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.
q4 i2 In one RCT meeting WWC standards without reservations, Fraction Face-Off! produced a positive and statistically significant effect on general mathematics achievement measured by NAEP selected items (effect size 0.64, improvement index +24, 1,152 students). → naep-1

Findings from the one RCT meeting WWC standards without reservations, using a collection of 19 researcher-selected items from the 1990-2009 NAEP fourth-grade assessment with 1,152 fourth-grade students. The intervention group mean was 14.83 versus 12.36 for comparison, effect size 0.64, p < .01.
