Knowing what you know and don't know focuses learning. Students need appropriate feedback on performance to benefit from courses. First, students need help assessing existing knowledge and competence. In classes, students need frequent opportunities to perform and suggestions for improvement. At various points during their college experience, and at the end, students need chances to reflect on what they have learned, what they still need to know, and how to assess themselves.
Good practice emphasizes time on task.
Time plus energy equals learning. There is no substitute for time on task. Learning to use one's time well is critical for students and professionals alike. Students need help in learning effective time management. Allocating realistic amounts of time means effective learning for students and effective teaching for instructors.
