Phenomenon: Teaching is an important part of the tri-partite mission of every medical center. Although teaching often is given lower priority and recognition as opposed to patient care and/or research, this activity for many physicians in academic medicine ranks second to their patient care responsibilities. Medical teacher training has traditionally been aimed at faculty and residents through faculty development initiatives, continuing education for physicians at professional conferences, formalized degree or certificate programs in education, and residents as teachers programs. More recently medical schools have developed medical-students-as-teachers programs, often offered as 4th-year electives, to introduce learners to the theory of teaching and learning with appropriate application in the clinical setting. Data on learner outcomes and students' perceptions and experiences in these programs consist mostly of their satisfaction after completing such a program. In this article we explore 4th-year medical student trainees' experiences and emerging self-concepts as educators during a teaching elective.
