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? Teachers reported significant pre-post growth in bilingual literacy strategies for mathematics, writing about mathematics, mathematics vocabulary instruction, and modeling bilingual instruction after LSVC participation. → Yuzhu Xia 2025

q2 · i? · design · r2

Paired-sample t-tests on baseline and follow-up surveys from 57 of 71 teacher participants in three cohorts (2018–2021), with Bonferroni correction for multiple comparisons. Descriptive gains included "explicitly taught mathematics vocabulary (Δ = 0.56)"; no standardized effect sizes were printed.

"On a 1–5 scale, participants reported increased implementation of bilingual literacy strategies to strengthen students’ comprehension of mathematics (Δ = 0.70), provided more opportunities for students to write about mathematics (Δ = 0.56), explicitly taught mathematics vocabulary (Δ = 0.56), and fostered bilingual students’ communication of mathematical ideas (Δ = 0.40)."
