Student Perceptions of Instructional Ultrasound Videos as Preparation for a Practical Assessment
2019
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). 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. 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.” The study revealed that students use instructional videos
frequently and appreciate them as an extra tool for effective studying.
