There are a couple of very useful resources for high school computer science teachers that are not as well known as they should be. If you are a high school teacher I strongly recommend them to you. If you know a high school computer science teacher, please, pass these on.
I’ll blog about more resources from time to time but these are, I think, especially good. The MSDN AA program is really wonderful for acquiring software while the community at MainFunction is just loaded with helpful resources and information. Pass it on!
