Abstract. Our research is based on the hypothesis that the most important problem that has to be solved, so as to help tutors, is the gap between required competencies of distance tutoring and the lack of training and recommendations given to them on the role they have to play in the learning process. In this article, we detail the development of the assistance environment for tutors named TE-Cap (Tutoring Experience Capitalization). We first present results of interviews conducted with tutors to define their explicit and implicit needs. We then detail functionalities of the TE-Cap (Tutoring Experience Capitalization) platform we developed and first results of an experiment, in terms of computing functionalities and interface design. Finally, we present some future directions of our research.
