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.

q4 i3 Reading interventions seemed to have a better effect on word spelling (g = 0.93) than word reading (g = 0.63). → Yijun Ruan 2024

Evidence¶

Yijun Ruan 2024¶

Yijun Ruan, Urs Maurer, Catherine McBride. (2024). Effectiveness of Reading Interventions on Literacy Skills for Chinese Children with and Without Dyslexia: a Meta-analysis of Randomized Controlled Trials. Educational Psychology Review. https://doi.org/10.1007/s10648-024-09915-9

q4 · i3 · quant-synthesis · r?

Meta-regression on intervention outcome as moderator, based on 49 effect sizes (37 word reading, 12 word spelling) from the 28 RCTs. The article reports a larger effect for word spelling than word reading, hedged with "seemed to".

"Reading interven-tions seemed to have a better effect on word spelling (g = 0.93) than word reading (g = 0.63)."

Discussion¶

Learner Variables¶

Decoding — outcome: instruction changes it

Reading interventions significantly improve literacy skills of Chinese children overall (g = 0.68) — related
Transfer to untrained words occurs for spelling but not for reading outcomes — related
Instruction that includes systematic phonics leads to better spelling and reading outcomes than instruction that does not — a broader claim this one bears on
