The document discusses the potential educational benefits of multi-user virtual environments (MUVEs) like Second Life. It notes that over 40 UK universities and colleges have a presence in Second Life. Research estimates that around three quarters of UK universities are actively using or developing Second Life. The document then provides examples of how Second Life has been used in educational contexts like visualization, roleplaying, tutorials, simulations, and conferences. It concludes by discussing challenges and directions for further research on using virtual worlds for education.
