In this paper the authors will review research on international projects which have used communications technologies, primarily email and web-based video conferencing, to bring learners together across geographic, political, religious and cultural boundaries in the interest of building more cohesive communities in places frequently characterised by conflict and sometimes by violence. The body of research draws mainly on examples based on elementary and secondary schools, primarily in Europe and Israel, so the data do not bear directly on postsecondary education. In presenting this information here, the authors hope to do two things: (1) to make a case that a focus on technology-supported community cohesion has a place in postsecondary education; and (2) to raise questions about how such a focus might be structured and what it might achieve. That is, they hope to focus attention on the lessons that postsecondary educators may learn from the way K-12 schools are using online technologies to promote community cohesion.
