You can read the answer to that question from my favorite writer on education reform issues, Richard Rothstein.

He last paragraph reads:

“If we want to narrow the achievement gap as well as raise student achievement, we have to… combine school improvement with narrowing the socioeconomic inequalities that influence children’s development outside of school.”

His response to that question is one of fifteen that were invited by the National Journal blog.

None of the invitees were K-12 teachers.
