I teach 100% online. As I listened to the presentation, I really like the idea of planning time to review the exam. I can think of a couple of ways to do this as part of the class design. I found this presentation very thought provoking and important for course design.
Reviews are always important in a class. I always review with the students each question and correct answers to the questions along with why it is a correct answer. Of course it is not possible to review the final exams.
