The aim of this study was to develop a store service operations practice course based on simulation-based training of video clip instruction. The action research of problem-solving strategies employed for teaching are by simulated store operations. The counter operations course unit used as an example, this study developed 4 weeks of subunits for the course, which includes digital learning-assisted instruction through a video clip of simulation-based training to enhance students' understanding of counter operations practice. Finally, solutions for the problems encountered during the 4 weeks of teaching are proposed, and suggestions based on reflection about teaching methods are provided.
