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)
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

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.
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
