Finding Hemingway
Absolutely. I hated Algebra. Could not understand it and developed mental blocks around it. Symbols confounded me. To this day. That and more complex geometry alienated me towards math. By Trigonometry I was tapping out. I did manage to get through Math 30 but not easy by any means and I had to amp my % to passing grade by basically aceing the units that I did know due to being flummoxed by the parts I never mastered.Most students who struggle with Calculus don't actually struggle with the concepts in Calculus itself, they struggle with algebra. At its core Calculus is actually pretty simple conceptually. If a kid knows how to do a little basic algebra and knows how to find the slope of a line, I can teach them enough Calculus to pass any basic first year class regardless of their background. MATH 31 for example is actually significantly easier conceptually than MATH 30 which has a variety of topics that one could argue are more complex than anything in MATH 31.
As far as the article you posted is concerned, there is some accuracy to it and some stuff that is pretty easy to debunk. I have no issue with a more spiraled curriculum. But one also has to ask...what achievement are we trying to measure and when do we stop trying to measure it. The US for example does very poorly on many of these tests. But they also have the best top end mathematics students in the world. The only country that is close is China. As I have previously said other countries that tend to do very well on such tests perform poorly in terms of producing mathematically sophisticated people, the real problem solvers so to speak.
What I personally believe we need is balance. When the pendulum has swung far in the direction suggested by the article you quote teh result is often equally as disastrous.
Lots of people are not good at math. Far fewer need be.

So for sure if there are limitations in Algebra, Trigonometry it precludes doing well in Calculus. But its because Algebra in the first case, the notation, its greek to me. It may as well be hieroglyphics.
