Preservice teachers often need help applying classroom management theories to real-world situations due to their abstract nature. Using a case-based instruction strategy for teaching classroom management topics is a common practice to introduce preservice teachers to the contextual complexity of classrooms. This study investigates and compares the effectiveness of two case-based teaching strategies: face-to-face discussion versus a gamified online case-solving platform. Gamification is an instructional approach incorporating game design elements to enhance learners' motivation and engagement in educational environments. It is aimed at increasing students' interest and involvement in learning activities. The study showed that the gamified online case-solving platform group scored higher on the pre-test, post-test, and student perception surveys. The study examines and discusses the possible reasons for the new method's success and provides potential implications.
