Re: Do AI detectors work? Students face false cheating accusations

I’ve been teaching in higher education for 30 years and am soon retiring. I teach math. In every math course there is massive amounts of cheating on everything that is graded that is not proctored in a classroom setting. Locking down browsers and whatnot does not prevent cheating.

The only solution is to require face-to-face proctored exams and not allow students to use technology of any kind while taking the test. But any teacher doing this will end up with no students signing up for their class. The only solution I see is the Higher Learning Commission mandating this for all classes.

But even requiring in person proctored exams is not the full solution. Students are not used to doing the necessary work to learn. They are used to doing the necessary work to pass. And that work is increasingly cheating. It’s a clusterfuck. I have calculus students who don’t know how to work with fractions. If we did truly devise a system that prevents cheating we’ll see that a very high percentage of current college students are not ready to be truly college educated.

K-12 needs to be changed as well.

When I studied physics at Exeter University they still used the tutorial system and finals. Tutorials were held fortnightly; the tutorial groups were typically three or four students.

What about those of us who can explain our ideas and thinking clearly and in great detail in writing but would struggle to even prove we've heard of the topic orally?

I'm not going to sugar coat it and it may sound harsh, but I doubt this is ever truly an issue outside of the minute edge cases.

Yes, there are people who have trouble with public speaking to a debilitating degree, but it would be excessively rare for someone to not at the very least in a one on one with their professor/teacher be able to be so badly affected as to not seem they've even heard of a topic or at least be able to prove they've worked on it to a certain degree.

I would be immediately skeptical of any student who claims they are completely unable to explain their knowledge unless they are allowed to work in complete isolation with nobody to monitor they aren't cheating in some way.

That’s trivially defeated with a recording / transcript.

And we could get an AI to review the recording!

If AI detection cannot be 100% accurate, I do not believe it is an appropriate solution for judging the futures of millions of students and young people. Time to move on. Either from the tech or from the essay format. In either case, we need to change our standards around mastery of subject matter.

What solutions are 100% accurate?

Letting everyone pass.

> mostly the camera sensors Could it be mostly just be..reality? More expensive hardware doesn't somehow make a darker surface reflect more energy in the visible spectrum. "Low light" is not the same condition as "dark surface in well-lit environment." Leaving the visible spectrum is one possible solution, but it's substantially more error-prone and costly. This is still not the same solution as classical CV with "mo…

If you're building a system to proctor students, then part of your job is to get it to work under all reasonable real-world conditions you might encounter: low light, students with standard webcams or just the one built into their laptop, students with darker skin etc. Reality might make this harder for some cases, but solving that is what you are being paid for. Also, this could have been handled much better in the…

The last time I got an ID photo taken, I got to wait and watch as the dark-skinned Indian photographer repeatedly struggled to take a suitable passport photo of the light-skinned white woman who was in line directly ahead of me.

This was at a long-established mall shop that specialized in photography products and services. The same photographer had taken suitable photos of some other people in line ahead of us rather quickly.

The studio area was professional enough, with a backdrop, with dedicated photography lighting, with ample lighting in the shop beyond that, and with an adjustable stool for the subject to sit on.

The camera appeared to be a DSLR with a lens and a lens hood, similar enough to what I've seen professional wedding photographers use. It was initially on a tripod, although the photographer eventually removed it during later attempts.

Despite being in a highly-controlled purpose-built environment, and using photography equipment much better than that of a typical laptop or phone camera, the photographer still couldn't take a suitable photo of this particular woman, despite repeated attempts and adjustments to the camera's settings and to the environment.

Was the photographer "racist"? I would guess not, given the effort he put in, and the frustration he was exhibiting at the lack of success.

Was the camera "racist"? No, obviously not.

Sometimes it can just be difficult to take a suitable photo, even when using higher-end equipment in a rather ideal environment.

It has nothing to do with "racism".

These systems exist in no small part to train that ability, which is crucial to making it in the upper reaches of business and politics. The approach is probably also good for teaching the material, but training in speaking and arguing is more than just a side-effect of it—it’s part of the point.

Lots of elite prep schools in the US use a similar system, for similar reasons.

> Such as? We need an answer now because students are being assessed now. My current best guess, is to hand the student stuff that was written by an LLM, and challenge them to find and correct its mistakes. That's going to be what they do in their careers, unless the LLMs get so good they don't need to, in which case https://xkcd.com/810/ applies. > Personally I think all this is unpredictable and destabilizing.

Effective Acceleration, the promotion of rapid AI development and roll out, appealing to all the deaths and suffering that can be prevented if we have the Singularity a year early.

Extremely optimistic about the benefits of new tech, downplay all the risks, my experience of self-identifying e/acc people has generally been that they assume AI alignment will happen by default or be solved in the marketplace… and specifically where I hope they're wrong, is that many seem to think this is all imminent, as in 3-5 years.

If they're right about everything else then we're all going to have a great time regardless of when it comes, but I don't see human nature being compatible with even just an LLM that can do a genuinely novel PhD's worth of research rather than "merely" explain it or assist with it (impressive though even those much easier targets are).

The part that annoys me is that students apparently have no right to be told why the AI flagged their work. For any process where an computer is allowed to judge people, where should be a rule in place that demands that the algorithm be able explains EXACTLY why it flagged this person. Now this would effectively kill off the current AI powered solution, because they have no way of explaining, or even understanding, w…

> kill off the current AI powered solution, because they have no way of explaining That's not correct. Some solution look at perplexity for specific models, some will look at ngram frequencies, and similar approaches. Almost all of those can produce a heatmap of "what looks suspicious". I wouldn't expect any of the detection systems to be like black boxes relying on LLM over the whole text.

> It is no longer effective to solely use a written essay to measure how deeply a student comprehends a subject. It never was. It's just even more ineffective now that AI exists, than before. The central example of this is college admissions statements. Some kids have the advantage both of parents who can afford to give them the experiences that look good on such an essay (educational trips to Africa, lessons in two…

It is not so black and white though: there is a difference between having your whole essay written by a tutor, or having some things corrected by the tutor, or the tutor giving you general tips that you yourself apply.

Oh, I completely agree. In some cases, discussing a draft with your _university-appointed_ tutor before submitting your final essay is even part of the assignment (I believe Oxford/Cambridge humanities work this way), and a great learning experience, and a way for people who can't afford private tutors to get the same kind of coaching (how you get into this calibre of university in the first place notwithstanding).
