Are Common Core standards a step in the right direction?
I believe they are. If everyone in the country could be taught by the top 25 percent of teachers, that would close the gap by itself. But that's not possible. I found that systems that were [implementing] best practices and prescribing the superman habits – you know, this is the way to speak, and this is the way to teach – were [able to make] a system of collective supermen.
