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
