Construction d'un modèle mental au cours d'une activité de résolution de problème : l'application du théorème de Pythagore

Abstract : A mental model is a representation of the surrounding world, created by the human mind, who allows the construction of a certain reality, of mental simulations. These representations can be propositions, images or a group of neurons. The aim of this study was to provide a better understanding of how a mental model is constructed by our mind in a geometrical problem, involving the Pythagoras's theorem. We studied two variables : the type of wording and the typicality of shapes. We wanted to study if having a drawing of the shape with the wording could help for the construction of a correct mental model. Two groups of pupils in troisième (highest class in French high school) were asked to resolve geometrical problems : 11 pupils had wording of exercises with the shape drawing while 12 other pupils just had the wording (just text). The outcome showed a positive effect of the association of drawing with the text to help resolve the problem. The results also showed an effect of typicality of the shapes : problems involving a shape with a strong typicality level were easily resolved. Finally, we showed that a mental model can be saved in episodic memory and help in the construction of an other mental model.
