Announcing a new way to use video to create customized lessons: “Flip This Lesson” from TED-Ed. 
With this feature, educators can use, tweak, or completely redo any video lesson featured on TED-Ed, or create lessons from scratch based on a TEDTalk or any video from YouTube. How? Just plug the video in and start writing questions, comments, even quizzes — then save the lesson as a private link and share with your students. 
The site allows you to see who’s completed the lessons and track individual progress.  Read more about it here, and watch a demo:http://blog.ted.com/2012/04/25/flip-it-a-new-way-to-teach-with-video-from-ted-ed/
