摘要

背景在医学院的早期课程中学习超声有助于学生理解解剖学和病理学,并执行明确的超声标准视图。教学视频是一种潜在的有价值的工具,可以提高学习超声技术的过程。本研究的目的是调查学生在准备客观结构化临床检查(OSCE)时,与其他学习机会相比,如何将教学视频视为学习辅助工具。材料与方法在维也纳医科大学第四年制作并实施了11个简明超声视频。视频演示了预定义的检查过程、图像优化和九种标准化超声视图。视频可用于实际超声检查的准备,这是客观结构化临床检查的一部分。使用在线问卷调查学生对教学视频和其他学习方法的看法。结果640名学生中有445名(占队列的69.5%)使用了教学视频。其中134人(30%)回答了问卷。在这个群体中,88.9%的人认为教学视频非常有帮助(49.6%的人认为非常有帮助)。方差分析显示,不同学习材料在帮助性方面存在显著差异。事后分析表明,教学视频被认为是仅次于“自我执行和反馈”的第二有用的学习材料。研究表明,学生经常使用教学视频,并将其视为有效学习的额外工具。

Student Perceptions of Instructional Ultrasound Videos as Preparation for a Practical Assessment
Abstract Background Learning ultrasound early in the medical school curriculum helps students to understand anatomy and pathology and to perform defined ultrasound standard views. Instructional videos are a potentially valuable tool for improving the process of learning ultrasound skills. It was the aim of the present study to investigate how students perceived instructional videos as a learning aid, compared to other learning opportunities, in preparation for an Objective Structured Clinical Examination (OSCE). Materials and Methods Eleven concise ultrasound videos were created and implemented in the 4th year at the Medical University of Vienna. The videos illustrate the predefined examination process, image optimization, and nine standardized ultrasound views. The videos were available to be used in preparation for the practical ultrasound examination, which was part of the objective structured clinical examination. The students’ perceptions of the instructional videos and other learning methods were surveyed using an online questionnaire. Results In total, 445 of 640 students (69.5% of the cohort) used the instructional videos. Of those students, 134 (30%) answered the questionnaire. Of this group, 88.9% rated the instructional videos as very helpful (49.6% as extremely helpful). An ANOVA revealed a significant difference between various learning materials in terms of helpfulness. Post hoc analysis showed that instructional videos were perceived as the second most helpful learning material after “self-execution and feedback.” Conclusion The study revealed that students use instructional videos frequently and appreciate them as an extra tool for effective studying.
