Does Professor Quality Matter? Evidence from Random Assignment of Students to Professors
Carrell and West (JPE 2010)
Abstract is:
In primary and secondary education, measures of teacher quality are often based on contemporaneous student performance on standardized achievement tests. In the postsecondary environment, scores on student evaluations of professors are typically used to measure teaching quality. We possess unique data that allow us to measure relative student performance in mandatory follow‐on classes. We compare metrics that capture these three different notions of instructional quality and present evidence that professors who excel at promoting contemporaneous student achievement teach in ways that improve their student evaluations but harm the follow‐on achievement of their students in more advanced classes.
諸行無常....っていうのはちょっと違うか。
このタイプの研究だと，教育の質は学生の出来に影響しない（逆に言えば，良くできる学生はどういう先生の下でも良くできるし，出来ない学生はどういう先生の下でも出来ない），っていう結果が出てくることが多いわけだけれど，これはちょっと皮肉な結果ではある。
