I've been teaching high school for a decade, and I'm genuinely torn on whether homework still matters. Last year, I stopped assigning it for one unit and test scores actually went up slightly, but that could've been because the material was easier. Research like John Hattie's meta-analyses shows homework has a small effect in secondary school, yet nearly zero in primary grades. So, is mandatory homework just a relic of an era before teachers could share resources online, or does it still build the discipline and study habits that students need for college?
