This graduate of Harvard Law has written the book on game playing. Kevin Werbach not only wrote For the Win: How Game Thinking Can Revolutionize Your Business but he also teaches about gamification through Coursera; the last time he gave the seminar, thousands attended from around the world. Because I am very interested in how gaming can enhance learning, I have signed up for this course which begins Monday. Are you registered? It's free.
