Yesterday I had the pleasure of meeting a teen librarian who keeps Dance Dance Revolution (DDR) set up all the time so she can invoke it as need be. For example, if a teen has overdue books, she will dance-off against the person, and if the teen wins, the librarian will waive the fines.

In addition, when the kids get into squabbles amongst themselves, she tells them to take it to the mat and dance off against each other. It's a great way to channel some of their energy.

Another librarian talked about using DDR for indoor recess at school when the weather is bad.

Lots of great ways to use gaming in positive ways.
