Video games are increasingly recognized as a compelling platform for instruction that could be leveraged to teach students at scale. Hint systems that provide personalized feedback to students in real time are a central component of many effective interactive learning environments, however little is known about how hints impact player behavior and motivation in educational games. In this work, we study the effectiveness of hints by comparing four designs based on successful hint systems in intelligent tutoring systems and commercial games. We present results from a study of 50,000 students showing that all four hint systems negatively impacted performance compared to a baseline condition with no hints. These results suggest that traditional hint systems may not translate well into the educational game environment, highlighting the importance of studying student behavior to understand the impact of new interactive learning technologies.
