The MindShift Guide to Digital Games and Learning started as a series of blog posts written by Jordan Shapiro with support of the Joan Ganz Cooney Center at Sesame Workshop and the Games and Learning Publishing Council.  This guide is a great in-depth look into current educational gaming research, how to start using digital games for learning, how to choose a learning game, ways to overcome the obstacles for using games in the classroom and finally, how teachers are actually using games.
