Here is a very interest short film about teaching and understanding. It is in the context of Universitys but can be applied to most other learning contexts. This film is being shared freely on the Internet and can be accessed at http://www.daimi.au.dk/~brabrand/short-film/
I think the message in the presentation is great and well presented. We talk a lot about these ideas with instructors but this film really illustrates what we need to do to help students learn more effectively. Please post your comments on how you found the film.
