Traditionally, paper cases are used as 'triggers' to stimulate learning in problem-based learning (PBL). However, video may be a better medium because it preserves the original language, encourages the active extraction of information, avoids depersonalization of patients and allows direct observation of clinical consultations. In short, it exposes the students to the complexity of actual clinical problems.
The study aims to find out whether students and facilitators who are accustomed to paper cases would prefer video triggers or paper cases and the reasons for their preference.
After students and facilitators had completed a video PBL tutorial, their responses were measured by a structured questionnaire using a modified Likert scale.
A total of 257 students (92%) and 26 facilitators (100%) responded. The majority of students and facilitators considered that using video triggers could enhance the students' observational powers and clinical reasoning, help them to integrate different information and better understand the cases and motivate them to learn. They found PBL using video triggers more interesting and preferred it to PBL using paper cases.
Video triggers are preferred by both students and facilitators over paper cases in PBL.
传统上，纸质病例被用作基于问题学习（PBL）的“触发因素”来激发学习。然而，视频可能是更好的媒介，因为它保留了原始语言，鼓励主动提取信息，避免患者的非人性化，并允许直接观察临床咨询。简而言之，它使学生接触到实际临床问题的复杂性。
本研究旨在了解习惯使用纸质病例的学生和指导员是否更喜欢视频触发器或纸质病例，以及他们偏好的原因。
在学生和指导员完成了视频 PBL 教程后，使用改良的李克特量表通过结构化问卷测量他们的反应。
共有 257 名学生（92%）和 26 名指导员（100%）做出了回应。大多数学生和指导员认为使用视频触发器可以增强学生的观察能力和临床推理能力，帮助他们整合不同的信息，更好地理解病例，并激发他们的学习动力。他们发现使用视频触发器进行 PBL 比使用纸质病例进行 PBL 更有趣，也更喜欢它。
在 PBL 中，学生和指导员都更喜欢视频触发器而不是纸质病例。
