Étude des conditions d'efficacité d'une analogie mécanique instrumentée pour l'enseignement de l'électrocinétique en terminale scientifique

Abstract : For over thirty years, research in didactics of physics have shown in many countries that students encounter learning difficulties in electricity and that, regardless of the grade level. These difficulties can be especially explained by a number of misconceptions that prevent the understanding of electrical phenomena. To overcome these difficulties, researchers in didactics and teachers use analogies which are more or less adapted and powerful. To achieve our research, we study an innovative mechanical analogy between mechanical domain (source domain) and electrical domain (target domain). This analogy has the feature of being instrumented, which allows to experiment in the source domain. Our research focusses on the conditions of effectiveness of this analogy for student learning. The literature review in physics, science education, ergonomics and embodied cognition allowed, firstly, to establish a set of conditions to be met by the analogy to be effective. Our work has shown that this analogy has the necessary criteria to be considered an effective analogy. Secondly, we tested the impact of the implementation of this analogy with scientific 12th grade students. For this, we made tests and interviews with students. The test results show a lower efficiency than suggested by the study of the potential of the analogy. Through interviews with teachers and course records, we note a great disparity of use of the analogy. The study of collected data allows to better understand the reasons of the low use of the analogy. These results allowed to design a first version of a manual for teachers.
