Here is a current article that talks about the different benefits of playing video games.
If you’re interested in the subject I found a great paper from 2005 about Learning Games.
The Academic Advanced Distributed Learning Co-Lab members David Williamson Shaffer, Richard Halverson, Kurt R. Squire, and James P. Gee wrote an amazing paper about how video games may be the future of learning. They discuss how video games can teach us so much more than how to use a gun. They discuss how video games can teach a 14 year old politics, a normal person complex modeling, and help kids with cancer take better care of themselves. To find the paper use this link and scroll down to Joint Papers and find the working paper titled “Before every child is left behind: How epistemic games can solve the coming crisis in education.”
Don’t forget the FAS National Summit on Educational Games Report. The summit brought together more than one hundred experts to examine how to harness the power of video games for learning. This report is widely cited and contains a collection of the reasons in favor of using games and simulations in education as well the issues that need to be addressed if industry and education are to be able to collaborate on learning games.
