Scott Schamp is teaching at UGA using Second Life. This is from his blog.

But last Friday, I found myself saying things I never thought I would have to say. “Please don’t sit on the fountain during class. Don’t forget that everyone needs to wear clothes the next time we meet. And, please, try and remember not to fly during class time.”
I Can’t Believe I Just Said That!

Its funny. Years ago, some enterprising faculty members latched onto email for use in conducting class without an actual classroom. Then the web sites become the new online classroom platform. Gee, if that had not happened, then I would have a different career.

Schamp has thoughts along the same lines for use of the web.

SL is a place for minds. It is going to take a while to figure out how we should use it. Frankly, now virtual worlds seem like a powerful creative solution. We just need to find the right problems for virtual worlds to solve. Back in 1994 I felt the same way about the web. It is going to take a lot of patient experimentation to find the best way to harness its potential.

Maybe it will take less than 5 years to see where this technology will take us.
