I feel that people have asked me my age I don't actually think that thirty is particularly young for a first book to come out. And I sometimes wonder if a male author would have been asked this question so frequently.

Coming to the civil rights movement in the twentieth century, we begin to have this idea that's still with us today, which is that the main purpose of public education is closing achievement gaps.

What happens from about 1954 to the late 1980s, is that we see a huge wave of optimism that school desegregation is going to be the way to improve educational outcomes for poor children of color. And we see a consensus build on the left and in the center that this is going to be a transformative education movement like none other we've seen in American history.

Younger teachers are definitely more likely to have worked at charter schools as opposed to have just heard of them. Charter schools explicitly look, often, to hire younger people. I've even talked to people who didn't necessarily go into teaching thinking they wanted to work at a charter school or even may have been considered critics of the charter school movement, and found that it was the only way for them to get their foot in the door. So young people just have much more familiarity with the concept.

If you look at the early nineteenth century you see the idea that we educate children to be voters and to be participants in our popular democracy. And then at the turn of the century when more and more immigrants are coming into the schools, Americanization becomes a more explicit part of the agenda.

I believe everyone in the education sector should be looking at evidence, reassessing, making tweaks to figure out what works, I think it's a positive model.

The first generation of school reformers I talk about - nineteenth century education reformer Horace Mann, Catharine Beecher - they are true believers in their vision for public education. They have a missionary zeal. And this to me connects them a lot to folks today, whether it's education activist Campbell Brown or former D.C. public schools chancellor Michelle Rhee. It's a righteous sense, a reform push that's driven by a strong belief in a particular set of solutions.
