With their tutorial videos, Khan Academy has made a big splash in the education world. Having Bill Gates singyour praises in a TED Talk is a sure way to get a lot of attention.
Over at Action-Reaction, Frank Noschese has an article Khan Academy: My Final Remarks. I agree with many of his points. Here is a quote from near the end of the post:
Khan Academy is just one tool in a teacher’s arsenal. (If it’s the only tool, that is a HUGE problem.) Khan Academy can be useful for some kids as a vehicle (build skills) to help them get to better places (solving complex problems).
On his Quantum Progress blog, John Burk also chimed in with Project Euler vs Khan Academy: The Future of Online Learning. I agree that Project Euler is really, really good, but that is a topic for another post.
