I can't honestly call myself "anti-woke", nor can I honestly call myself "woke". What a pain. Harping on about either one makes for a dull comment. If anything, I'd probably be considered "woke" by ideological proximity. > Is it though, or is that just what your ideological sense tells you? What aside from grade inflation explains why those students in the UCSD report had high grades but had to take remedial math cla…

There is a high signal NOW , due (very obviously) to a well-understood and well-characterized effect visible up and down social metrics in all societies where they have been measured. What I'm saying is that pretending to ignore this very obvious hypothesis in order to push a personal theory about "grade inflation" or whatever and demandi…

When I brought up grade inflation, I meant it as a factor of a different kind than { COVID, phones, generative AI, ... }. Grade inflation is the reason why the decline is deceptive.

> better off people don't think they can escape and push to make the program better for everyone. Your solution is to make the smart kids suffer so maybe they can force the educators to do better? That’s insane. It’s also not going to happen. Do you know what will happen? Any parent with the means will scrape together cash to pull their students out and go to private schools. Or they’ll hire tutors after school and f…

This gives off "I Am Very Smart" vibes. I was in a gifted program in grades 5-7, stopped going mainly because I had to travel to another school to attend and it was inconvenient. I didn't "suffer" being in classes with folks who weren't at my level. The teaching staff did a great job and I never felt like I was being shortchanged. My undiagnosed ADHD means I goofed around a lot, but several of my friends told me afte…

Do you have reason to believe he benefitted from gifted programs around the level of kindergarten or maybe first or second grade?

He never had to work a day in his life and now he's mayor elect of NYC!

The "never had to work a day in his life" claim is wrong, though I agree his experience seems insufficient for the position of mayor.

I'm not sure why this is down-voted. Nearly every single teacher I had from elementary though high school, when asked what was the usefulness of the math lesson, said that we would need it when we got to the next level of education. Elementary teachers said we would need it in middle school. Middle school teachers said we would need it in high school. High school teachers said we would need it in college. By college…

I think the GP post might have been downvoted because "what the math is useful for" frames it in the wrong way, making it sound like every lesson needs to be immediately applicable to your everyday life. An honest answer might be "this lesson in fractions is one step on a difficult 15-year journey that culminates in a junior developer position at OpenAI," but most 10-year-olds aren't ready for that conversation, so "…

The math I was taught had a lot of practical applications. Fractions for cooking, calculating tips, finance, taxes, etc. Not even that was justified to us, let alone the more advanced stuff.

Ironically enough, they just got a Pentagon contract for 6th generation fighters.

That's because Boeing is now a defense contractor that also happens to make commercial aircraft. Which is why being located in DC is important.

MacDonnell Douglas was primarily a defense contractor with a long record of subpar performance and technical failures in the service of those contracts. At the time of 'merger' with Boeing in 1997, the not-very-exclusively internal joke a was that MD used Boeing's own funds to acquire Boeing; and the years since have proven the truth in this perspective. Boeing went from being an Engineer led company which produced superior equipment, to being a Management led company which produces shareholders, and which has fully reformed to the MD model of Washington centered, defense industry, lowest bid and highest level of 'acceptable failures' in both the defense and commercial product markets. More lives will continue to be lost in a calculus of least cost risk mitigation.

The issue, as I see it, the erosion of the level of mathematical competence seen at university entrance. This inhibits the rate of progress one can make with a student over the period of an undergraduate education, and this reduces the exposure to mathematics of the next generation of educators. Mathematics education is really, really broken unless your measure is Terry Tao’s are still produced. That’s not the issue.…

Okay. A lot of the blame for this has been previously placed directly at the feet of stuff like AP programs that claim to teach, e.g., calculus to a bunch of people who aren't ready for it; it becomes a prestige thing or expected for admittance to college, which results in a bunch of people being taught to the test and not actually gaining the foundational mathematics education they actually need to understand the su…

My initial reply to you was to only articulate some nebulous idea that there is desire for mathematical understanding that is being underserved by mathematics education.

If standardized tests statistically “reliably” predict mathematical “ability”, the act of removing their gatekeeper role to higher education in our society (that is structured around prestige colleges resulting in prestige future income) amounts to disincentivizing whatever performative mathematical education students endure.

Some people, as children, are drawn to mathematical concepts and, yes, now is a better time than in all history to be such a person. The ambient possibility of this for a given individual is I assume unchanged through history.

Some people, like me, are able to do performative mathematics in school well enough but didn’t particularly care for it. Then we encounter some remarkable teacher and we feel some fortunate and enriched.

The existence of the remarkable teacher is the product of the possibility of a society producing mathematically proficient educators. That means students must somehow encounter them in their education.

I believe increasing the production of such teachers is important, irrespective of the field. I believe mathematical thinking can address this problem. Above, I have sketched the most meagre possible outline of how such thinking prepares to address further modelling of the problem.

Yes, this is contingent on my assumption that mathematics is generally useful in problem solving.

If you don’t accept this, that’s fine. We simply don’t agree. That said, I want to add that I appreciate the time you took to engage with me. I’m someone who believes that a lot of structures in society are poorly conceived, but that is a much longer discussion. At the present moment in time, standardized tests are a minor stupid in comparison to removing them without a much broader vision of how to address certain shortcomings of society.

1. A lot of math crops up in unexpected ways in everyday life. Trig in construction & wood working, calculus & integration when doing finance, &c. 2. It's not about teaching how to crunch numbers, it's also teaching general problem solving, and using tools to break down complex problems using your various tools to solve it. This translates directly to everyday life. As a programmer we use calculus and integration all…

From what I understand, 'rave' was a late 1980s to early 1990s phenomenon. It was a time when everyone had an excellent time, high on drugs. Nobody was 'calculating generator loads and building power grids' even if you had 14kW of sound system to plug in, monitor speakers and some lights obtained for the weekend from the local theatre. Electrical items would be plugged in with a slight risk of electrocution or fire,…

1. Just because a few commercial American events masquerade as raves or fedtivals, doesn't mean all events are like this. You just don't hear about the good events. We have to calculate generator loads because we're running 500-1000 person festivals with permits &c, but it's still an underground party operating by rave rules. No high vis security or police around. Also we're not doing this in the US, please don't project your shitty culture onto the whole world. 2. Aerial circus it's extremely important to inspect the rigging points and the hardware being used due to the sheer amount of force being generated by drops. You absolutely need to know the load of carabiniers, regular rock climbing ones are often not sufficient. 3. Blender could be a fun idea but you often are limited by the room and where the rigging points are, than what you can dream up.

What happens?

It seems we have entered the Find Out phase of FAFO; which FA began with a lack of preparation in US educators in the 1960's for "New Math" which focused on conceptual understanding and abstractions, such as set theory and differential number bases. This lack of preparation, especially among primary educators (who had not themselves encountered mathematical theory in their own education) led to a regression; "Back to Basics" in the mid 1970's. Those missteps; both in educator preparedness, and in systemic regression to a rote memorization approach were substantially aggravated by reduced standards testing in the 1980's to hide the resulting weaknesses resulting from this regression.

First hand experience as a student through these epochs from the late 70's through the 80's and 90's in US academia led to thinking I was 'not good at mathematics.' For me the 'breaking point' of this pattern was the discovery that even with an undergraduate STEM degree from a PAC10 university, including 'advanced' math courses available therein, I was not sufficiently mathematically educated to qualify for enrollment in a post-graduate physics program at a leading scientific institute or to participate in advanced mathematics discourse at an international mathematics symposium.

During COVID lock-down I attempted graduate level bio-molecular studies from several tier-one US and UK online university programs and ran into proctored coursework where the educators opined that "some problems are simply intractable due to scope or complexity" and I was unwilling or unable to accept that there was no approach to solutions for these systems.

The ensuing self-directed relearning from international curricula and classical resources has remedied my misconception of inability; extended my approaches to include concepts such as p-adic bases and complex topological approaches. and shows that current cohorts of US students will need to become self empowered to learn conceptual math beyond what their educators believe achievable.

Those who do not grok math will always be in the position of being taken advantage of by those who do.

Having learned math a lot in university, it is mostly useless knowledge outside of academia. Some basic calculus and logic is useful for sure, but overall, 98% of the math is needed just to be able to learn other math topics later.

As someone who loves math, I do think math education would benefit from making the primary focus be probability and statistics for high school. In addition, financial math instead of algebra. I would replace trigonometry and geometry with discrete math as electives. And have calculus as another elective but taught without a focus on calculation.

As someone who went to economics school and had roundabout the math curriculum you suggested, I think it was a terrible idea. It leaves one with the wrong idea that math is mostly about handling money. Only later, when I got to study math for the computer science degree, I realized that financial math is only a small part of this marvelous huge pie of knowledge.
