Gaming does not mesh with the prevailing educational model.
That said, I find Jenny‘s posts on the GLS conference sessions to be remarkable, if not fantastic. In 1987 or so, I, as part of a class project, attempted to teach history to a recalcitrant bunch of my classmates with the Avalon Hill board games, Civilization and Conquistador. Aside from their utter lack of interest in learning the rules of the game, the structure of the class conspired against using games for learning: there’s only so much you can fit into the period and still be able to pass the standardized tests, especially when you’re memorizing answers and not learning.
