I had read the Quillette article and wondered whether to comment. Then it was featured over at Maggie's and I thought I'd better have a go. My comment over at MF:
"I don't know about specific implementation in schools, but "getting the potential audience out of the way" is a good strategy on a psych ward, particularly with teenagers. People calm down quicker when there's no one to show off for. That's not just theory. Once you get used to implementing it, it works quickly.
It's less-effective but still better than other interventions with the kids who are out-of-control for neurological reasons, who don't have an effective 'off'' switch of their own. More people looking at them puts more energy into their system."
I honestly don't know what is best in schools. It's not my field. I do know that the older forms of discipline work better on kids who are already well-behaved. Of course, pretty much anything works on them. Because most people who are reading about educational practices online and commented on blog sites about them were better behaved and better students than average, their memories of what worked do not generalise as well as they suppose. Also, the special needs children were largely not in public school in my day, and particularly in high school, they dropped out or got expelled pretty early. That removes them from both the discipline samples then, and our memory samples now.
