Duolingo

Yea, responding to student's questions is a critically important aspect of teaching, and especially when dealing with children who are in the process of learning how to use words correctly, I can't see AI doing anything remotely close to a good job.

Any level. Early level and the kids may not even know what questions to ask and they certainly can't fact check the AI. Late level and you need your own knowledge base to think critically and develop new things and use old things in new ways.

I second this question.

I mean hell, AI would just as soon mark a simple math solution wrong because it somehow thinks 1 + 3 and 3 + 1 aren't the same when obviously they are.
