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? Signing style (CM vs. EM) had no significant main effect on test scores and no significant interaction with time. → Rachel Sortino 2026
Evidence¶
Rachel Sortino 2026¶
Rachel Sortino, Christina Kim, Thalia Guettler, Katie McClyman, Lorna Quandt, Alicia Wooten & Rachel Pizzie. (2026). Producing concept-motivated signs supports learning of STEM content in American Sign Language. npj Science of Learning 11:37. https://doi.org/10.1038/s41539-026-00418-6
q3 · i? · causal · r2
Within-participant experiment (N = 30): an LMM testing style * time on test scores found no significant main effect or interaction, so "Watching lessons in the different signing styles did not have an impact on increases between pre- and post-test score".
"signing style did not have a signi ficant main effect on test scores, X2(1) = 0.32,p = 0.570. The interaction between signing style and time was also not significant,X2(1) = 0.35,p = 0.556."
Discussion¶
Related Claims¶
- Adult ASL-fluent participants significantly improved STEM test scores by about 22% after watching four-to-six-minute ASL video lessons — related
- Expert reviewers rated concept-motivated and English-motivated ASL lesson pairs as approximately equally clear, enjoyable, and frustrating — related
- Producing more concept-motivated signs in signed summaries predicted higher test scores, especially post-test, while English-motivated sign use did not — related
- Longer and more accurate signed summaries predicted higher post-test scores only for concept-motivated lessons, not English-motivated lessons — related
- Brief signed video lessons produced learning gains, but the study could not rule out practice effects because it lacked a no-training control group — a broader claim this one bears on
