"take home, closed book" This is a trap. I understand they've done this in the past, but profs are paranoid now. I don't believe he's 100% correct on each incident of fraud and he's going to ruin students [academic] lives because of it.

lol okay. Why else do you, after acing a midterm, then not even come to the final once it's been announced that you can't use your previous cheating method?

In the AI era, tests are going to have to be in person and hand written. I have written an article on how I have adjusted my classes to the situation: https://htmx.org/essays/universities-and-ai/ Ironically, I think the AI era may make university degrees a better signal of the intellectual abilities of students due to the presence of pre-computer infrastructure like large lecture halls, industrial-scale copiers, etc.

It's news to me that they weren't already. My exams were all in person and on paper in the early 2020s, and even my physics homework was a "do it on engineering paper and drop it in a mail slot" affair. The professors would forbid computers and phones during lectures and would stop to shame anyone who thought they were being sneaky.

Computer Science classes were all on paper for exams, and low level ones did the old "here's a Javadoc, write some code with a pencil."

The only online exams I had were for 100 level electives.

> In the AI era, tests are going to have to be in person and hand written. Forcing hand written should really not be necessary. It would be very cheap in terms of old computing hardware to set up a test room with old desktop PCs that have wired only NICs (with a network connection that goes to a switch in the same room with no uplink, connected to a decent size laser printer only), running something like lubuntu and…

how do you make sure they are not using their mobile phone with llms while the exam? I have seen that happening.

The same method that any test given in the last 150 years has done to prevent people from using cheat sheets or similar, by having roaming proctors in the room? Or policies like certain models of HP or TI graphing calculator only allowed on the table, for the sort of test that requires one...

The problem isn't AI, it's that you gave a take-home exam expected no one to cheat.

AI enables a completely different level of cheating than any prior method. It’s more accessible, better at cheating, faster

For real. Sneaking peeks at the textbook is "good" cheating, in that you're still doing a form of learning. Having LLM write your paper is just a waste of everyone's time.

These days pretty sure computers are cheaper than typewriters.

Computers good enough to run libreoffice writer or the equivalent and print to a networked laser are thrown in the ewaste trash all the time , the cost really would be in the labor and somewhat custom software setup. Could also reuse old flat panel displays that have been decommissioned from office use.

Lubing typewriters and ensuring they have a fresh ribbon also sounds pretty labor intensive.

(Where do you even get ribbons these days)

Can you fit a decent LLM on a thumbdrive?

It can fit on augmented reality glasses, eventually.

Pretty sure that augmented reality glasses, and things in the category of the meta glasses with built-in camera are already banned in most academic test environments, by a blanket policy prohibiting the use of any camera in the room.

Being hand written would be silly theatre that excludes perfectly capable people (like me) who cannot sustain writing more than a few minutes. Edit: I think we’re actually all agreeing. That a typed exam as an option is perfectly cromulent. I’m just saying the idea that it must be written is silly.

Gen Xer here: we coped with hand written exams just fine. Accommodations (extra time and/or a scribe) were available for those who needed them.

We have a testing center set up for people who require accommodations, another piece of legacy functionality I never expected to use back when I gave my tests online.

There should be no computer at all just give students a typewriter. It could prompt a resurgence of the typewriter :)

These days pretty sure computers are cheaper than typewriters.

You can get a manual typewriter (hammer rather than ball) on Amazon for about $200. Brand name ones run in the $300 - $400 range.

"This year, the economist decided that both the midterm and the final exams for his course would be of the take-home, closed-book type (there is a certain tradition of this at Ivy League schools). “It’s a very nice kind of exam, because as you’re giving students practically unlimited time to complete it, it lets you make it harder than normal, to see how far they can go.”

...

"But it also hurts him that the one time in 34 years that he decided to offer a take-home exam, for highly justified reasons, the response was wide-scale fraud."

-----------------

Not to in any way defend or condone academic misconduct, the fact that this was his teaching-career-first take-home exam is probably relevant. Take home exams can be fiendish. I remember having one in grad school where we were given a very insufficient 36 hours to complete it, and many people just didn't sleep. That was from a prof who knew what he was doing. This guy may have accidentally made his exam absolutely sadistic.

Couple this with the fact that students often have other exams they need to be studying for in the same time window. The pressure can be immense. The temptation to use AI to help is going to be hard for many to resist unless the penalties are severe and strictly enforced.

AI cheating is probably going to be a problem going forward in all situations, but open-book, take-home tests are going to bring it out more strongly than other test formats.
