"Our kids are embarking on a Hero's Journey as they compare their own experiences in World of Warcraft to those of Bilbo Baggins in Tolkien's The Hobbit," explains Gillispie. "They're engaging in creative projects as well, such as live tweeting the events leading to Cataclysm from NPC's points-of-view (see #wowinschool hashtag). They're creating digital propaganda posters related to in-world events, writing riddles to share with players on their server, and learning leadership through their student guild."
