My plan for education longer term (state ed) is to turn primaries into something similar to private.
Start at 8am, breakfast all together.
Teachers teach until 1pm.
Few breaks, none very long - have you seen the 30 seconds it takes a primary school kid to snarf lunch down?
Teachers then have no-contact time every day until 4pm.
During this time, children do the specialist stuff, taught by specialists.
(Art, music, drama, singing, sports, languages)
Teachers have PPA and do small group interventions or do training.
They have to stay on the school premises.
Everyone finishes at 4pm.
No child takes homework home, they are free for clubs in the early evening.
No teacher takes work home, they can have a life.
After school club can be a thing until 6, but if parents have dropped off at 7.45, then maybe less take up to cover working hours.
It bigs up the arts and sports, taught by people who are actually good at them - which every government allegedly says they are doing. It prepares children for widely for specialism along with their talents/interests at secondary.
Teachers can choose to teach one of the specialism afternoons, so it's not making teaching 'just' core + couple of foundation subjects.
Ta daaaaa...
Not sure how much it would cost compared to current system. When we looked at it in my small primary school (last job), it was sort of do-able. We spoke to a few parents to sound it out and only complaint was 'I like eating breakfast with my children'. I can't think of anyone who REALLY likes eating breakfast with their children!!
