Outcomes of the gross and developmental anatomy teaching assistant experience

During the first-year Gross and Developmental Anatomy Course at Mayo Medical School, third-year medical students volunteer as teaching assistants (TAs). Their responsibilities include preparing for dissection, instructing students during dissection, writing examination questions, and giving a lecture. To evaluate the academic and professional impact of this experience on former TAs, a survey instrument was developed, and was sent to former TAs from the past 17 years. Seventy-two percent of the surveys were returned. Most respondents (84%) indicated that the TA experience was beneficial during their third-year surgical rotation. Over 60% identified benefits during Neurology, Obstetrics and Gynecology, and Internal Medicine rotations. The majority (62%) indicated they regularly use the knowledge gained from the TA experience. Communication was the most highly ranked area of skill development, with 86% of respondents indicating gains in lecture effectiveness and 97% in one-on-one teaching. Among respondents, 32% entered surgical or radiological fields, roughly paralleling the non-TA medical student population. All respondents indicated that they would repeat the experience and recommend it to other medical students. Although benefits for long-term career development have not yet been established, the Gross and Developmental Anatomy TA experience had perceived short-term benefits with respect to clinical rotations and teaching skill development.
