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? Math placement, SAT math, and SAT verbal scores were significantly lower for underprepared students than college-ready students at course entry. → Hesser 2016

q3 · i? · causal · r1
Independent-sample t-tests on entrance measures confirmed group nonequivalence: math placement t(268) = -14.66, p < .001 (M = 52.88 vs 87.14); SAT math t(254) = -2.76, p < .05 (M = 538.7 vs 568.0); SAT verbal t(254) = -2.27, p < .05 (M = 509.2 vs 534.0). The authors state these results "supported the placement of these students into a course with added instructional support."
"Overall, the analysis of entrance exam scores indicated that students labeled as underprepared had entrance assessment averages significantly lower than the averages of college-ready students when entering the General Chemistry course."
Discussion¶
Related Claims¶
- Underprepared students scored significantly lower on early-semester common questions, validating their need for support — a narrower finding that bears on this claim
- Underprepared students in embedded-support chemistry showed no statistically significant difference from college-ready peers on overall common-question results — related
- The treatment groups showed no pre-existing differences on college GPA, high school GPA, class rank, or SAT scores — related
- No significant difference between underprepared and college-ready students on final exam multiple-choice questions — related
- After approximately 12 weeks of embedded support, underprepared students significantly outperformed college-ready peers on late-semester common questions — related
