As medical education increasingly incorporates digital methods such as video lectures, e-learning, and virtual meetings, it becomes crucial to evaluate the effectiveness of virtual classrooms in teaching surgical techniques. This study aims to assess whether live virtual classrooms can effectively convey surgical skills to medical students.
First- and second-y medical students were randomized to in-person or live-video sessions once a week, for 2 wk. Students were taught how to perform simple interrupted sutures with instrument-tying. At the end of the workshop, participants were recorded performing simple interrupted sutures. Postinstruction skills videos, blinded to student group placement, were graded from 1 to 5 based on instrument handling, time, efficiency, tissue handling, wound closure, and overall technique.
Out of 114 enrolled students, 42 completed the workshop. Notably, the virtual group had a significantly higher proportion of dropouts than the in-person group. Rubric scores showed no significant differences in various skill categories between the two groups. While both groups acknowledged the helpfulness of their respective methods, a majority expressed a preference for in-person instruction. The postcourse survey revealed that students valued in-person instruction for real-time feedback and multiple-angle demonstrations.
This study demonstrates that video instruction may be equally effective in improving students' surgical technique compared to live sessions. However, it also highlights a clear personal preference among students for in-person instruction, emphasizing the value of a personalized, hands-on approach and enhanced visibility provided by in-person teaching methods.
随着医学教育越来越多地融入视频讲座、电子学习和虚拟会议等数字方法,评估虚拟课堂在外科技术教学中的有效性变得至关重要。本研究旨在评估实时虚拟课堂能否有效地向医学生传授手术技能。
将一年级和二年级医学生随机分为两组,一组每周参加一次面对面课程,另一组每周参加一次实时视频课程,为期2周。教授学生如何使用器械打结进行简单间断缝合。在工作坊结束时,记录参与者进行简单间断缝合的过程。对不显示学生分组情况的课后技能视频,根据器械操作、时间、效率、组织处理、伤口闭合和整体技术从1到5进行评分。
在114名登记入学的学生中,42名完成了工作坊。值得注意的是,虚拟组的辍学率明显高于面对面组。评分标准显示,两组在各项技能类别上没有显著差异。虽然两组都认可各自方法的帮助性,但大多数人表示更喜欢面对面教学。课后调查显示,学生重视面对面教学的实时反馈和多角度演示。
本研究表明,与现场教学相比,视频教学在提高学生手术技术方面可能同样有效。然而,这也凸显了学生对面对面教学的明显个人偏好,强调了个性化、实践操作方法以及面对面教学方法所提供的更高可见性的价值。
