Author, Robert Kaplinske compares math instruction to eating a balanced diet. Mistakes teachers make in solving robust problems: breaking down the problem to individual skills so that students have consumed all required skills. The math problem then no longer resemles the original form; instead, they become a collection of disconnected skills as in a textbook factory. The Common Core Standards the potential to take a more balanced approach, not the current long list of skills taught in isolation with no context. This he says is like taking lots of dietary supplemenhts instead of maintaining a healthy diet of whole foods rather than adding a bunch of vitiamin/mineral pills.
Strange comparison, but Kaplinske has it correct. It makes sense to teach one skill thoroughly. How do you feel?
