The University of South Florida's Educational Technology Clearinghouse has assembled an easy to use, yet extremely informative site that helps teachers understand technology better.
Everything is covered from the Internet to email, hardware issues, software issues, and even practical ways of implementing more technology into a curriculum.
Help comes in a number of formats as well. There is simple question and answer but also some nifty video and print tutorials.
Tech Ease promises "quick answers to real classroom technology questions" and delivers.
