description

International audience; In this study, we present a teaching situation to work on the modelling process using real data taken in classroom with tablets. The situation allowed us to work on the concept of the quadratic function with a group of 11th grade students and take into account the hypothesis that the qualitative analysis of the phenomenon, the knowledge of the qualitative properties of the families of functions and the meaning of the parameters are crucial elements for the management and control of the modelling process. We observed they are key elements to choose the function used as a model and to check its adequacy throughout the modelling process. Some student's conceptions on height and time were found and analysed.
