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? Shared book reading with questions (0.26) and without questions (0.09) both yielded significant, statistically comparable language improvements. → Sarah Herrera 2021

q3 · i? · quant-synthesis · r2

Weighted effect size comparison in table B8 between language interventions using shared book reading with implementer questions versus without questions. Both types yielded "significant and statistically comparable improvements in language performance (0.26 versus 0.09)," though the review notes it remains unclear which features are most effective.

"Both types of shared book reading yielded significant and statistically comparable improvements in language performance (0.26 versus 0.09; see table B8 in appendix B)."
