Why not just grade solely based on live performance? (quizzes and tests) Homework would still be assigned as a learning tool, but has no impact on your grade.

Because students wouldn't do the homework and would fail the quizzes. Students need to be pressured into learning and grades for doing the practice are a way. Don't pretend many students are self-motivated enough to follow the lecturer's instructions when there's no grade in it and insisting that "trust me, you won't learn if you don't do it".

  > would fail the quizzes. not those who did actually do the work, and learnt. The change ought to be that students are allowed to be failed, and this should be a form of punishment for those who "cheat".

    Aren't students already allowed to fail? As a comment upthread said, let them cheat on the take home as much as they want to, they're still going to fail the exam.

      Well, from what I understand, the answer is kinda "no". Depends on the country and educational system I suppose, but I do believe professors in many places get in trouble for failing too many students. It's right there in the phrasing. If most students pass and some fail, that's fine. Revenue comes in, graduates are produced, the university is happy. If most students fail, revenue goes down, less students might sign up, less graduate, the university is unhappy. It's a tragedy of the commons situation, because some professors will be happy to pass the majority of students regardless of merit. Then the professors that don't become the problem, there's something wrong with them. Likewise, if most universities are easy and some are really hard, they might not attract students. The US has this whole prestige thing going on, that I haven't seen all that much in other countries. So if the students overall get dumber because they grow up over relying on tools, the correction mechanism is not that they have to work harder once the exam approaches. It's that the exam gets easier.

        For the most part degrees from roughly comparable schools in the same subject are fungible. However, graduating cheaters who should have flunked out of school their freshman year is a one-way ticket to having a reputation that your degree is worthless. You're now comparable to a lower tier of schools and suddenly Y's degree is worth a lot more than yours. The best way (not to only way) to combat this is to actively cull the bottom of your classes. Most schools already do this by kicking out people with low enough GPAs, academic probation, etc. My undergrad would expel you if you had a GPA below 1.8 after your first semester, and you were on academic probation if your GPA was > 1.8 and <=2.5. This assumes, of course, an institution is actively trying to raise the academic bar of its student population. Most schools are emphatically not trying to do this and are focused more on just increasing enrollment, getting more tax dollars, and hiring more administrators.

  I've mostly had non-graded homework in my studies because cheating was always easy. In highschool they might have told your parents if you don't do homework. In university you do what you want. It's never been an issue overall.

  When I was a student, I spent my first 2 years in a so-called prépa intégré of a French engineering school. 20% of students failed and were shown the door during those two years (some failed, some figured that it just wasn't for them). That's fine, that means you keep the ones who actually do the work. At a certain point, you have to start treating students like adult, either they succeed or they don't but it's their personal responsibility.

    That looks bad in the international statistics and so on, there's a lot of pressure to just pass everyone. In Italy university keeps getting easier because their funding is tied to not failing students.

  Many mathematics professors don't require homework to be turned in for grading. For example, the calculus courses at many US universities. Grades are solely determined by quizzes in the discussion section and by exams. Failure rates are above 30%, but that's accepted. This model won't work for subjects that rely on students writing reports. But yes, universities frequently accept that failure rates for some courses will be high, especially for engineering and the sciences.

  My favorite math professor said "your homework is as many of the odd-numbered problems as you feel like you need to do to understand the material" and set a five minute quiz at the start of each lecture which counted as the homework grade. I can't speak for the other students, but I did more homework in his classes than any of the other math classes I took.

  Certainly with maths you’re marked almost totally on written exams, but even if that weren’t true you’re also required to go over example sheets (hard homework questions that don’t form part of the final mark) with a tutor in two-student sessions so it’d be completely obvious if you were relying on AI.

    I really like oral exams on top of regular exams. The teacher can ask questions and dive into specific areas - it'll be obvious who is just using LLMs to answer the questions vs those who use LLMs to tutor them.
    - deepsun 1y ago
      Of course, the reasons they do quizes is to optimize the process (need less tutors/examiners), and to remove bias (any tutor holds biases one way or the other).
  - guappa 1y ago
    In italy there's an oral in most exams. In math exams you're asked proofs of theorems (that were part of the course).

  Funnily enough, the best use of AI in education is to serve as exactly this kind of tutor. This is the future of education.

    The promise of the expansion of this kind of tutorial teaching to everyone via AI is great. The problem is keeping students honest with themselves.

My high school English teacher's book reports were like this. One by one, you come up, hand over your book, and the teacher randomly picks a couple of passages and reads them aloud and asks what had just happened prior and what happens after. Then a couple opinion questions and boom, pass or fail. Fantastic to not write a paper on it; paper writing was a more dedicated topic.

That's exactly how scientific courses were in my experience at a university in the US. Curriculum was centered around a textbook. You were expected to do all end of chapter problems and ask questions if you had difficulty. It wasn't graded. No one checked. You just failed the exam if you didn't.

That's how it is in Italy. And that's why Italy is behind every other country in education. Because it hasn't yet made graduating as easy as it is in other places.
- pc86 1y ago
  Well graduation rate is a pretty terrible way to grade education, especially country to country. You could have 100% graduation rate today by just passing everyone - that's basically what we have in primary education and there was an article here just last week about how most college students are functionally illiterate.

    In sweden until high school it's literally impossible to fail. There's no grades and no way of failing anyone. Then they suddenly become kinda stricter in high school, where your results decide if you can go to university and which. But I've been to one of the top technical universities and compared to Italy it was very easy. It was obvious the goal was to try and have everyone pass. Still people managed to fail or drop out anyway, although not in the dramatic numbers I saw in Italy for math exams.
