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 Each intervention condition outperformed CON on NAEP fraction knowledge, number line, and calculations (ESs 0.57–1.98 for EXP; 0.70–2.08 for WP). → Fuchs 2016

q3 · i3 · causal · r2
1-way ANCOVAs on NAEP, Fraction Number Line, and calculation posttests controlling pretest, replicating the multi-component intervention's efficacy. The article reports effect sizes: "ESs favoring EXP over CON ranged from 0.57 to 1.98" and "ESs favoring WP over CON ranged from 0.70 to 2.08" (ES = 0.57 to ES = 2.08).
"NAEP, number line, and calculations performance was stronger for each intervention condition compared to CON. ESs favoring EXP over CON ranged from 0.57 to 1.98; ESs favoring WP over CON ranged from 0.70 to 2.08."
