Khan Academy is one of those technologies that can really disrupt the future of education and not just higher education.
I am really impressed with the work of the Kahn Academy. How does education remain competitive and sustainable when you can use youtube videos to educate. A global classroom using online education is an interesting concept for sure. For higher education, I think it is going to be harder for universities to continue to justify such large tuitions, when learning is no longer completely housed at the university.
And for K-12 education, I think that this video shows some very interesting assessment techniques. Think about how focused teachers can be if they can “zone in” on those students that are not connecting specifically with a lesson or topic and then using peer to peer educational techniques to teach students that material is fascinating.
