Immersive, 3-D environments have offered opportunities for distance participants to share in any number of activities. With the advent of open source environments that are low-cost and that come either pre-configured or easily configured, this instructor has used these environments in class activities including: presentations, discussions, poster sessions, team meetings within a class, and shared activities (such as visiting other islands or testing 3-D building). Using action research the effectiveness of these environments on community building has been studied and published; students have overcome the isolation of discussion-board-driven online environments and been able to form more effective academic and personal relationships within courses.
