Most colleges and universities have resource centers where graduate students and professors can learn more about the craft of teaching. The University of Virginia's Center for Teaching Excellence is dedicated to "committed conversation about teaching at all levels and in all academic disciplines." On the site, visitors can look over seven sections, including Programs, Workshops, Consultations, Publications, and Teaching Tips. This last area is a true gem, as it contains tips organized into themes such as diversity, grading, critical thinking, course development and design, and of course discussion leading. The Occasional Paper Series is worth a visit for meditations on "A Teacher's Attention" and "In the Undergraduate Mind: The First-Year Experience from Three Perspectives."
