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? Based on two quasi-experimental studies, the WWC rates CIRC as having potentially positive effects on comprehension for adolescent learners. → Cooperative Integrated Reading and Composition® 2010
q2 i? The average improvement index for comprehension is +7 percentile points, with a range of +3 to +11 across findings from two studies; no standardised effect size is printed for this average. → Cooperative Integrated Reading and Composition® 2010
Evidence¶
Cooperative Integrated Reading and Composition® 2010¶
Cooperative Integrated Reading and Composition®. (2010). WWC Intervention Report, Adolescent Literacy. What Works Clearinghouse, U.S. Department of Education. https://ies.ed.gov/ncee/wwc/InterventionReport/111
q2 · i? · quant-synthesis · r1
Systematic review (WWC Adolescent Literacy protocol, Version 2.0) computing improvement indices from two quasi-experiments meeting standards with reservations. The report states the "average improvement index for comprehension is +7 percentile points"; the improvement index is a percentile-rank difference, not a standardised effect size, so impact is null.
"The average improvement index for comprehension is +7 per-centile points, with a range of +3 to +11 percentile points across findings from two studies."
