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.

I don't think school reform should be motivated by missionary zeal. I think it should be motivated by evidence of what works.

I always make the point that teachers are people too, and that they don't just want to be in front of kids all day and have children be their only feedback loop.

I wrote a work of history, I looked at over 500 sources - I spent three-and-a-half years on the project. I think the most gratifying and wonderful thing about the reaction is that people are learning things from the history that feel relevant to today.

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.

Definitely we see throughout history that American teachers are asked to be very self-abnegating. They're not supposed to be concerned with the conditions of their labor, they're not supposed to care about pay. This is the kind of vision of the ideal teacher, which is again and again brought to the fore by reformers, the ideal teacher as someone who is passionately driven to serve children. Almost to the exclusion of a more pragmatic view of what the job actually entails.

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.
