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? Moderator analyses found no statistically distinguishable differences by linguistic background, SES, reading/spelling ability, school grade, group size, or intervention type. → Danielle Colenbrander 2024

q3 · i? · quant-synthesis · r3
Pre-specified moderator analyses across 172 effect sizes found "effect sizes for different subgroups were not statistically distinguishable from zero, and robust HTZ-type Wald tests comparing the sizes of effects were not significant (p > 0.05)" for linguistic background, SES, ability, grade, group size, and intervention type.
"For almost all moderators, effect sizes for different subgroups were not statistically distinguishable from zero, and robust HTZ-type Wald tests comparing the sizes of effects were not significant (p > 0.05)"
Discussion¶
Learner Variables¶
- Reading and Language — moderator: an instructional effect differs with it

- Morphology instruction produces small-to-moderate improvements in children's spelling outcomes at immediate post-test — related
- Morphological instruction improves word-level literacy outcomes (decoding, spelling, vocabulary, morphological knowledge) but shows no reliable effect on reading comprehension — related
- Transfer to untrained words occurs for spelling but not for reading outcomes — related
