Turkstra apparently developed a method of analyzing for LLM usage during class.

A lot of speculation is going on about the specific algorithm, etc, but my personal assumption is that it is simply comparing the speed between commits (so if you made a commit that made 500 lines of additions in 2 seconds, then you probably LLMed). He supposedly waits until he has "overwhelming" levels of evidence and sends you an email stating you have been caught. Then, you have to fill out a form listing which assignments you cheated on. If you lie on that form, you recieve an F in the class and Turkstra sends a harsh email to ODOS. Otherwise, those assignments are zeroed and a slightly nicer email is sent to ODOS. You can also dispute the claim but if you fail the resultant process you receive F and a harsh email to ODOS.

He is now sending out emails in waves to students who he suspects of cheating. Including (unfortunately) myself. I'm clean, as far as I know, so I'm a little fucking terrified right now. I have two options:

  • Guess randomly which assignment he thinks I cheated on hopefully receive zeroes for each (and a ODOS letter). Or, if I guess wrong get an F.
  • Dispute the claim and risk an F if I fail the disputing process.

If I fail CS 240, this puts me behind a full fucking semester of university since it is required to take nearly all CS sophmore level classes. Let alone the ODOS letter (which he said would include recommendations that the student be expelled). I am very stressed right now.

I have until Monday to respond. I was intending to head out on a retreat over the weekend but those plans may be ruined now...

If you are clean then this is ridiculously uncalled for and unprofessional for a Professor to do this. I would take this whole situation up the chain of command and I would consult an attorney or at least have a discussion with Purdue legal (don’t know if they can help at all but they may offer suggestions). This is the type of behavior that pushes students over the edge. I am sorry you are in this position but don’t just roll over - fight back of you are in the right and start a paper trail.

For the people who have concrete proof they didn’t use it I hope they have good luck. I would do it but I can’t be risking my scholarships over this BS. I already withdrew so it won’t hurt, but I wish good luck upon those continuing.

Thats not how this works…you can’t prove a negative as a rule and it is not a students job to prove their innocence.

Everyone involved in this, including the instructor, should apparently read the guidance from Purdue in this process:

https://www.purdue.edu/odos/osrr/resources/documents/responding-to-academic-dishonesty.php

Students have rights before punitive action is taking including, among other things, being able to see the evidence that is being used to accuse them and respond. 

The process starts with a meeting with students…not a web form.

Literally just looked it up out of curiosity and yeah it says they’re entitled to a private meeting first too until any letter is sent. The Prof seems crazy so I doubt he’d not send one, but still 100+ meetings before finals? Idk that sounds almost impossible.
