Of the TED talks given last week, this is the one of the ones I was anticipating the most. Human interaction is crucial to learning, but that interaction is just part of it. Can a robot or youtube video do my job? Only if I stand in front of the class the whole time and lecture. Sure, listening is an action, but doing something more interactive like student-student or student-teacher is a much more valuable use of their time. I had a few colleagues come back from the NAIS conference recently and really liked Sal Kahn both as a speaker and what he had to say. It really shifts the paradigm of traditional schooling, but as an educator, it also makes sense in many ways. I still need to explore Kahn Academy’s website and materials more thoroughly, but after this talk, I’m convinced I really need to. Best of all, it’s all free!
