I agree that kerbal should be part of a High School education. I also think that Garry's Mod with WireMod should be part of trigonometry and electronics/programming. I honed my trig by building tracking bots that followed a specified player. Without trig it still would have been possible, but it's so much easier to do it the trig way.

Fun and play should be a part of learning, without them learning becomes a rather dull and boring task of spewing back the memorized rules/formulas without a deep understanding of why or how to use them.
