Ed Tech Island 145.218.29 EDTECH island offers free resources and space for all teachers and faculty. Boise State University sponsor the site. You can learn how to build in SL, there is a scavenger hunt to practice moving in SL, you can add characters and role play with students, there is an arcade with games to practice math facts and other things, and a teachers Lounge that has lesson plans and other ideas. There is an amphitheater that you could have a lecture in and also a virtual world. I have not figured out much in the virtual world. I am sure there is a lot more than what I have found. http://slurl.com/secondlife/EdTech/110/129/24
