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? Children's vocabulary was not uniquely related to either the substantive quality or writing conventions outcome after accounting for instructional quality variables and other child-level variables (ps ≥ .54). → Kim 2013
Evidence¶
Kim 2013¶
Kim, Y.-S., Al Otaiba, S., Sidler Folsom, J., & Gruelich, L. (2013). Language, literacy, attentional behaviors, and instructional quality predictors of written composition for first graders. Early Childhood Research Quarterly, 28(3), 461–469. https://doi.org/10.1016/j.ecresq.2013.01.001
q3 · i? · associational · r2
Null finding from the multilevel models: expressive vocabulary (WJ-III Picture Vocabulary) showed no unique relation to either written composition dimension once grammatical knowledge, reading, spelling, letter writing automaticity, attentiveness, and instructional quality were accounted for.
"Children's vocabulary was not uniquely related to either of the writing outcomes after accounting for instructional quality variables and other child-level variables in the model (ps ≥ .54)."
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
- Vocabulary — predictor: learners who differ on it differ in outcomes
- Writing Skills — outcome: instruction changes it
