I have seen it firsthand in the CS department here at Dartmouth. It is bad. We're currently designing a new intro systems curriculum, and we're thinking of it as an adversarial problem. That is, we're designing the course to ensure that a student optimizing for the best grade per unit work still meets our learning objectives. That means, as everyone else is saying, paper exams, but also 1-on-1 interviews to check that students understand each assignment they turn in. These interviews feature both factual questions ("You're using this macro from that library. What does it do?", "Please describe what this function does and how it works.") and conceptual questions ("Why is this code structured this way instead of $whatever?", "How else did you try solving this?", etc.) This doesn't stop students from generating code, but at least they have to understand that code in detail. This is not as good as writing the code yourself, but how much worse is it? For math classes, this gap is gigantic. Obviously, understanding someone else's proof is much easier than writing your own. For programming classes, I think (without evidence) that the gap is somewhat smaller. My experience from the past is that when this kind of evaluation is made clear up front, the students know what to expect and either do fine or drop the class in the first week. If you start with take-home exams and then spring paper exams on them halfway through the course, then half the class is cheating and won't be able to recover, as we read in the article. In general, our students are somewhat motivated by an abstract desire to learn, but are much more motivated by grades. If there exists a straightforward path through your course that leads to a good grade without doing much work, most students will take it. (Our undergrads' course review website is literally called "Layup List." They are actually this shameless.) It's our job as instructors to ensure that all paths leading to a good grade either require learning the material or are more difficult to pull off than just learning the material. It's best not to blame the students. They are good at optimizing metrics; that's how they ended up here in the first place. We just need to better align the evaluation metrics with the outcomes that we're looking for.

> Obviously, understanding someone else's proof is much easier than writing your own. Unrelated, but once you get to a more mature level, say grad school and above, I can say this is not always the case! Just like it's easier sometimes to Roll Your Own Damn X in programming, so too are some expositions of proof so dense (necessarily or unnecessarily so) that it is a less taxing affair to simply figure it out yourself, or at least figure out 90% of it, consulting a suggestive sentence or two in the proof in order to get at that last 10%. Maybe this observation of mine is not so unrelated after all. I don't regret many of the times that I've thrown up my hands at the rococo explanations or solutions given to me by LLMs and simply did my own work. The Socratic method with AI is sometimes more effort than it's worth.

  Understanding 90-95% of someone else's proof is much easier than writing your own ;) It's hard to verify that you understand someone else's work at 100%, but it's reasonable for an expert to tell once they've built it themselves, right?

  > The Socratic method with AI is sometimes more effort than it's worth. lol, so true. I think the main issue here is that LLMs don't have the ability to produce the terminal "I don't know".

Without a hint of irony, wouldn't a Voice AI solution help better manage the 1-1 interview process?

  1-on-1 interviews with a LLM sounds like it'd go over about as well as AI customer service.

    Do you mean very well? Lots of proof out there that it works; Fin, Sierra and others already operate on a value based pricing model where they only get paid if the AI actually resolves issues.

        A lot of restaurants in Korea and elsewhere have replaced human cashiers with touch screen kiosks. You’re given a number, someone calls it out when your drink’s ready. For the places I went to it worked just fine. Did you have a bad experience?

"best not to blame the students" There are dozens for every one who didn't get the opportunity to attend an Ivy. The penalty for cheating should be automatic expulsion. I'll note as a hiring manager the college degree won't be worth shit unless the school can show their students have any integrity.

  Totally agree. The moral decay in higher education has a lot to do with it deciding to trade its integrity around cheating by students and professors in exchange for tuition cheques and grant money.

  I doubt it. The concept of cheating is largely unique to academia and a few uptight professions like law. Everywhere else it is just collaboration or learning or simply something nobody cares about. I would say that tech largely rewards the behaviours people in academia call cheating.

      when you cheat on your partner you hurt them by betraying their trust. when you score from offside you can steal a win from the other team thats playing fair. if you lie about your company financials you steal from the government or your creditors. cheating in schools is nothing like that. there is no direct harm to anyone, financial or emotional. the only real thing is if enough students do it thats bad for the schools reputation and others will treat degrees coming from there as more suspicious. thats a very abstract and indirect harm, and it depends on employers caring about what school you came from more than a basic "reputable or total scam". to be fair thats pretty common in some industries (it shouldnt be) but i dont think the average student will get worse job offers because some of their classmates cheated.

People optimizing for grades is so sad. I got a BS in CS and no one has ever asked about my grades. I tried to optimize for learning and it turns out that pays off really well once you hit the real world.

  If you want to be a MD or a JD, then you must optimize for grades. The entrance into post secondary education requires it to be so. Seeing as the article was about Brown and their PLME program is famous for med school acceptance, then I think we should expect that the culture there is more about grades than a generic undergrad university's culture. Which, yeah, is also very grade focused.

As an alumnus of Dartmouth College's CS program, I am sad to hear that my alma mater has sunken so low. Look, I know that the Committee on Students was historically bad at handling CS plagiarism cases back in the 90s (compared to ones in the humanities). But Dartmouth's historic solution to this sort of pernicious "optimization" was to reduce the expected value of cheating by imposing extreme negative consequences on anyone they caught, with a 3-term suspension and a permanent transcript notification for a first offense. Allowing widespread cheating and LLM regurgitation will destroy a school's reputation with graduate schools and employers, and rightfully so.

I mean even before AI this should get tested, as people could just copy code from SO or other websites, from books, or from their classmates. I've done a few projects where the other students didn't really do much (in hindsight this was probably because I was excited and productive instead of helping and delegating work, which was selfish of me), but they were caught out in 1:1 interviews.

You reminded me of my Univ. Math's class (on integrals). The test was basically get one integral equation randomly and solve it in the blackboard only with the teacher present. Because you didnt know which type of integral you will.get, we had to learn to solve all of them. We made.hundreds of exercises with a small group of close friends (the teacher gave us a book that's infamous in Mexico from an author Schaumm).
