TED

http://www.ted.com/

TED is a great website to learn the basics of a subject and it has a variety of subjects that are discussed with varying levels of details. TED-Ed is an educational oriented branch from the original TED site. TED-Ed allows teachers to create videos themselves which can be watched anywhere their students have access to the site. Also by allowing anyone to create videos teachers can use other teachers presentations which may be exactly the same lesson with a different perspective. TED is made for people in higher levels of education and TED-Ed seems to be for a younger audience. The variety of topics and the easy navigation on the site make TED an effective learning tool.
