That sounds awful! How old was that kid? If a teacher has to discipline a kid in any way, the whole class shouldn't be involved. I get that students need to face the consequences of poor behavior, but that's just too far. Just write the kid up, give a detention, or call the office or their parents (if you're given their number).
If I may
reluctantly play devil's advocate, the best reasoning that I can give for that kind of punishment is to motivate the kid to not behave that way again. I was learning about different legal theories a while back in my only semester of law school before leaving, and I remember reading about
Deterrent Punishment Theory: making the criminal and the public aware of the punishment in order to deter them from committing a crime.
However, what the teacher in your scenario did wasn't aligned with
Retributive Punishment Theory: the punishment must be
deserved and proportional to the crime committed and any caused harm.
It's a very fascinating subject. Here are some others:
- Rehabilitative Punishment Theory - Punishment/incarceration can serve as a means to address the underlying issues and motivations to rehabilitate offenders into law-abiding citizens.
- Preventive Punishment Theory - Removing offenders from society can prevent further harm if they decide to repeat offenses.
- Expiatory Punishment Theory - It's the offender's moral responsibility to take ownership of their actions, so the punishment can serve as a means of atonement.
- Utilitarian Punishment Theory - Reducing crime and encouraging social order increases the overall well-being of society.
These theories are not mutually exclusive.
