Sarah Robbins, a.k.a. Intellagirl, is gearing up to teach her English 104 course online, in the world of Second Life. The Ball State University professor will guide 18 students through the core-curriculum class by encouraging them to explore a virtual island campus, which Robbins designed. But slackers hoping for that easy 'A' will be in for a surprise. "It's probably going to be harder than any other 104," says Robbins, adding, "but it may be more fun."
