Peruse the Open Education Consortium
MIT ... probably too expensive and too elite right?
Well, they realize that and now they are bringing their college lectures to the masses to make up for it. On the Open Education Consortium you can gain free and open access to education and knowledge. In their words:
"Students can get additional information, viewpoints and materials to help them succeed. Workers can learn something that will help them on the job. Faculty can exchange material and draw on resources from all around the world. Researchers can share data and develop new networks. Teachers can find new ways to help students learn. People can connect with others they wouldn’t otherwise meet to share information and ideas."
Contributing universities include: CUNY, Johns Hopkins, MIT, Tufts, University of Michigan, etc.
