Preview and review can double your retention

To be an active student, we have to overcome our spectator training.
Come to class with all homework finished. Sit in front of the room. Pay attention to cues, gestures, boardwork, repetition, emphasis, transitions. Ask questions of yourself, the topic, and the instructor, if possible. Use the 15 minute preview and review solution described below.
