With the advent of videos capturing lectures, I have seen a slew of objections from worried teachers that think their attendance will suffer if students don’t have to show up to hear them speak. Harvard and MIT have been making waves recently with their new EdX initiative. But I believe Stanford has the smarter model.
I imagine teachers 500 years ago struggled with this same idea when Guttenberg’s press made books so cheap. If teaching is just the transmission of knowledge, then why didn’t everyone just start reading to learn new things? I think it’s because learning is more about the experience than a laundry list of facts that can be recorded (on paper or on the video screen).
