Le cadre théorique de l’ETM étendu : Analyse d’une séquence utilisant la relativité restreinte
Résumé
The theoretical frame of the extended MWS allows to analyse the tasks operated during the process of modelling. It allows to show, through the example of a special relativity teaching sequence in a grade 12 class in France, which are the interactions between the cognitive plane and the epistemological planes of the physics or the mathematics. The geneses, the association of geneses and the interaction between differents plans can be clarified for certain stages of the cycle of modelling.
