I volunteered in an infant school for two years 2011-13 two days a week. I was a dad of 3 grown up boys.
I want to present an overview if i may.
Reading out loud was either banned or limited, it helps reading but it also helps speech, better vocabulary helps you to understand the teacher. There's probably millions who don't learn from reading.
I went on a parenting course but they didn't talk about fun.
I witnessed teachers shouting, screaming, belittling and humiliating.
My mum and dad beat me, called me thick, idiot, shouted, screamed etc. School also canned me, hit, shouted, screamed etc.
So many disadvantaged kids were taught that this is discipline but it's not, it's bullying.
I did bully type parenting (copied from school) and my wife did blind love, we were both wrong on discipline but it was no good going to school and asking the head because she bullied the teachers and the teachers bullied the children.
I left school at 15 with a reading age of a 6 year old, reading out loud at 38 helped my temper disappeared. (glue ear/deafness misdiagnosed)
I helped in the school at 56, had fun, made the kids laugh but when i frowned they knew to behave or that's it I'm off to another table.
It's impossible for teachers to do it all but they misled on reading and discipline so I guess just build bigger referral units.
One more thing.....when school says it is at the heart of the community, nothing could be further from the truth.
Oh sorry something else.....i did learn from some teachers, keep calm, be consistent, laugh and they must stand firm when dealing with a head that bully's.
