Alocal university is considering changes to its class structure in an effort to increase professor productivity. the old schedule had each professor teaching 5 classes per week, with each class meeting an hour per day on monday, wednesday, and friday. each class contained 20 students. the new schedule has each professor teaching only 3 classes, but each class meets daily for an hour. new classes contain 50 students.(a) calculate the labor productivity for the initial situation (students/) calculate the labor productivity for the schedule change (students/) are there any ethical considerations that should be accounted for? (d) suppose that each teacher also is required to have 2 hours of office hours each day he/she taught class. is the schedule change a productivity increase?
