Virtual Worlds, 3D Online Environments, and Technological Progress - Wikipedia, the free encyclopedia

Virtual world language learning - Wikipedia, the free encyclopedia: "Both, 3D virtual worlds (such as Second Life and Teen Second Life) and 3D virtual environments (such as Hangout.net) can be used for 3D online language learning. Almost all such language learning projects make use of general virtual worlds that are intended for social networking (rather than for language education). However, there are more recent examples of creating virtual worlds specifically for language education."
