College teaching is done behind "closed doors". The door closes when the bell rings and the lecture begins, but it is also closed in other respects. It is closed because lecture rooms are somewhat formal. Auditing or visiting permits are required for those not taking the course. Our peers, our administrators, and other students do not feel free to enter, to observe, or to criticize our teaching or its content. It is closed also in the sense that the wisdom embodied in the course is exposed only briefly during the one hour increments of presentation and otherwise is enclosed in the notes and mind of the professor. He opens his door for only one hour per semester or, in the case of low enrollment courses, for only one hour per year.
