More and more classrooms are using Second Life as an educational tool. Some online classes are carried out completely in this virtual world. However, it can be difficult to envision Second Life if you've never logged on.

A new post from The Wired Campus includes a video that shows Second Life in action on MIT's virtual island. Here's a blurb from the article:

Ever since Linden Lab, a San Francisco-based company, unveiled Second Life in 2003, professors and college students have flocked to it. Professors use Second Life to hold distance-education classes, saying that communication among students actually gets livelier when they assume digital personae. Anthropologists and sociologists see the virtual world as a laboratory for studying Human behavior. University architects use it as a canvas on which to explore design. Business professors see it as a testing ground for budding entrepreneurs.
