Effets d'un dispositif d'aide à la résolution de problèmes géométriques: un exemple avec les programmes de construction
Résumé
Working with a small group of pupils on a problem-solving task before it is presented to the whole class is not a common way of dealing with mathematical difficulties. We conducted an experiment in a French primary school in order to study the impact of a small group intervention on the student’s learning, and on their topos i.e. their capacity to play the role as any other student during the whole class lesson. We have observed positive effects on both, under certain conditions.
