The same scenario is repeated, except this time the administrator tells the student to stand until he remembers. The student will remember in fewer than five minutes because of the uncertainty of how long he will need to keep standing. The same principle is at work in the high school where the student is stopped in the hallway after the bell has rung. I have one more to go before I get detention. Announcing consequences ahead of time is counterproductive when dealing with young people.
Uncertainty is much more effective.
Knowing the consequence focuses on the consequence. It is better to have students focus and think about what is appropriate. If a consequence is deemed necessary, rather than impose it, a more effective approach is to elicit the consequence from the young person. For example, whenever I was absent from my class, my substitute folder contained a form which requested the substitute to leave the names of those students who acted inappropriately. Upon my return, I would speak to those students who had not been good hosts to the visitor in our classroom.
