Is School Choice Enough?

A interesting discussion on City Journal on the subject of school choice. The discussion in a response to an article by Sol Stern implying that school choice advocates need to look at plan B. The discussion is fascinating given that all the authors (including Stern) agree that school choice is beneficial, and most agree that with the statement that school choice is not "panacea." The discussion really focuses on four aspects:

1. Does/can school choice result in competition that improves public education across the board?
2. Is school choice politically viable? Is significant expansion of school choice realistic?
3. Can school choice overcome problems inherent in education (e.g. teacher education/schools of education, flawed curriculum and pedagogy, low and misguided standards)?
4. Is curriculum reform a better, more viable option? Should school reformers make curriculum reform the priority?
