Made up example would be math teacher assigning two hours a day of exercises and worksheets on simple equations, while other teachers already moved on and successfully teach "difficult" equations.
Made up over the top example would be teacher that checks your notebook every other day whether it is nice, organized and colored. He would assign three hours of work of cutting and pasting and coloring and what not every day and make you rework historical diorama five times.
However, that teacher could still miss that you have no idea what happened during historical period he is teaching and do not remember single name or date.
And also where they prohibit them from outside interactions and tightly monitor their social lives (or lack thereof).
Hardly seems permissive to me.
