Most faculty schedule at least three office hours per week—that’s 2,700 minutes a semester. If you have 135 students, that’s 20 minutes for each student. Even if you have 270, that’s still 10 minutes per student. Recently I’ve been working to make the most of these 2,700 minutes of office hours. They offer prime time for one-to-one mentoring. In the process, my thinking about office hours has shifted a bit, and I’m using my office hours in more ways. Consequently I have had a greater number of students taking advantage of this learning opportunity.
