From Cathy Rape:
I think I understand where that reaction comes from, but I don’t think that’s what is really going on. All the LTW lessons are written in the mimetic form I mentioned above. Each lesson takes one simple idea and demonstrates how to teach it mimetically. It doesn’t make the idea complicated, but it does offer a specific way of teaching each idea that is unfamiliar to most in the beginning. So there are really two things going on in LTW. It’s teaching the teacher to teach in a certain way, and its providing content for the student to learn.
