Years of teaching and coaching online faculty have taught me that the move from face-to-face to online teaching brings both benefits and dangers. One benefit is that the course's center of gravity shifts from the lecture to discussion. Whereas much of a faculty member's time in a face-to-face classroom is devoted to preparing and delivering lectures, that time is now front-loaded into course creation, and the day-to-day work is redistributed to engaging students in discussion and on assignments.
