In case anyone is interested, my article on "Computer Science not just for big kids' has been published in the current (November 2009) issue of ISTE's Learning and Leading with Technology periodical. It touches on the value of, and curricular ideas for, exposing upper elementary and middle school kids to 3 aspects of computer science -algorithmic thinking, boolean logic and data structures/databases.
I think it has some useful ideas for high school teachers too.
For those who cannot not get a hold of the article (it happens to be a members-only article online), I have
reprinted it on SmartBean with ISTE's permission -
