We all have a second life online

Secondlife did surprise me with its 3D virtual world and the communicative methods. I believe one of the original aims of SL is for education which cost 815billion dollars. According to the introduction video, the educational objectives of SL are as following: to explain pedagogical relevance of SL; to overview the educational locations in SL; to show use of educational tools in SL; and to explore use of learning archetypes in SL.
There are sth. we cannot achieve in the real life, or I should say sth. we cannot take full advantage of. Such as, role playing, like you can choose a real role with prepared actor's lines and well-made scenes as well as costumes in Shakespeare's plays. Another example, the tutorials, like you can visit the Ohio University SL campus, which is attractive to those who want to experience the university life.
But what students show their enthusiasm in SL should be the virtual world. Once they are attracted in it, they will naturally learn how to communicate with others, collaborate with others. They need to build up their social network, and to find resources and information. That is how they will be learning from practice.
It is a pity that till now I can't play freely in SL, but I look forward to gaining more from it.
