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 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.

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.

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.

When you see that 76 percent of teachers are female, I think you have to acknowledge that there's a cultural bias, and it does date back to this nineteenth century idea that teaching is a form of mothering.

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.

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.
