There are a lot of polls that show that actually Americans have a pretty high opinion of teachers, that Americans think teachers are just about as prestigious as doctors. And yet there's this political conversation - this reform conversation - that paints a very negative picture of the effectiveness of the teaching population. So there's definitely a tension between the way teaching is talked about and understood at the political level and how everyday average Americans think about teachers.

There's a small movement of teacher-led schools across the country. These are schools that don't have a traditional principal, teachers come together and actually run the school themselves. That's kind of the most radical way, but I think something that's more doable across the board is just creating career ladders for teachers that allow certain teachers after a certain number of years to inhabit new roles. Roles mentoring their peers, helping train novice teachers to be better at their jobs, roles writing the curriculum, leading on lesson planning.

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.

[Nineteenth century American educator] Catharine Beecher is really associated with the idea that a mother works with children in the home and a teacher works with children at school, and that therefore women are almost biologically predisposed to do this job.

I don't think school reform should be motivated by missionary zeal. I think it should be motivated by evidence of what works. I have been critical of Teach For America in the past but I think one of the things about their model that's interesting is that they're constantly looking at it and whether what they're doing works and reassessing their model, and making changes. So to the extent that 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.

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.

The question is rarely asked, "Why is it that so few other Americans have these protections?" The question is more often asked, "Why do teachers have it so easy?"
