As a Harkness teacher, I do believe that students must be asked to struggle with their thoughts, readings, and ideas. They need to engage in thoughtful conversations with peers and teachers in order to hone various ideas. I am not anti-lecture, but I do not think students can acquire historical thinking skills via that map. At times I think it is easy to read a set of notes from the front of the room. We all have been in classes in which the instructor said the same thing that was in the reading. Like a great speech, a good lecture is hard to draft. I found this post interesting.
