Edutopia, the George Lucas Educational Foundation, has a free, downloadable resource for teachers entitled "Top Ten Tips for Teaching with New Media". It is a PDF file.
The document contains some very good tips on applying new technologies and media to classroom education.
Edutopia's website also has a lot of great resources for teachers. You can also join for a small yearly fee and get even more resources and a subscription to the Edutopia magazine.
This is one of the few educational resources that I pay for because I find it very useful and helpful.
