Modélisation de phénomènes variables à l'aide de la géométrie dynamique

http://www.emf2012.unige.ch/index.php/actes-emf-2012International audienceWe present the analysis of a modelling process framed by a didactical engineering. It consists of a series of intermediate models producing a calculable model to solve a problem of two periodic phenomena coincidence. We try to delegate to the students a part of the modelling process. Therefore, with dynamic geometry, we organise a milieu for the validation of the models in reference to the reality
