What's the longest we can go without streaming and still meet reasonable targets? The people designing this curriculum seem to say they can't get rid of streaming without dramatically lowering the bar.

This means an informed discussion needs to be had about the costs of lowering the bar against the costs of early streaming. I think people are rather strongly against lowering the bar to the point of effectively removing calculus from high school based on the general reaction in this thread.

If over twelve years of math instruction you can't figure out how to teach the average child algebra, trigonometry, logarithms, and the very basics of calculus, I would advise the educators to look into why their peers in other countries are managing to accomplish these feats.

But, of course, it's easier to just throw your hands up into the air, and just bifurcate people at Grade 7 into 'good math' and 'bad math' tracks.

Their peers in other countries are working with culturally and genetically different populations. Intelligence is 70%+ heritable, you do the math, as taboo as it may be. Then add in the difference between a culture that prizes academic achievement versus one that is ambivalent or worse, prioritizes sports or music over education, and you have more than enough to explain the divergence between nations, as well as demographic groups in the US.

And what institutions are responsible for spending half of the waking hours of a child teaching culture?

[twofornone]

Parents and peers/communities. If the US is any indication, teachers are incapable of instilling appreciation for learning once scholastic achievement is branded "uncool".

[vkou]

You underestimate the impact that schooling has on culture. As a school-age child, you spend more time being socialized and educated by your teachers, than by your parents.

You think they're doing it with "Common Core" and "ethnic" rainforest math, let alone this new "data science" insanity? You couldn't be more mistaken on that. Take a look at the popular Russian and Singapore Math. Not even the smallest trace of the failing "progressive education" thinking, just a lot of solid, high-quality, direct, rigorous, focused teaching.
