Résumé
The main question in this article is to evaluate a new type of communication technology, the videoconferencing as a tool for remote training. The usage of two tools of videotraining is observed: the usage of individual computer in "virtual class" and a usage of a "remote class". In the first part, a review of the literature will enable us to present the questions specific to the evaluation of video conferencing use within the framework of a training course. In the perspective of use we may consider two type of founding models: the model based of acceptation and the model base on requirements. The second part describes the methodology and the protocol for the videotraining experiment in a true situation, set up within the framework of a research contract with a large company which enabled us to closely monitor nineteen sessions of videotraining. The third part presents the results in terms of use mostly from the students' point of view and also from teacher opinion.
