It is common that school math textbooks are supplemented with instructor's materials (answers, hints and guidelines). Are there scientific studies on how instructor's materials impact math teaching? Any reference about the world of instructor's material (design, principles, uses, etc.) are welcome.
$\begingroup$ I don't know of any (but I don't know much of math education literature), although I would be surprised if this were not something that has been academically studied several times. That said, it's worth mentioning that the stimulus for such materials is almost entirely a financial decision for the publisher and is not really motivated by its impact on math teaching, although the individual writers of such material, often being teachers or former teachers, probably keep its impact in mind for personal altruistic reasons. $\endgroup$– Dave L RenfroDec 22, 2022 at 18:59
$\begingroup$ It'd be my impression that nowadays it's mostly publishers who insist on such things... and students who want to covertly acquire them. Serious instructors know not to entirely trust such material, in the first place, but/and also don't really need to look at it, anyway. So I'd anticipate that an answer to the question, as posed, would be misleading, due to built-in assumptions. But ... I don't know... $\endgroup$– paul garrettDec 22, 2022 at 19:53
