What measures the best teacher? More than scores, study shows

Stephanie Simon:

Effective teachers can be identified by observing them at work, measuring their students’ progress on standardized tests – and asking those students directly what goes on in the classroom, according to a comprehensive study released Tuesday.
The three-year, $50 million Measures of Effective Teaching study, funded by the Bill & Melinda Gates Foundation, found it was difficult to predict how much students would achieve in a school year based on their teacher’s years of experience or knowledge of pedagogical technique.
But researchers found they could pick out the best teachers in a school and even predict roughly how much their students would learn if they rated the educators through a formula that put equal weight on student input, test scores and detailed classroom observations by principals and peers.
