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? CodingR accounted for significant variance in GORT-IV Fluency (R2 = .092, p = .027) and TOWRE PDE (R2 = .121, p = .011), with no significant CodingR-by-group interaction. → Jacobson 2011

Jacobson 2011¶
Jacobson, L. A., Ryan, M., Martin, R. B., Ewen, J., Mostofsky, S. H., Denckla, M. B., & Mahone, E. M. (2011). Working Memory Influences Processing Speed and Reading Fluency in ADHD. Child Neuropsychology. https://doi.org/10.1080/09297049.2010.532204
q3 · i? · associational · r2
Hierarchical regression in the same 62-child sample used a residualized Coding score controlling for sex and Coding Copy. "CodingR accounted for significant proportion of variance when predicting two of three measures of oral reading fluency"; the CodingR-by-group interaction was not significant, indicating a similar relationship in both groups.
"CodingR accounted for significant proportion of variance when predicting two of three measures of oral reading fluency: GORT-IV Fluency (R2 = .092, p = .027) and TOWRE Phonetic Decoding Efficiency (R2 = .121, p = .011)."
Discussion¶
Learner Variables¶
- Processing Speed — predictor: learners who differ on it differ in outcomes
- Reading Fluency — outcome: instruction changes it
