If the university is a good vendor, it will instruct this wayward employee to give the customers the convenience they expect.
Alternately, they may back up their employee, agree that different teaching techniques can be useful and that she may have a point about their education being better doing it her way and the level of competency of the graduates will lead them to higher compensation and ultimately to increased business for the school.
