TY - JOUR TI - À la recherche de raisons d’être pour les structures de groupe : quelques praxéologies pour la profession de professeur AU - Bourgade, Jean-Pierre T2 - Recherches En Didactique Des Mathématiques AB - The realization of types of tasks such as “finding rationales for the mathematics to be taught” is often difficult, if not impossible for the profession, due to missing adapted and reliable techniques. In this work, we present an exploration of this type of tasks and give some elements of a possible technique to perform it. This technique is grounded on the study of reports produced in investigation workshops. We chose such resources in order to limit the risk of artificial, “didactical”, raisons d’être, as often found with more usual resources. The technique is based on a twofold exploitation of these reports: a first primordial movement, where the mathematical works encountered in the process of investigation are explored; a second interventionist movement, when the exploration of reports is directed by a given teaching project. As an illustration, we look for raisons d’être for the study of algebraic structures in post-secondary teaching.
