EDTECH CLEARINGHOUSE: Wow. Got to give it up to the folks down in the Sunshine State. This smorgasbord of a directory put together at the University of South Florida points to online information sources, professional organizations, and lesson plan resources for every grade and every subject, period. Not to mention the tens of thousands of images, pictures, map, and presentation templates available for educational, non-commercial use. Put this in your bookmarks, asap!
