[A2A] I tried a couple of times (but failed to maintain my interest), not to improve my teaching but to learn about a subject. But, I am not that patient to listen to these lectures on my computer. I really like attending classes, but live classes where I have an opportunity to ask questions. A class without opportunity for questions is no class at all. So, I don't really like MOOCs despite what people claim them to be. They are not going to revolutionize education. They will bring the quality of education down if we consider them to be on equal footing with regular schools.
