How Would You Handle Students Cheating?
I gave my students a take home exam over spring break. (This is normal where I teach) One of the questions was particulary difficult. It came down to a factor of three in the solution. That factor inexplicably appeared with no justification on many of their exams. I intend to have the students I suspect of cheating come to my office to solve the problem on the board. What would you do?
Edit: I gave them the Tuesday before spring break until the Thursday after. I didn't want it to be right before or right after.
When I say normal I mean giving take home exams.

There has to be evidence of their process for me to accept it as evidence of understanding/ability. I have made it clear to them that this is necessary. Their job is to convince me that they know what they're doing. (But... I'm teaching HS Mathematics). So .. I'd mark it wrong/incomplete. I'm also working on student understanding of consequences of their actions, so wouldn't give them another opportunity on that exam. They would need to improve things on the next exam.
How do you deal with students who say "my gut says it works this way. This is an easy problem, the answer is obvious. I don't know how to explain it to you any more simply"?
I mean, it takes 162 pages to formally prove that 1+1=2, but we got by just fine before we wrote down that proof. We just knew the answer, we couldn't explain how. If a student is gifted, a high school level problem could be as simple to them as 1+1 is to most people. They might know and not be able to explain how. Now, in a university environment I'd expect them to learn the proof, but that's not the point of high school maths, is it? The point of high school maths is to know how to solve the problem, not to know why the solution works.
I found the equivalent of high school maths in my country to be similarly intuitive and trivial. The kids who think that the maths they're being taught is obvious will just memorise what the examiners want to see and regurgitate it even if they feel like it's teaching shapes to a baby. If you are "gifted" and truly do understand it then it shouldn't be hard to just overexplain (which is what most exam boards are looking for)
Yeah, I figured that out in high school too. I think it just irks me that different students are being graded on a different standard, subjectively speaking. The neurotypicals are being judged on their ability to learn, while the gifted kids are being judged on their ability to explain. Maybe the gifted kids wanna learn too. They're all told their whole lives the point of school is to learn, and then they're met with disappointing reality. We expect gifted kids to grow up so fast, and having to explain the material back to the teacher to prove they know it doesn't help. I wish they got to spend a little longer just being kids.
This is ridiculously backwards, Whitehead and Russell's motivation for writing the PM was to come up with a set of axioms and deductive rules that the entirety of mathematics could be derived from. When they worked out their proof that 1 + 1 = 2, it didn't tell the world that now 1 + 1 = 2 is now officially a fact, it told the world that the logic and axioms they built were enough to be capable of deducing some very simple facts that we've already been confident are true. The hope was that maybe if we keep working at this and modifying our rules when need be, we'll be able to get a set of axioms and inference rules that are sufficient to determine the truth of any mathematical question. Calling that a proof that 1 + 1 = 2 would be saying their brand new theory was somehow more valid and more fundamental than addition of natural numbers.
A few years later Gödel came along and completely obliterated any hope of a project like that succeeding, and today literally no one thinks of the PM as more than a historical curiosity. (If you actually wanted to prove 1 + 1 = 2 from first principles today, you'd use the Peano axioms for the naturals: S0 + S0 = S(S0 + 0) = SS0, done.)
That's a tangent from the actual topic but I feel compelled to call it out.
Getting back on track, probably 90% of the points I give on exams are for partial credit, because there need to be distinctions between having no clue, knowing where to start and getting stuck, understanding essentially every meaningful step but then writing 1 + 1 = 3 to wrap up, etc. I'm grading on both their ability to solve problems and their ability to communicate their ideas. Both are equally important.
This is very controversial, but I don't go out of my way at all to worry about cheating. I don't want to play policeman and teach with the mindset that my students are potential criminals. Even if I'm 99% sure a student is cheating, if I'm in the profession long enough I'll eventually hit that 1% where I'm giving a decent student an undeservedly hard time. I'm not paid anywhere near enough for it to be worth having a more adversarial relationship with my students.
I had a student earlier this month where it looked like he probably snuck out his phone for an exam. I just wrote a note on those problems that I couldn't follow his work and wasn't comfortable giving points for work I don't understand, please walk me through your solutions for the points back. I told him this verbally as well when I handed it back to him as well. He never took me up on that, but it feels more humanizing than just calling him a cheater. I think OP is getting at something similar, but I think there's value in not phrasing it in an accusatory way.
Being somewhat sympathetic to OP though, there is a sense of feeling insulted when a student puts very little effort into pretending they're not cheating. I try not to take it as an affront to me personally and imagine that they do the same for all their instructors, but I do feel kind of peeved sometimes.
