使用视听工具来辅助医学教育的情况一直在增加。我们的研究旨在发现一个关于“脂肪肝”的视频的功效，这个话题对于临床前教师来说往往是一个挑战，它可以增强认知过程并最终提高学习效果。我们准备了一个11：36分钟的视频演示，结合了主题的各种概念，同时保持在视图迈耶和Ellaway的多媒体演示指南。以录像为干预手段，对100名学生进行了学科知识的前后测研究。一个回顾性的预研究进行了调查，询问学生对主题的关键概念的理解，并对我们的视频进行了反馈。学生在后测试中表现明显更好（平均得分8.52比前测试中的5.45），在回顾性前测试中做出了积极的反应，并对我们的视频演示给出了积极的反馈。正如我们的研究所示，设计良好的多媒体工具可以帮助认知处理和增强工作记忆容量。在“智能”设备普及率高的时代，医学教育中的信息和通信工具可以作为重要的辅助工具，而不是取代传统的教学工具，对学生有益。(C)2015年由国际生物化学和分子生物学联合会，44：241-245，2016年。
Use of audio visual tools to aid in medical education is ever on a rise. Our study intends to find the efficacy of a video prepared on "fatty liver," a topic that is often a challenge for pre-clinical teachers, in enhancing cognitive processing and ultimately learning. We prepared a video presentation of 11: 36 min, incorporating various concepts of the topic, while keeping in view Mayer's and Ellaway guidelines for multimedia presentation. A pre-post test study on subject knowledge was conducted for 100 students with the video shown as intervention. A retrospective pre study was conducted as a survey which inquired about students understanding of the key concepts of the topic and a feedback on our video was taken. Students performed significantly better in the post test (mean score 8.52 vs. 5.45 in pre-test), positively responded in the retrospective pre-test and gave a positive feedback for our video presentation. Well-designed multimedia tools can aid in cognitive processing and enhance working memory capacity as shown in our study. In times when "smart" device penetration is high, information and communication tools in medical education, which can act as essential aid and not as replacement for traditional curriculums, can be beneficial to the students.
