So it's the secondary version of the 'traffic lights', or 'sunshine and rain cloud', or whatever other act of ridiculous public shaming (primary) schools come up with - got it!
I'll be honest, I'm not sure what the answer is to the behaviour issues in school, especially in secondary schools, but it sure as anything it's humiliation. As a previous poster said, it's the antithesis of trauma-informed practice, and when you've had a reason to really look for trauma-informed schools, you'd appreciate how necessary that practice is.
I'm not okaying unacceptable behaviour - not at all, I'm a former teacher, I absolutely understand how soul destroying it can be to be spending half your day managing behaviour rather than actually educating - but public humiliation is not the answer.
Shifting the shit-show of the education system as an institution (not at individual teacher level) onto individuals has had a massive impact on pupils in general - with everything being target driven, teachers need to cram more in to each lesson, so there isn't the opportunity to build relationships to mitigate poor behaviour before it starts. Because for a lot of children - and teens especially, although they'd never admit it - having those relationships with teachers/staff makes them more inclined to behave appropriately, rather than a standard 'screw you' to anyone in authority.
