I second this. For anyone trying to teach computers (and anything else), this will save you from repeating all the mistakes that all the other computer programming education startups are making/will make in the future.

Again, just to be clear, this book is really really really really important.

Hope that landed. :)

Mindstorms? I did a quick google and there are assorted books with that title (after you filer out "lego"). None seemed to be relevant to this discussion.

Who wrote it? What year?

I linked to it at the end of my comment, where I also mentioned who wrote it.

Here it is, again: http://www.amazon.com/Mindstorms-Children-Computers-Powerful...

Lego Mindstorms are named after it.
