I have had to interview numerous High School graduates and Junior College attendees who were so bad at math they couldn't run a cash register. What evidence is there to indicate that "schooling" over the summer is a benefit to them or Society at large?
Although I object to his lack of citations, real proof, and his use of innuendo and other false arguments, I strongly agree that John Taylor Gatto http://johntaylorgatto.com/ is right: The American Education system is irrevocably broken and must be redesigned from scratch. The school system is (WARNING!:GROSS GENERALIZATION AHEAD!) something where you send your kids to prison during the working hours to have their heads messed with by persons only marginally capable of feeding themselves .
OK, I agree that there are SOME dedicated and competent teachers, but I suspect they are working in an environment that systematically sabotages their best efforts. It is also true that some students do well in spite of the average school environment. These anomalous students maybe have access to better schools, better teachers, and better parents.
The idea of making students go to school year-around is case of "jumping-to-solutions" and avoids any real thinking about "How can we improve our educational system?"
