The document discusses gamification in e-learning and what techniques were tested by the College of Policing. It tested five game techniques (avatar, levels, leaderboard, mystery, scaffold) on 500 officers using a randomized control trial with a two minute video clip. The officers provided feedback on their views of the clips and motivations for learning. The clip featuring the mystery technique received the most positive feedback so it was developed into a full e-learning package. The College of Policing is now using gamification and immersive e-learning to engage officers in training.
