Raddy, saying the curriculum can be "delivered" assumes that the kids are like buckets to be filled; they hear it once, it's been delivered to them, they understand and can use it. But they aren't buckets.
Some (rare) kids are like that for some subjects, but the vast majority are not; most need to have a lot of rote practice, see variations on the concepts, and extend and apply the concepts themselves before they "get" it and it's theirs to keep. Retention rate on lecturing alone: ca. 10%. Retention rate on active learning tasks: closer to 75%.
OTOH, two plus hours of homework load isn't reasonable; it leaves pretty much no time for other learning I think is just as important. Learn to wash a car, iron a shirt, use a bank card, play a musical instrument, the rest of life that isn't academic but is important.
