Teaching isn't blatting someone's mind with the Correct Answers and checking whether the overwrite took. Instead, you empirically build a model of the student's own world model, then examine the model to see where it fails to conform to reality, and construct ways to fix it. The example from TFA was consistent with "this is university coursework", which is fertile ground for a tutor to identify such errors! It's not like the student should be receiving a yes/no response and nothing else; there will presumably be comments on the incorrect answers.
