This ppt was put together as a request for introducing SL to student-teachers who had never been in SL nor other environments. Consequently, this ppt sticks to the generalities of SL and provides some examples of current Teens' efforts in SL. Slides 9 and 10 came from lyrlobo (see: http://www.slideshare.net/lyrlobo/an-educational-tour-of-second-life)
