Here's an interesting quote from Kevin Alderman, a pioneering entrepreneur in Second Life, who recently sold one of his popular virtual sites for $50,000 (yes, 50 thousand dollars) to a group of investors:
Static web pages were great for information connectivity. But (in
virtual worlds) you make the paradigm leap away from something that is
projected to you and toward something you create that represents
yourself. You impress your own psyche, motivations, creativity onto a group of pixels and become quite attached to it.
I think we have all had similar experiences not just online, but in many captivating activities in which we invest self. The various forms of telepersona are expanding to be more interactive that ever before: daybooks, scrapbooks, journals, photo collections and other physical methods of self re-creation are being extended even more powerfully into the virtual realm.
I think that is an important psychological clue as to why simulation software is the future of foreign language learning. It is not just the ability to automate in a very sophisticated way the old fashioned drill and repetition, but that with a telepersona involved there is a much higher level of personality and personal involvement.
And that addresses one of the most important factors in adult second language learning: overcoming the social and self inhibitions that impeded the motivation to learn, to get beyond the specific task oriented model of simpler simulations and become open to more sophisticated life like interactions.
BUT, getting virtual environments like Second Life to work for teaching will mean not just using them to replace current practices, but instead to start to build a simulation like pedagogy of practices, such as James Paul Gee advocates.
