The rapid advance of AI and ML asks for better and earlier education on these topics. However, research on teaching AI and ML topics is relatively underdeveloped. Especially applying the teaching method gamification has not yet been thoroughly tested. This research aims to explore the effectiveness of gamifying ML education in high schools. An experiment was designed based on previous research. This experiment revolves around a computer game where students learn to train a car to drive itself. Despite small sample size, results show increased motivation and low anxiety.
