摘要：Learning platforms, such as WEBCT, DOKEOS, MOODLE or any other have now become inevitable virtual arenas in learning environments whether they are at a distance or not. They are constituents of teaching practices, thus form an organizational object, but also of mediation, between various university actors.From an ethnographic methodology we purpose to study the position they presently hold in networks which construct digital teaching as well as to examine the use of these artifacts in universities. Our analysis is based on recordings of synchronous interactions (VOIP telephony) and asynchronous exchanges (forums, emails) between teaching staff and students, as well as recordings of online activities collected altogether as part of a university course in language sciences, at degree to Masters level, in a French university.
