AI Boosted Homework Scores by 18% – Then Exam Scores Dropped 20%, Study Shows

This article is about the Economist's summary of a journal article so we have a (AI?) summary of a summary. Not very helpful. Here are a couple of better references:

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.

by yoyohello13

8/21/2026 at 5:23:42 PM

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.

by comicjk

8/21/2026 at 5:24:29 PM

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).

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.

Stand-alone bottom-up observations (even if valid) obscure the fundamental problem that AI (or "AI" if you like) is inducing systemic change across human civilization.

If cohorts are graduating into the workforce with decreasing stand-alone skills, that implies the economic value-add of labour is shifting to AI, which implies broadly falling standards of living, falling political power, and an ongoing transfer of power and wealth to capital.

If students are taking shortcuts with AI when their brains have the highest capacity for learning they may be permanently weakening their prospects. It doesn't seem likely that whatever "AI management skills" they incidentally learn will make up for, over their lifetime, the economic value loss they suffer due to reduced cognitive skills.

On an individual basis, in the next few years, this might not matter. Across decades, economies and polities, it will.

Students have been cheating and taking shortcuts on their work long before the current generation of AI tools existed (and probably for as long as graded exams have existed).

Somehow, civilization has managed to survive.

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.

This is the answer. Many (all?) European schools don’t give homework (this is partly because of the way the grad programs work). It’s on the students to study in order to pass the (difficult) exams.

by GPerson

8/21/2026 at 4:48:43 PM

Seems this did effectively abolish homework if AI is now doing it all for them. The result seems to be that fewer students pass the exams, not more.

As with any skill, practice is necessary to achieve competence. If homework is no longer a viable way to force students to practice, you'll need to find some replacement, you can't just abolish it and expect there to be no negative consequences.

by dan_ggggg

Everytime a student says this—it's because they're procrastinating on their work. The hardest part about anything new is starting it. Once you build some momentum, interest and focus tends to build as well.There certainly are some homework assignments that are boring.

A child today can absolutely be successful at doing their homework if they have time to... sit down and write, or draw, or do crafts or things that require them to focus. It's not like Screens exist, therefore no attention span.

What's happening is people are only fixating on screens, and foregoing these slower forms of media. That's akin to saying all children will be obese now that fast food is around. Of course, obesity rates will sky rocket if all you eat is fast food. But if a kid grows up to have homecooked meals, and eat with their parent(s) then they won't. It's as simple as that.

Guess what this is probably fine. AI helps people do their work on a daily basis and probably makes them memorize less things. That’s how the world is moving. You don’t need to be able to memorize something for an exam to show mastery of a topic. And we shouldn’t organize our society around memorizing things for exams.

by grahammccain

What is a doctor? The person recommending next course of action based on best practices. What is the best practice? Is it a globally decided on thing, a locally tested thing that has proven to be better? Is the global thing just the most popular because someone wrote it on reddit and it got millions of views (but isn't actually good).

If our society is organized on just delegating all authority to "the best answer" we can drop all jobs - and only the surgeon has some authority over the machine. When we have a surgery robot, then they can go to. And at some point we'll be recommending and forcing surgery for athletes foot because some kind of best practice or viral post going out of control and a bunch of openclaw bots randomly decide to make tons of recommendations online for amputation for athletes foot and GPT 8.6 agrees this is the way to go.

OR we can somehow decide there is a boundary, there is some room for human memory and decisions.

by throwitaway222

I actually think having a single source of truth would not be terrible. Let me explain.

All podiatrists are not the same. All physicians in their specialties are often specializing in their own niche and are up-to-date on that niche.

I've had lisfranc ligament injury. My podiatrist wanted to perform a surgery quickly, which in 90% of cases is advised. I decided to seek a 2nd opinion because I realized she did the X-rays wrong, as she did them non-weight bearing, which is useless if there are no fractures.

The specialist was excited to see me, and up to date on all the lisfranc research. I've had a really bad sprain and he said conservative treatment should be sufficient. It took months but I healed up.

I've had quite a few injuries from playing sports and often found doctors to be "wrong" simply because their knowledge was out of date.

by avgDev

8/21/2026 at 4:56:38 PM

I am confused as to how this is an argument for a single source of truth. It seems like you've presented an argument for the opposite. If there were a single source of truth, there would be no point in seeking a second opinion - it would be the same as the first. If the first opinion was correct, excellent. But if the first opinion was incorrect (and no AI model is correct 100% of the time), then you're straight out of luck.

by Calavar

8/21/2026 at 5:27:25 PM

The problem is that the first source is incorrect because she doesn't deal with lisfranc injuries frequently enough and her knowledge is not good enough. I've had to go do my own research to find a guy who specializes in lisfranc. Most patients would not.

However, if you went to an AI agent which has access to medical research, you would get the most up to date research.

Why would I seek a 2nd opinion if the initial doctor knew what to do?

by avgDev

8/21/2026 at 4:56:37 PM

> I actually think having a single source of truth would not be terrible.

We should establish a single practice of care, MedicineGPT. It may be a rough start but over time the gene pool will adapt and the human race will live harmoniously with the machines (sorry, with the GPUs). Plus our insurance premiums should finally go down.

Ironically I had a friend who went to med school and in his own words roughly 90% or more of the students there are heavily relying on GPT. They even had a few instances where people were using it to cheat during exams. And supposedly during the clinical years of uni if they don't know something they literally just go to a separate room and start asking GPT for answers. Make of that what you will.

by rfgplk

8/21/2026 at 4:47:46 PM

This is too simplistic. There are disciplines, like Anatomy, where you're basically just memorizing bones, glands, and other parts of the human body. For organic chemistry, students need to memorize most of the krebs cycle diagram for their exams (because doing so and drawing it lets them reference it later).

Thinking is infinitely more complex than "critical thinking" vs. rote functions. You want students to get to critical, eventually, but the lower orders on bloom's taxonomy serve important roles, too.

Course design built around multiple choice questions, essays, and a lot of the historical assessments that we're used to are largely not great for learning in the first place—–they're used because they can be auto-graded or score assigned quickly. AI, conversely, is kind of revealing the limitations of these outmoded learning design practices.

Think of the meme going around right now from Milennials to Gen Z: "I wrote a 5 page essay on a book I never read!" <- They're saying this to AI generated essays as if there's any difference in the critical thinking that comes out of an exercise like that (read: absolutely none).

AI is a new tech—so of course people are still figuring out the limits of it. In 10 years a lot of the paradigm will be set. Until then, students are unfortunately kind of in the thick of it.

by spandrew

8/21/2026 at 4:49:17 PM

How do you differentiate between mastery of a topic and mastery of using an AI in an exam setting?

Open book tests and allowed cheat sheets already solve the memorization-is-not-required gap. It seems like allowing use of AI pushes that closer to thinking-is-not-required. And if no thinking is required, then how can you prove personal mastery?

A lot of expertise is actually knowing things about the domain. You can't make a good judgement call on a topic without getting relevant knowledge in your head to make that decision. You can't even lookup the relevant knowledge without knowing what knowledge is important to make the decision, so reference material is not enough.

Memorizing stuff is good for understanding. Of course memorizing without understanding doesn't really help, which is what a lot of student last-minute "cramming" boils down to. But without concrete and memorized knowledge, any abstract reasoning skills become quickly impossible.

by gampleman

8/21/2026 at 5:04:09 PM

Wrong. Memorizing without understanding is pointless. And I'd argue that rote memorization does nothing to guide ones understanding. Because if you actually understand a subject deeply enough you can literally derive almost anything that would need to be memorized on the fly, and if you can't (say constants, or spec information, or anything else) you can simply surgically look it up online (or via an LLM).

by rfgplk

8/21/2026 at 5:22:04 PM

> Wrong. Memorizing without understanding is pointless.

GP said exactly the same thing.

I agree with GP’s broader point, which is that you cannot have understanding without a specific set of baseline facts. The student studying only those facts and never achieving the understanding they are meant to support is a tragedy of our education system.

There are people who need to understand microbiology at a specific level and they cannot derive it all on the fly. They can achieve better memorization through understanding but I personally have found rote memorization can be an essential first step in some disciplines.

by jeremyjh

by bigstrat2003

It's critical to understand the fundamentals on your own and that is different from AI being used in public. Sure school doesn't have as much value as it used to but it was always more about social credit or a certification that you took the time and effort to understand the world under pressure (obviously not true for all disciplines) or goals attached preferably in group settings.

This is something that AI cannot replace. Viewing things as memorizing is the wrong take.

8/21/2026 at 4:07:41 PM

These are students aged 12-18. Even if we ignore all the other negative externalities of AI and assume it will be ubiquitous and cheap, kids need repetition and exercises to make inferences and develop intuition.

Sure - you can ask AI to, for instance, calculate how much money you'll have given a fixed principal and a compounding interest rate. But we need to get a kid to the point where they even understand what the question to be answered is. If they're using AI all along the way, they are developing less understanding of what fractions and exponential growth are.

Will it stop the really smart and motivated kids? Of course not. But at population scale there will be big consequences.

by antonyt

8/21/2026 at 4:11:01 PM

The important thing is that I could learn to use a flint and steel pretty easily if I wanted to. I don't need to carry out that particular task, but my ability to adapt to new problems means I can carry out more relevant tasks when needed. The most useful part of school and university for me wasn't that I learned the difference between a cirrocumulus and a cirrostratus cloud in geography class. It's that I learned how to learn.

If we let children cheat their way through school and justify it by saying they don't really need to think for themselves anymore, then we're going to end up with a generation of adults who struggle to take on any difficult tasks at all. I suppose your counter-argument to that will be "but we can just hand over everything to the AI" but that's an essentially an argument that humans should be considered obsolete altogether. I sincerely hope that that's not a path we end up going down (although I'm genuinely scared that it is).

1) We're building a tool that can make toil of all kinds obsolete. We're not there yet, but I'm watching it happen in real time.

2) The fact that it works so well economically means that it's inevitably going to take over. Humans simply won't be profitably employable, and this will happen sooner than you think.

3) The takeover could lead to a utopia, where nothing is needed of anyone, and you could do what you want when you want it.

4) Humans are likely fuck that up, and it's worth doing what you can to end up in the group that benefits. Sipping wine on the beach isn't mutually exclusive with a great deal going to the winners.

I do not believe that human brains are magical, and I think that they can be surpassed with manufactured brains.

Concerns over equitable the distribution is doesn't affect the value of the skills.

I get it, there's a strong anti-AI vibe here because of point 4. I'm somewhat worried, but I'm also really excited about the possiblilities, and I don't think we can avoid going to that future regardless.
