I understand the last paragraph of Tony's post like this: "wouldn't students be better off watching college lectures on TV, and then go have a discussion with the professor after? Or better yet, don't sign up for college science courses at all!"

To the first question, I would answer with an analogy: wouldn't it be better to watch Yo Yo Ma give a concert on TV (or streaming video), and then meet the virtuoso afterwards to talk about his playing? If you're even thinking about replying yes, you need to get out more.

To the second question I would reply with this observation: the new leadership in science and math is taking root overseas. Not just the leadership, but the critical mass of talent as well. The primary reason is that science and math are sought by students in colleges overseas, while a large percentage of US students have their faces buried in the mashed potatoes. That's an immortal phrase of Linda Ronstadt.
