What makes a great teacher?

What makes a great teacher? Probably not what you think. Here is an article in the Atlantic describing data collected and analyzed by Teach for America (the non-profit organization that recruits recent college graduates and professionals to teach for two years in low-income communities throughout the US).

Starting in 2002, Teach for America began using student test-score progress data to put teachers into one of three categories: those who move their students one and a half or more years ahead in one year; those who achieve one to one and a half years of growth; and those who yield less than one year of gains.

According to the article, the characteristics could be summarized as:

set big goals

continuously seek to improve effectiveness

recruit students and families into the process

plan exhaustively and purposefully

work backwards from desired outcome

refuse to surrender to [...] bureaucracy and budgetary shortfalls

At the moment, TfA claims larger gains than can be independently verified (which are also only for math) but their approach still looks promising...

So far, only one independent, random-assignment study of Teach for America’s effectiveness has been conducted. That report, published by Mathematica Policy Research in 2004, looked at the organization’s teachers and found that, in math, their students significantly outperformed those of their more experienced counterparts. (In reading, though, the teachers’ students did the same as other teachers’ students.) Another study is due out in 2012 or 2013.
