This research examines computer-supported collaborative learning. Master's of business administration (MBA) students in an online program were surveyed to examine the extent to which an orientation toward teamwork and the development of group cohesiveness affect overall student learning and the learning that results specifically from team interactions (team-source learning). The results indicate that both teamwork orientation and group cohesiveness predict student learning, with group cohesiveness mediating the relationship between teamwork orientation and student learning. Teamwork orientation and group cohesiveness appear to be equally important predictors of team-source learning. The implications of this research for the use of teams in online distance education are discussed. (Contains 3 tables.)
