Greatly enjoyed the talk.<p>But, really, taking what he's doing to the limit (he even says so himself) is just re-creating the Socratic method. (Though choosing the questions is hard work, as he notes.)<p>And he can't do that, given his large class sizes (one of my classes at Harvard was 700+ people, Ec 101 with Samuelson from MIT), so he uses this peer-teaching approach to work around the limitation that he can't sit down with a small group of them and work through the questions.<p>That's why we are sending some of our home-educated kids (those that show the interest in and capacity for a rather intense education) to Thomas Aquinas College in Ojai, CA.<p>It's probably the only school in the world that uses 100% Socratic method for all courses (each no larger than 17 people), with no electives all 4 years, outside of St. John's of Annapolis/Santa Fe (on which TAC is modeled to some degree).<p><a href="http://www.thomasaquinas.edu" rel="nofollow">http://www.thomasaquinas.edu</a> for those interested.<p>(Yes, it's an unabashedly Catholic school, but that doesn't diminish the intellectual rigor in the least. It's also in one of the most beautiful spots in the world, in the foothills of the mountains north of LA, near Ojai, which is where the 50's film "Shangri-La" was made and which is still a spa/resort area today.)
