Khan Academy (Kahn Acadamy, 2013) is an informal online learning platform that is adding game elements that participants encounter as they move through curricula. This “gamification”, includes the addition of badges, accomplishment statistics and skill tree visualizations that reflect the completion of different learning task and participation in the online community. In this paper we outline the types of gamification used in Khan academy and reflect on their effectiveness in relation to learning theory and motivation theory.
