May 9, 2020 at 7:17 comment added ProfRob I don't set tests which are of the form: "Integrate this function" @JamesSCook and I don't use questions I've found on the internet, since usually the solution is to be found too. Setting questions by reference to pictures/graphs is a good way of making it less easy to get internet assistance.
May 9, 2020 at 3:09 comment added James S. Cook I should add, I still think this is way way better than using something publisher produced for testing. That sort of test is even more likely to be ready to look up on Course Hero or that other "study" stie Chegg or Quizlet. Unless the test is newly written and the solution is handwritten and scanned it is hard to stop the gaming of the system. Even in the handwritten case, the absence of proctoring by humans opens wide the door for cheating. The solution is simple, it just involves some good old human interaction and a modicum of integrity on the part of all involved.
May 9, 2020 at 0:23 comment added Willie Wong To second @JamesS.Cook's comment: we teach calculus out of Stewart, which has a quaint definition for the inverse secant function. (He did it so that its derivative would carry no absolute value sign.) If you tell any of the standard CAS to integrate what Stewart considers as the derivative of the inverse secant function, they will invariably come up with something else. To cut the story short: we have fairly strong evidence that statistically 20-35% of our students cheat on the online exam.
Mar 25, 2020 at 14:48 comment added James S. Cook If you are doing this for calculus then you should probably take some time to learn the common cheat sites. Wolfram alpha and others show steps, however, the steps are often inauthentic when compared to real human calculation. You'll know it when you see it. Running your problems though "symbolab" before you grade may be eye-opening. We found something like half of the students use a website for the online calculus test... even after being told to do no such thing. In the absence of proctoring it is a real problem.
