Further to my webinar via the Connected PE Online Conference this evening, here are books I have read on Gamification:
Actionable Gamification by Yu-Kai Chou
Gamify Your Classroom by Matthew Farber
The Gamification of Learning and Instruction by Karl M. Kapp
For the Win: How Game Thinking Can Revolutionize Your Business by Kevin Werbach
The best of those is easily Actionable Gamification. While it wasn’t specific to education, it did the best job relating the game mechanics to real world scenarios. Definitely check it out if you want to know more on the topic! His website is pretty fantastic too!
