Agreed. Per several of the grade school teachers at my sons school, almost the whole first half of a school year is dedicated to reteaching what was learned the second half of the previous year due to losing that knowledge during the summer break. "If you don't use it, you'll lose it" truly applies.
I'd like to see something to the effect of several weeks on, one or two weeks off throughout the entire 12 months - something that'll equals to around the same amount of school days kids have today. If that were to happen, maybe we wouldn't need to increase the daily school hours.
