The trouble is trainees aren’t trained effectively. You need a solid grounding in how children learn, how to deliver lessons on your subject, also managing behaviour and dealing with all the other teacher duties. I didn’t get a single day on any of that in my teacher training. You are basically thrown in at the deep end which is terrifying and unprofessional.
Have a bank of high quality curricula and lesson plans to support a high quality national curriculum. They do it in other high scoring PISA countries. Why British teachers have to keep reinventing the wheel I’ll never know. That should be a no brainer if you want to reduce teacher workload.
Secondly, kids who can’t behave and access the lesson for whatever reason - behaviour, trauma, development issues etc should be taken out of lessons and given the appropriate nurture or building blocks etc. Give the teacher the opportunity to teach. Leave behaviour management to other people.
Have some decent sanction that can applied against vexatious, entitled, abusive, lazy, feckless and dickhead parents. There should result in some offence such as ‘hindering a child’s right education’ or ‘hindering professionals employed to deliver a right to education.’
Stop the Ofsted judgements. No public reports. Have two yearly inspections with the aim of support and improvement.
Allow far more free play, extra curricula, trips, arts and sports, music and joy. Children should be allowed to have fun at school every day.
Free good quality breakfast and lunch for every child.
