 The correct answer here seems clearly enough to be “it depends”. For very young children who have yet to acquire or develop the ability to subject teacher declarations to critical scrutiny, there seems to be little alternative to accepting what their teachers tell them. For older and more cognitively sophisticated students there seem to be more options: they can assess them for plausibility, compare them with other opinions, assess the teachers’ proffered reasons, subject them to independent evaluation, etc. Regarding “the teacher says that p” as itself a good reason to believe it appears moreover to contravene the widely shared conviction that an important educational aim is helping students to become able to evaluate candidate beliefs for themselves and believe accordingly. That said, all sides agree that sometimes believers, including students, have good reasons simply to trust what others tell them. There is thus more work to do here by both social epistemologists and philosophers of education (for further discussion see Goldberg 2013; Siegel 2005, 2018).
