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 i1 In a randomized controlled trial with 20 dyslexic students in grades 4–6, Read Naturally® produced no statistically significant effects on either GORT-III Reading Accuracy or Reading Rate, and the WWC-calculated average effect size (domain average –0.16) was not substantively important. → Read Naturally® 2010

q3 · i1 · causal · r?
Randomized controlled trial (Chenault et al., 2006) reviewed under WWC standards: 20 dyslexic students in grades 4–6 randomly assigned to Read Naturally® or Pay Attention! in ten 25-minute sessions. The WWC confirmed "no statistically significant effects" on both GORT-III subtests; tabled effect sizes were –0.22 (Accuracy) and –0.11 (Rate), both ns, domain average –0.16, improvement index –6 percentile points.
"Chenault et al. (2006) found no statistically significant effects of Read Naturally ® on either of two measures of reading fluency: the Reading Accuracy and Reading Rate subtests from the Gray Oral Reading Test–III. The WWC confirmed these findings. Furthermore, the WWC-calculated average effect size across the two outcomes was not large enough to be considered substantively important."
