Education Portal has put together a series of videos on Organizational Change that seem like a nice addition especially for online or part time courses. Education Portal Academy offers these videos for free. The content is fairly basic but some of it might be very useful to augment other course materials. This could help you cover these topics outside of class if you want to do an experiential exercise in class (see, for example, the org change ruse on this site) or if you want to give students some additional background resources.
