ONLINE RESOURCES IN MATHEMATICS: TEACHERS' GENESIS OF USE

The long-term objective of our research is to develop the instrumental approach for teachers. A first step, presented in this paper, is to observe stable behaviours of teachers using internet resources in mathematics. We retain the scenarios as indicators of the genesis processes. We propose a scenario taxonomy taken from categories elaborated by computer sciences specialists and complemented to take into account didactical aspects. The descriptions provided by teachers permitted to observe an evolution of their scenarios elaboration’s practices.
