Titre de la communication :	MODELLING WITH SKETCHPAD IN THE TEACHING OF MATHEMATICS
Résumé de la communication :
Mathematical modelling as the process of finding and validating a mathematical model that explains a phenomenon you want to study with the main purpose of understand it, and apply this understanding in a more general way, is an excellent vehicle for the teaching of mathematics from Upper Middle School (pupils between 15 and 17 years old) to College since it gives meaning to the mathematical content we are teaching, covering the gap between the mathematical knowledge acquired by our students in non school environments and the formal knowledge we want to teach in school. Mathematical modelling also awakes the student interest on branches of human knowledge other than mathematics. Now, the use of Dynamical Geometry software like The Geometer’s Sketchpad (V4.0) puts an additional attraction in the students perspective, an attraction that you can not achieve with others computerized media. The main objective of this lecture is to reflect on the pros and cons of this approach through the development of a modelling activity, and to take into account the potentialities of DG software in the teaching of mathematics while commenting some results the author has gotten with his own students.
