Daphne Koller is enticing top universities to put their most intriguing courses online for free, not just as a service, but as a way to research how people learn. In the TED video she explains the many advantageous of online education, being one of them to provide equal learning opportunities to everyone around the world.
Mastery learning leads to better results than lecture based classes do, but not as good as individual tutoring. Online education allows personalization and to tutor and evaluate every single student continuously, thousands of them at the same time. Active learning instead of absorbing information passively not only enables faster learning processes, it also can help stimulating creativity and that, at the end, can lead to a wave of innovation.
