Please do, because this is unsustainable. I understand not invoking issues. OTOH unfair to ask teachers to do this if they are unsupported with 24+ children in their classroom.
Actually, I'll talk about it here. I just watched the video in your OP and it really shows the problem.
I watched those parents who stood up and said that "The PBIS you're using isn't working," and who are dismayed that the school isn't changing what it is doing, since what it is doing is clearly a failure.
There's a reason for that. The school district isn't doing what it thinks its best, it is following all the applicable regulations, and court cases. Those don't change, so they keep doing the same thing. They are not insane, so they don't think they can do the same thing and have different results. By now, they know exactly what the results will be, but they do it anyway.
Why do they keep doing what doesn't work, you ask? Because of the lawyers.
In my area, we have an organization called "GCASE," Gulf Coast Administrators of Special Education. Every year, our district leadership invites the campus Sped Department Chairs to attend a conference at the Galleria, Houston's posh business venue.
Do they tell us the latest research in how to teach children with disabilities, and how to prevent children with disabilities from disrupting the educations of their non-disabled peers? Nope. Not a single educator speaks, unless they also happen to be a lawyer. Every speaker is a lawyer except the head of GCASE, who MC's and introduces the lawyers.
We hear about cases in which districts were successfully sued for things like taking a violent kid out of general education, you know, due to their violence. The district gets sued, that kid goes right back to having "access to their peers," and another reason is established of principals to fear common sense.
"Access to their peers," is the legal terminology. The irony that it is those peers they have been beating up that the courts are forcing districts to provide them "access to" is lost on the legal system.
Districts fear lawsuits, and Office of Civil Rights complaints. "Compliance" is always a hotter topic than education. Our leadership when they do tell us about methods of teaching often use research that is outdated by a decade or more, but that was the last time they really cared about kids learning better.
It's a systemic problem in special ed. Special Ed teachers with common sense typically leave the profession in an average of five years. I honestly think it is only because certain aspects of our personalities over-ride common sense that Mrs. Flops and I have stuck with it for twenty years.
In my training in special ed, I was not taught how to educate special needs kids, I was taught to advocate for them. In that mentality, taking a kid out of class because his emotional disturbance makes him a danger to his classmates and teacher is exactly the same morally as taking out all the black kids.
I admire parent for speaking out, but the administrators are not listening to them if what they say does not fit in with their goal of avoiding lawsuits. Those parent have to start suing themselves, every time a kid who is not mentally or emotionally ready for the gen ed class becomes violent and harms someone, but also if their kids are losing their educations due to the disruptions.
A poster above talked about controlling 44 students in Geometry class. I'm sure he's telling the truth. Those higher level math kids are not likely to be emotionally unstable, and certainly not have learning disabilities. I can controls uch student and successfully teach them in small groups.
The problem arrises when those disabled student are pushed in with non-disabled peers in a class full of average, lightly interested, students. Teacher focus on controlling behavior, so there is far less learning.
Those Asian countries that are kicking our asses in standardized testing in Math and Science, are not letting disabled kids take education from typical students, I am sure of that.
