9. "Virtually all of the advantage that wealthy students have over poor students is the result of differences in the way privileged kids learn when they are not in school…. America doesn’t have a school problem. It has a summer vacation problem …" –Malcolm Gladwell, Outliers, pp. 258 - 260

10. How Quickly Things Can Change Summer Loss: The Phenomenon No One Wants to Deal With: “Schools whose poor children are learning over the year will suffer because summer loss will cause them to fall farther and farther behind their middle-class peers and to fail to show much growth in reading and math. It will thus appear that the schools are failing, and they will be blamed for what is happening – or, more accurately, is not happening – in the family and the community.” Gerald W. Bracey Phi Delta Kappan, Sept. 2002 “Summer learning loss …is devastating. There is a ton of research. We need to do something about it. [Children] get to a certain point academically in June, and over the summer they lose that. They come back in September further behind. It is literally a step backwards. I worry a lot about children from disadvantaged backgrounds falling behind at the time we need to be accelerating their rate of improvement.” Arne Duncan, Secretary of Education, Interview, June 25, 2009
