Résumé
We propose to computerize some pedagogical interactions occurring in class, so that the learner could store all the results of the pedagogical activity. Furthermore, the teacher is able to complement and go through the pedagogical resources for future uses. Our paper studies the contribution of computerized interactions during a class, and presents the hardware and software required to implement them. The devices considered here are a videoprojector, laptops and interactive whiteboard or tablet PC that enables handwriting. Our study is concerned with collaborative work in pedagogical situations.
