In a continuing fall-out from Motoko Rich’s article in the New York Times about charter teachers who plan on a two-or three-year career, Sara Mosle reflects how her own views about teaching have evolved. When she joined Teach for America some 20-plus years ago, she was part of a cohort that thought that youthful enthusiasm was superior to experience. It was not uncommon for her and her colleagues to put in 100-hour weeks.

Now that she is older and a parent, she sees things differently. For one thing, she sees the need for veteran teachers. For another, she sees that 100-hour work weeks are impossible for those who have a family or a life outside of work. And she believes that being a parent has made her more understanding of the hopes, fears, and responsibilities of parents.

My reflection on her article: She is not saying that you have to be a parent to be a good teacher; she acknowledges, as Wendy Kopp does not, that inexperience is not a virtue but a starting point on the learning curve of a challenging profession; she implicitly (and maybe explicitly) challenges the charter model that assumes a workforce of teachers who are 22 or 23, only a few years older than their students, ready to work 100 hours a week and then move on to find their real career elsewhere.
