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 i1 After controlling for demographics and school fixed effects, treatment students scored 0.197 SDs above their grade-specific mean on the overall ELPAC relative to comparison students. → Nicholas Feroce 2025

Nicholas Feroce, Jenny Liu, Rajendra Chattergoon. (2025). Exploring the impact of a CALL tool for emergent bilinguals. Education Tech Research Dev. https://doi.org/10.1007/s11423-025-10462-5
q3 · i1 · causal · r2
Quasi-experimental regression analysis of spring 2021 ELPAC scores for 2034 K-5 ELs (1478 treatment, 556 comparison) in one California district. The article reports the Lexia English coefficient as 0.197*** (SE 0.051) and interprets SD units as comparable to effect sizes, i.e. an effect size of 0.197 SDs, a small significant effect.
"For the overall ELPAC, students who used the CALL program were predicted to score, on average, 0.197 SDs above their grade-specific mean after controlling for student demographics and school-related differences, compared to students who did not use the program."
Discussion¶
Learner Variables¶
- English-Learner Status — outcome: instruction changes it
Related Claims¶
- Effects of CALL program use varied by grade, with significant effects for grades 2 and 5 on overall and written scores and for grades 2, 4, and 5 on oral scores — related
- Proficiency-level analyses found no significant differences between program users and non-users in odds of attaining ELPAC proficiency — reports the opposite
- Program use was associated with significant gains on both ELPAC subdomains, with a larger effect for the oral subdomain (0.224 SD) than the written subdomain (0.153 SD) — related
