In my in person classes I used contract grading and weighed in class participation and case studies at 75% of their contract. The final was optional and was from a list of possible choices. I'd focus on providing mentorship and feedback, not grading them, simulating real world growth and learning. I had no AI problems and both I and my students generally loved it.
I taught one online class. It sucked. I hated it. Rampant AI and totally fabricated everything. Even reflection paragraph posts. I need to learn how to design an online class like my in person ones. Until then, never again.
Most of the AI users were student athletes. I can quantify this, so I'm not exagerating. They would miss classes for travel, turn in AI slop, and I would have to fail them over and over. That online class was 60% student athletes. I tried so hard to talk sense and be accommodating, but it was unabashed AI everything. It was bad.
The student athletes are getting more screwed than normal because they are just faking it through college and getting exploited by the NCAA for money.
