I don’t feel “in class” punishment really accomplishes anything FOR you or the student. Effective management procedures are those which prevents in-class disruptions all-together. If the behavior is such that a “punishment” is needed during class time, then it should be a behavior worth referring the student to the office (imo—since the student is there to learn, not repent).
I teach 4th-12th and my procedures are consistent across grade levels, although tweaked a bit. What works wonders is CONSISTENCY. No threats, no warnings, no favorites.
My 1 rule: If you mess up the vibe, you do the time.
I usually don’t have to explain to the kids what it means. But if they break the rule, they do “the time,” which is detention for me. Not normal detention, but sitting in the band hall facing the wall for 30 minutes. No noise, no sleeping, no activity. Just staring at a blank wall. If they sleep, move, etc, I add 5 minutes.
Of course my admin and parents are completely aware of my policy, and after a good bit of detentions right after implementing this, I barely ever have to hand out a band detention now, and class is SMOOTH.
