Attention to the teleinteractive processes aiming at professional development is an area that currently awakens a considerable interest. Nevertheless, the analysis of the various teachers’ meanings collaboratively shared in a given virtual community is still incipient in the field of educational research. In this paper we analyse qualitatively electronic discourse in virtual seminars and present contributions of distance interactions for teachers’ education. The discussion forum as a communicative space presents and develops important discursive singularities among all the communicating agents involved in the process of professional development.
