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.

q2 i? Total effects of language, cognition, transcription, and reading comprehension differed substantially across writing quality, writing productivity, and correctness in writing. → Grace Kim Young-Suk & Graham Steve 2022

The article reports from its structural equation models of the Grade 2 sample that "Total effects of language, cognition, transcription, and reading comprehension varied largely for the three dimensions of written composition." No specific total-effect coefficients are printed in the available text.

"Total effects of language, cognition, transcription, and reading comprehension varied largely for the three dimensions of written composition."

Discussion¶

Learner Variables¶

Oral Language — predictor: learners who differ on it differ in outcomes
Reading and Language — predictor: learners who differ on it differ in outcomes
Writing Skills — predictor: learners who differ on it differ in outcomes

Reading comprehension is differentially correlated with the three dimensions of written composition in Grade 2: moderate relations with quality and correctness but weak relations with productivity — a narrower finding that bears on this claim
Reading comprehension differentially mediates the relations of discourse oral language and lexical literacy to writing quality in Grade 2 — related
Discourse oral language is strongly related to writing quality and reading comprehension but unrelated to writing productivity in Grade 2 — a narrower finding that bears on this claim
Kindergarten oral language is uniquely related to first-grade writing quality but not to compositional fluency — related
Discourse-level oral language, spelling, and handwriting fluency completely mediate the relations of language and cognitive skills to writing quality in Grade 1 — related
