And here it is: Games and Education
David Millians teaches history in an elementary school in Georgia, and has been known to use RPG and LARP elements in his lessons. To read or hear about them is to wish you'd had the opportunity to roll up a character and join in. (You can hear an interview with David, including some accounts of his classroom adventures, on Sam Chupp's Dragonkin podcast right here
His blog also covers other types of games as educational tools - but of course, the RPG posts will be my favorites. If you are even the slightest bit interested in teaching through RPGs and other games, be sure to subscribe to David's blog.
