however, that they would prefer to h i r e i n d i v i d u a l s ,

predominantly draftspersons, with computer aided d r a f t i n g s k i l l s should they

require CAD operators. Training i n s t i t u t i o n s are o f f e r i n g computer aided

d r a f t i n g courses with emphasis on t r a d i t i o n a l areas of d r a f t i n g and prefer

to teach i n d i v i d u a l s with good background i n manual d r a f t i n g or r e l a t e d areas.

Manual d r a f t i n g s k i l l s and good problem solving a b i l i t i e s were i d e n t i f i e d i n

both surveys as the major prer e q u i s i t e s f or CAD success. Selected B r i t i s h

Columbia secondary school d r a f t i n g curriculum items were rated and both

surveys placed more importance on dimensioning to CSA standards and viewing

objects three dimensionally than on other areas. C u r r i c u l a r change to r e f l e c t

the changing technology was deemed necessary and included the introduction of

computer aided d r a f t i n g at the secondary l e v e l as well as the i n c l u s i o n of more

dr a f t i n g course time and more emphasis on computational and communication s k i l l s .

Recommendations:

; To the extent that business.interests and post secondary educational//

requirements are i n d i c a t i v e of the need.for.curriculum m o d i f i c a t i o n at the

secondary l e v e l , the r e s u l t s of the survey would support the following

recommendations:

1. That students and educators be counselled to approach d r a f t i n g ,

d r a f t i n g programs to a l l students, not j u s t those i n i n d u s t r i a l

programs.

2. That d r a f t i n g educators i n B r i t i s h Columbia secondary schools should

acquaint themselves with the changing technology of d r a f t i n g .

3. That wherever economically possi b l e , secondary school d r a f t i n g programs

should introduce students to computer aided d r a f t i n g . The choice of

system should r e f l e c t the growing trend i n industry to u t i l i z e

personal computer based systems.

4. That d r a f t i n g educators should maintain contact with post secondary

t r a i n i n g i n s t i t u t i o n s - i n an e f f o r t to standardize secondary d r a f t i n g

curriculum emphasis.

5. That the increased number of course-hours necessary to accommodate the

recommendations of t h i s study could be included i n an i n d u s t r i a l

technology course at the senior secondary l e v e l . This course could

focus on i n d u s t r i a l methods and processes, applicable codes and

standards, and on the development of appropriate mathematics and

communication s k i l l s f o r design.

6. That secondary school d r a f t i n g courses become more involved i n develop­

ing the computational and communication s k i l l s necessary f o r post-

secondary d r a f t i n g programs.

7. That secondary d r a f t i n g courses place more emphasis on the areas of

d r a f t i n g that involve viewing or manipulating an object i n three

dimensions as opposed to the t r a d i t i o n a l orthographic representation.

These would include p i c t o r i a l (isometric/oblique) projections, p a r a l l e l

and r a d i a l l i n e developments, producing views by revolution, perspective

drawing, and freehand sketching.

Page 69: THE IMPACT O COMPUTEF R AIDED DRAFTING TECHNOLOGY …

8. That secondary d r a f t i n g courses place more emphasis on dimensioning

to CSA standards and on following s p e c i f i c codes and standards i n

the preparation of drawings.

9. That the B r i t i s h Columbia secondary school I n d u s t r i a l Education

guide should be amended to include content based on the recommend­

ations of t h i s study.

The review of the l i t e r a t u r e f o r t h i s study indicated a tension e x i s t i n g

between proponents of s p e c i a l i z a t i o n i n education and other more moderate

fa c t i o n s . While there are obvious p o l i t i c a l overtones to t h i s debate (the

in t e r e s t s of the worker and business are seldom the same) t h i s w r i t e r f e e l s

that the adoption of the preceding recommendations would be i n the best

i n t e r e s t s of those concerned and would allow enough f l e x i b i l i t y to keep

d r a f t i n g curriculum current and responsive to change.

Areas f o r Further Study:

The development of t h i s study suggested a number of areas f o r further

i n v e s t i g a t i o n :

1. A survey of i n d i v i d u a l s operating computer aided d r a f t i n g systems

i n order to assess the extent of t h e i r s k i l l s and r e s p o n s i b i l i t i e s .

2. A study to determine the extent to which computer aided production

technology has changed s k i l l requirements and employment demand.

3. A study of the success rate of i n d i v i d u a l s e n r o l l i n g computer

aided d r a f t i n g technology programs i n B r i t i s h Columbia i n r e l a t i o n to

the admission standards of the i n s t i t u t i o n and to the academic

standing of the i n d i v i d u a l .

SELECTED COMMENTS FROM QUESTIONNAIRES

"CAD i s an e l e c t r o n i c " t o o l " used i n the a p p l i c a t i o n of d r a f t i n g . This survey tends to deal with i t by d i s c i p l i n e s or work s p e c i a l i t i e s ( i n d u s t r i a l s k i l l s ) which I believe does not apply. We have upgrade students such as a r c h i t e c t s , engineers, and draftsmen from a l l areas of expertise i n one class taking CAD. Our system has no s p e c i f i c d i d i c a t i o n . "

"I hope t h i s survey w i l l help to somehow organize secondary l e v e l d r a f t i n g programs to prepare students for formal CAD courses. A college CAD consortium should be organized to ensure a consistent l e v e l of t r a i n i n g and q u a l i t y i n the CAD education program. This would also bring together a l l the various programs and equipment fo r a broader ranged CAD survey."

"The survey seems ov e r s i m p l i f i e d i n order to make i t general i n a p p l i c a t i o n . Our motto f or CAD t r a i n i n g , "Teach an engineer to use the computer - you can't teach a computer technician to be a designer."

"Too long."

" F a i l e d to concentrate on organizational and management s k i l l s e s s e n t i a l to CAD e f f i c i e n c y . "

"A useful survey. I think CAD should be kept f o r the college l e v e l with an emphasis on standards and drawing analysis at the secondary l e v e l . "

"CAD systems are ever-changing beasts. The personal "drawing management s k i l l s " which must be developed are extensive. I believe any attempt to teach a student "CAD s k i l l s " would be detrimental to his/her career f o r two main reasons:

1) This time could be better spent acquiring a good te c h n i c a l t r a i n i n g . This i s a much greater asset than knowing the mechanics of producing a drawing.

2) The i n d i v i d u a l w i l l i n e v i t a b l y have"to be retrained to the p a r t i c u l a r o f f i c e ' s CAD standards and procedures."

"Seems to be asking the r i g h t sorts of questions."

"The trend i n computer aided d r a f t i n g i s to s i n g l e independant microprocessor based work stations that are easy to learn and inexpensive. In the near future CAD w i l l replace manual d r a f t i n g , so secondary schools should teach d r a f t i n g on CAD s t a t i o n s . "

"Your system costs are low. A CAD system Is a t o o l not unlike a drawing board; being able to operate a drawing board does not mean you can draw."

"... there are already more CAD draftspersons than CAD systems i n B r i t i s h Columbia. Why t r a i n so many kids f o r such a small job market? CAD systems are p r o h i b i t i v e l y expensive and w i l l continue to be for some time to a l l but the larges t of corporations. In any event, a CAD system that requires extensive t r a i n i n g i s a poorly designed system. What we need are people trained i n the basics of design. Anybody can draw. And even with today's crude CAD systems anybody can draw w e l l with only a few hours t r a i n i n g . TEACH DESIGN."
