The Boston Globe has run an article titled: Second Life shows new promise as virtual forum for diabetes education. The article is about the Boston Medical Center training diabetics how to manage their condition via classes in Second Life™.
The Center did a study to see how effective the class was. They assigned half the study participants to a class in SL and the other half to a class at the hospital. Quoting the Globe:
The trial was a hit. Mitchell said the Second Life participants didn’t just sit in on the course sessions. They made friends, swapped recipes, had dance sessions, hung out. Most tellingly, participants wanted to know if they could involve their families in the game too.
The results were both groups progressed at the same rates and improved in equal amounts. But, it was the SL group that evidenced more engagement and learning persistence.
