@theloniusmonk There was a study a few years back which showed that USA students had more homework than kids in most industrialized countries, yet they were fairly low in performance. Basically, USA students weren’t under-performing compared to other countries because they were lazy, but because they were wasting time in mindless repetitions of the same stuff instead of learning and mastering concepts.
So yes, not only is homework overrated, it’s counterproductive, at least the way it is used in the USA.
