KNOWLEDGE & CURRICULUM

Page 3: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 3

Knowledge & Curriculum

• A technical curriculum must address each component of knowledge: Conceptual Operational Integral

Page 4: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 4

Conceptual Knowledge

• Basic facts and observations

“Heavy” objects fall faster than “light”

objects

• Physical laws and principles

Force Acceleration

• Diagrams and schematics

• Mathematical representation

Operational Knowledge

• Formulation and Analysis Conceptual Requirements? Constraints? Initial conditions? Symmetries?

• Methods and Strategies Analytical (closed-form or approximate?) Computational

• Skills and Resources Computing Group dynamics Library Internet

BMA 6

Integral Knowledge

• Conceptual + Operational = Integral Synthesis enables design Practicum provides opportunity to build and test

• Integral knowledge is essential for design The foundation of new technology

• Unique to the engineering profession Given the why and how—what?

A Proactive Philosophy

Instruction and learning begin with teacher and student preparation. The classroom is not the place for teachers to display how much they knowit is the place to learn what students do not know so those things become known.

Page 9: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 9

Teacher Motivation

• Faculty are motivated…

…to minimize load, maximize quality

…by a tangible reward structure

…by professional respect

…by student respect

…by self respect

Page 10: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 10

Student Motivation

• Many students...

…are not motivated to do what is good for them

• reading in preparation for lectures

• homework

• early exam preparation

…are motivated to avoid negative consequences, particularly if the consequences are immediate

• low grades

• negative peer pressure

Page 11: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 11

Teacher Preparation

• Pick the appropriate text Criticizing the text is a waste of time

• Know the text and know your stuff Prepare to ad-lib (oxymoron?)

• Definite, but flexible, plan Syllabus contract Learning goals instead of material coverage

Page 12: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 12

Student Preparation

• You are responsible for your learning Being Smart is not Enough* Reading is fundamental—not intended for homework excerpts

• Work outside the proverbial box Don’t be constrained by “coverage” Why are there references at the end of the chapter?

*D. Dilaura

Page 13: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 13

Teachers in the Classroom

• Learn last names

• Ms. & Mr. for “friendly” formality

• Emphasize good character, integrity, and ethical behavior

• Discuss engineers’ social responsibilities

• Require attendance

• Respect students (those that deserve it)

Page 14: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 14

Students in the Classroom

• Respect your teacher (we deserve it)

• Bring necessities, e.g., book, calculator, pencil, good attitude...

• Respect your classmates

• Respect property

Page 15: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 15

Sensors & Tools

• Unit Quiz Preparation is serious because it counts

Gives immediate feedback (get ‘em while they’re hot)

Outlines the “lecture” by promoting discussion

Helps teacher prepare to ad-lib

Keep it simple, but fundamental

Conventional lecture still appropriate

Page 16: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 16

Sensors & Tools

• Group exercises Integral knowledge through synthesis Group dynamics Exciting and contemporaneous Professional identity Reduces grading

• Biweekly Exams Test individual mastery Discourage “cramming”

Page 17: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 17

Sensors & Tools

• Homework Minor portion of course grade

• Question of the day Reconnects the math-science-engineering disconnect

• Class log and e-mail updates Summary of the day’s activities Reflection and hindsight Complete account of course activities Complements class website

Page 18: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 18

A Proactive Classroom

• Preparation reduced, satisfaction increased

• Classroom is energized

• Students appreciate your effort and, more importantly, their effort

• Students more responsible and responsive

• Students display greater depth of knowledge

BMA 20

Need for Reform

• Emphasis on basic science, mathematics, and engineering science in the early cold-war years 1945-65

• Renewed hands-on, product design focus

• A good engineer… must strike a balance between knowing and doing*

*Seely, B. E., “The Other Re-engineering of Engineering Education, 1900-1965,” Journal of Engineering Education, 88 (3), Jul. 1999, pp. 285-294.

BMA 21

Traditional EngineeringEducation Model*

• Students enter discipline tracks and proceed through distincts steps to graduation

• Little interaction with other disciplines

• Little interaction between graduate and undergraduate programs

• Little interaction with industry or K-12

Page 22: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 22

Integrated Teaching and LearningLaboratory Model

• Create interdisciplinary learning through team projects

• Building as a laboratory

• Learning by exploring

HORIZONTAL INTEGRATION

Page 23: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 23

Discovery LearningCenter Model

• Create industry partnerships

• Do first-class research

• Expose all students to research

• Promote inreach and outreach opportunities

• Create knew knowledge

VERTICAL INTEGRATION

Upper Division Courses

• To maximize multidisciplinary opportunities, no professional electives required to be AES courses

• All junior AES courses include a laboratory component

• Capstone Senior Projects is a year-long synthesis and practicum course with design, build, and test requirement

• Senior Projects sequence is focus of proposed vertical curriculum integration

Page 31: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 31

Challenges and Compromises

• Team teaching A rewarding new paradigm for AES

• Assessment Graduate surveys, student review team Spreadsheet tool for mapping assignments according to desired

outcomes and learning goals, and conventional grade assignment Diligence

• Resources and Facilities Unilateral reform at a state university ITLL space limitations and laboratory expendibles Increased TA need—quantity and quality External funding

Page 32: PROACTIVE TEACHING AND LEARNING IN THE AEROSPACE ENGINEERING CURRICULUM 2000

BMA 32

Conclusions and Future Initiatives

• Opportunity to employ a proactive teaching and learning philosophy

• Increased student-faculty contact hours

• Curriculum lauded by academic peers, industry, advisory boards, and students

• Improved national ranking

• Vertical integration based on the Senior Projects courses

• Discovery Learning Initiative
