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 i2 Across two studies totaling 712 students, CIRC showed a statistically significant positive effect in one study and an indeterminate effect in another, yielding a domain rating of potentially positive effects for comprehension. → wwc-summary-1
Evidence¶
wwc-summary-1¶
U.S. Department of Education, Institute of Education Sciences, What Works Clearinghouse. (2012, June). Beginning Reading intervention report: Cooperative Integrated Reading and Composition®. https://ies.ed.gov/ncee/wwc/InterventionReport/109
q3 · i2 · quant-synthesis · r1
WWC synthesis of two studies (one RCT, one quasi-experiment) covering 712 students in grades 3 and 4 in Ohio and Pennsylvania. Table 1 reports an average comprehension improvement index of +12 (range +1 to +30) and a medium to large extent of evidence; the domain average effect size across studies was 0.31.
"Cooperative Integrated Reading and Composition ® was found to have potentially positive effects on comprehension and no discernible effects on general reading achievement for beginning readers."
