I understand your points just fine; I simply disagree.
You say you can’t pause class to install reinforcement practices with every infraction, but I am explaining that this is a far less disruptive option than dismissing the student every time.
You say punishment deters masses from committing crimes—again, I say look up crime rights in highly policed areas. It doesn’t do anything to deter crime and often makes it worse.
The only potential benefit from removal from society/class is the temporary pause in one person’s actions. If that temporary pause ruins one kid’s life because you think it’s too “patronizing” to build a relationship, then that’s on you. Again, there are times it is necessary. But it should be the last and final resort.
I am fine with disagreement, but to call my experience a patronizing suggestion is dismissive and rude. There is great benefit in prioritizing a positive learning environment. It’s not a waste of time. It’s not bullshit. It is how almost every rockstar teacher becomes a rockstar. It’s also how even struggling teachers, like myself a few years ago, can grow to really enjoy their students with whom they once thought would never get along.
You can try and dismiss behavioralism or call relationship building a trope all you want, but they are quantitatively a more productive form of classroom management than suspensions, alternative placements, or office referrals in most cases in pretty much every study from the past 20 years of pedagogy research.
