perhaps delaying the mind-warping effects of school for a few extra years really helps.
That leaped out at me as well. Piaget demonstrated that brain development tends to come in spurts that are closely correlated with growth spurts. One of the key ones generally hits in the range 5-7 and gives a sudden improvement in ability to learn concrete mental operations such as the ones involved in reading, writing and arithmetic. By contrast the decades long US trend is towards pushing abstract learning younger…
I asked her about it the other day, and the reason was "kids need time to be kids".
I cannot thank her enough - I never had problems learning throughout my school career, and I was never behind the physical curve either, so did reasonably well in sports as well.
I know it's anecdotal but it's something I'd strongly consider if I had kids as well.
