4
WG 2 2. UNIFYING CONCEPTS MATH COGNIT CONTENTS PROCESSES DIDACT. A) PROCESSESB) CONTENTS C) COGNIT.

5
WG 2 A) PROCESSES vs/PRODUCTS CONTENTS asACTIVITIES &CREATIVITY

6
WG 2 B) CONTENTS: Which? How much? Functions (linearity) Algebraic thought

7
WG 2 C) FLEXIBLE PATTERNS THROUGH OPEN PROBLEMS SISTEMATICITY ?

8
WG 2 3. LANGUAGE INNER PROCESSES LOGICAL SKILLS COMMUNIC. READING & WRITING

9
COMMUNICATION It is related with: processes culture Pupils express themselves Helps students to set down their working into a framework Differences between pupils/teacher/book WG 2

10
4. TECHNOLOGY + DIFFICULT PROBLEMS LOGICAL SKILLS - NUMERACY ? FINAL EXAMS (paper&pencil) DGS: 3D INTUITION/PROOF GIRLS ISSUES CALCULATORS

11
WG 2 HOW TO DEVELOP IT ? DEFINITIONS: ideological features cultural issues 5. CREATIVITY

12
WG 2 6. TESTING OPEN ENDED VS/ STRUCTURED PRODUCTS VS/ PROCESSES

13
WG 2 7. SOME CONTRADICTORY ISSUES CHALLENGING THE INNOVATION CHALLENGING THE TRADITION ? BUT !

14
WG 2 CHALLENGING THE INNOVATION OPEN ENDED MATHS - problem solving with open, non routine problems (no systematic learning; teaching obsolescence) INTEGRATED LEARNING (basic skills in a more or less traditional way)

15
WG 2 CHALLENGING THE TRADITION Challenging the stability of mathematical thinking development in students Examples: hierarchies vs/ networks (van Hiele hierarchy for geom. Concepts) results got by pupils in some specific objective tests seem to contradict their general performances

16
WG 2 BUT IN CHILE, JAPAN,… SOME OF THE CHALLENGED INNOVATIVE ISSUES ARE AT THE BASIS OF THE NEW REFORMS OF THE SCHOOL

17
WG 2 8. WHAT DO THEY MEAN THESE WAR WINDS THAT ARE NOW BLOWING?

18
WG 2 There are elements which are difficult to construct in a constructivist approach to theoretical knowledge and difficult to mediate through a traditional approach.

19
WG 2 9. THE ISSUE OF GEOMETRY USEFULNESS FOR 3D A BASIC PATH IN SOME COUNTRIES (but numerical skill are overemphasized in others) A CULTURAL ISSUE: GIRLS

20
WG SOME DATA: # STUDENTS: FOR EACH CLASS # HOURS PER WEEK:
