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? A two-factor model of narrative and expository writing quality fit better than a single-factor model (Δχ²[Δdf = 1] = 18.99, p < .001), with the two factors correlated r = .70. → Kim Young-Suk 2015

q3 · i? · associational · r2
Confirmatory factor analysis of third-grade writing quality ratings (idea development and organization, kappa .82–.88) from the 157-child sample. The quote reports the two-factor superiority test and the r = .70 correlation between factors.
"measurement models indicated that a two factor model of narrative writing quality and expository writing quality was superior to a single factor model of overall writing quality (ΔX2 [Δdf = 1] = 18.99, p < .001). Narrative writing quality and expository writing quality were fairly strongly related (r = .70)"
Discussion¶
Related Claims¶
- Kindergarten lexical literacy (word reading and spelling) predicts third-grade writing quality in both narrative and expository genres — related
- Preschool emergent writing skills are best described by three correlated but distinct factors: Conceptual Knowledge, Procedural Knowledge, and Generative Knowledge — related
- Kindergarten oral language does not uniquely predict third-grade expository writing quality — related
- Kindergarten oral language independently predicts third-grade narrative writing quality — related
- Written composition quality is best described as a single unidimensional construct across English and Spanish and across narrative and opinion genres for primary-grade dual language learners — reports the opposite
