But why won't the crop grow on its own? It is strongly incentivized to live! And yet it does not. So you need to send photos of tilling the soil, planting the seed, watering, so that one day we might come there and see a harvested crop.
My (UK) University was very clear that attendance was not mandatory, but if you weren't attending lectures you were not going to get any extra help from the lecturers etc
I don't think that's an unreasonable position to take, but it's nice if you _know_ rather than _guess_ who bothered to make it in to class.
If you fail someone who rarely attended class, and they claim that they did, asked you for support, and never received it, how might you defend yourself?
If you have an excellent student who encounters a hardship, how might you petition for leniency to allow them to drop without penalty beyond a cutoff, or delay submitting final grades until they can complete makeup work?
If you believe lack of attendance is "wasting resources", then either you think the class isn't doing its part by teaching what students need, or you believe it is and yet students are not learning the material due to lack of attendance. In the former case, the problem is poor teaching, and so attendance isn't the solution. In the latter case, then the same argument would apply regardless of who's paying.
What's the logic here? Is there a third possibility I'm missing?
Now imagine you're a big donor. You donate enough money for, say, 10 scholarships. None of them attend class. None of them get degrees. Are you likely to donate again?
