The interactions between the teacher and the students are central within face-to-face learning. However little of this interaction is written down and kept for further use. In this paper 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 a wireless classroom, and presents the hardware and software required to implement them. An experiment schedule and the first results are presented in order to study the feasibility and interest of our approach.
