> There is a field of education, that studies teaching and learning! In fact many of you who attended university and studied at a "school of computer science" would have been in a building next to a "school of education".

Yes, people know. Education schools aren’t held in low esteem by social scientists or the educated public by reason of lack of familiarity. They can’t even manage a detectable effect on teacher effectiveness. Note I did not say large. The effect of an education degree on teacher effectiveness is not reliably distinguishable from zero.

> It's easier to pick a good teacher than to train one: Familiar and new results on the correlates of teacher effectiveness

> Neither holding a college major in education nor acquiring a master's degree is correlated with elementary and middle school teaching effectiveness, regardless of the university at which the degree was earned. Teachers generally do become more effective with a few years of teaching experience, but we also find evidence that teachers may become less effective with experience, particularly later in their careers. These and other findings with respect to the correlates of teacher effectiveness are obtained from estimations using value-added models that control for student characteristics as well as school and (where appropriate teacher) fixed effects in order to measure teacher effectiveness in reading and math for Florida students in fourth through eighth grades for eight school years, 2001–2002 through 2008–2009.
