I recently conducted another successful workshop on Using games in medical education at the Regina General Hospital and discovered the newly released report Harnessing the power of video games for learning by the Federation of American Scientists. The full report is available at http://fas.org/gamesummit/ Here is an excerpt from their list of recommendations.
Each major educational institution should develop and execute a strategy for changing instruction to reflect the kinds of innovations in games and other areas expected in the coming decade. Schools should redesign their instructional practices and formal learning environments to take advantage of technol;ogy-enabled exploration, interactivity, and collaboration encouraged by digital games and simulations.
To see an example of how gaming might be used in medical education take a look at BioInteractive Labs http://www.hhmi.org/biointeractive/vlabs/index.html or Virtual knee surgery http://www.edheads.org/activities/knee/
