Analysing mathematical and didactic praxeologies in an engineering course: the case of Strength of Materials.
Résumé
This paper provides an overview of the various stages of our research, which seeks to better understand the use of calculus in university engineering courses. We first illustrate the use of integrals in a classic task (sketching a bending moment diagram) in a Strength of Materials course, showing that although integrals appear in the theoretical block, they are not explicitly used in the practical block. Our analysis of the course's reference book shows that this situation is replicated for all notions defined as integrals. This leads us to seek further information by examining teaching practices and by considering mathematical and didactic praxeologies. Our preliminary results indicate that, although integrals are present in the knowledge block of the course, their presence in the practical block and in the evaluation is significantly weaker.
