I just came across these great articles by Sean Fears, which offer some practical advice for teaching with the NXT---as well as other interesting science topics.
Every time I come across a new "gem" like these, I wonder what else I'm missing. Do you know of a helpful web resource that might be getting lost on the web? If you do, how about contributing that knowledge to our NXT Resource Collection in the forums?
