Thanks Alan for an insightful view on "gaining enlightenment" through game making.
Exposure to a complex thinking environment does not of itself lead to deep thinking or enlightenment. You mention "Zen and the Art of Archery" , a similar argument was put in ON THE COGNITIVE EFFECTS OF LEARNING COMPUTER PROGRAMMING, ROY D. PEA and D. MIDIAN KURLAND 1984 http://scil.stanford.edu/about/staff/bios/PDF/Cog_Effects_Prog where Pea quite successfully argues, I think, that the case for Logo had been used many times before in other domains: "This belief, although new in its application to this domain, is an old idea in a new costume which has been worn often before. In its common extreme form, it is based on an assumption about learning - that spontaneous experience with a powerful symbolic system will have beneficial cognitive consequences, especially for higher order cognitive skills. Similar arguments have been offered in centuries past for mathematics, logic, writing systems, and Latin"
What this analysis overlooks is engagement. The levels of achievement are quite astounding for kids who are offered a relevant and authentic challenge and the right tools. Then the "powerful symbolic system" does have "beneficial cognitive consequences" . Maybe not the enlightenment that we would hope for but at least an understanding of mathematics, logic, kinematics, also social skills, affective benefits "I like school" and metacognitive or self regulatory benefits.
I think it essential that etoys is at least as motivating as Game Maker and at least as easy at the entry level. I think there is a lot to learn from teachers like Bill who have a long track record of successfully using such tools and getting exceptional results from them.
