Résumé
The integration of ICT into the teaching and learning of school subjects remains still rather weak, even in highschools. Changes in users' practices required by such integration have probably been underestimated: teachers are obliged to question and change their professional practices. It turns out that standard training sessions towards ICT have been found to be unsuited for supporting teachers in overcoming their difficulties with this integration. This document describes a specific distance, in-service training organization, as well as its implementation and difficulties encountered in the process. A structure of resources has emerged from this collaborative virtual workshop towards the conception of pedagogical resources. Such long-term organizations could turn into efficient supports for teachers using ICT in classrooms.
