User Centred Design in a Learning Environment Based on a Computer Algebra System
Dominique Lenné, Jean-Michel Gélis · 2002
Though they have not been designed for this usage, computer algebra systems are increasingly used in learning situations. In order to improve their didactic capabilities we study the possibility to graft mathematics interactive learning environments onto them. We present in this paper our design approach that relies on Human Computer Interaction methods and integrates mathematics learning knowledge. This approach has been applied to design a learning environment, called Limites, that helps students to study, work out and justify limits of rational functions. We present the main features of this environment, focusing on three points: algebraic expressions manipulation, conjectures and proofs.
