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 i? Correct responses per minute (RPM) over the 3-minute tablet session was highly reliable (r = 0.97) and 3 minutes of single-digit fluency data explained roughly 36% of variance in SBAC standardized math scores. → Ethan Roy 2025

q3 · i? · design · r2

Reliability analysis of the tablet-based single-digit fluency module in the study's cohort of 3rd, 5th, and 7th graders. The article reports "RPM proved highly reliable (r = 0.97)" across the 3-min session, with r = 0.95 for 2 min and r = 0.92 for 1 min of data; no standardized effect size is printed.

"Across the entire 3-min session, RPM proved highly reliable (r = 0.97; Fig. 1, left panel)."

q3 · i? · associational · r3

Criterion validity analysis predicting Smarter Balanced (SBAC) math scores from RPM. The article reports that "3 min of single-digit fluency served to explain roughly 36% of the variance in standardized test scores", with first-minute and 2-minute subsets explaining over 24% and 32% respectively; variance explained is not treated as an effect size.

"We found that 3 min of single-digit fluency served to explain roughly 36% of the variance in standardized test scores (Fig.1, right panel)."

Discussion¶

RPM fluency metrics predict standardized math achievement better than traditional raw scores, with common-problem RPM the strongest predictor — related
