The education establishment is in a twit over the phenomenon called "summer slide." "Summer slide" is the loss of knowledge/competence in the summer months, according to research done by the RAND Corporation and Johns Hopkins University. "Summer slide" disproportionately plagues poor kids of color, so the recent, alarmingly low scores recorded by urban students on the Common Core tests heightened sensitivity around this issue.
Rather than acknowledging the corrosive effects of poverty, or conceding that the testing and accountability era has been a failure and has driven lousy practices, the answer is to make the least privileged kids work longer and harder while their more affluent peers summer in the Hamptons or South of France.
