Premises, presentation and predetermination In the Gates MET study
Blog by Matthew Di Carlo/Shanker Blog
The National Education Policy Center today released a scathing review of last month’s preliminary report from the Gates Foundation-funded Measures of Effective Teaching (MET) project. The critique was written by Jesse Rothstein, a highly-respected Berkeley economist and author of an elegant and oft-cited paper demonstrating how non-random classroom assignment biases value-added estimates (also see the follow-up analysis). Very quickly on the project: Over two school years (this year and last), MET researchers, working in six large districts—Charlotte-Mecklenburg, Dallas, Denver, Hillsborough County (FL), Memphis, and New York City—have been gathering an unprecedented collection of data on teachers and students, grades 4-8. Using a variety of assessments, videotapes of classroom instruction, and surveys (student surveys are featured in the preliminary report), the project is attempting to address some of the heretofore under-addressed issues in the measurement of teacher quality (especially non-random classroom assignment and how different classroom practices lead to different outcomes, neither of which are part of this preliminary report). The end goal is to use the information to guide in the creation of more effective teacher evaluation systems that incorporate high-quality multiple measures. (more…)
