The kids who used AI and studied for a similar amount of time as the non-AI high performers apparently had similar (slightly higher) performance. The kids who used AI and did poorly used the AI to do the homework for them (this is what the article says).

I believe AI is basically an amplifier of bad and good. I’m cynical about the world and assume it will be used more for bad than good, but I don’t doubt some of the best people in every field will be using AI to amplify their work in good ways.

This is kind of damning, isn't it? "Similar or slightly higher" for spending the _same time_ means it's not, in fact, helping. At the same time as being extremely damaging to a significant number of students who, of course, use the AI to cheat. Because everything about it makes cheating easy.

It's not so clear that AI is an amplifier.. The paper has some fascinating analysis on this topic:

"At the other end of the distribution, AI students who spend more than 65 minutes on their homework receive homework and exam scores similar to those of non-AI students, suggesting that these students do not use generative AI for homework assignments. However, this group consists entirely of students who adopted generative AI no more than Öve months. Six months after adoption, no AI student spends more than 65 minutes completing their homework (see Figure A5). This is consistent with the gradual process of learning how to use AI tools. It also suggests that AI crowds out the highest level of e§ort."

"Interestingly, in the range of 50-65 minutes, the median and the interquartile range of exam scores of AI and non-AI students are similar. This implies that, in the range where AI students and non-AI students have overlapping homework times, students who spend the same amount of time completing homework on average receive similar exam scores."

"This pattern shows that students who spend the same amount of time on homework learn similarly, with or without generative AI. In other words, generative AI reduces time spent learning for the majority of AI students but not learning efficiency for those who spend the same time studying as the non-AI students."

Depends who's using it. Like many tools the force multiplier depends on the operator.

I'm confident it's an amplifier for people who know how learning works and already do a lot of it, successfully. However the level of "learning fluency" I'm talking about isn't reached for many until late college or grad school, and sometimes not at all. So I'm not surprised by the quoted results for 12-18 year olds.

It would be good to see the effect of access to AI during preparation on those who previously achieved top 10% points in exams of similar topics before. I suspect they would benefit further.
kzz102 38 minutes ago||
My apologies for coming off as over-enthusiastic, I am currently obsessed with this study. Here is another quote:

"The negative learning effects are larger for students with higher initial achievement. The differences in the estimated full (6-10 month average) effects are substantial, with a 50% gap between the most negative effect (-24 percent) for the highest tercile and the least negative (-16 percent) for the lowest tercile. "

Not top 10% as you asked, but the closest to what you asked. My working hypothesis is that top performance is highly correlated with willingness to work hard, and AI decreases the motivation to work hard.

bonoboTP 24 minutes ago||
Interesting. Top academic performance is mostly correlated with conscientiousness (willingness to work hard and keeping track of things) and intelligence. And I'd add motivation and interest to that too.

I think if you take a physics class where the student is intelligent and intrinsically motivated through their own interest (I admit this is rare) then AI probably helps.

well most university exams are designed to measure how much you study. so we didn't really need a study to tell us, "Exams continue to measure what they are designed to measure."

they're not designed to measure general aptitude, or function as admissions criteria, or screen for job applications, or any other numerous things they are used for.

there can be many questions of pedagogy. one of them is, what do our exams measure and how do we use them? professors who say, "My exam is designed to measure who studies, not be used for all these other purposes that they are actually used for" - I don't buy it. It's the same as late night comedians saying they are not responsible for solutions, even when spending 90% of their air time making political jokes.

THIS is the pedagogical issue, that pedagogy has NEVER caught up with the scope of responsibilities. This is acute in STEM - I mean, the humanities departments are generally pretty well run, all things considered, in this regard. Generative AI is accelerating that pre-existing crisis.

kzz102 48 minutes ago|||
The fact that exam scores are correlated with how much you study is not the same as exams only reflect how much you study. Two students who study the same amount could have very different exam scores. The reason that there still is a strong correlation between exam score and time of study is because if all other things being equal, students who studies more have higher exam scores.

at least in my experience in university - i didn't really ask this question, since it is obvious to me, but some students have asked it during lecture, or some instructors have volunteered the answer ahead of time - if you ask how to perform better on the exam, usually the instructors say, "here's what you should study." they never say, "know more." the thing i am talking about is consistent with the paper. really, your takeaway should be, exams can't see how much you know!
bonoboTP 43 minutes ago|||
Because "know more" isn't actionable. Knowing more is achieved by studying but not necessarily more time spent studying, but well spent effort. Staring at the page for hours and saying "I don't understand" doesn't help. Solve exercise problems, explain the material to fellow students, discuss it with them, make mind maps, bullet point summaries, work through derivations step by step, etc. There are many techniques.

At the end of the day though what matters is what you know. Furthermore, if it's a serious subject, it shouldn't matter whether you learned it from this teacher or from another school and teacher, as long as your knowledge is correct. Knowing the idiosyncracies of this particular teacher should not factor into the grade. A serious subject can be learned on one continent and examined on another. Bullshit courses are all about learning pet peeves and hobby horses of a particular teacher.

The scary thing is that 81% of AI users in this study were determined to be "outsourcing" their homework to the LLMs - and the rate increases the more exposure they had to LLMs.

The "slightly higher" performance is based on statistically insignificant samples (between 4 and 20 students, depending on the context, out of the total population of 26,000): https://bsky.app/profile/benjaminjriley.bsky.social/post/3mt...

I thought that it was generally accepted by now that homework in the volumes that it is being assigned in the modern day was not found to be beneficial in any significant way in the first place? Maybe once all students start outsourcing it to AI it might finally die like it deserves to. People these days grow up with almost no free time for themselves, it's all school, sports/extracurriculars or homework nonstop. All worker drone and no play makes for an increasingly dysfunctional society.

How do you expect students to learn anything when:

1. They don't do any homework.

2. All the in-class time is split between the teacher babysitting and playing social worker to problem students, and lecturing, with little to no opportunity to actually practice what they've learned?

I understand that some students don't have home environments that are conductive to doing homework well. I understand that some students are enrolled in five hours a day of extracurricular university-application-padding activities. I understand that some students have incredibly poor screen discipline and impulse control.

But I don't understand that anyone has magically figured out how to teach complicated things to students, and have it stick without them spending a lot of time practicing what they are learning.

As anyone who has tried to do something hard knows, the first step to being good at something is to spend a lot of time being pretty shit at it.

A student who has written and received feedback on 500,000 written words is going to be way better at writing than that same student who wrote 50,000, just like someone who has put 5,000 hours of focused practice into playing the piano is going to be better than my dumb ass, who has only put 100 hours in.

(If you found the solution to get good at stuff without practicing it, I'd love to get good at piano without putting any homework in on it.)

BrenBarn 2 hours ago|||
The dangerous thing about amplifying is that bad people are often more willing to amplify their activities, because they don't care about the negative effects. We are seeing this now as AI companies (and large companies of all kinds) rush to secure whatever advantages they can, regardless of the negative externalities. Meanwhile people who actually care about doing the right thing get trampled.

We need to shift the incentives by adding ruinous penalties for things that are currently quite commonplace if they are done by large players. Some dude training his own AI on his own computer can scrape and train. The fine for OpenAI or Meta using a single copyrighted book without permission should be in the tens or hundreds of millions.

What we're seeing currently in our society is a "loophole inversion" where the rules have an effect mainly via their loopholes. The most profitable activity is to find loopholes and exploit them as frenetically as possible to gain as much advantage as you can before the loophole is closed, or get people hooked on the loophole so it's retroactively legalized. Entities that are big enough to do this are big enough because they have lots of money behind them. Entities doing the same kinds of things without lots of money are not really doing much harm. So the best approach is to adopt a "sliding scale" in which even tiny violations by wealthy actors result in penalties enormously greater than fairly large violations by small players.

There is zero evidence for this.

LLMs make significant mistakes frequently and smart people have no way of judging those mistakes outside their domain expertise. They are also sycophantic and great at being an echo chamber which makes people feel smart even if they are not.

So I think the burden of proof is on you to prove that they somehow amplify intelligence, it seems highly unlikely.

Most domains have some kind of internal consistency/theory building you can do. A smart person can certainly notice inconsistencies when trying to learn something.

> Raising the noise floor like this only makes it that much harder to find "Smart" people,

It does give us a new heuristic, though: people who are willing to completely cut generative AI out of their lives (cold-turkey, if you ever started using it) are a much smaller group of, predominantly thoughtful, people. You do have to give up Claude to be part of this group, but from what you say, that's no great loss, and no longer being deafened is worth it.

This has considerable advantages over conventional elitism, because the barrier-to-entry is negative in almost all cases.

The one exception I've found is assistive tech, where the state-of-the-art is so poor that vibecoded slop is genuinely an improvement over the state-of-the-art, and in many cases the tooling simply isn't available to make your own assistive tech (unless you want to bootstrap an entire networked computing environment, which isn't very helpful when you want to do your online banking and do not, in fact, work at your bank).

But there are not many principled exceptions where you could seriously argue that the trade-off is worth it. Take mathematics, for example, which we often see touted as a "good use-case" of generative AI. The primary advantage of generative AI in mathematics is being able to search though a vast corpus of ivory towers and inconsistent terminology (without proper attribution) to locate and connect ideas that can help solve problems. The deficiency this is addressing is elitism, inadequate communication, and inadequate indexing within academic mathematics. This problem is entirely created by the academic mathematicians, and has been known for nearly a century (per https://en.wikipedia.org/w/index.php?title=Nicolas_Bourbaki&...):

> Bourbaki was founded in response to the effects of the First World War which caused the death of a generation of French mathematicians; as a result, young university instructors were forced to use dated texts. While teaching at the University of Strasbourg, Henri Cartan complained to his colleague André Weil of the inadequacy of available course material, which prompted Weil to propose a meeting with others in Paris to collectively write a modern analysis textbook.

To my knowledge, this is the only organised project to clean up and improve mathematical communication. Everything else (Metamath, Mizar, AFP, Lean) is yet another ivory tower. The Wikipedia article on this topic (https://en.wikipedia.org/wiki/Mathematical_knowledge_managem...) risks deletion as non-notable, that's how little anyone's actually trying. They made their own bed, and generative AI will only provide a brief respite from having to lie in it. (I was surprised how many other "compelling" use-cases evaporated when I applied this razor to them: the sibling comment https://news.ycombinator.com/item?id=49392265 points out one such.)

Vibe-coding assistive tech which doesn't yet exist, as a temporary scaffold to improve the quality-of-life of yourself and others in a social world dominated by non-essential access barriers is, to my knowledge, the only exception to this principle that can be justified. If you treat people who make other excuses, or who don't even bother with excuses, as not worth listening to, you lose little – and doubly-so, if you make your stance clear, so that others know the "cost" of gaining your attention.

All AI did here is exposed an old problem in education. Kids are expected to get everything perfectly for the first time but a lot of them don't so the class gets easier next year to keep up pass rates.

We need to restructure the system to treat failure as a signal instead of a disaster. Grades should come from hard randomized exams with unlimited retakes so one bad day won't hurt you. Homework should be optional material for self study, evaluated by teachers if you choose to do it but never forced.

Hold back students for individual classes instead of a whole grade so failing one can't ruin your social life and teachers are more willing to do it. F students will realize they have to study, start actually learning and then pass on the second time. No big deal. It happened to my friends in college, no reason they can't do it in high schools.

Discipline is a skill and it's one you have to get from experience. If you try and force kids to study when they don't want to "for their own good" you're not actually helping them. Everyone needs to find their own path. Let people fail.

> Homework should be optional material for self study

At Caltech, homework was assigned but had no bearing on your grade. The grades were based on the midterm and final exams.

But not mastering the homework usually resulted in flunking the exams. There were "retch" sessions after each homework assignment that was staffed by a grad student, and the purpose was to help the students understand the homework problems. I knew only one person (Hal Finney) who was so smart he didn't need to do the homework.

I learned the hard way that the path to success was:

1. never miss a lecture, no matter what

2. take notes by hand during lecture

3. do the homework on time, and make sure you understand every problem. Take advantage of the retch sessions.

And that worked for me.

CobaltFire 47 minutes ago|||
Naval Nuclear Power School had (maybe still does) this model 20 years ago as well. Pass rate for my class cohort was 28% over the entire 2 year pipeline.

We didn't call them retch sessions, and they were taught by the instructors though. We also were encouraged to peer tutor and since we were all restricted to one building the homework was always group work allowed.

Also had badges to track time spent in the building for required study hours, though some people gave up and just slept at their desks when they started sliding down the grade scale and the hours racked up.

Generally I think I did 30 hours of studying/homework (went up and down depending on what was being taught, but was around that) a week (for 12-15 hours of actual lecturing), with some of my friends putting in 50% more. Generally the only day we weren't there was Saturdays. Most of the day Sunday was usually spent in class preparing for the next week.

WalterBright 1 hour ago||||
I've given this advice many times, and the ones who followed it did well. I only added "leave your laptop in your dorm room" for modern times.

The general pattern at Caltech was 2 hours of study for every hour of lecture. Which was quite a shock to me.

nrr 51 minutes ago||
I'll add one more thing to this, given that my experience as a math major at SIU was that each hour of lecture was expected to carry four hours of studying: read and summarize the course's texts (additionally, for math courses, attempt the problems) before lecture.

I found that (1) I didn't need to take anywhere near as many notes during lecture and (2) I could ask way, way, way more relevant questions.

This also helped tremendously when it came to studying for the actuarial exams.

moffkalast 1 hour ago||||
That only works with competent lecturers. I can speak for my experience at a more mid university, where that would apply to about two thirds of the classes. For the remaining third, going to the lectures felt genuinely counterproductive and you could actually feel yourself losing braincells listening to the confused nonsense or classes held in English for Erasmus students by someone who could barely speak it coherently. It was just a complete waste of already little available time.

So the endgame was figuring out what the tests in previous years looked like (cause it was likely gonna be a copy paste affair), do a targeted study run for those exercises and 9/10 you would pass.

As a student of a top-tier French Master's degree, I consulted with a teacher to deal with exhaustion and to ask for a class rescheduling for my case. Explaining my situation, the teacher looks at me and interjected:

—Waitwaitwait. You... you went to all lectures!?

And he was right. Rather than following the curriculum, I should have developed my taste for various engineering topics and only used the classes as entertainment.

I think the first semester, or at least half of that, you should go to every lecture until you develop taste for what's useful.

do you have any evidence that CalTech's pedagogy is immune to today's threats and trends in education everywhere else? (no)
WalterBright 1 hour ago||
Nope.

When I was there, a long time ago, exams were timed and were usually open book open note. Blue books were filled in. You were trusted to adhere by those rules, and most students did their exams in their dorm rooms.

The evidence that the students honored the rules was some exams resulted in a 50% failure rate.

As for me, I went there because I wanted to learn the material. I did not care about getting a diploma. (Mine is in the basement somewhere.) I did not take any "easy A" classes, because I wanted a return on my time and tuition investment. (Though, easy A classes were hard to find at Caltech.) I wasn't even going to attend graduation, but my parents showed up and I attended to please them.

The classes, year by year, were dependent on mastering the previous year's classes. So if you cheat with AI, you're digging yourself into a bigger and bigger hole. Caltech rewires your brain. If you don't learn the stuff, you're going to be one of those EEs who carries around a card with V=A*R, V/A=R, V/R=A printed on it.

Unlimited retakes would be an enormous amount of work for professors/TAs/teachers.

Optional homework is often a disaster. At best, students would do it right before an exam and the goal of education is not to just pass exams. They’d probably still get a lower score than if they did the homework when they were supposed to.

What I think is better is to have a due date, but just make the maximum 10% each day it is late. So after 2 days, the highest score you could receive would be 80%.

I liked that system because it gave some flexibility with deadlines while still encouraging you to turn things in on time.

The study was done in China, where making the class easier to improve pass rates isn't really a thing, as the Gaokao operates more like a stack ranking where it doesn't matter much how well you did in an absolute sense, only that not too many others who did better than you are competing for the same spot. Unlimited retakes are possible in theory, except each costs you a year of your life and except for some extreme cases of repeat test-takers, most people are going to give up after just one or two bad results. Homework is definitely not optional, but going home from school is. (Due to the hukou system, children often have to go to school far from where their parents work, so boarding schools with teacher-supervised self-study are common.) I don't see how holding back for individual classes is supposed to work considering scheduling conflicts.

It's all cute but naively glances over what this all boils to - competition.

Education system, contrary to popular belief/name, isn't tailored to educate but to select winners and losers which then will be picked on the job market.

That's why it seems absurd when you think about it as an institution that aims to educate. That's because that isn't the real purpose of it. The purpose is to stratify and classify early.

Schools do not operate in a vacuum; they serve as credentialing gatekeepers for a hyper-competitive capitalist job market. If everyone could easily retake exams until they got an A, grades would lose their primary utility for employers and universities: differentiation. Society relies on schools to provide a neat hierarchy of candidates that for one reason or another thrived in difficult environment of adolescent schooling.

The system often prioritizes compliance, endurance of boredom, and social maneuvering over actual critical thinking precisely because those traits align with corporate hierarchies.

Moneyshot: "The results are eye-opening. After six months, pupils using ai saw their average homework score rise by 18% across all subjects. The time they took to complete each assignment fell from an average of 64 minutes to 45. But come exam time, the same students scored 20% below their classmates who had not called on ai’s help. Homework scores once predicted exam performance; now those who score highest are, perversely, more likely to do worse in exams."

Study design: "David Stromberg of Stockholm University and Victor Lei and Wu Yanhui of the University of Hong Kong set out to fill the gap. They tracked 27,000 pupils aged 12-18 in China, where ai adoption has been fast. Around 80% reported using models such as Doubao and DeepSeek; the other 20% formed the control group."

That said, I think smart use of AI could help.

Kids are, by and large, lazy however. Hell, adults are lazy, this isn't even an indictment on kids or even people in general, I think our bodies & brains are simply wired to seek the path of least resistance from an evolutionary POV.

Kids won't be using LLM tooling as a personal tutor following some sort of Socratic method, they'll ask it to solve their home/coursework for them and blindly copy/paste the answer. Hell, they'll just manually copy down what's on their screen if copy/pasting isn't possible for whatever reason.

Obviously exceptions exist, but I'd wager from being an ex-kid myself the type of kid who would genuinely use these tools for actual proper self-tutoring would be an extreme rarity.

For some of the classes my kids were in, the lessons and homework time were reversed.

Learning the material (using the text book and videos) was what they had to do at night and class time was spent working through problems or applying the material in some way.

Flipped classroom was a popular method when I was teaching math. Some students found it very helpful. The trouble was getting the students to do the reading before class. If students came in unprepared they struggled to keep up.

I did this for the last college programming course I taught (2025) as an anti-LLM measure. Every class started with a very short closed-book auto-graded multiple-choice test on the reading. I was careful to specify which was the core reading needed to learn the material (on the quiz) and which was extra (not on the quiz - I think many professors assign this extra reading to everyone, thinking of their strongest students). I think this developed an expectation in the students that doing the reading was easier than finding a way not to.

It's especially hard when multiple subjects try to do it, because it can add enormous amounts of home-time expectations. And many families can't dedicate that much time.

I do like it though, and I like that college generally leaned that way more (and was better balanced, as it had substantially less time in classrooms, so you could study during the day).

I taught a flipped classroom online. Students had to successful pass a quiz on the before class materials to get the join link to the session.

Popular yes; based on good quality research… no, not really. It’s really pretty unfortunate timing with the AI boom, because the field of education research is not very high on the science quality totem pole. And the field as a whole was and is also slow to incorporate neuroscience findings, too.

This is typical at the college/university level - when I attended 20-25 years ago, we were expected to learn the material through readings outside of class, and then class time was spent on discussion, application, questions, and working through problems.

IMHO there's a lot to recommend this style. A lot of students learn better when they can wrestle with the material at their own pace, on their own time, in their own setting. It quells a lot of anxiety about "I'm not following what the teacher is saying, am I stuped, will I look bad in front of all my peers?" And then class time can be spent identifying holes in your knowledge and getting instant feedback from an expert, which is where they are most useful.

Although obvious, I think it's worth stating that this method mostly (only?) makes sense for higher education, where students are conscious, involved and engaged in their curriculum.
nostrademons 21 minutes ago||
I think it makes sense as soon as students have the fundamentals down. You have to be able to read, listen, make connections, think critically, devote sustained attention to a task, and manage your time effectively. Some students develop these skills in elementary school, and then starting in middle school, the flipped classroom approach can work. Some adults never develop these skills. Although arguably, people that never develop these skills will likely be sitting there zoning out in a traditional classroom lecture and not actually learn anything.

What do you think about it? I think that the ability to study by yourself is probably the most valuable thing one could get from school and most kids usually don't. Your setup would suggest that demanding that a kids know how to study by themselves is going mainstream...?

Your answer - middle school - I find it extremely young for this, which is extra interesting.

IMHO, my kid was assigned way too much homework. One year I eventually told her to do some amount per class (I think it was 45 minutes) and then be done with it so that she would have time for sports and family stuff. She was spending 4 or 5 hours every night on homework and this was in 4th grade.

That year I sent an email to her teacher to let them know that I'm the one responsible for her not doing all the work and if that's a problem, we need to talk. It wasn't a problem.

The one class that was flipped was a relief because she could breeze through the lesson much faster than would normally be spent on it in class and the amount of time on exercises was limited to the class time slot.

If you structure learning in such a way that makes learning just a means to some end, and overindex on that end being the ultimate goal, that's what you get.

This is a pedagogical problem that AI merely exposed. Educators need to figure out How to make students choose the scenic route instead of having them optimize for the most efficient completion of a task.

School has always been about creating compliant workers, not educating people. They will double down on "performing the right things" and "morals" while the economy will continue on its K shaped path as AI gets more capable.

Yea, also the programs are too different. My psychology bachelor felt like a tea party. My computer science master was 60 hours per week during the hardest courses (which were supposed to go for 20 hours per week - so I could only do one course if it was at this level). My game design master felt more like we were dumped into an art school masquerading as a psychology/CS master but it really was art school. My information science bachelor felt like the only "normal" study program.

All of this was at university of which 3 of them were at the same university.

Especially the artsy game design program definitely did not feel like it was preparing me to be a cog in some giant corporate wheel.

Education sustem is not about the actual knowledge, but about training various aspects of the brain during kids development. So even memorizing literature have benefits, even though it doesn't bring any career use.

If you skip this, well your brain won't develop as much at period of life it's able to do so.

I see this as a memorize-vs-understand fallacy many repeat.

It is really a combination: you need to memorize a large corpus of information to operationalize knowledge — understanding a bunch of theorems in mathematics does not help much (even if you are able to prove them when you see them) if you can't remember the boundary conditions they hold under.

Or having good understanding of foreign language grammar won't help you if you do not memorize words that you need to express your thoughts.

Good literature will show you some of life's challenges and potentially let you think through them in a non-stressful situation (other than "I've got to finish the last 200 pages by Monday" ;)).

> if you can't remember the boundary conditions they hold under.

At the outskirts of one's knowledge this is inevitably the case. My impression it is still useful to know that a certain implication is possible - and one can look up the exact conditions.

Maybe. As the nature of assistive tools changes, so does pedagogy. Calculators are the easy example since most of us are (still) familiar. But there are others that were just as pronounced -- e.g. log tables and slide rules were transformational and instrumental at one time, and you've (probably) never used them. If you had used slide rules to solve your homework problems then were excluded from using them on exams, you'd see a similar effect.

AI is a big change; pedagogy is going to change too.

> As the nature of assistive tools changes

I mean, does it? The way I see it, the best LLMs have to offer is infinite patience (until they inevitably and unpredictably start to confabulate, which should be a gigantic red flag, anyhow), I don't see how LLMs can be used to explore teaching paradigms that haven't been explored before. We know pretty well from centuries of empirical experimentation how children's brains develop under different stimuli. It's not exactly something the software industry needed to "hack".

To extend this analogy:

Using the forklift as a spotter and to assist in loading weights increased gains. Then again, a human can do all those things, and provide real human connection.

Meetings are still like exams, if you can't craft a line of thinking on the spot it doesn't come off well.

You don't need a final answer but you can't just answer "I don't know" otherwise you risk being slimed (shout out to anyone who still remembers "You Can't Do That on Television")

Your career is more akin to the totality of school than it is to any specific facet of it imo.

> The social aspects are more important than the exam sitting most of the time.

To spell it out more clearly: every single aspect of your career is an exam. The interview is an exam, quite literally. The day-to-day responsibilities (meetings, planning, problem-solving, collaborating) are parts of the exam. If you're failing at those or automating them away, then what is your role? The assignments (solve X bug or add Y feature) are parts of the exam too. Failing to do these things will mean that, yes, you are failing the exam.

It is stopping some of the adults I work with from learning.

In the case of some management, is causing them to unlearn, forgetting about proper review and maintenance practices.
