Abstract

More emphasis is now being placed on active learning in medical education. Ultrasound is an active learning tool that can be used to supplement didactic instruction. This study describes a self‐guided activity for learning floor of mouth ultrasound. Thirty‐three first year medical students learned floor of mouth scan technique and ultrasound anatomy through a brief PowerPoint module. They subsequently performed the scan on a standardized patient. Each student was asked to label the floor of mouth muscles on the image he or she acquired. After the activity, the students were given a quiz on anatomic relationships of the floor of mouth. Perceptions about the activity were collected through a survey. All 33 students obtained a floor of mouth image within a three minute time limit. Twenty‐four (73%) students were able to completely and accurately label the image in time. The mean score on the muscle relationships quiz was 93%. Overall perceptions were very positive with most students expressing a “high” or “very high” level of interest in incorporating similar self‐guided activities within the curriculum. This study showed that it is feasible for students to learn scan technique and recognize relevant ultrasound anatomy in an independent fashion through a brief active learning module. Furthermore, the students found the activity enjoyable. The implication is that similar activities could be developed which would provide additional ways to incorporate active learning strategies.
