RESUMEN

PURPOSE: This study was designed to elicit medical students' opinions on the characteristics of a good ultrasound tutor. The results should help educators to create an optimal teaching environment and inform tutor training. MATERIALS AND METHODS: The qualitative study recruited 15 participants from a larger mixed-methods study of 64 medical students who underwent a basic course on abdominal ultrasound taught by faculty and near-peer tutors. During semi-structured interviews, they were asked which characteristics make a good ultrasound tutor. We used inductive thematic analysis to identify the most important categories. RESULTS: Medical students identified teaching themes and subthemes relating to teaching skills (e.g., course structure, repetition, vocabulary, feedback, guidance of participants), tutors' attitudes (e.g., atmosphere creation, empathy) and knowledge as the crucial components of being a good ultrasound tutor. CONCLUSIONS: While some of the themes that students identified are generic to medical education, others are specific to ultrasound teaching. Tutors can use our results to assess their own teaching. They should aim to address learning needs, optimise understanding, give adequate feedback, and create a non-threatening atmosphere with empathic interactions. Accounting for the ultrasound-specific setting they should possess the necessary knowledge, provide verbal guidance to their students, and distribute examination time wisely.

RESUMEN

BACKGROUND: Near-peer teaching is increasingly used in medical education, supporting or replacing faculty teaching. It has positive aspects for learners and tutors, some of which are explained by higher social and cognitive congruence between learners and near-peer tutors (NPTs). This study investigates the optimal combination of faculty tutors (FTs) and NPTs in an abdominal ultrasound course. METHODS: Sixty-four third-year medical students underwent a basic ultrasound course, with 75% of lessons taught by NPTs and 25% by FTs. Each of four groups had a different faculty teaching timing. A mixed methods approach used a survey and semi-structured interviews at the course end to elicit learners' preferences, and end-of-course examination scores to look for differences in outcomes. RESULTS: Most learners preferred having faculty teaching in the second half of the course, saying it would be overwhelming to start with FTs. Learners preferred between a quarter and a third of the teaching to be from FTs, with NPTs rated better at teaching basics, and FTs contributing unique, helpful clinical knowledge. There was no significant between-group difference in examination scores. CONCLUSIONS: Medical students preferred most of their teaching to be from NPTs, with some faculty input in the second half of the course.

RESUMEN

Near-Peers First, Physician Tutors Last. Interim Report of a Mixed-Methods Study Exploring Optimal Timing in Undergraduate Ultrasound Teaching Abstract. While many medical undergraduate ultrasound teaching programmes combine teaching from both physician and student ('near-peer') tutors, there has been little research on how these can be optimally combined. In this study, four groups of 16 medical undergraduates each received twelve lessons from student tutors and four lessons from physician tutors as part of their basic ultrasound course. Each group's physician tutor lessons took place in a different quarter of the course timetable. Quantitative and qualitative data were then collected through an online questionnaire, and 15 participants had 1:1 interviews. This interim analysis shows that, when designing combined ultrasound teaching for medical undergraduates, student tutors should be used at the start and physician tutors in the second half of the programme.
