Professionals in any field love to get together and share information and experiences, and educators are no exception. The Virtual Worlds Best Practices in Education (VWBPE) is holding their annual conference next month (March 18-21). It's free to attend and (of course!) it's being held in Second Life. It can also be accessed from the OpenSim hypergrid.
Caledon Oxbridge University will have a presence at the conference, too. As one of the premiere organizations using virtual worlds to teach about virtual worlds, COU brings a lot of practical experience to the table.
If you're a teacher, either on line or in Real Life, you should mark your calendar and plan to attend!
