Professor Werbach presents a series of lectures that go into real depth about gamification, what it is, the psychology and research behind it, and implications for developers and people interested in the topic. I'm not an online gamer so am not very familiar with basics such as points, badges, leaderboards, and levelling up. Examples of games and gamification are plentiful in the course so it's easy to follow the material. (I became interested in gamification after reading 'Reality is Broken' by Jane McGonigal.)
Professor Werbach is enthusiastic, scholarly but engaging, and has put together a very professional MOOC. He could teach other professors a lot about online learning.
