This is a link to Martin Carlisle's home page. Martin has done some interesting work, backed by research studies, demonstrating improvement in learning outcomes when students are asked to watch short focused videos before class and then the class focusses on having the students do things in class. The in class work is then reviewed and, during the next class, good examples (The Gallery of Glory) and "bad" examples (The Isle of Infamy) are shown to and discussed with the students. Examples of Martin's videos can be found at http://www.youtube.com/user/carlislemc.
