An increasing number of educators are using a multiplayer virtual environment called Second Life to promote learning, even to the point of holding classes online within the game world. Now with over 1.3 million members, Second Life has been gaining popularity partly due to its potential for improving distance learning and “introducing international perspectives.” Many different kinds of “virtual classes” have been held within the game, with applications for simulations, new media studies, corporate training, and subject matter ranging from law (e.g. a course by Harvard Law School), business, social sciences and architecture.
Second Life has more information on their Second Life Education Page. In their own words, “Second Life provides an opportunity to use simulation in a safe environment to enhance experiential learning, allowing individuals to practice skills, try new ideas, and learn from their mistakes.”
