Plunging test scores are a slow-moving catastrophe

This very much echoes the region of critical slowing down present in a dynamical system after its equilibrium states have disappeared due to a change in the system (a bifurcation).

2h agoHN ↗

A bifurcation is a non-continuous change to a system as a result of a continuous parameter changing.

For example the disappearance of a stable temperature of the earth due to a continuous increase in green house emissions.

In this case the change in test scores is continuous yet might still lead to the disappearance of a stable point in society like white-collar work. At the start the change might seems slow but the point of no return could have already been passed.

I'm not saying I necessarily believe that (or that I stated it with much clarity) but I thought it was interesting how it "rhymes" with dynamical system theory.

2h agoHN ↗

Something changed and adjusting is slow

Rearranging the deck chairs on the Titanic.

2h agoHN ↗

The good news is the ocean is vast. You don't need to be on a Titanic.

2h agoHN ↗

I wanted to relate the result to well known phenomena in Dynamical systems. The value of the comment is in that relationship. But I guess I can try.

After a saddle-node bifurcation (for example) a system is left with a region of critical slowing down. It can be thought of as the ghost of the fix point that used to exist in that region. Thus observing local phenomena in the system can make it look like the system is still stable while in reality it isn't.

I guess the most famous example of this is global warning. As our emissions of greenhouse gases increased during the industrial revolution, the environment still seemed stable. But in reality we had already deleted the stable point around with our planets temperature oscillated.

2h agoHN ↗

Is your point that earth is not at a "stable point" or "stable range" but it used to be?

Or are you talking about another system like "society" or "civilization"? Or something else altogether?

2h agoHN ↗

Society, education and white-collar work in this case. Not saying I believe this does mean the collapse of white-collar work of course. Moreso that if that was the case, the point of no return could have already been passed without us knowing.

2h agoHN ↗

For something as abstract as education, is there such a thing as a "point of no return"? It's not obvious to me that's something that degrades in the same way that climate or a physical system does, even if we can draw some parallels. I do think it's still a useful analogy, for example, it would imply that even though we're only starting to notice the ripples of that instability now, it has the implication that fixing it things would mean having to address much more than just what's apparent, we'd also have to fix everything that lead to this mess over the last few decades.

1h agoHN ↗

I think there is for a snapshot in time of education or work which is how we commonly think of work right? It isn't true of course. But we sort try to group work into periods of stability between revolutions, industrial, digital or whatever.

We have a chance to adapt, that's for sure. But white-collar work might not exist (or just resemble) as it does today.

But I agree, the category is almost too malleable to analyze.

2h agoHN ↗

Everything is a wave and there are always oscillations.

2h agoHN ↗

Where is the slowing down? What causes it?

I can see there a compounding drift from the stable point that is not initially apparent because the compounding values have not yet grown sufficiently to be meaningful. It is still an increase in drift

Slowing down implies a decrease though, what does that represent then?

1h agoHN ↗

I think we see the slowing down primarily in hiring right?

2h agoHN ↗

Holy sentence... George Orwell must be turning in his grave right now.

2h agoHN ↗

A sentence isn't Orwellian just because you are unfamiliar with its terms. I though dynamical systems theory was quite common knowledge among engineers

2h agoHN ↗

The issue is that you're talking in abstraction and it isn't clear what the concrete thing is you're thinking of. Bluntly: you're being obscure rather than illuminating.

For instance, with respect to this article, which is about test scores, how does dynamical systems theory describe what's going on or predict consequences?

2h agoHN ↗

What do you think Orwellian language means?

2h agoHN ↗

Orwell's 6 rules for good writing:

1. Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.

2. Never use a long word where a short one will do.

3. If it is possible to cut a word out, always cut it out.

4. Never use the passive where you can use the active.

5. Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.

6. Break any of these rules sooner than say anything outright barbarous.

Seems highly plausible AI/robotics will lead a significant decline in public schooling in the near future. Kids honestly might learn better doing a few hours a day one-on-one with 2026 frontier AI than sitting in a classroom of 30 with a teacher. 2027, 2028, 2029?

Modern public education itself is industrial revolution technology. Why would it be left as-is after the intelligence revolution?

2h agoHN ↗

No, they think they learn, then when they need to use that knowledge it turns out they learned nothing.

2h agoHN ↗

Exactly. Calculators didn't make the typical person great at math. They obviated mastery of math.

2h agoHN ↗

Math or arithmetic ? Math isn’t arithmetic any more than juggling is theoretical physics.

Mastery of arithmetic involves memorizing lots of heuristic rules that aren’t particularly insightful about, or are outright conflicting with, the structure of math, and learning the structure of math first slows your ability to do arithmetic.

I don’t think any school hands first graders calculators and asks them to never learn arithmetic. But I see no need once you’re doing algebra to be focusing your time on long division or multiplication. These are irrelevant distractions from algebra, time spent and points lost on arithmetic details is a waste of cognition and doesn’t help. This becomes increasingly true through calculus, linear algebra, until you get to real math courses where a calculator is pointless because arithmetic doesn’t even show up.

1h agoHN ↗

Multiplication needs to be automatic for doing algebra: FOIL and factoring polynomials immediately come to mind.

Long division, at least conceptually, is also present in algebra and partial fractions.

1h agoHN ↗

Similarly, algebra needs to be automatic to do calculus.

Everything builds on everything else.

2h agoHN ↗

There is a 99% probability this will not happen in your lifetime. Half the point of school is so someone has supervision over children for 6 hours and to be part of a small community.

If anything, if someone is looking for an AI proof job while not wanting to do something braindead, teaching might be one of the good jobs that may get more competitive.

1h agoHN ↗

AI improves a student's ability to learn. It does nothing to improve a student's motivation to learn.

Motivating students to learn is not at all a solved task. And arguably a harder one too. Even the ~2010 "Google and grit" self-teaching is enough to outperform public education - but most students don't have the motivation to pull that off in practice. They have the opportunity, but that matters little if they don't use it.

1h agoHN ↗

Modern public education is just state subsidized daycare to keep the population at their 9-5.

1h agoHN ↗

That's a very attractive idea. KhanMigo was supposed to embody that potential. Seems like it hasn't.

Some kids really enjoy learning. Never mind merely solving an educational assessments problem, personalized learning seems like it has the potential to unlock a lot of intellect across the population. And yet.

2h agoHN ↗

While kids practice the skills of the 21st century, testing got stuck in the 19 hundreds.

I see kids train edge AI models, built things using coding assistants and discuss post-modern philosophy.

I see the same kids struggle to write structured interpretations of 1950s texts they have no emotional connection to.

Kids are worse in orthography, handwriting, and reading stuffy texts from front to end, but they are so much better in a plethora of skills that did not exist 20 years ago.

2h agoHN ↗

This is a superficial take.

Kids are worse at reading, period. Not just stuffy texts from 50 years ago, current stuff too according to the research.

The "skills" you claim they are learning have such a low barrier to entry they aren't skills at all.

Instructing a machine "make me a Foo" requires no thought.

2h agoHN ↗

I saw an ad with a guy saying he doesn't write e-mails because he can just speak to the machine, and then the AI does it for him.

Guess we'll live in an illiterate society soon...

2h agoHN ↗

how is "worse at reading" evaluated?

test taking is not a valuable skill. it's mostly pattern matching against the question

people need new skills in a new age. the education system hasn't even kept pace with the existence of the internet, let alone AI

1h agoHN ↗

You read a text. Then, you are asked a series of questions to assess your reading comprehension. Rinse and repeat for a school year to get a solid idea of each student's proficiency.

This skill has been declining steadily since the 1970s, but the decline has accelerated since the mid 2010s. Eventually the productivity boom should take a hit when newer generations struggle to understand basic tasks and the older generations retire. AI is probably orthogonal to the solution space.

1h agoHN ↗

my point is that evaluating reading comprehension is typically done as a test, and test taking is not a valuable skill

the evidence is that individual workers are more productive than ever, and this trend has continued since long before the 1970s. this is despite any measured decline in reading comprehension

the older generations are obviously not propping up the world economy through their singular reading skills

52m agoHN ↗

Individual workers is a rather nebulous statement without citing how the measurement was taken. Like if you have 9 people with zero money and 1 person with a trillion dollars, on average everyone is a multi billionaire.

The vast majority of our production comes from more and more highly automated tools. The concentration of skills to build those things can skew the results in the short term and lead to new and interesting problems long term.

26m agoHN ↗

Find a way to test informally, like taking metrics on the number of times that someone misunderstood written questions, instructions, or requirements at work. If it was possible to measure that cleanly, I bet you’d find a similar trend.

I often find that people simply don’t read anymore beyond a sentence or two, which makes it impossible to communicate complex ideas. If it can’t be expressed as a bullet point, it may as well not exist.

1h agoHN ↗

how is "worse at reading" evaluated?

I cannot believe you're seriously asking that question.

people need new skills in a new age.

If it's a skill that is picked up in minutes, it's not really a skill.

2h agoHN ↗

Kids are not training LoRas without a big budget. I fought for $5 from my parents, I could write C for free.

2h agoHN ↗

Yes - the older I get, the more obvious it is that the mind of a child (and young adult) is better suited to learning, reacts faster, and is more creative than mine.

The attention-deficit that is so common among especially (but not only) young people today means that grabbing their interest is of paramount importance to their learning. Just repeating that kids are bad at reading stuffy texts. But if you can put them onto something that they find interesting, they can definitely excel. I've got tales of high school students who are terrible students, but give them a CAD and 3D printer and they will solve any problem you have.

So - in other news, education is broken. How do we fix it?

2h agoHN ↗

Education isn't broken, it's gotten too conservative and not able to keep up as a result.

2h agoHN ↗

According to PISA they did change the tests to be more relevant to using computers. Reading tasks are mostly practical: websites, emails, forum posts, comparing multiple sources and judging whether a source is credible.

So this "old testing" framework is at least from 2010s rather than from 1950s.

2h agoHN ↗

I see kids ... discuss post-modern philosophy

Tell us more?

2h agoHN ↗

None of the things named in your comment, on either side of the line, really matter.

Reading, writing, and critical thinking skills matter. You don't have to "write structured interpretations of 1950s texts [you] have no emotional connection to" or practice "handwriting, and reading stuffy texts from front to end" to develop those skills (very loaded language, nice job!), but you have to put a lot of time into doing something, ideally somethings, where you're the one doing the heavy intellectual lifting.

Or, we can just write these kids off as a generation incapable of thinking or building by themselves without AI tools that do the thinking and building for them. Honestly, it's probably already too late. The way we've allowed kids of all ages to be exposed to these tools is basically equivalent to handing out cartons of cigarettes in a preschool.

2h agoHN ↗

One of the weirdest things I noticed when people around me started having kids was how immediately they picked up on their parents obsession with their phones, and would instinctively try to interact with them.

It was odd, disheartening and almost universal (barring the parents who went full 'my kid doesn't use any of the products I build')

1h agoHN ↗

Why is that weird? I remember when I was a kid, I tried to imitate what my parents were doing, too. Lucky for me, we didn't have smartphones at the time.

I picked up tinkering and sitting in front of a computer from my dad. And, even then, my parents would prevent me from doing this too much, and send me to read a book or go outside and run around.

A society is self similar because a huge portion of our social actions are not thought about but copied. Being a parrot saves a massive amount of energy in descending the behavior gradient.

2h agoHN ↗

I teach college… you rent wrong on what they output, you are wrong on the inference drawn from it.

On a regular basis I have students bring me “machine learning” models they have trained, which sounds great. But they have no idea what problem they are solving, what data they have or should have, and no idea why that method, etc. There is no understanding. They use words and concepts from a broad variety of fields, with confidence, but with little deep understanding. The Internet and AI give access to knowledge which is necessary but not sufficient for wisdom.

While K-12 bears a lot of blame (as a system not “teachers”) I’ve come to believe the problem is more societal. What we value and what kids logically perceive will be them ahead in life. If all they ever see is that surface level performance of knowledge is enough…why bother with more?

2h agoHN ↗

they are so much better in a plethora of skills that did not exist 20 years ago

Such as?

1h agoHN ↗

If they have no emotional connection to texts from the 50s, then how are they discussing post-modern philosophy? Or rather, how shallowly?

1h agoHN ↗

1950s texts

The Hobbit was published in 1937 and The Lord of the Rings was published 1954-55.

If the kids can't develop an emotional connection to them, that says much more about their teachers than it does the children or modern times.

There is a very high correlation between national IQ and PISA scores. We know that IQ is declining across the world, and it is declining because fertility and IQ are negatively associated. It's likely that declining IQ is a nontrivial factor for why PISA scores are declining. It is unfortunately still taboo to talk about this. Which is bad, because we can't hope to do anything about it if we don't face the truth.

2h agoHN ↗

IQ is not measure of intelligence, it's more like curriculum test if you go into history of test and how it started.

1h agoHN ↗

No serious person in the field agrees with this.

1h agoHN ↗

I think there is ample evidence IQ correlates with lots of things like job success, performance in mental work, income etc to the point the military and many organizations require an IQ test for sensitive tasks. To dismiss it as curriculum memorization, which I think is what you are hinting at, is demonstrably incorrect.

57m agoHN ↗

Outside of science it seems to be that people measure intelligence as "what I feel I have" and nothing else.

Memorization and recall is a huge building block of intelligence itself. Almost everything we call intelligent has some kind of memory to store and work on problems. The more storage you have the more potential intelligence.

59m agoHN ↗

How about this, an IQ test developed in the society you have to survive in is a good indicator of outcomes.

If you want to be a pendant about it then there is no such thing as a comprehensive intelligence test at all as there is no universally agreed upon definition of intelligence. But that's not very useful either.

2h agoHN ↗

I saw a post where they showed that ethnically native students in Northern Europe are doing just fine, it’s the non natives, which are up to 30% and even higher in som countries, that are doing poorly. Do they actually look at that in these studies or it’s swiped under the rug as something too inconvenient to discuss? If this is fake news, please correct me if you can show the real figures for this.

1h agoHN ↗

It's because it's inconvenient to discuss. What you said is the actual truth.

2h agoHN ↗

The drop from 2018 to 2022 is as big as the one from 2022 to 2026, so it's not obvious whether AI had a role at all, although it's highly plausible.

I suspect the bigger culprit is the optimized monetization of human attention, because pre-algorithmic social media doesn't seem to be as destructive. The fact that science wasn't as affected as math and reading (both of which rely more on attention/practice than rote memorization) somewhat supports this.

2h agoHN ↗

Between 2018 and 2022, we saw the widespread adoption of social media and the rapid digitalization of education. Focusing on these key shifts, it seems clear to me that any kind of electronic learning has had a negative impact on education :p

2h agoHN ↗

You make it sounds like you're being sarcastic. But I would argue that ubiquitous digital interfaces demanding our attention is wreaking havoc on people's focus.

2h agoHN ↗

Another modern problem with education is that every student has a smartphone now, which they bring to the class, then they get distracted by it.

1h agoHN ↗

"Modern" education isn't modern at all. It's a leftover from industrialization, aiming at producing easily controllable worker drones.

"Elites" fearing the "plebs" to question them on things they have no good answers for is what constrains active development of actual modern scientific concepts of pedagogy taking hold. You only get to research what is being paid for.

Look at the, pretty obvious, natural human child-mode of learning: playing games.

Just not escapist nonsense games. Games that model relevant aspects of reality in an engaging way. Where you can fail without real-life consequences and learn from it while enjoying yourself.

1h agoHN ↗

Playing games as a biological creature optimized to live on plains is great, your body has a lot of the lessons already encoded in DNA.

When it comes catching up to the last 10,000 years of human development everything tends to get a bit trickier. Play is a good way at learning, but as you get to higher concepts you have to learn but are hard to game it gets a lot trickier.

Trying to easily wrap this up as the elites vs you is highly reductive. Before that age you' have spent most of your time and effort making food and clothes, not active research into the world.

22m agoHN ↗

They're not wrong though, like, it is a creation of the industrial era, and honestly, the "elites vs all of us" isn't exactly crazy. Mcgraw Hill is literally owned by Apollo Global Management, don't just take my word for it, look up the relationship the management there had with Epstein.

It doesn't have to be a conspiracy even, it could just be that terrible incentives across the board result in terrible outcomes lol

21m agoHN ↗

It doesn't have to be a conspiracy

“Versus” implies intent. Apollo owning McGraw Hill doesn’t explain falling scores across the entire OECD.

I worked for an education tech company in the 90s. Seemed to clear to me even then that computers in the classroom were not going to be a positive influence. The way things have gone since then, it is no wonder that kids’ brains have turned into pudding.

I think that computers in the classroom can have a tremendous positive influence in specific areas when see with correct guidance. I think where we went wrong is replacing the classroom with ChromeOS and iPads.

What are you talking about?

Between 2018 and 2022, we had a global pandemic hit!

The only reason we were "digitalizing education" is because millions of people were getting sick and dying. Millions more lost their jobs.

Trying to blame any single aspect of what happened during that period, like moving to remote learning, is hopelessly myopic and blinkered.

Hmm, did anything happen in 2020 to disrupt the entire education system?

1h agoHN ↗

the event in 2020 would've only been the last straw in a series of bad policy in education. It might've brought forward this same outcome a few years in advance, but it isn't a root cause.

1h agoHN ↗

Yeah, I am genuinely confused how the grandparent comment just glossed over it.

I believe that both COVID and LLMs are disrupting educational metrics. But in terms of which one did more short-term scale damage (i.e, within 4 years), I would wager it was COVID.

1h agoHN ↗

Wouldn’t there be recovery? Especially for the cohort that started school after the end of restrictions.

A continuous decline across both COVID and llms points towards a different causal relationship to me. I would be more likely to believe algorithmic social media or computerized teaching tools are to blame, but that is pure conjecture.

29m agoHN ↗

The cohort that started school after the end of restrictions is not 15 yet, so no recovery can be expected until the 2029 PISA test or so.

1h agoHN ↗

But if the drop between 2018 and 2022 was AS LARGE as the drop between 2022 and 2026, this implies that something happened that was as large as a global pandemic for students' education happened in the last four years. I believe the OP is implying this could have been AI. However, something else could be happening, such as use of phones and other devices or another fundamental problem in the education system.

1h agoHN ↗

The trauma from lockdowns does not disappear overnight! It is compounding damage, that gets worse every year!

And we can not just change childrens habits, after we forced them to sit at home for 2 years with nothing but youtube! They missed key developmental phase!

31m agoHN ↗

The "trauma" from staying at home? Please. If the parents let them watch youtube for 2 years then the parents were stupid. I have 3 kids in school, all but one of them were in school at the time. Staying at home with Grandma and Papa while they did zoom school didn't break their brains. You know what my kids don't have? My kids don't have a smart phone. You know what my kids don't have? Unlimited access to devices.

Now, I will say that the Pandemic was pretty traumatic here in the US, at least a million people died last time I looked at it. Those people were somebody's neighbors, grandparents, uncles, etc. So maybe the realization that "nobody gives a shit about you except for your productivity" was a lesson they internalized?

Largely, I think it is the parents though. Like I said, I have kids, and when their grades slump, I get on them to fix it. A lot of people are really unwilling to do that.

54m agoHN ↗

- Students who entered the education system in the COVID years are still taking tests today. They didn’t automatically relearn everything.

- Schools have not gone back to pre-COVID practices. Online courses, use of digital tools, fewer tests, dropping SAT/ACT requirements, and most of all budget cuts in school districts – all are still happening today.

I find this article to be more interesting: https://www.economist.com/international/2026/09/08/are-teena...

Especially the part where it states that part of the issue is in 2000 when Finland had higher test scores then everyone it was attributed to play based learning and less testing. Everyone immediately jumped on this, because if you can have more fun and learn more, of course that is the way to go. This opinion still permeates both teachers and parents. I was of this opinion for a long time, as I went to a rigorous school, and would have enjoyed "play based learning".

It turns out this may have been way off and difficult schools such as those in China and Singapore have the best results. In the Finland example they had only recently switched from more rigorous to more play based, so the rigorous schooling was still being shown in testing. I think we were all a bit bamboozled by this. Maybe it seemed too good to be true and we should have been more critical of the findings. But the play based learning opinion is still strong and we as a society need to move back to more rigor will make stronger students.

Don't Finland, China and Singapore have the highest IQs of any countries? Why can't that be the answer? To me, what you do exactly in school is likely pretty secondary.

When my daughter was in kindergarten, it was common to walk your kids to school, then let them play in the playground while chatting with the other parents, until the bell rang.

One mom told me: "I like the American school. It's like Singapore, but with fewer beatings."

Reductiveness is under the surface of many of these numbers. Finland has high teacher salaries, which is a contributing factor but entirely outside of the way teaching methodologies are evaluated.

Chinese students can work like fiends because they are in competition for a shortage of seats at elite universities. Not too surprisingly they burn out or they slack off once the pressure is off.

My personal experience with self-paced learning in middle school tells me that some students are capable of blazing through a curriculum at 3X the normal pace of classroom instruction, under no pressure at all. Technology can enable self paced learning, and it's really the only answer to scale it up. So it's hard to blame technology for screwing up education.

I mean, I always was. My rule has always been - if something seems too good to be true, it is.

This is my biggest issue with ‘progressive’ types. They always seem to get drawn in by hype and flash, and neglect to consider 2nd order effects. I’ve had an endless number of conversations with friends of this persuasion where I point out very very obvious problems with some hot new idea they are so enamored with, which they inevitably poo-poo as me being a mean old cynical conservative. And a few years later we end up with articles like above.

In somewhere that period of Finland education system I remember there being testing. Just not large scale standardised testing. But everything did have tests. Still teachers did have quite large freedom even if criteria was state level. Also it was very much traditional lessons with only occasional small scale group work.

One impact for later time was increased immigration and challenges of integrating increasing amount non-native speakers in same system that used to have nearly exclusively native speakers.

A very long time ago, in the 90s, we really thought that computers would make people smarter. We thought computers would sharpen people's analytical skills with logic and math, would provide them better tools to write and design things, would provide them information to help them get better answers.

Back then, there was a famous snake-oil salesman that coined the expression "computers are bicycles for the mind". He proposed an analogy: when you compare the effort humans put into personal locomotion on foot with other animals you'll notice that they spend a lot of effort to yield very little movement. But then you put them in a bicycle and things change: humans can move a lot with very little effort. Computers would do the same: increase the mind's "productivity".

Fast forward for today and we live in a world where everybody has a computer in their pockets. Ironically this change was pioneered by that very same snake-oil seller.

And when I see the consequences of it, I say to myself: "boy, we were soooo wrong!".

Law of unintended consequences? Or it is the fact that everyone is lazy and do want to remain dumb?

It’s still possible. There’s this sort of guerilla education movement in software with apps like Mathacademy and Mentava to really focus on actual learning, in a scientific way. I can say for my part that my son has been using Mathacademy and the results have been incredible.

The reason most educational software is not like this, as far as I can tell, is that the incentive structures aren’t there. Maximizing learning just isn’t a priority for most schools.

For this new breed of software though, they’re selling to parents, at fairly high prices. Some parents really care about their kids actually learning, and so the incentives are much more direct and aligned.

Does math academy still start at 4th grade? How do you compare it to beast academy or AoPS? What incredible results have you observed?

I hadn’t heard of Mentava, how does it compare to Lexia Core 5? I’m a little skeptical of claims like “my 2nd grader reads at a 4th grade level”. I’m privy to the standardized tests and I found the grading super inflated.

It is a bicycle for the mind, but the mind still sets the direction. Sometimes it's going faster towards a dumpster.

Here, let me revise that expression: "computers are ELECTRIC bicycles of the mind". You know this feeling, and we know it's how humans operate: when given a choice, we will ALL take the easy path. School is hard, learning is hard, and it all takes years and years of effort. Give a child a computer, or a smartphone, or AI, and all of a sudden, we don't have to expend any effort, like that electric bike. I shut my brain off and trust the ride, because it is effortless. Forget the part about having UNDERSTANDING of why things are true or false, why things work, how they work, how physics and mechanics and chemistry ALL are needed to create things. As an engineer (retired), I see youth having great KNOWLEDGE at their disposal, but feeble to no UNDERSTANDING of how things work, why they work, underlying mechanics, underlying theories, etc.

Ask any youth today about the smartphone in their pocket. Do they have any inkling of the decades of research and development for that device and it's capabilities to coalesce into what it is today? I mused once on some public forum about the inverse square law and how it applied to the fantastical ability of a smartphone to connect with a cell tower 5 miles away. The power received by the tower is approximately 3 times 10^-13 Watts or -95.15 dBm. This, to me is almost magical. Yet the forum members did not even know what the inverse square law was. They just ridiculed my comments and literally downvoted my musings to zero. I can't comprehend the ignorance of today's society.

Rote memorization is very ineffective way to memorize things. That is why it was downvoted.

1h agoHN ↗

Not sure why this was downvoted. Memory is one of the most important skills imo

Having a good memory enables you to think deeper - if you remember certain concepts, you can reason better because you remember more concepts so your thinking is more in depth.

There's memorising and there's memorising.

My history lessons at school were entirely "here's 30 dates of these important events happening, there will be a test at the end of the month where you have to name the event at each of the given dates". I just remember sitting there trying to somehow remember what happened on each of those random dates, what event was it that I knew nothing about with zero context other than the fact that it happened. I can confidently say that after I ended my formal education I remember 0 of any of those dates. That approach to teaching history is just completely wrong, I would have loved to be told WHY certain things happened not just when they happened, but the system wasn't designed for it.

But maths formulas or even chemistry and physics - yes, that makes a lot of sense because you need to remember them and then you can actually use them to solve problems later.

51m agoHN ↗

Yep. Even for maths, knowing why is king. Once you understand maths there is a whole bunch that makes sense and you can just derive.

More things in memory also leads to making more connections / recognizing more types of patterns more easily.

There are things that you just see/know/recognize that are not easily searchable/promptable because the fact that you should be searching/prompting would not occur if you had not seen the pattern before.

One could argue "experience" is just the accumulation of memory such that you can recognize more patterns more rapidly, short circuiting bad decisions before they are made. With LLMs its even more important to have a well tuned "what should be getting built" mental framework if that becomes our primary job.

I think most people don’t bother to use the reading and writing skills they did learn, so I doubt this is as big a deal as people think.

It's a cycle. Affluence of food, goods and tech removes natural survival instincts due to lack of struggle and need. That would cause the affluence to go away, rekindling the survival instincts through struggle. The cycle repeats. Different geographies have different phase delays in this cycle. Sometimes the cycle is affected by artificial forces such as dominance of a nation and it's control over the global matters. But the cycle just pushes forward.

Where I live in the US there is a movement to A) Prohibit phones from being used in schools B) use textbooks again instead of digital texts C) use handwriting and notebooks instead of Chromebooks for in-class note taking.

While this might help, and I agree with all these steps, I'm concerned that the root of the problem is simply that the online experience has rewired our kids. Not screens per se, but the feeling of a constantly moving social space which demands their attention.

There's a whopper in the middle of the article declaring an outcome "high test scores" is a cause, not a result, of a lack of a wide variety of social ills. The cause and effect ratio is obviously reversed. Its like claiming that playing the violin leads to wealth via some magical process, whereas the reality is only wealthy parents can afford to hire a classical violin tutor for their kid, so sure, the wealthiest neighborhoods have the kids who are the best violin players but it would be pretty clueless to describe violin playing as a vocational skill. Its a luxury skill for people who've already made it, like math is for about 99.9% of the population.

Talking to my kid's friends indirectly and casually, as per above the deck is stacked against them resulting in lower scores in stuff that won't result in a job anyway, no amount of study will improve your DEI scores which are all that matter for hiring anyway, and the jobs you can get with high scores are the ones targeted for elimination via AI.

Despite being pretty young they understand the scam that it doesn't matter if it works or not, the powers that be will ruin your career trying to replace you with AI. Much like outsourcing in their parents and grandparents generation, it literally doesn't matter if it works or not, you're still sitting in the same unemployment line if they make a profit or lose their shirts. They lost their shirts and will lose them again for AI, but that provides little sympathy for those sitting in the unemployment lines.

"Line must go up" meme applies. There exist tests you can make kids take to determine their suitability for labor in the garment industry, fine motor skills, some visuospatial skills, etc. That number is useless because there are few jobs, negative industry growth, and we have a severe supply/demand mismatch already. Increasing "garment industry skill test results" led directly to happy outcomes around the 1850s industrial revolution and flat to negative outcomes in the modern era. So it is with math today. Worship of "line must go up" never made anyone happy or wealthy.

The article somehow avoids all documentation and authorities and instead relies on popular memes and biased "common sense". Its not marked as an editorial, which seems odd.

Are the PISA exams really the ultimate end all, the best goal we have for education?

I like the idea of a standard to measure against, but in my experience, standardized tests are terrible measures of education.

1h agoHN ↗

The whole system is built on the idea that kids will learn because we force them to for their own good. But I don't think you can get real understanding from that, you need internal motivation that comes from a true desire to know more.

I'm not saying lower test scores are good but they might be a sign that we need to move from "push based" forced complete education in childhood to a more "pull based" system. That would mean the only mandatory part is basic skills as opposed to knowledge, things like reading and arithmetic but also critical thinking, social skills, task organization and manual/mechanical work.

Everything else should be optional, fully up to the student (and their parents until they're 18) and available for their whole lifetime. That's the most important part.

If you go to an accounting school and decide to become a plumber after you graduate, then switch to programming at 30 and electrician at 45, you should be able to do that. Low cost, free if you're poor and always without social stigma, the exact same quality and credentials as if you did it in high school.

Sometimes you need to wait and experience life a bit before you understand how important your education is. We should support that instead of making it so you only have one real shot.

If you take the 1998 NAEP 8th grade reading scores by race, re-weight them by the new 2024 demographic makeup of American 8th graders, you will find a predicted point decline of 4.6, rather close to the actual 4 point fall over the period.

Over the same period, reading scores actually improved somewhat for each of the 1998 poorly scoring groups (and quite a bit for Asians), but the poorly scoring groups simply make up so much more of the population now that it drags everything else down.
