Hello all -- The "Learning by Doing" approach works well and is considerably enhanced by using the Personal Response System (PRS) installed in a number of our classrooms. I have been doing this in almost every lecture with up to 90 students in a class for the past two semesters and am doing it again this spring. I find it works well and that students buy into it. It takes some planning but it pays off. (And some textbooks -- including mine -- are coming with materials already prepared for this approach.) Would be happy to demo the PRS again someday. BTW, I did a similar thing without the response clickers for some years, but using the clickers makes it much better. Students, and I, get useful feedback on their progress.
