Abstract: Objective To explore the effects and feedback of applying augmented reality (AR) technology to case-based learning (CBL) in the clinical teaching of cardiovascular surgery.Methods Twenty doctoral students majoring in cardiovascular surgery in the class of 2022 and 2023 at Beijing Anzhen Hospital, Capital Medical University, were enrolled in this study, respectively. The two grades were divided into the experimental group and the control group with 10 people each by a random number table. The experimental group adopted AR+CBL combined teaching method, while the control group adopted traditional teaching methods. Students in the class of 2022 and 2023 undertook 1 and 2 semesters of teaching-research activities, respectively, and attended basically the same course. The overall scores, output text analysis, and classroom participation of the two groups of students were compared. Additionally, an anonymous questionnaire survey was conducted to collect the two groups' evaluations of the teaching effect, as well as their satisfaction with teachers and their preferences for teaching methods. Results The overall performance of the experimental group was better than that of the control group. Among them, the final scores of the experimental group and the control group were [(84.57±2.26 points) vs. (81.02±2.37 points), P<0.001, Cohen's d=1.53]. The effective interaction frequency of the experimental group was higher than that of the control group, and the questionnaire survey showcased that the experimental group was superior to the control group in terms of clear and understandable teaching methods, enhancing learning interest, shortening learning time, helping to memorize theories and master clinical skills (P<0.05). Meanwhile, teachers had higher satisfaction with AR+CBL combined teaching method and were more inclined to this teaching method.Conclusion The application of AR+CBL combined teaching method in cardiovascular surgery has achieved favorable teaching effects, improved students' learning enthusiasm and clinical practice ability, and is worthy of promotion in clinical teaching.
