If you're not a subscriber to ROBOT Magazine, you might have missed a great article in the latest issue on "Teaching with Robotics" - fortunately, ROBOT Magazine has posted the article (with some extra content) on their website for all to read.
Not only is the article very informative, but it's got a TON of reference links... this article might make a great addition to a proposal to a school (or school board) for funding a robotics program.
Take a look at the article here - if you find it of interest, be sure to send the editor, Tom Atwood, an email and thank him for making the article available to the public for free...
