摘要: 目的 探讨增强现实(augmented reality,AR)技术联合案例教学法(case-based learning,CBL)在心脏外科临床教学中的应用效果与反馈。方法 以首都医科大学附属北京安贞医院2022级和2023级心血管外科专业博士研究生各20人为研究对象。其中两个年级分别采用随机数表法分为试验组及对照组各10人。试验组采用AR+CBL联合教学法,对照组采用传统教学法。2022级和2023级学生分别进行为期1学期和2学期的教学研究,并采用基本相同的课程设置方案。对比两组学生的总体成绩、产出文本分析、课堂参与度,并通过匿名问卷调查两组学生对教学效果的评价及教师的满意度和授课倾向。结果 试验组的总体成绩各项均优于对照组,其中试验组的总评成绩为(84.57±2.26)分,高于对照组的(81.02±2.37)分,差异有统计学意义(P<0.001)且差异显著(Cohen's d=1.53)。试验组学生的有效互动频次高于对照组,且问卷调查表明试验组在教学方式清晰易懂、提升学习兴趣、缩短学习时间、帮助记忆理论知识和帮助掌握临床技能方面均优于对照组(P<0.05)。同时,教师对于AR+CBL联合教学法满意度更高,且更倾向该教学法。结论 心血管外科教学中应用AR+CBL联合教学法取得良好教学效果,提高学生学习积极性和临床实践能力,值得在心外科临床教学中推广。

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.
