Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? The correlation between teacher effectiveness for Black students and for non-Black students was between 0.28 and 0.67, depending on subject and grade level, so overall effectiveness can obscure differential effectiveness for Black students. → Delgado 2023
Evidence¶
Delgado 2023¶
Delgado, W. (2023). Is the Best Teacher the Best for Everyone? Variation of Teacher Effectiveness by Student Race. Chicago, IL: University of Chicago Consortium on School Research. https://consortium.uchicago.edu/publications/is-the-best-teacher-the-best-for-everyone
q2 · i? · causal · r?
Value-added analysis of Chicago Public Schools data estimating race-specific teacher effects; the brief reports correlations "between 0.28 and 0.67" across subject and grade level, meaning teachers more effective for Black students were often, but not always, more effective for non-Black students.
"The correlation between teacher effectiveness for Black students and effectiveness for non-Black students was between 0.28 and 0.67 (on a scale where zero means no relationship and 1.0 means a perfect relationship), depending on the subject and grade level."
Discussion¶
Learner Variables¶
- Race and Ethnicity — moderator: an instructional effect differs by group
Related Claims¶
- Experienced teachers and teachers with a master's degree are highly effective overall but much less effective for Black than non-Black students — related
- Observation scores are modestly positively associated with individual value-added (adjusted correlation 0.349) but only weakly associated with performance tasks (0.108) and school-wide literacy value-added (0.119) — related
- Race-specific value-added scores predict teachers' subsequent effects: Black students taught by a teacher with high prior effectiveness for Black students show gains of about one standard deviation when the teacher moves schools or grades — related
