摘要：Learning clinical skills in a large group of undergraduate medical students is challenging. Innovative technology-based modalities are being evaluated to complement limited hospital rotations. We determined the effectiveness of clinical skills-related audiovisual (AV) aids embedded in electronic-problem-based learning (PBL) sessions, in terms of students’ feedback and formative Objective Structured Clinical Examinations (OSCE) grades. This mixed-method study was conducted during the Cardiovascular System module in year 3 of the Bachelor of Medicine, Bachelor of Surgery program. The AV aids, mainly consisting of abnormal chest auscultation sounds, were linked to the cases for the intervention group. The control group received only a description of clinical signs. Sessions were conducted using an intranet platform. At the end of the module, feedback was obtained from intervention group students and faculty using a self-administered questionnaire. The learning was compared between intervention and control groups through an OSCE. Finally, focus group interviews were conducted to explore factors underlying deviation from the expected results. Out of 110 intervention group students, 86 (78%) responded. The students appreciated the inclusion of AV aids, as suggested by a high average satisfaction score of 4.2 (SD 0.8). They agreed that, apart from being appropriate and relevant, the aids improved the learning environment and engagement in the process. The tutors also gave a similar feedback. However, no difference in the OSCE scores was found between control and intervention groups. The study indicates that inclusion of AV aids improved students’ engagement and classroom environment in electronic-PBL sessions, but did not improve diagnostic abilities based on the learned clinical skills.
