Medical education instructional videos are more popular and easier to create than ever before. Standard quality measures for this medium do not exist, leaving educators, learners, and content creators unable to assess these videos.
Drawing from the literature on video quality and popularity, reusable learning objects, and multimedia and curriculum development principles, we developed a 26-item instructional video quality checklist (IVQC), to capture aspects of educational design (six items), source reliability (four items), multimedia principle adherence (10 items), and accessibility (six items). Two raters applied IVQC to 206 videos from five producers across topics from two organ systems (cardiology and pulmonology) encompassing four disciplines (anatomy, physiology, pathology, and pharmacology).
Inter-rater reliability was strong. According to two-rater means, eight multimedia items were present in over 80% of videos. A minority of videos included learning objectives (46%), alternative language translations (41%), when the video was updated (40%), analogies (37%), or references (9%). Producer ratings varied significantly ( < .001) across 17 of 26 items. There were no significant differences according to the video topic.
IVQC detected differences in elements of instructional video quality. Future work can apply this instrument to a broader array of videos and in authentic educational settings.
医学教育教学视频比以往任何时候都更受欢迎,也更容易制作。这种媒介没有标准的质量衡量标准,这使得教育者、学习者和内容创作者无法评估这些视频。
借鉴有关视频质量和普及度、可重复使用的学习对象以及多媒体和课程开发原则的文献,我们开发了一个包含 26 个项目的教学视频质量检查表(IVQC),以捕捉教育设计的各个方面(6 个项目)、来源可靠性(4 个项目)、多媒体原则的遵守(10 个项目)和可访问性(6 个项目)。两名评分者将 IVQC 应用于来自五个制作方的 206 个视频,这些视频涵盖了两个器官系统(心脏病学和肺病学)的主题,涉及四个学科(解剖学、生理学、病理学和药理学)。
两位评分者之间的一致性很强。根据两位评分者的平均值,有 8 个多媒体项目出现在超过 80%的视频中。少数视频包括学习目标(46%)、其他语言翻译(41%)、视频更新时间(40%)、类比(37%)或参考文献(9%)。在 26 个项目中的 17 个项目中,制作者评分存在显著差异( <.001)。视频主题之间没有显著差异。
IVQC 检测到教学视频质量要素的差异。未来的研究可以将该工具应用于更广泛的视频,并在真实的教育环境中应用。
