A new culture called Second Life [TM] has emerged that promises innovative strategies for everything from social interactions to business. Some educators believe it may hold new and unique opportunities for teaching and learning. Second Life [TM] (SL) is the creation of Linden Labs, a San Francisco-based corporation defined by its creators as "an online society within a 3-D virtual world entirely built and owned by its residents, where they can explore, build, socialize and participate in their own economy." Over 100 colleges, universities and other learning institutions have established environments with instructional activities in SL. SL provides social interaction that simulates traditional classroom. The author discusses the features of SL and how it works. He suggests that as schools begin staking out territory, defining policy guidelines and conducting instructional activities, educators need to establish a framework that embraces theory and applies effective methods to SL.
