"I often do wonder about the ability of games to teach teach math or other subjects. Really, what are most RPG's but a series of complex algebra problems? Rather than reading a textbook with word problems in it, wouldn't it be more interesting to present them in a loose narrative and be able to actually visualize the puzzles with interactive help? Many K-12 students might find the game medium a little more familiar than a textbook."
Also, although it's not directly related, this gives me a chance to point everyone back at Tony's post from two years ago, the game concept Mathematica.
