In discussing how to adapt teaching methods, we have also looked at evaluation by LLM. The most talked about concern now is the unreliability of LLM output. However, say that in the future, accuracy of LLMs improves to the point that it is no longer a problem. Would it then be good to have evaluation by LLM? I would say generally not, for two reasons. First, the teacher needs to know how the student is developing. To get a thorough understanding takes working through the student's output, not just checking a summary score. Second, the teacher needs to provide selective feedback, to focus student attention on the most important areas needing development. This requires knowledge of the goals of the teacher and the developmental history of the student. I won't argue that LLM evaluation could never be applied usefully. If the task to be evaluated is simple and the skills to be learned are straightforward, I imagine that it could benefit the students of some grossly overloaded teacher.
