<p>I would rather have someone who is experienced in his or her area , with little background in coursework geared toward the classroom, than the reverse.
My oldest daughter attended a private prep school as did Gates and some of her best teachers did not have an undergrad or a graduate teaching degree.
Perhaps the tenured profs may be disappointed that students prefer someone without a string of letters after their name, but a string of letters does not make a good instructor.
My younger daughter had teachers who had been teaching for 20 years ( “and never changed a thing” they said with pride) does that make them more valuable in the classroom?
My mother also has told stories of profs who should have been emeritus years ago, but they shuffled to the classroom long past their ability to discern that it wasn’t 1920 any longer.</p>
