As a progressive educator of thirteen years, I agree with Hacker and Dreifus in “Who’s Minding the Schools” ( http://www.nytimes.com/2013/06/09/opinion/sunday/the-common-core-whos-minding-the-schools.html?pagewanted=all&_r=0 ) when they conclude that teachers should be “allowed to work professionally without being bound by reams of rules.” That said, it’s not like the Common Core creates standards where none existed before; for my entire teaching career in California, I’ve been beholden to standards—state rather than national, but standards nonetheless. And, for the most part, I greatly prefer the Common Core standards to the California State Standards. The former are much more holistic and critical-thinking based than the latter. While the state standards were almost a checklist of facts the students should know, the Common Core standards approach learning more as habits of mind, ways to think and learn. This is a progressive approach to education. Yes, these standards are more challenging, but this is a challenge I welcome.
