It?s probably not unusual for junior professors to hear they should devote their time to research rather than waste it on teaching. What may be more uncommon is for one of them to do the opposite. But that?s precisely what Teresa C. Balser did, and her students aren?t the only ones reaping the benefits. Today she is among four faculty members selected as U.S. Professors of the Year, an annual award handed out by the Council for Advancement and Support of Education and the Carnegie Foundation for the Advancement of Teaching. Balser?s determination illustrates a common theme among the four award-winners: a continual, active effort to learn themselves as they promote student learning.
