Get what you're saying and apologies for not reading through the full thread.
Obviously as well my kids are grown up now so the curriculum has really changed. I am not totally out of touch though as I still childmind school aged kids and I also had a brief return to my first career (speech and language therapy) in 2014.
So i am aware of the WHO report into the crisis in children's language skills and the alarming numbers of children presenting in P1 not ready to take off with learning at all.
And - obviously the Curriculum For Excrement (as known) is woeful and had retarded educational attainment in Scotland.
School readiness 20 years ago - well to be independent in self care skills, dressing, doing fastenings themselves appropriate to age (zips, buttons, velcro)
Knife and fork was a 5yr old skill
All pre reading language skills should have been in place.
These were:
Thorough knowledge of nursery rhymes. Rhyming precedes reading.
Thorough knowledge of pre school songs and ability to clap a rhythm.
Early pen hold and drawing. Ability to draw a person recognisable with facial features and clothing should be there at 5.
Early word recognition - write their own name, know their own birthday, know where they live etc. Recognise common words (Tesco etc!)
(Obvs many much further on but this would have been bare minimum)
Play skills - sharing well developed by 5 and pretend play sophisticated. Ability to create extended play scene and interact with others, turn taking, game rules etc.
Ability to listen, take instruction, follow a simple 3 step instruction. Follow rules.
So - most kids 20 years ago were just ready to "take off" with reading and writing.
Compare that to today - i see in my minded kids those who cannot zip their own coat at 5. Knife and fork - well, that's out the window now even amongst young adults!
Many kids have delayed speech and language at school entry and that means they cannot take off with reading. Reading is key to curriculum and success in education but many kids just do not have pre school foundations nailed by 5.
Of course there are more ASN kids in mainstream than ever before - some are agressive and those that aren't are way behind with play skills.
The 5yr old of 20 and 30 yrs ago is not the same 5 yr old of today.
I personally have not seen 5yr olds in nappies but i have seen the media.
In days gone by the traditional playgroup start age was 2yrs 10 months for a very good reason. Developmentally, a child aged 2;10 would be fully toilet trained, ready to seperate from parent, be ready to engage in early play with other children and enjoy singing, rhyming and all those pre school craft activities.
