Subclaims¶

q3 i? Neither the WRMT–R passage comprehension subtest (ES 0.06) nor the GRADE passage comprehension subtest (ES 0.28) showed a statistically significant effect; the domain average (0.17) was not significant or substantively important. → Corrective Reading—What Works Clearinghouse Intervention Report 2007

q3 · i? · causal · r2

In the Torgesen et al. (2006) randomized controlled trial, both comprehension outcomes were non-significant; Appendix A3.3 shows effect sizes of 0.06 (WRMT–R) and 0.28 (GRADE), a domain average of 0.17, and improvement indices of +2 and +11. Equivalence was not tested.

"Torgesen et al. (2006) examined two outcomes in this domain (WRMT–R passage comprehension subtest and the Group Reading Assessment and Diagnostic Evaluation (GRADE) passage comprehension subtest) and reported no statistically significant effects."
