Evaluer les représentations des apprenants en sciences : application d'une méthode d'analyse

In the field of science didactics, the constructivist - and socio-constructivist – approach is based on the concept of initial representations. If the concept is studied theoretically, it is more difficult to integrate it concretely in the learning process. An analytical approach in the secondary education level is presented in this article. This concerns the methodology to integrate and to analyze these representations from a didactical point of view and to integrate them from a pedagogical point of view. To illustrate the methodology, the results of a research on energy transfer learning are presented and refer the construction of a wind turbine
