Difficultés d’un système didactique à propos de l’enseignement du volume au primaire

Abstract

Difficulties of a didactic system on teaching volume at primary school. Our work studies didactic systems including the main didactic system, essentially the classroom, and the auxiliary didactic system which is peripheral to the former. Through a case study, this paper deals with the difficulties of the didactic system encountered when setting up an aid session prior to the resolution of a volume problem. This type of aid session having proved worthy in the context of previous research, has led us to study the difficulties encountered during its implementation. Three difficulties emerged from this study: those related to the teaching project, to the choice of didactic material and to the concept of volume itself. These difficulties had consequences, mainly, on the mesogenetic function of the didactic system, but also, systemically, on the other functions.
