Language Learning and Teaching with the aid of Technology
I would like to draw your attention to this page on our SLExperiments wiki, where we have been collecting resources related to language education in Second Life and other virtual worlds. Most interesting for you might be the books, articles and research papers: http://slexperiments.pbworks.com/SL-Educational-Links
The latest addition is a book which looks very useful for teachers starting out in Second Life. This is available as a free e-book but a print version can also be requested here. It is not about language teaching but most of what it says applies to any kind of teaching in SL:
Best Practices in Virtual Worlds Teaching - A guide to using problem-based learning in Second Life http://previewpsych.org/BPD2.0.pdf
Thanks to Anna Begonina for tweeting the link to the book!
