“It is true that we have an unfair society, and it is true that kids who are coming from the poorer backgrounds and whose parents don’t do a lot of reading are losing reading skills over the summer,” said Peter Gray, research professor of psychology at Boston College. “But let’s look at other solutions.” He added, “Whatever job we give to the school system, they ruin it.”(emphasis added)
I will resist the temptation to toss some psychology into why we'd have a professor of psychology making such a generalization, but...really, Professor Gray? Every single thing? Ever?
And regarding summer learning loss, be sure to read Alfie Kohn on just what it is we're losing.
