The next set of problems and exercises would constitute a challenge that each person could approach at his or her own tempo; there would be no shame or stigma in progressing slowly, no dreaded moment when the class must move on. The archive of videos would never go away; students could review and refresh as often as necessary. And mistakes would be allowed! There’d be no fear of disappointing a teacher who is looking over one’s shoulder, of appearing dumb in front of a roomful of peers.
