Enhancing mathematical thinking in Finnish elementary school mathematics- pedagogical models (and modelling)
Dr. Heidi KrzywackiDepartment of Teacher EducationUniversity of Helsinki, Finland
Finland is located by the Arctic Circle…
Finland is in the North Europe, part of the Nordic countries
…and the home of the REAL Santa Claus is in the Finnish Lapland!
Where is Finland?

• the significance of developing mathematical thinking skills... offering opportunities for the development of mathematical thinking and for the learning of mathematical concepts and the most widely used problem-solving methods.The discipline's concrete nature serves as an important aid in bringing together the pupil's experiences and systems of thought with the abstract system of mathematics.
Modelling is hardly mentioned in the curriculum!

Teachers in Finnish elementaryschool
• is typically qualified to teach all 13 school subjects at grades 1 to 6
• has a Master’s level university degree(3+2 years, 300 credit points in total)• majoring in educational sciences / psychology• only 7 cp dedicated to mathematics education
• Teachers are considered as autonomous academic professionals who• choose learning materials and take full responsibility
for teaching and learning in the classroom• design and carry out assessment

Characteristics of Finnish school system (1/2)
• responsibility at the local level: neither school ranking, national exams nor pre-evaluation of learning materials
• Compulsory and intended instruction time of an elementary teacher is 667 lessons per year
NOTE: the number of teaching hours does not reflect explicitly the teachers’ total workload

Characteristics of Finnish school system (2/2)
• Total amount of lesson hours in 9-years comprehensive school is 5,750(cf. OECD average 6,500; max. Italy 8,300)• 32 weekly mathematics lessons
(~ 3.5 lessons per week)
• Schools are of various sizes and rather small in average• About 44% of all schools <100 pupils (12% of all pupils)• About 22% of all schools >300 pupils (54% of all pupils)• Average class size at elementary leve is 19.8 (OECD 21.4)

www.helsinki.fi/yliopisto
Learning mathematics:students have an active roleA child is seen as an active and social learner who is
basically willing and motivated to learn as well as capable for self-regulated process
• thinking at concrete level (Piaget, Galperin)• embodied cognition (tactile and kinestetic approach)• verbalization and oral communication
(also performing initiatives)
• support to building up self-efficacy (Erikson)• positive learning experiences, assessment and
feedback

Learning arithmetic mathematical concepts1. Concrete strategies• Conceptual understanding based on concrete models
and illustration• manipulatives• illustrations and figures• images of the use of the concrete
2. Mental strategies• conceptual understanding and processes without
images of the concrete• One or more steps are embodied in the arithmetic
processes
3. Automatizised conceptual understanding

8 + 5 = 8 + 2 + 3 = 13
127 + 38 = 127 + 30 + 8 = 157 + 8 = 165or = 127 + 3 + 35 = 130 + 35 = 165

A. The use of manipulatives and illustrations
B. Inductive approach to elementaryschool mathematics
C. Word problems and problem solving
www.helsinki.fi/yliopisto
A . The use of manipulatives and illustrations• manipulatives and illustrations play a helpful role in
learning mathematics, especially in enhancing conceptual understanding and also in problem solvinge.g., attribute blocks, geometric shapes of different colours
and sizes; counting cubes, base ten blocks, fraction pieces, number line, surface model etc.
• BUT these are potentially confusing if their presentation is haphazard, disorganized, or lacking appropriate guidance and instruction from the teacher

In teacher education student teachers• acquire knowledge and skills (cognitive potential) to
use manipulatives and illustrations• learn how to make (abstract) and formal mathematics
approachable• get to understand what school mathematics is about
and the meaning of well-structured and meaningful instruction
EXPERIENCE makes a difference!

C. Word problems and problem solving
www.helsinki.fi/yliopisto
• Individual cases as a basis for understanding mathematical rules and facts• investigating phenomena through student work
e.g., commutativeness (a + b = b + a), the sum of angles of a triangle, calculating the area of parallelogram etc.
A teacher needs to guide students to find general notions based on their investigationsstudents’ previous knowledge and skills form a
starting-point for investigations
21
B. Inductive approach to mathematics
Department of Teacher EducationDr. Heidi Krzywacki Modelling Conference, January 10, 2013
www.helsinki.fi/yliopisto
• Previous knowledge about triangles and angles
each student draws a triangle(or a teacher gives triangles of different shapes and size)
setting the aim for investigation

B. Inductive approach:The sum of angles of a triangle
• Examining the triangles: measuring angles and guiding students to make notes about their measurement
listing outcomes of student work and letting students to figure out that
the overall sum of angles is 180°

• Summing up the investigative session and its outcome
the sum of angles of a triangle applies with all triangles but not with other shapes
www.helsinki.fi/yliopisto
In teacher education student teachers• get familiar with inductive approach as a method in
mathematics classroom
discuss which contents can be approached especially through inductive approach and student investigations
a special challenge is to have an impact on student teachers’ views of school mathematics

manipulatives)3. All steps of the solving process4. Finding the solution(s) and reasons behind it
• Making the problem solving process visible support to the process and understandingcommunicating mathematics with othersbecoming aware of personal problem solving
process and reflecting on the process

Altogether 20 witches are to travel to magic mountains by 8 brooms. Each broom can fit 4 witches at the most but each broom must have at least 2 witches. Find out how all witches can travel to the mountain.
Solve the problem above and reflect on the problem solving process and the strategies you used in finding the solution.
NOTE: illustrate and communicate your problem solving process as accurately as possible.

Concluding remarks
34
Department of Teacher EducationDr. Heidi Krzywacki Modelling Conference, January 10, 2013
www.helsinki.fi/yliopisto
1. Reachable aims and differentiation
• Developing activities suitable for different kind of learners• What is(are) the objective(s) of the activity?• Reflecting on how well the chosen tasks worked in
the classroom and how to modify them if needed?
• Assessment procedures should reflect the nature of teaching and learning
Department of Teacher EducationDr. Heidi Krzywacki Modelling Conference, January 10, 2013
www.helsinki.fi/yliopisto
2. Paying attention to affective aspects
• becoming aware of personal strategies and qualities as a mathematics learner
• commucating (sharing) with others verbalization• positive experiences and encouragement
avoiding categorisation in the classroom based on mathematical performance
’everyone can do mathematics’routine tasks are also needed
Department of Teacher EducationDr. Heidi Krzywacki Modelling Conference, January 10, 2013
www.helsinki.fi/yliopisto
3. Approaching mathematics through pupils’ eyes
• Concrete abstract• The contextualisation of mathematical tasks should
be close to children’s everyday life or something they find easy to approach
• Mathematical performance (thinking) is not only performed through correct symbolic expressions• Manipulatives and illustrations• sensitiveness for understanding pupils’ ways of
thinking
Department of Teacher EducationDr. Heidi Krzywacki Modelling Conference, January 10, 2013
www.helsinki.fi/yliopisto
4. Resources and materials supporting school teaching
• Teachers need support in enhancing their practice in mathematics classroom, for example, suitable tasks and pedagogical ideas
learning materials (textbooks and worksheets)teacher guide books (pedagogical support for
teachers)computer-aided teaching and learning
Not only materials but also education that supports teachers (and schools) to enhance their practice
