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.

q2 i? A randomized controlled trial with compromised random assignment (36 math-talented eighth graders) showed no statistically significant difference between UCSMP Algebra and comparison groups in the algebra domain (average improvement index –6). → What Works Clearinghouse 2016

q2 · i? · causal · r1

WWC review of Peters (1992), an RCT in one Nebraska junior high school in which 17 UCSMP Algebra students were compared with 19 Saxon Algebra I students; the study finding table prints an improvement index of "–6" and "No" statistical significance, characterized as an indeterminate effect.

"Peters (1992) found, and the WWC confirmed (using a difference-in-differences approach), no statistically significant differences between the UCSMP Algebra and comparison groups in the algebra domain."
