THE ALLURE OF TEACHER QUALITY
A focus on "teacher quality" has been a dominant reform paradigm over the past few years, and its allure as the key ingredient to student success is powerful but reductive, writes Matthew Di Carlo on the Shanker Blog. Its appeal has been fueled by the availability of datasets that link teachers to students, as research on test-based effectiveness has grown in size and sophistication. And it is true, Di Carlo says: Analysis after analysis finds that all else equal, the effect of "top" versus "bottom" teachers is large. Even when some variation is attributable to confounding factors, discrepancies are still larger than with any other measured input. But the essential question, Di Carlo writes, is whether and how we can measure teacher performance at the individual level and thereby (more importantly) enhance teacher performance.
