Academic medicine has been described as a three legged stool:clinical services (patient care), teaching, research.
The teaching can take several different forms. It is unusual for a physician faculty member to be responsible for all the lectures in an entire course, but a physician may be the course director for a course or a segment of a course. For example, in a school that uses an organ system approach, there might be one physician who directs the section and makes the arrangement (with administrative support) for other faculty in that division to give individual lectures. Faculty can also be tapped to be small group leaders in problem based learning (PBL) or to teach physical exam and interview skills and/or to teach small groups at "the bedside", to moderate case discussions of patients being cared for by the team, or to supervise students providing services to patients.
