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 i3 In a randomized study across three school settings, grade 4 and grade 6 students taught by CRISS-trained teachers showed significantly greater gains on a staff-developed free-recall assessment than control students. → Project CRISS® (CReating Independence through Student-owned Strategies) 2010

q3 · i3 · causal · r2
Random assignment study in which teachers within each school were assigned to Project CRISS® or regular instruction; the WWC rated effectiveness on 120 CRISS students and 111 control students in grades 4 and 6 after approximately 18 weeks. Appendix A3 prints effect sizes of 1.17 (grade 4) and 0.96 (grade 6), both statistically significant, with improvement indices of +38 and +33. The report states students "demonstrated significantly greater gains in a staff-developed CRISS free-recall assessment than comparison students."
"Horsfall and Santa (1994) reported, and WWC calculations confirmed, that students in the Project CRISS® condition demonstrated significantly greater gains in a staff-developed CRISS free-recall assessment than comparison students in the 4th and 6th grades."
