I think the point the author makes is fundamentally correct: the correctness of answers comes from human reasoning, and is subject to discussion and debate. It's not something completely external, and education shouldn't be a game to guess what these external decrees are. As the author says, what should matter is what the student thinks is correct, not whether they think their answer will be accepted as correct. However, the author uses language that is belittling and rude. I think that teachers who use students as an emotional outlet for their frustrations are very harmful. I would rather see the teacher find another way to get the students to see her point of view, than emotionally browbeating them.
