I will soon begin working on a somewhat similar problem involving personalized self education. So far I've thought of it as a search engine for YouTube which allows a user to lookup something like "home improvement" and then builds them a "course" comprised of the most relevant YouTube education videos that they can follow along with. There would be an element of self curation and social media (voting and reviews of courses).

Anyway, good luck with your project it is very interesting and I'm sure you'll learn a lot!
