After sitting through a webinar by an accomplished professor regarding Common Core Standards, I wished he had done the following research: gather a few hundred successful adults in a room from a variety of careers: law, construction, music... (and define "successful" almost any way you want -- salary, prestige, influence...)
Then give them a test that reflects the Common Core Standards. If any appreciable number of successful people answer a question incorrectly, then there's nothing standard about that parcel of knowledge; it would be removed from the standards -- and instead gently placed in a pile called "guidelines."
Seriously, would someone please ask Barak Obama to "know and apply the Binomial Theorem for the expansion of x + y)n". Has anyone ever done research like this?
