In my CS undergrad I had Doug Lea as a professor, really fantastic professor (best teacher I have ever had, bar none). He had a really novel way to handle homework hand ins, you had to demo the project. So you got him to sit down with you, you ran the code, he would ask you to put some inputs in (that were highly likely to be edge cases to break it). Once that was sufficient, he would ask you how you did different th…
Yep, it's easy to shortcut AI plagiarism, but you need time. In most of the universities around the world (online universities especially), the number of students is way too big, while professors get more and more pressure on publishing and bureaucracy.

#122This is the correct take. To contrast the Terance Tao piece from earlier ( https://news.ycombinator.com/item?id=46017972 ), AI research tools are increasingly useful if you're a competent researcher that can judge the output and detect BS. You can't, however, become a Terence Tao by asking AI to solve your homework. So, in learning environments we might not have an option but to open the floodgates to AI use, but aba…
Yesterday's Doonesbury was on point here: https://www.gocomics.com/doonesbury/2025/11/23 Andrej and Garry Trudeau are in agreement that "blue book exams" (I.e. the teacher gives you a blank exam booklet, traditionally blue) to fill out in person for the test, after confiscating devices, is the only way to assess students anymore. My 7 year old hasn't figured out how to use any LLMs yet, but I'm sure the day will come…
All for a calculator that can lie.
Re: Implications of AI to schools
#123So it is feasible (in principle) to give every student a different exam!
You’d use AI to generate lots of unique exams for your material, then ensure they’re all exactly the same difficulty (or extremely extremely close) by asking an LLM to reject any that are relatively too hard or too easy. Once you have generated enough individual exams, assign them to your students in your no-AI setting.

Most learning curves in the education system today are very bumpy and don't adapt well to the specific student. Students get stuck on big bumps or get bored and demotivated at plateaus. AI has potential to smooth out all curves so that students can learn faster and maximize time in flow. I've spent literally thousands of hours thinking about this (and working on it). The future of education will be as different from…
There is a huge opportunity here to have the stick smacking be automated and timed to perfection.
People thought the threat of physical violence was a good way to teach. We have learned better. What else is there for us to learn? What have we already learned but just don't have the resources to apply?
I've met many educators who have told me stories of ambitions learning goals for students that didn't work because there weren't the time or resources to facilitate them properly.
Often instructors are stuck trading off between inauthentic assessments that have scalable evaluation methods or authentic exercises that aren't feasible to evaluate at scale and so evaluation is sparse, incomplete or students only receive credit for completion.
Re: Implications of AI to schools
#125One of my students recently came to me with an interesting dilemma. His sister had written (without AI tools) an essay for another class, and her teacher told her that an "AI detection tool" had classified it as having been written by AI with "100% confidence". He was going to give her a zero on the assignment. Putting aside the ludicrous confidence score, the student's question was: how could his sister convince the…
When I was in college, there was a cheating scandal for the final exam where somehow people got their hands on the hardest question of the exam. The professor noticed it (presumably via seeing poor "show your work") and gave zero points on the question to everyone. And once you went to complain about your grade, she would ask you to explain the answer there in her office and work through the problem live. I thought i…

80% is catastrophic though. In a classroom of 30 all honest pupils, 6 will get a 0 mark because the software says its AI?
I suppose 80% means you don't give them a 0 mark because the software says it's AI, you only do so if you have other evidence reinforcing the possibility.
Re: Implications of AI to schools
#127It ended up being harder then writing an ordinary paper but taught us all a ton about citation and originality. It was a really cool exercise.
I imagine something similar could be done to teach students to use AI as a research tool rather then as a plagiarization machine.

I think it means every time AI is used, it will detect it 80% of the time. Not that 20% of the class will marked as using AI.

Doesn't google docs have fairly robust edit history? If I was a student these days I'd either record my screen of me doing my homework, or at least work in google docs and share the edit history.
Yes. When I was an educator, reviewing version history was an obvious way to clarify if/how much students plagiarized.

> Detecting artificial typing patterns is a little more tricky, but also feasible. Keystroke dynamics can detect artificial typing patterns (copying another source by typing it out manually). If a student has to go way out of their way to make their behavior appear authentic then it's decreasing advantage of cheating and less students will do it. If the student is integrating answers from multiple AI responses then m…
It will take 0 time to have some (smarter?) student create an AI agent that mimick keystrokes.
The best solutions are in student motivations and optimal pedagogical design. Students who want to learn, and learning systems that are optimized for rate of learning.
