Learning too use one's time well is critical for students and professionals alike. Allocating realistic amounts of time means effective learning for students and effective teaching for faculty. Good practice communicates high expectations. Expect more and you will get it. Expecting students to perform well becomes a self-fulfilling prophecy.
Good practice respects diverse talents and ways of learning.
Many roads lead to learning. Different students bring different talents and styles to college. Students need opportunities to show their talents and learn in ways that work for them. Then they can be pushed to learn in new ways that do not come so easily. This list was on a handout that I received at a seminar that I attended.
