The best advice that no one is taking

I read this NYT article by Elizabeth Green telling the story of two math educators and their roles in improving teaching.  Akihiko Takahashi and Magdalene Lampert have had unique experiences in studying American math lessons, and I was unfamiliar with both before discovering Dan Meyer’s blog reference to the article.

The parallels between modern Common Core math curriculum efforts and past top-down initiatives is striking.  We have no shortage of creative ideas or eagerness to try new things in our classrooms.  What’s missing most is quality teacher training and professional development, the author claims.

How would schools need to be restructured/supported to create this kind of change?
