> One time I heard someone praised as a good teacher. Not knowledgeable, but a good teacher. I objected that if someone is ignorant but a good teacher, does that mean they’re effective in conveying their ignorance? Wouldn’t that be a bad thing? No, all that mattered was that he was a good teacher. I need more context. An elementary school teacher that is really great with students but doesn't know much beyond the books and other materials is probably a good part of the 6 or more teachers a student will have. It doesn't say professor but even then it seems like an odd demand to me.
