Graduate students frequently get the chance to meet one-on-one with their professors. Yet at the undergraduate level, especially during the first year, students rarely get that chance, unless they take the initiative to come to office hours or schedule a meeting.
This is unfortunate. I teach first-year writing, and at least once every semester, I meet one-on-one with each of my students, usually to review a draft of their first paper. My students love these conferences, partly because they offer a chance for personal contact with their instructor, and partly because the conferences provide them with uniquely meaningful feedback.
