Specificity of the knowledge in logic and its consequences on Klein's double discontinuity
Spécificités des connaissances en logique et conséquence sur la double discontinuité de Klein
Résumé
In mathematics, logic is a field with a specific and transversal status. Indeed, it allows us to describe, control and validate mathematical activity. Therefore, it seems relevant to teach it in mathematics' classes. First, we present some research results from the DEMIPS' 1 « Logic and Proof » group. Based on interviews with university teachers, we will show different choices made for these kinds of courses and the different epistemologies relating to the proof that underlie them. Furthermore, since 2009, logic is faintly coming back in the french high school curriculum. Then, how can pre-service teachers rely on their university knowledges and transpose them to teach at high school level? We are going to answer this question of Klein's second discontinuity by presenting results from research in mathematics education about students' difficulties and by explaining training situations we suggest.
