With an exploratory study conducted with more than three hundred science students of a French university (Poitiers), we have investigated the impacts related to the use of a new Internet platform (called IPinfo). This platform have been designed to develop and to improve the cooperation and the collaboration between users : science students, their teachers and several scientific experts. In this paper we described first the architecture and the functionalities of the IPinfo system which comprises several components including management of the relations among users and databases. Second, we present results obtained with our impact study. Thru the use of Likert scale questionnaires, and for two groups of students (with vs. without the use of IPinfo system), we have compared the perceptions of their teaching. We have also assessed the opinion of users group about services offer by the platform (group with only). Results shown that if the global perception of the students on their teaching is not influenced by the use of the platform IPinfo, on the other A? hand, quite expected effects are generated, like distance work for example.
