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? In step 3 of the hierarchical regression, phonological processing accounted for 38.3% of added variance in literacy, and the full model accounted for 76.7% of variance including early reading level. → Geers Ann E.; Hayes Heather 2011

q2 · i? · associational · r2
Hierarchical multiple regression predicting the literacy factor score in 112 CI-HS students (Table 4). "Phonological processing accounted for 38.3% of added variance in literacy level" in step 3; CI-E reading level added 10% in step 4, for a total R2 of 0.767. The phonological contribution was independent of performance intelligence.
"Phonological processing accounted for 38.3% of added variance in literacy level. Thus, not only were phonological processing skills highly related to one another"
Discussion¶
Learner Variables¶
- Phonological Awareness — predictor: learners who differ on it differ in outcomes
