Describing Ultrasound Skills Teaching by Near-Peer and Faculty Tutors Using Cognitive Apprenticeship

Phenomenon: Ultrasound skills are becoming increasingly important in clinical practice but are resource-intensive to teach. Near-peer tutors often alleviate faculty teaching burden, but little is known about what teaching methods near-peer and faculty tutors use. Using the lens of cognitive apprenticeship, this study describes how much time faculty and near-peer tutors spend on different teaching methods during abdominal ultrasound skills training. Approach: Sixteen near-peer and 16 faculty tutors were videotaped during one 55-min practical ultrasound lesson with randomly assigned students. Videos were directly coded using Cognitive Apprenticeship teaching methods and activities. Segment durations were summed up and compared quantitatively. Findings: All 32 tutors spent most of the time on observing and helping students (Coaching, Median 29:14 minutes), followed by asking open and stimulating questions (Articulation, 12:04 minutes and demonstrating and giving explanations (Modeling, 04:50 minutes). Overall, distributions of teaching methods used were similar between faculty and near-peer tutors. However, faculty tutors spent more time on helping students manually, whereas near-peer tutors spent more time on exploring students' learning gaps and establishing a safe learning climate. Cognitive Apprenticeship was well suited as observational framework to describe ultrasound skills. Insights: Ultrasound train-the-tutor programs should particularly focus on coaching and articulation. Near-peers' similar use of teaching methods adds to the evidence that supports the use of near-peer teaching in ultrasound skills education.

Automated summary

This study examines the teaching methods used by faculty and near-peer tutors during abdominal ultrasound skills training. The results show that both groups spent the most time on observing and helping students, followed by asking questions and demonstrating explanations. Faculty tutors spent more time manually helping students, while near-peer tutors focused on exploring students' learning gaps and establishing a safe learning environment. The findings suggest that training programs for ultrasound tutors should emphasize coaching and articulation. The use of near-peer teaching in ultrasound skills education is supported by the similar teaching methods utilized by both faculty and near-peer tutors.
