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? When teachers' previous evaluation ratings were added to the statistical models, much of the principal-observer rating variation disappeared and the high-end difference was no longer statistically significant. → Sartain 2011

q2 · i? · associational · r3

Statistical re-analysis of the matched ratings showed that after controlling for prior checklist evaluation ratings, "much of the variation between principal and observer ratings disappeared," and the high-end difference "is no longer statistically significant." The authors offer two interpretations: principals may use historical knowledge or may rate more accurately.

"When we took into account teachers' previous evaluation ratings in the statistical models, much of the variation between principal and observer ratings disappeared."
