Teaching is an interesting kind of partnership.
I think the faculty and the students have mutual responsibilities for each other. Faculty have the responsibility to make sure that what they are offering students is current, well-informed, appropriate for engaging students in the learning process, and appropriate for what students are likely to do. At the same time, students have the responsibility to make sure they have enough time and energy to devote to study, and an open mind for learning. There is no research on learning that shows that a student's time on task is not the biggest predictor of learning. We need to be clear that the partnership works only when each partner is doing their share.
