摘要：Our goal in this article is to present the methodological posture of Research adopted within the
framework of a thesis (Metge, 2002) in information & communication Sciences.
We suggested tracking down the factors which favor, the sharing of information in a
cooperative work and the appearance of a suitable communication.
From a more operational point of view, we were interested in the units of interactions of a
collective within a school and in communication between its members during working sessions.The observation which was carried out, of ethnographic inspiration, is based on the central idea
that each group, each team builds her play with her own rules. To seize the rules of them it is
necessary to observe interior, i.e. it is necessary that the researcher is one of the actors of the
movement and becomes itself one of observed.
Initially, we will present the practical framework and the questions which it caused, in the
second time, we will treat theoretical reference frame under unclaimed finally, the inherent
constraints with the initial choice.
