I’ve done an extensive research on the educational value of games, both informal and formal, it can be read online at the following link (it was done for the Radboud University Nijmegen and Vereniging van Openbare Bibliotheken which is the overall instution for libraries in the Netherlands)… Hope you find some of your interest in there, it had been very comprehensive, this research, and it got a lot of information about effective educational elements of games… as well as some of the dangers of (too much) gaming… moderation indeed is key to good gaming (21 hours or less, you say). Most is written in Dutch though there are some english and german quotes in it as well, maybe some institution want to pay me to write it in English? If so, contact me at [email protected] (also I’m in for some new research on the topic of gaming and education/reading/art/culture etc.). I’ve graduated as a literature student with game thesis.
