How can virtual worlds like Second Life enhance the teaching and learning experiences for students?

Places like Second life can enhance the learning experince of both teachers and students by offering them a place where they can let loose, travel, and have fun and at the same time be playing in a game like atmosphere.

Being able to show students virtual models of famous or even old palces no longer around in the real world give a much more complete experience for the students instead of just pictures or a video.

Issues come when students are messing around, become rude due to the fact they feel it's an online world and won't effect their real life world. So there is a fine line that still needs to be defined beofre the full measure of what Second life can so can be seen by stuents and teahcers alike.
