Abstract:
In modern medical curricula, embryology is typically taught through lectures, with a few institutions providing tutorials. The use of 3-D videos or animations enables students to study these embryological structures and how they change with time. The aim of this study was to assess the quality of cardiac embryology videos available on YouTube. A systematic literature review regarding the use of YouTube in teaching or learning cardiac embryology identified no papers that examined this specific question, and next, a systematic search of YouTube was performed. A total of 1200 cardiac embryology videos were retrieved using 12 specific search terms, with 370 videos retrieved under two or more search terms and excluded. A further 511 videos were excluded under additional, specific criteria. The remaining 319 videos were evaluated with the YouTube Video Assessment Criteria (UTvAC), with 121 rated as \"useful.\" Videos on YouTube are uploaded with a wide audience in mind, from children to cardiologists, and content control is imperfect. Multiple videos were identified as duplicates of videos from original channels, typically without attribution. While 49 videos showed operations or human material, none contained an ethical statement regarding consent, and only 10 of these included an age restriction or graphical advisory. While there are useful videos for medical students studying cardiac embryology on YouTube, intuitive search strategies will also identify many with irrelevant content and of variable quality. Digital competence and search strategies are not innate skills, so educators should teach students to assess information so as to avoid overload or \"filter failure.\"
摘要:
在现代医学课程中,胚胎学通常是通过讲座教授的,一些机构提供教程。3-D视频或动画的使用使学生能够研究这些胚胎结构以及它们如何随时间变化。这项研究的目的是评估YouTube上提供的心脏胚胎学视频的质量。关于在心脏胚胎学教学或学习中使用YouTube的系统文献综述发现,没有论文研究这个特定问题。接下来,对YouTube进行了系统的搜索。共检索到1200个心脏胚胎学视频,使用12个特定的搜索词,在两个或更多搜索词下检索到370个视频,并排除在外。另有511个视频被排除在其他内容之外,具体标准。根据YouTube视频评估标准(UTvAC)对其余319个视频进行了评估。121人被评为“有用”。\“YouTube上的视频上传的受众广泛,从儿童到心脏病学家,内容控制是不完善的。多个视频被识别为来自原始频道的视频的副本,通常没有归属。虽然有49个视频显示了手术或人体材料,没有一个包含关于同意的道德声明,其中只有10个包括年龄限制或图形咨询。虽然在YouTube上有对医学生学习心脏胚胎学有用的视频,直观的搜索策略也会识别出许多内容不相关且质量可变的人。数字能力和搜索策略不是天生的技能,因此,教育工作者应该教学生评估信息,以避免过载或“过滤器故障”。\"
