Résolution de problèmes au cycle 3 : les effets de la multiprésentation

摘要

Problem solving is at the heart of mathematical apprenticeships as it allows to strengthen the sense of the operations and develop an ability for the reasoning. However, a large number of pupils show some reluctance when faced to this activity. Following a finding of recurrent failures in some types of additive problems in the classroom where I work part-time, I decided to set up a specific support scheme: the multiprésentation. This help consists in offering a problem under three different statements but strictly isomorphic: same structure, same numerical values and same final solution. This device is the subject of this thesis, especially with the multiprésentation choice (pupils choose one of the problems on the three offered). The sequence was set up in a CM1 class to verify to what extent the multiprésentation can help pupils visualize the problems. If the results show improved achievement rate after a training over three sessions, it is the motivation of pupils which the most confirmed the usefulness of this aid.
