Just saw this today (via Invocatio): it is a Latin composition class that is quite creative. Instead of composing boring prose, students learn how to compose magical spells. Moreover, the entire class is based upon role-playing games; so, everyone takes on the identity of an ancient person and works on their Latin through the different developments in the game each week. And when one reaches a new "level" in the game and score points, it affects one's grade.
Perhaps something fun and educational to think about for any language teacher out there; might be interesting to apply to other types of classes, too. Maybe in a Gospels class, everyone takes on a character in Gospel literature, see how that character develops each week in new readings? If someone is, for example, Matthew/Levi, they would, furthermore, learn more in-depthly about ancient tax systems, tax farming, etc.? Just thinking out loud.
