It takes us back to the starting point of trying to define the outcome we want, but just because the MET study did not
validate observation scores should not mean that teaching and test scores now are equivalent.»
After extensive research on teacher evaluation procedures, the Measures of Effective Teaching Project mentions three different measures to provide teachers with feedback for growth: (1) classroom
observations by peer - colleagues using
validated scales such as the Framework for Teaching or the Classroom Assessment
Scoring System, further described in Gathering Feedback for Teaching (PDF) and Learning About Teaching (PDF), (2) student evaluations using the Tripod survey developed by Ron Ferguson from Harvard, which measures students» perceptions of teachers» ability to care, control, clarify, challenge, captivate, confer, and consolidate, and (3) growth in student learning based on standardized test
scores over multiple years.
So the folks at Gates have been trying to scientifically
validate a teacher evaluation system that involves a mix of test
score gains, classroom
observations, and student surveys so that they can overcome resistance to centrally imposed, mechanistic evaluation systems.
