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.

Just to deliver one high-quality 45 minute lesson requires many hours of planning in advance.

In North Carolina, for example, it takes 15 years to move a teacher's salary from $30,000 to $40,000. So it's really difficult to argue that pay doesn't have something to do with the lack of prestige.

This is something that Randi Weingarten said to me when I interviewed her once, which I think I quote in chapter nine. She talks about how only 7 percent of private sector workers in the American economy are in unions. So all the protections that teachers have that are due to collective bargaining - including generous pensions, generous health plans, limits to what they can be asked to do after school and in the summers - all of those things are sources of resentment to the public. And I think that politicians have played off of that quite effectively.

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.

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.

If you're afraid to talk to the other adults in your school it is definitely throughout history the hallmark of a failing school. When I was writing about the teachers' strike in New York City in 1968, the middle school where events triggered that strike was a place where teachers were known to hide in their classrooms.
