The data shows improvement until 2019 and then a decline in 2020/2021 coinciding with COVID, lockdowns and inability to attend schools physically.
The global pandemic seems like a much better explanation to the data the article is showing.
I'm shocked! Shocked I tell you!
1) I hadn't heard people making exactly the same argument since I was a kid in the 1970s,
2) I've read even older accounts making identical claims,
3) there was no correlation with covid,
4) western society hadn't had many changes over the last 150 years in the way learning is done. (My grandfather's high school education was very different than mine, as I describe out https://news.ycombinator.com/item?id=25574534 .), and
5) education in the US, except of the children of the rich, has always been intimately connected with politics. If there were a golden era where education wasn't ruined, then it was because of politics.
> "The children now love luxury; they have bad manners, contempt for authority; they show disrespect for elders and love chatter in place of exercise. Children are now tyrants, not the servants of their households. They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize their teachers."
> ~ Socrates
One human constant seems to be thinking that future generations are the worst.
Since the western society does not want to change the way learning is done, the path will lead us downwards.
The only chance as a parent to build a better future for your own child is to fight the system and help the child learn.
The decline in learning is yet another example of politics ruining things that work in the society.
