If you can get your bands on it, there's a documentary called The Kids We lose. Watch it. Be advised, those with trauma histories, or who have kids in hard places, may not be able to get through it. Try.
This is interesting to sit with and chew on. By the time a bad behavior happens, the cause for it, has already happened, so why are we focused on behaviors? Unsolved problems cause bad behavior. Lagging skills cause unsolved problems. People are challenging, when they have difficulty meeting expectations.
Solve the problems, realistically, collaboratively, proactively and mutually satisfactorily. This is Dr. Ross Greene's model.
I haven't been able to find enough information on PBIS, to make me feel comfortable using it, and I've seen too many teachers cry, and quit teaching, over something to do with it.
What I think it is that bothers me about PBIS, is this. Positive reinforcement works really well, in animals who will never be expected to speak, because species. By far, PR is best for humans, if you're going to use behaviorism, but I wonder if using behaviorism is damaging us.
This is why I like Dr. Greene's CPS, better. It works for the kids in what would be called tier 2 and 3 in PBIS, without doing damage to the kids who aren't developmentally delayed in the domains of flexibility, adaptability, problem solving, frustration tolerance, and emotional regulation.
Restorative Practices, I have less problem with than PBIS. I have more research to do.
Non behaviorist approaches have positive behavioral effects, without focusing on it. Dr. Becky Kennedy said something similar to if people are going to do this, it has to be as clear as behaviorism, or clearer. I'm paraphrasing.
Non behaviorist approaches are new, that it's scary. B.F. Skinner got away with scary stuff too.
