If they are, there’s a psychological problem which does need to be addressed certainly, but we can’t allow the existence of psychological abnormalites to be a major guide as to what we do with neurotypical children. Doing so harms the vast majority of neurotypical students, just as surely as completely ignoring the problem where it does exist harms the anomalous child.
Personally I don’t agree with disciplinary matrices and I’ve seen very little sign of them outside the US. Where they exist though, they seem to be a result of a fear of lawsuits in an overly litigous society and they exists in schools and school systems where corporal punishment isn’t used at all. Are they a problem? Yes, I think so – anything that ties teachers hands behind their backs and makes it harder for them to use their own common sense is a problem – but they are not a problem specifically linked to corporal punishment.
