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 One RCT found a statistically significant positive effect of OLI on CAOS statistics scores (effect size 0.55, improvement index +21). → lovett-caos
q2 i? One quasi-experimental study found an indeterminate, non-significant negative effect on final exam scores (effect size -0.07). → schunn-final
q3 i? One RCT found indeterminate, non-significant positive effects on CAOS and final exam scores (effect sizes 0.08 and 0.11). → bowen-ach

WWC calculations from Lovett, Meyer, & Thille (2008), an RCT at Carnegie Mellon University with 61 students in an introductory statistics course. Intervention mean "68.00 (18.90)" versus comparison 53.00 (30.00), effect size 0.55, improvement index +21, p = .044, statistically significant.

q2 · i? · causal · r2
WWC calculations from Schunn & Patchan (2009), a quasi-experimental study of a symbolic logic course at Carnegie Mellon with baseline equivalence established. Final exam means "62.35 (22.71)" versus 64.13 (25.68), effect size -0.07, improvement index -3, p = .547, not significant.

WWC calculations from the Bowen et al. (2014) RCT: final exam effect size 0.11, improvement index +4, p = .248; the CAOS outcome in the same study showed effect size 0.08, +3, p = .420. Both characterized as indeterminate.
