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 At immediate post-test, the pooled effect of morphology instruction on spelling outcomes was SMC/SMD = 0.38, statistically distinguishable from zero. → Danielle Colenbrander 2024

q3 · i1 · quant-synthesis · r3
RVE meta-analysis of 56 spelling effect sizes from 18 studies. The pooled spelling effect was "SMC/SMD = 0.38 for spelling (SE = 0.09; 95% CI = 0.18–0.58)", distinguishable from zero (p < 0.001).
"SMC/SMD = 0.38 for spelling (SE = 0.09; 95% CI = 0.18–0.58) and SMC/SMD = 0.13 for reading comprehension outcomes (SE = 0.09; 95% CI = -0.08–0.35)"
Discussion¶
Related Claims¶
- Effects of morphology instruction are large for directly trained words in both reading and spelling — a narrower finding that bears on this claim
- Transfer to untrained words occurs for spelling but not for reading outcomes — related
- Benefits of morphology instruction show little evidence of retention at follow-up, though follow-up data were sparse — related
- Morphological instruction improves word-level literacy outcomes (decoding, spelling, vocabulary, morphological knowledge) but shows no reliable effect on reading comprehension — a broader claim this one bears on
- No clear differential effects of morphology instruction by child factors: age, reading ability, SES, or linguistic background — related
- Morphology instruction produces small-to-moderate improvements in children's reading outcomes at immediate post-test — related
