Teaching assistants: perceived academic influence on performance in municipal medical residency exams

Abstract

Introduction: medical students could benefit from teaching university courses. However, there is no evidence showing that this activity improves academic performance on standardized tests in graduate school. The objective of this study was to describe the differences in scores on the municipal medical residency exam between physicians who were teaching assistants and those who weren’t, and to evaluate the self-perception of the effect of being a teaching assistant on the performance on this exam and on academic skills in general.

Methods: this is an observational, descriptive, cross-sectional study, with a convenience sample of physicians participating in the 2018 municipal medical residency exam of the Autonomous City of Buenos Aires (CABA) based on official lists. Those who could not be contacted, refused to participate, or whose identity diverged from the person selected to include in the study, were excluded.

Results: of the 3,579 physicians who participated in the basic municipal medical residency exam in CABA 2018, a random sample of 300 subjects was taken, of which 87 were contacted. Of those, 20 subjects met the exclusion criteria, having 67 subjects finally participating in the study. The proportion of subjects who could be contacted through social networks was 77%. The exam score among physicians who were teaching assistants was 32.3 ± 5.7 points while among the non-teaching assistants it was 29.5 ± 6.1 points. Among the teaching assistants, 68% perceived that the fact of having been a teaching assistant as an undergraduate had a slight to very positive effect on their performance in the exam, 76% referred the deepening of their specific knowledge on the subject they taught, 73% reported an improvement in their communication skills, and 59% referred a greater ability to rank content.

Conclusions: undergraduate teaching would be perceived as an activity that promotes communication skills and ability to rank content and, therefore, as a positive influence on academic performance in the municipal medical residency exam. These conclusions need to be confirmed with future studies.
