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.

q3 i? Differences in observation scores by school poverty level are more pronounced than differences in value-added scores, with a moderate negative correlation between observation scores and school economic disadvantage. → Jiang 2016

q2 i? 30 percent of the lowest-scoring teachers on observations are in the highest-poverty schools, while only 9 percent are in the lowest-poverty schools, a more pronounced imbalance than for value-added scores. → Jennie Y. Jiang 2016

Evidence

Jiang 2016

Jiang, J. Y., & Sporte, S. E. (2016). Teacher Evaluation in Chicago: Differences in Observation and Value-Added Scores by Teacher, Student, and School Characteristics. UChicago Consortium on School Research. https://eric.ed.gov/?id=ED562786

q3 · i? · associational · r2

Descriptive correlational analysis of 2013-14 CPS observation scores aggregated to the school level, finding a "moderate negative correlation (-0.33) between observation scores and the concentration of economically disadvantaged students in schools." Value-added differences by poverty are much smaller because value-added controls for student characteristics.

"There is a moderate negative correlation (-0.33) between observation scores and the concentration of economically disadvantaged students in schools."

q2 · i? · associational · r2

Same observational analysis of REACH Students data. Observation-score concentration across poverty levels is steeper than for value-added: of the teachers with the lowest observation scores, 30 percent are in the highest-poverty schools and 9 percent in the lowest-poverty schools.

"The differences in observation scores by school poverty level are more pronounced. Of the teachers with the lowest scores on observation ratings, 30 percent are in schools with the highest poverty while only 9 percent are in schools with lowest poverty"
