The educator who advocates that punishment should be replaced by regression is American psychologist Burroughs Frederic Skinner. Skinner's theory holds that in teaching activities, punishment is replaced by regression. The more times students are reprimanded or punished for not observing classroom discipline, the more frequently they disturb classroom order. They make trouble in class just to get the teacher's attention, but reprimanding or punishing them gives them positive reinforcement. Therefore, we can't use punishment, but ignore the destructive behavior of students, and gradually reduce or even eliminate this behavior by gradually disappearing.
