Curious what the causes are and how their weighted. Seems like it'd be too complex to actually figure out what's causing the most damage, but it's very interesting. There are so many factors I'd argue are probably negatives:

- Always online phone access (and everything that comes with it)

- Generative AI for doing assignments without thought

- The COVID year or two that they had to learn from home couldn't have helped develop good habits (I know it would've for me)

Adults can't dismiss experts and expertise all the time on every topic (climate, health, economy) and worship know-nothings, and expect their children to invest time and effort to learn stuff.

The kids may become dumber but they aren't stupid.

I know we’re not supposed to think about this, but is this controlled for region of origin? That has been changing, and so if that impacts school performance (schools designed by westerners, mind you, in a societal model designed by the same), then we would expect this to change as well right?

Just looking at the picture triggered me. Why are the students sitting in groups and cutting paper with scissors?

There’s a huge teaching gap between USA and Asia.

See for yourself:

Edit: since it may not have been clear from the video, this is my interpretation:

* in the Japanese math class the teacher teaches at the board and then walks around the class to look at the students. Students are not sitting in large groups.

* in the American class the teacher spends practically 0 time at the blackboard, the students sit in large groups, the teacher spends most of the time with one or two groups.

If it's not clear, arts and crafts sessions are occasionally included in classroom material, especially at younger ages. A single picture is not indicative of how most classrooms operate, or even how this particular classroom operates most of the time. It looks like a quick group project for a basic presentation on some subject matter.
Ignoring your huge generalisations based on one silly picture and a bunch of Asian clichés, I think you have a point when it comes to the group thing.

When I was in school, most work & learning happened on the individual level. Sometimes in pairs, where we would have to check each other's answers. But from what I see among my younger relatives and friends with children, there's a lot of group learning going on these days. Groups of five doing all kinds of projects in pretty much any class on any subject. Maybe it's fun to collectively build a diorama of ancient rome for history class, but I doubt you'll improve your maths skills much in this way.

Is this a consequence of a teacher shortage? Are kids in these groups supposed to help other kids? Are they supposed to learn cooperating with (or leeching off) others, at the cost of learning useful skills for themselves?

The majority of the public school system has devolved into day-care, not education. Most parents just watch TV, stare at their phones and don't want to be bothered by anything that requires effort. A major societal shift needs to happen for this to be reversed. It's many factors... the parents, the food system, various inequalities, social media, technology, healthcare... the solution is multi-pronged. But if I had to choose id start with social media, smart phones, tablets, etc. Technoloy needs to be seen as a tool and a resource, not primarily as the brainwashing entertainment that it is, and brainwashing them with entertainment is how most people introduce tech to their kids.
Maybe. I've definitely seen that anecdotally in some cases. But the school system is also problematic for the families that do value education and the kids that could excel in the classroom.

Our district has eliminated programs for the kids at the top end in the name of equity. They've also eliminated separate spaces for kids with learning and behavioral issues for the same reason. So everyone is in the same classroom and most of the teacher's time is spent on a handful of kids causing trouble and the rest of the class learns nothing.

We can't afford private school, so we're doing a bunch of extra lessons at home to keep them on pace, engaged, and challenged. But really, there are only so many hours in the day and I want them to be outside playing too!

It’s a function of time. For far too many people, the existence of modern life consumes more time than it did a generation ago. We work more hours, we work harder hours, we consume entertainment for more hours.

The costs of this societal shift fall on those who can’t compete for time. Student’s go unparented and unmentioned.

I graduated from high school less than ten years ago. I'm sure screens have become a big issue in many (or most) schools, but that was not the case at my high school. It still was mostly daycare, not education, so banning screens will not be enough.
> Most parents just watch TV, stare at their phones and don't want to be bothered by anything that requires effort.

You must live in a very sad place. This does not describe the average parent of any of the kids around me. I know these people exist, but it’s not the norm at least in my state.

The most common complaint among my teacher friends is about helicopter parents who are too involved.

Public school is a joke. My 5 year old started kindergarten recently. They're currently learning shapes, which she (and every other child I've encountered) knew when she was two years old.

Meanwhile at home, she's already reading. She's at the hard part, when reading is so slow that it's painfully boring. It's still too slow for the entertainment value to justify the work, so she's not hooked yet. We spend 5-10 minutes a day on it, and I suspect she'll be over the hump in 3-6 months. Public school would have taken another two years to get her there, even though they get her for 7 hours per day.

The one-size-fits-all model of education is a blight on our civilization.

Unless this accounts for the change in population demographics, it's a pointless study, or are we still pretending that doesn't exist at a macro level?
You need to look at who the kids look up to. What attributes do their role models have?
There's a longer trend but also a clear inflection point around the rise of mobile phones and social media. N=1 but we delayed getting a phone for our kid until a few months after she turned 13, which was a good choice because now we wish we'd gone longer. We can see how social media and app snacking clearly have negative effects on attention span, attitude, etc.

Also choosing to close schools during COVID was as catastrophic as many predicted. Our kid was in 7th grade during COVID and teachers each year report the effects are still being felt across many students. Of course, naturally great students recovered quickly and innately poor students remained poor but the biggest loss was in the large middle of B/C students.

We did something similar. My daughter got her first phone last month, just in time to start high school. And I'm happy to say that the school district adjusted their mobile phone policy this year from being pretty restrictive, to an outright ban. I completely support that.
I followed a different approach with my son. We gave him a phone pretty early, and didn't even have a lot of rules around it (no family controls, etc).

The agreement I had with him: "Scroll all day, play video games, etc. That is my side of the agreement. And you also do your school work, learn, practice for exams, homework, etc. That is your side of the agreement. I'll trust you. If your grades get worse, i.e. you need help managing device time, we'll review/change this agreement."

We also sat down many times looking at content together, in attempt to teach him what's trust-worthy and what isn't, what's "healthy" and what isn't, etc. And of course we do other things together as well.

So far (knock on wood) my son has managed well - he is 16 now. He organizes his own time, and has learned when to play and when to work. And crucially he has learned when to disconnect from his devices to do what's necessary.

No kid is the same. I am not saying my approach is best or even right, I just offer it as another data point.

The final answer to the perennial question "What is algebra good for?" is found in the success or failure of society as a whole. The same can be said for many other oft-questioned values, like "What does it matter if I'm a hypocrite?" In truth no-one really knows what the future will bring - it's always possible to construct a scenario where ignorance and irrationality will save society from extermination. But in the "horses, not zebras" sense it pays, I think, to play the odds and consider the most likely scenarios that put a society at risk: invasion, revolution, natural catastrophe, and then ask those questions again. Much of history can be read as a set of experiments testing various social theories, and the failure modes of not knowing algebra (Cambodia), or not caring about logical consistency or truthfulness (Russia) are well-known. Education is an insurance policy against a threat that may occur a generation or two in the future, and so the feedback loop is very long. This says, to me, that any change to education policy or practice should be very slow, incremental, and based not in aesthetics or ideology, but on the need for society's continued existence. It would be optimal to have many parallel longitudinal incremental educational experiments going on all the time, and then adopt the changes that bear fruit. It would be optimal to require that ALL educational policy makers be experts in history.
We’re also trying to force the dropout rate lower. So naturally test scores will decline.

Gone are the days you are held back. It’s a classic Goodharts Law problem. We’ve focused on one metric and lost site of the bigger picture.

States improving performance (Mississippi of all places) now are holding you back at certain milestones. IE at 3rd grade if you can’t read, 8th grade for math deficits, etc.

If kids could do math they would be able to divide the yearly American military aid to Israel ($18b last year) by the American population (340m), so they probably wouldn't conclude that fifty bucks per year per person was the main reason why their classmates are poor or their parents can't afford healthcare.
Education in the US as a whole may be on the decline, but for math specifically I’m not sure that we ever figured out teaching methodologies that work for all children. Every math teacher I’ve ever had was very theory-minded and could barely understand students who weren’t — those who learn through practical example and hands-on activity for instance usually get left in the dust.

Reading teaching on the other hand was for the most part figured out a long time ago but trendy experimental methods keep getting cycled regardless.

Every teaching method you can think of has been tried. What you are describing is called scaffolding with manipulatives which you can find dozens of for maths. Schools have also tried making worksheets catered to multiple skill levels within the same classroom.

The harsh reality: most children infamously still have a hard time even being able to tell the time on an analogue clock. You can try every method under the sun but if a child has a hard time understanding a system with two different base numbers it is usually because they just don't have the capacity. All the handholding in the world isn't going to change that.

- The Pandemic really set that generation of kids back, particularly kids who were in elementary during that time.

- Public school is essentially daycare. They try to integrate special education students more into the regular classrooms, but the teachers end up spending disproportionate time dealing with them and their behavioral issues, which hurts learning for regular students.

- I don't have strong, set in stone opinions about Common Core, but it's approach is certainly hard for parents trying to catch their own children at home. Eg. there is no emphasis on memorizing multiplication tables, but rather it's on learning rather esoteric and hard to remember (albeit valid) math algorithms.

- The teachers are generally poorly trained, poorly motivated, poorly paid, poorly educated, and poorly adapted to teaching students.

- Learning high school math has been enjoyable. I only took up to geometry in high school, but they are doing much more advanced math. I don't know any of it, and they barely do. So it's been fun learning it and then having to teach it to them in the matter of a day or two. Being a programmer has been exceptionally useful in that regard.

If public school is essentially daycare, why did the pandemic set a generation of kids back?
Because it was essentially solitary confinement of children. It's not normal for developing brains to be isolated like that.
This was trending long before the pandemic.
My oldest has done both common core math(kinder and 1st grade) and Singapore math(2nd through 5th). Both emphasize understanding over procedure and repetition. I do think in the long run it's more valuable since she has an understanding of concepts instead of just having things memorized. She never really her learned her multiplication tables as it was never required, her homework is real world word problems that challenge even me. I think it's much more valuable than rote memorization that traditional math education focused on. It's just a lot of work from both the teacher and the student. That's the challenge teaching these types of math educations over traditional math.
If you can't fail students and hold them back, poor students will continue and pull down the average of later grades. News at 11.
My youngest is now 19, but all of my kids had "common core" math in Denver Public Schools. That was an utter travesty. I had the tail end of the "new math", and it was obvious even then that arithmetic drills were monumental wastes of times. Apparently, the common core folks had not heard of pocket calculators, or calculator apps on cell phones.

If "math" does not account for reality, of course people are going to treat it as a meaningless barrier to be overcome rather than learned. Also, math is more than arithmetic. Using picture of coins. For Chrissake.

For the first years of school, it is actually very beneficial to pretend that calculators don't exist.

Students must be accustomed to do simple arithmetic without the help of a calculator, or else their mathematical abilities will be negatively impacted. Same for learning multiplication tables, recognizing the associations between the numbers is important.

Only when they begin to calculate things which exceed the number of mental tokens that they can handle, then they can start using a calculator with no ill effects.

I am not sure why this is news. Classic economic warfare.

Parents with higher education and stable incomes have the resources, time, and knowledge to supplement their children's education. This includes tutoring, enrichment programs, monitoring social media and phone use, and advocating within schools, as well as sending their children to smaller, private schools.

Most Joe Six Pack parents hand their children unrestricted iPhones and let the schools raise and baby sit them, while the parents sit back getting fat soaking up social media and TV.

Well, it's put in a bit of a disrespectful tone, but I think you are right. Unrestricted access to a smartphone will lead to 6 hours + a day screen time. And it's all addictive junk. That can't be good.

One also sees the "educational" difference. Here a study was published concluding that poorer areas have twice the number of snackbars compared to areas with "higher educated" people. Bad food is also very cheap. It's also very easy to never read about the effects of screens on childeren and I see people with kids of ~1 sitting on the back of a bike with a smartphone blaring... Why not let the kid enjoy and learn from the surroundings? My kids loved riding a bike with me.

The answer NYC schools have come to is to relax /TEACHER/ basic knowledge requirements: https://www.newyorker.com/news/annals-of-education/the-teach...

Without bonus points, DEI-hires at the school would not survive; these racist school districts need a way to ensure these lousy teachers create entire generations of people hostile to learning! The whole system needs to have an emergency cut over to vouchers.. $27k/year/pupil in NYS to get a teacher that looks like me but is functionally illiterate.

These public teachers aren't heroes, they are actively keeping us behind with their pro-union/anti-student behaviors.

Most of my friends have no idea what math and reading curriculum is used in their kids public schools.

It's different with friends whose kids attend private schools - most knew it was Singapore Math.

You may like it or not - but it requires parent effort to make sure your child uses their most valuable time to learn something.

My parents didn’t care about the details of my education yet I did well. I don’t think most parents ever cared so it doesn’t explain the decline. I had discipline instilled in me however, and I am guessing that’s what is lacking nowadays.
Good source of factory labor.
We have a powerful right-wing political party that is aggressively anti-academic.
Most of the comments are focused on the supply of education. But I don't think the supply side is the problem, irrespective of teachers and high schools. There is more and cheaper education available than ever before. Nearly every highschooler has more access to learning that kings and emperors would have fought wars for less than 200 years ago. However,the United States, particularly in the last 50 years, seems to have fostered a culture averse to education. I believe the years long decline in test scores is a symptom of that cultural shift.
Just look at HN. Nominally an educated crowd, but talk about physics, and you immediately see terms like "ivory towers" or "return on investment", despite the fact that most on HN doesn't understand in fundamental science works.
> However,the United States, particularly in the last 50 years, seems to have fostered a culture averse to education.

!!

The rate of college graduates has increased nearby 50% over that timeframe.

A rather unexpected result for a cultural aversion to education.

most students are going to college because many jobs require it, or because they were “pushed” into it by teachers or parents. Not because they value education in the slightest.

I went to a state school and was one of the “weirdos” that didn’t party or join a fraternity. IMO some of us are there to learn and socialize on the side. Others are there to socialize and learn on the side.

> or because they were “pushed” into it by

That's literally the definition of cultural influence

It’s culture led by phones and other screens. Most teens are addicted to the screens. The need them for school and for socialization with friends and they end up on TikTok or another network and zombie there for most of their best brain years. They lack the ability to focus necessary to learn because the brain is used to constant screen simulation. Letting your child be babysat by a screen is absolutely the worst thing you can do to ever raise an adult.
The decline in the last 20 years was more noticeable, and the last 10 far more noticeable.
My kids don't get textbooks in public school, are comingled with highly disruptive kids (except in the limited gifted classes) and the curriculum is accelerated way past where it was when I was younger.

So my anecdotal theory is that the (public) education system is optimized to the edges, abandoning the middle entirely, resulting in majority decline.

They do get computers with TONS of dumb-ass apps and zero reference materials.

The problem with that “culture” explanation is that white kids in America do fine in international educational comparisons. In the 2018 PISA assessment, 15 year old white american students were near the top in reading (behind only Singapore and some Chinese SEZs) and in the top echelon in science (comparable to Japan). Their weakest performance was math, where they’re around the middle, behind the top asian countries but only modestly behind Finland: https://nces.ed.gov/surveys/pisa/pisa2018/pdf/PISA2018_compi....

Insofar as the US had a “culture averse to education,” surely that affects white americans as much as it affects anyone else. But, on average, they are not the ones who are behind their peers internationally.

not surprised you lose what you don't use, does modern world even require people using those reading and math skills anymore?
> However,the United States, particularly in the last 50 years, seems to have fostered a culture averse to education.

I always find it interesting that the anti-schooling mentality is so prevalent here on HN, too. It’s most obvious in threads about cheating, where a popular topic of discussion is to defend cheating as a rational reaction because school doesn’t matter, a degree is “just a piece of paper”, and you’ll learn everything on the job anyway.

It also shows up in the tired argument that college is only really about networking, not learning.

I’ve had some on and off experience mentoring college students in the past. Those who adopt these mentalities often hit a wall partway through college or even at their first job when their baseline intelligence runs out and they realize they don’t have the necessary foundation because they’ve been blowing off coursework or even cheating their way through college for years.

I’m afraid that LLMs are only going to enable more of this behavior. It’s now easier to cheat and students are emboldened by the idea that they don’t need to learn things because they can always just ask ChatGPT.

The cultural shift is secondary to the demographic shift. Young Americans have been squeezed at one end by mass immigration from countries with lower educational performance and literacy rates, higher crime rates, higher gang participation rates, etc., which accelerated to such an extreme that native English speakers are now a minority in our local school district. And they’re squeezed at the other end, forced to compete for college admissions, jobs, and housing against a hungry and ambitious global population vying for H-1Bs and student visas. We sold out the younger generation, our own children and grandchildren, and it wasn’t at all driven by political and corporate machinations. No, it was for some greater good, and if you dare question that you’re a fascist.
> There is more and cheaper education available than ever before.

The real issue isn’t the availability of learning materials, but the healthy pressure and right push from experienced teachers. People tend to overestimate how self-driven most students are. The truth is, most students aren’t naturally motivated to learn. They need society to give them a sense of purpose, and they need teachers to challenge them with problems that keep them just outside their comfort zone. Sadly, the U.S. school system provides neither. Take my kid as an example: even though he’s in a decent public school, he thinks his schoolwork is tough and the SAT is challenging. Yet the SAT wouldn't even measure up to the high-school graduation exam in my country, let alone the college entrance exam. In the end, it’s the broad middle of students who suffer from low standards. With the right motivation and push, they could learn so much more, but instead they end up wasting precious time in high school.

I don't know about this. In my community atleast, most kids want to do the best they can in school and feel more pressure than ever for admission to top schools - who are more selective than ever. Particularly since competition for knowledge economy jobs is tighter than ever.
In my community, it’s both. The referendum to continue funding the teachers who supported the advanced math and reading classes didn’t pass.

The referendum didn’t pass because a large swath of the community saw no value in having advanced math and reading classes. I have no doubt there was a lot of “I didn’t go to advanced classes and I turned out just fine, that’s a waste of money” thought process.

That’s one hypothesis: American culture is degenerate.

I offer an alternative hypothesis: corporations influence policy.

Corporations would simply prefer to import skilled workers than to have to pay taxes to educate Americans. Evidence for my hypothesis can be found in Vivek et al’s endorsement of the lazy Americans hypothesis. It is a narrative the GOP gets from corporate donors and not from Joe Sixpack fox tv viewers who make up the base.

In the US there are a few obvious things, but everyone acts as if we are powerless to solve them:

1. Cell phones in classrooms.

I don’t know how or why they were ever allowed. They should have to be in a backpack or in a locker and off during class.

2. Not removing students with bad behavior from classrooms and schools.

The current thinking on how to handle a student who is seriously misbehaving and potentially violent is to remove all of the other students from the classroom versus just removing the problematic student in question. This is because there have been instances where a child has been physically removed and has gotten seriously injured. The thinking on expulsion is that it should essentially never happen because kids who get expelled have bad outcomes later in life. But the net effect is that one bad student can hold an entire classroom hostage and there is nothing the teacher can do. This is obviously detrimental to all of the kids who are compliant and behaving. It also causes burnout which leads me to the next major issue facing public schools.

3. Good teachers are quitting

It isn’t worth it to teach in America. You need a lot of expensive education. You get paid very little. You have no power to remove a student who are major disruptions and make it impossible to teach. And, in many districts, teachers are being accused of trying to indoctrinate children because we live in a politicized world.

4. Too many parents aren’t parenting

The number of kids who are not potty trained by kindergarten continues to rise. This is an issue of parents not wanting to do something that is hard and takes patience.

5. Lowering Standards

When faced with kids failing the solution should never be to lower long held standards. The kids are the same, they are just as capable, it is all of the above that is different.

Bonus. We feed kids junk in schools

This has been going on for decades. Why is it so hard to make fresh food for kids? It could probably cost about the same if done properly. The answer is it takes some effort and people have to think about it.

From your list it's hard to explain why jurisdictions such as San Diego (reading 4th grade male) test score have risen continuously since the 2000s seems like, if the students are defecating themselves at ever-increasing rates test scores would go down there too.

Or is San Diego immune to these problems? I think the reality is that these test scores aren't majorly affected by literally any of the things you listed.

> However,the United States, particularly in the last 50 years, seems to have fostered a culture averse to education.

There's good reason for this. Not everyone enjoys learning for the sake of it. The pitch for forced education is that it will help you sustain yourself as an adult. If adults are finding their time in forced public education to be regretted, then they pass that information onto the younger generations. Maybe there are better ways to acquire useful skills.

I'm always a little surprised to see the HN crowd so in favor of education. The median commenter writes programs for a living, and probably acquired that skill mostly on their own. They might enjoy learning for its own sake, but surely they can look at their own situation objectively and realize their marketable skill came more from free time, computer access, and internet access, than an educational institution. If the strategy was to bet on what already worked for oneself, and hope it works for others too, then they would want to pull money out of schools and put it into libraries, computer labs, and internet cafes.

It's easy to blame culture. It's kind of a thought terminating cliche. Once you've assigned blame to a general attitude among the public there nothing much to be done.

We could examine the common differences between US education and other high performing nations and try to reform towards something more effective, but really culture is the problem so let's all pack it up and find something else to worry about.

I think the one way that American culture does prevent progress is that Americans tend to be averse to evidence based reforms. They like to atomize responsibility for everything down to the individual. Homelessness, drug addiction, poor education outcomes, poor health outcomes, it's all just individuals making bad decisions or perpetuating bad culture.

If we did anything that actually helped it would somehow be condoning/encouraging the badness of these individuals. Regardless of how effective it would be it's somehow worse than allowing the problem to fester.

Also, high schoolers who see their advanced degree-holding parents out of work for months or years at a time may begin to wonder if the effort is worth it - education is a lot of work for comparatively little benefit.
but

it being available "on the internet" doesn't mean it' available to a child!

it also misses the important aspect that for children you need to nudge them into the right direction of learning

it also misses that children today often get bombarded with a non stop stream of skillfully engineered distractions and dopamine loops, that makes it much harder to nudge them in the direction of educating themself.

oh and all the fake news, fake education etc. isn't helping either,

You're sort of not allowed to mention culture in the context of education. Otherwise people might realize that different cultural groups have very divergent education outcomes. For example, Asian students study 2x as much as white students and 3x as much as black students. It is likely not unrelated that Asian students have much better educational outcomes, regardless of class. For example, Asian students whose parents have no HS degree perform better on the SAT than black students whose parents have a doctoral degree.
