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.
q2 i? Corrective Reading had a statistically significant positive effect on alphabetics for students with high pretest PPVT scores and no effects for students with low pretest PPVT scores. → Corrective Reading—What Works Clearinghouse Intervention Report 2007
q2 i? Statistically significant positive effects on TOWRE sight word efficiency and oral fluency appeared for students not eligible for free/reduced lunch but not for eligible students. → Corrective Reading—What Works Clearinghouse Intervention Report 2007 (2)
q2 i? No differences were found for alphabetics or fluency outcomes as a function of students' initial word attack scores. → Corrective Reading—What Works Clearinghouse Intervention Report 2007 (3)
Evidence¶
Corrective Reading—What Works Clearinghouse Intervention Report 2007¶
Corrective Reading—What Works Clearinghouse Intervention Report. (2007). U.S. Department of Education, What Works Clearinghouse. https://www.ed.gov/rschstat/eval/disadv/title1interimreport/index.html
q2 · i? · causal · r2
Subgroup analyses by initial skill level and socioeconomic status reported in the footnotes to the WWC findings tables for the Torgesen et al. (2006) trial; no effect sizes are printed for the subgroup contrasts.
"The study reported that Corrective Reading had a statistically significant positive effect on alphabetics for students with high pretest PPVT scores and no effects on students with low pretest PPVT scores."
Corrective Reading—What Works Clearinghouse Intervention Report 2007 (2)¶
Corrective Reading—What Works Clearinghouse Intervention Report. (2007). U.S. Department of Education, What Works Clearinghouse. https://www.ed.gov/rschstat/eval/disadv/title1interimreport/index.html
q2 · i? · causal · r2
Socioeconomic-status subgroup analysis from the same trial, reported in the alphabetics findings footnote; the fluency footnote reports the same pattern for the Oral Fluency Test. No subgroup effect sizes are printed.
"An additional subgroup analysis found statistically significant positive effects on the TOWRE sight word efficiency subtest for students not eligible for the free/reduced lunch program, but not for students eligible for the free/reduced lunch program."
Corrective Reading—What Works Clearinghouse Intervention Report 2007 (3)¶
Corrective Reading—What Works Clearinghouse Intervention Report. (2007). U.S. Department of Education, What Works Clearinghouse. https://www.ed.gov/rschstat/eval/disadv/title1interimreport/index.html
q2 · i? · causal · r2
Initial-skill-level subgroup analysis reported in the alphabetics findings footnote of the WWC report; the fluency footnote likewise states no differences between initial skill level subgroups for fluency.
"The study found no differences for alphabetics outcomes as a function of students’ initial level of word attack scores."
