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 Across 16 RCTs, interactive book-sharing interventions improved child receptive vocabulary relative to controls with a small pooled effect (d=0.26). → Dowdall 2020
Evidence¶
Dowdall 2020¶
Dowdall, N., Melendez-Torres, G. J., Murray, L., Gardiner, F., Harrtford, L. & Cooper, P.J. (2020). Shared picture book reading interventions for child language development: a systematic review and meta-analysis. Child Development, 91(2). https://doi.org/10.1111/cdev.13225
q3 · i1 · quant-synthesis · r3
Robust variance estimation meta-analysis of 16 RCTs providing 24 effect sizes from 1871 children. The pooled result showed "a small sized effect in improving receptive vocabulary when compared to controls" with d=0.26, CI 0.12-0.40, p=0.001, tau-squared=0.03.
"The pooled result of the robust variance estimation meta-analysis suggested evidence (p=0.001) for interactive book-sharing interventions having a small sized effect in improving receptive vocabulary when compared to controls (d=0.26; CI: 0.12, 0.40; df: 11.28); tau-squared = 0.03."
Discussion¶
Learner Variables¶
- Oral Language — outcome: instruction changes it
Related Claims¶
- Book-sharing interventions produce a large improvement in caregiver book-sharing competence (d=1.01) — related
- Child age, caregiver education and country income level do not moderate book-sharing intervention effects on child language — related
- Group-based delivery is associated with more improvement in child language than individually delivered interventions — related
- Improvements in caregiver book-sharing behaviour mediate the intervention's impact on child language (one mediation analysis) — related
- Intervention dosage moderates child language outcomes: brief interventions under 60 minutes show no significant effect — related
- Language and print knowledge instructional features produced statistically comparable performance within their domains, leaving unclear which features are most effective — related
