BACKGROUND: Previous studies have primarily implemented problem-based learning (PBL) or flipped classroom (FC) teaching models in different majors; however, research on the combined PBL-FC teaching method in clinical medicine is scarce. Therefore, we investigated the combined PBL-FC teaching method in teaching ocular trauma on students' competencies. METHOD: About 75 ophthalmology postgraduates were randomly divided into PBL-FC and traditional teaching groups. Students completed pre-and post-class theoretical examinations, skills evaluation, learning ability scales, and feedback questionnaires. RESULTS: Both groups showed significantly higher theoretical scores and improved learning ability. Feedback questionnaire scores of the PBL-FC group's postgraduates without clinical experience were significantly higher than the traditional group's for some items; there was no difference between groups in postgraduates with clinical experience. PBL-FC group's pre-class preparation time was significantly longer than the traditional group's, but the post-class review time was significantly shorter. PBL-FC group's post-class theoretical performance was significantly higher than the traditional group's. There was no statistical difference between the groups regarding skill operation. Among postgraduates without clinical experience, the PBL-FC group's skill operation performance was significantly higher than the traditional group's; for postgraduates with clinical experience, the traditional group's skill operation performance was significantly higher than the PBL-FC group's. CONCLUSIONS: PBL-FC teaching is better for students without clinical experience or knowledge of ophthalmic diseases. Meanwhile, traditional teaching is a good choice for students with clinical experience who need more relevant knowledge.
