For the teaching of agile methods in an IT undergraduate course we developed a gamified blended learning course. We created the course with gamification elements such as videos, quizzes, badges, and points in the learning management system Moodle. In this paper, we first share our experiences with distributed practice in this course and how gamification supported our flipped classroom approach. We also briefly present results of a survey study that investigated intrinsic motivation with an earlier version of the course and that revealed mixed results, i.e., an increase of intrinsic motivation for some factors, but not for all factors. The evaluation results and observations motivated a future research agenda aimed at further improving and continuously evaluating the impact of gamification on intrinsic motivation to ultimately promote distributed practice as well as sustained learning combined with fun for the students.
