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? Impacts of the teacher treatment and the parent-and-teacher combined treatment on learning summary, literacy, and numeracy were statistically insignificant; the estimates were negative for the summary measure and literacy (d = −0.019 to −0.073) and near zero for numeracy (0.000 teachers-only, 0.011 combined). → Sharon Wolf and Guilherme Lichand 2023

q3 · i? · causal · r3

Same school-randomized trial (2246 observations, school-clustered SEs). The article's text describes the teacher-only and combined arms as "statistically insigni ficant and negative" on all three learning outcomes, but its Table 1 gives negative estimates only for the learning summary (teachers −0.037, p = 0.449; both −0.019, p = 0.673) and literacy (teachers −0.073, p = 0.234; both −0.049, p = 0.382); numeracy was 0.000 (p = 0.996) for teachers-only and 0.011 (p = 0.811) for the combined arm. Non-significance here does not show the impacts are zero.

"Impacts of the teacher treatment and of the parent and teacher combined treatment on all three outcomes were also statistically insigni ficant and negative ( d = −0.019 to −0.073)."
