Synchronic tutoring of a community on-line.

The role of tutors has changed over time, depending on models of learning and on the technology available. This article discusses the evolution of the tutor role and presents a new model concerning the tutoring functions in a synchronous virtual community. The definition of a virtual community starts from a theory of communities of learning and takes the features of the virtual environment into account. A project set in order to verify the tutors' features in a synchronous virtual community with an educational aim will be described in detail. The chats on-line are analyzed combining two analysis systems: (a) a category system describing the tutor's on-line functions; and (b) a discourse analysis exploring the dialogical and interactive dimensions of the tutor interventions. Results gathered from this study highlight typical features of tutoring on-line a virtual community. On-line tutorship appears to be a fluid, situated and dynamic process of meaning negotiation. Tutors are able to take over each others' specific roles and students act as tutors to each other.
