I really enjoy watching TED TV, I think it's a great resource and educational tool. The idea of having an App called TED Ed, where students can learn about something, then build quizzes and test each other on their learning, sounds like a wonderful idea to me. Putting students in pairs or groups and them learning and picking things that they think would be important out of an educational could be very beneficial to them. It can be used with a variety of subject and help students zone in on specific ideas, themes, etc. Putting the assessment in their hands gives the learning another layer.
I found this app on Larry Ferrlazzo's website found here: http://larryferlazzo.edublogs.org/2012/07/10/the-best-web-2-0-applications-for-education-in-2012-%E2%80%94-so-far/
