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? The general oral language factor significantly predicted latent reading comprehension in all grades, with standardized coefficients from 0.72 to 0.96, and the latent factors of oral language and decoding fluency together (not oral language alone) accounted for 72%–99% of comprehension variance; decoding fluency made no significant unique contribution in any grade. → Foorman Barbara R. 2015

q2 · i? · associational · r2
Structural equation modeling by grade tested direct effects of the general oral language, specific syntax and vocabulary, and decoding fluency factors on latent reading comprehension; the article reports standardized coefficient estimates "ranging from 0.72 to 0.96" and that "the amount of variance in reading comprehension that the latent factors of decoding fluency and oral language accounted for was between 72% and 99%" — a figure for the model's factors together, not for the general oral language factor alone.
"The general oral language factor, measured both by syntax and vocabulary indicators, significantly predicted reading comprehension in all grades, with standardized coefficient estimates ranging from 0.72 to 0.96"
Discussion¶
Learner Variables¶
- Communication Skills — predictor: learners who differ on it differ in outcomes
- Oral Language — predictor: learners who differ on it differ in outcomes
- Reading and Language — predictor: learners who differ on it differ in outcomes
- Syntax — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Specific syntax and vocabulary factors uniquely predicted reading comprehension in only one grade each (syntax in 4th, vocabulary in 7th) — a narrower finding that bears on this claim
- Oral language measures of syntax, listening comprehension, and oral vocabulary do not predict which English learners will struggle with learning to read — reports the opposite
- In French first-graders, a three-factor structure distinguishing lower level language skills from discourse skills fits better than a two-factor oral language structure at both the beginning and end of first grade — related
- Non-LEP students outperformed LEP-designated students on oral language, reading comprehension, and decoding fluency factors with large effect sizes in grades 5 and 7 — related
