in my 40+ years of observing NZ and Aus educational models, the Unions are either incompetent or impotent..wizard of Tauranga while I’ve cut only a few phrases from your well thought out post the comment re the Union is misinformation.
The Union if I understand them correctly are not against change but are arguing that they can’t do what is required of them if they’re under resourced.
If you are teaching a class of 30+ how do you have the time to spend time on those who are struggling to pick things up.
I would be interested to know whether there is any correlation between increasing class sizes and falling learning rates
