how does that work? they forget everything they learned in the past year if they don't go to school for two months? i can understand setbacks, increase of behavioral issues, but completely cancelling out?
Over 3 months it's easy to forget something that you probably only had a tenuous grasp on. My father was a high school teacher and loathed Christmas break. "I spend 4 months pouring information in, and it's gone in 4 days."
In addition, higher socioeconomic status children keep making progress during the summer.
