Study of Teacher Effectiveness: Two Sets Of Eyes Better Than One
There’s plenty to consider in the final report of the Bill & Melinda Gates Foundation’s* three-year Measures of Effective Teaching (MET) study, which was released Tuesday.
Here’s one of the interesting highlights: Researchers found it was better to have two different evaluators observe a classroom, rather than have one evaluator make multiple visits to watch the same teacher. Additionally, the study concludes that using multiple measures — test-score growth data, feedback from students, and the observations of teachers at work — also helped craft a fairer portrayal of a teacher’s effectiveness.
The MET project has been a source of contention and controversy from its inception. As Education Week’s Stephen Sawchuk notes:
Taken as a whole, the final MET findings provide much food for thought about how teacher evaluations might best be structured. But they are not likely to end a contentious, noisy debate about evaluation systems, and they are almost certain to be intensely debated, in part because of Gates’ separate support for advocacy organizations that have already staked out positions on teacher evaluations.
