So in theory different students could get different questions? The software I know of that does this is WeBWorK. It will even score student-entered answers for you. See LINK . Supported by the Mathematical Association of America.

As Brandon mentioned in a comment, I'm working to develop an online platform for this use-case, where the banks are generated using SageMath code and PreTeXt XML. Problem sets for linear algebra and differential equations are available to the public at https://checkit.clontz.org/ and I'll be working to add better support for new authors in the near future. ...

For problems that are beyond just calculations, if you can algorithmically create different problems for each student that are similar in difficulty, this may help with the near-guarantee that someone will be posting all of your problems to Chegg. Also, it may be done with any of the problem ideas you list above. Here is an exam question I gave this term, ...

WolframAlpha is not your problem. It really isn't. The students who are cheating by and large aren't good enough to figure out WolframAlpha's syntax and interpret its answers. Your problem is that any of your students can buy a membership to Chegg.com and upload an image of a question. Chegg.com his hired people in less developed countries who will do the ...

I taught all of my classes in an asynchronous (fully online) format this term. Based on ideas posted here, I chose the following routine: Content Delivery: I made videos with my phone and posted them to YouTube for the "lecture" content. I printed copies of activities I wrote, and worked through them in the video, periodicaly asking students to &...

Thoughts: Student can't go back. You have to solve each question to the extent you are able, then move on. If you are unable, you can mark it "return later" But when you return you get a new version of the problem. This effectively eliminates the Chegg problem, as there system has too much latency. This requires submitting your first partial ...

The best technology in those circumstances is the "print" feature of MyOpenMath. Could you have each student print out their copy of the exam, take it on paper, and then have access to the solutions immediately after the time runs out? No internet + randomized questions => probably no cheating [In the "create print version", you can ...

One of the things I'm currently testing is the addition of "find the error" based problems, and possible variations. For example (related but not the same topic) last semester I taught indefinite integrals, so in a partial test I decided to ask my students the following problem: The integral $$\int \dfrac{3-x}{(2+x)^2}~dx$$ can be solved in ...

I hold the opinion that preventing or disincentivizing cheating is practically impossible. If I want to quiz my students about partial fractions or trigonometric integrals or the sorts, I can’t prevent them from putting it into WolframAlpha or the like by just changing the phrasing a bit, because WolframAlpha can solve partial fraction integrals. Instead, I ...

"The problems from which the test is composed , should they be routine, typical ones which mimic the ones in the students’ textbooks? Or new ones which need a lot of thinking and imagination, yet require the same knowledge provided by the text?" I recommend to go with the "routine" questions. (Scare quotes intentional!) (1) Don't ...
