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).
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.
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.
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.
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.
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?
A sentence isn't Orwellian just because you are unfamiliar with its terms. I though dynamical systems theory was quite common knowledge among engineers
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?
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?
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.
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?
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.
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.
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.
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.
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
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.
AI, screen time, short form text/video, normalization of recreational drugs, post-truth, there's no one cause but there's lots of things that are not helping
I saw extremely rapid computerisation of my kid's education around 2020. Properly thought out and edited text books were replaced with last minute rushed teachers notes on google docs and buggy apps.
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.
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?
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).
restate in simple language please?
Shit is about to hit the fan.
“ a system can deteriorate slowly even after something fundamental has changed.”: https://chatgpt.com/share/6ab7e7ca-7d54-83ed-931b-55300fa1f4...
So really it is not saying much at all.
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.
Something changed and adjusting is slow

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

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?
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.

Everything is a wave and there are always oscillations.
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?
Holy sentence... George Orwell must be turning in his grave right now.

I think GP's was a reference to Politics and the English Language (1946)—not "1984". An essay against convoluted writing styles.

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.

Yeah that's what I was thinkin, too.

-Education system broken.
-Covid disruptions

I wouldn't know, the articles talking about the loss of learning are paywalled.
Doesn't this just shift the average and calibrate a new set of expectations for the coming youth to placate themselves in an age of all or nothing AI?
Whole word reading has been a disaster.

No, they think they learn, then when they need to use that knowledge it turns out they learned nothing.
Exactly. Calculators didn't make the typical person great at math. They obviated mastery of math.
While kids practice the skills of the 21st century, testing got stuck in the 19 hundreds.

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

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

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.
IQ is not measure of intelligence, it's more like curriculum test if you go into history of test and how it started.
Mind showing a source for IQ declining across the world?

It seems there is no working around learning to write and read properly. We've drifted away from this idea, which might lead to a "soft" dark age.
