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? Blinded classroom observations found significantly higher levels of positive interdependence in intervention schools (F(1,98) = 10.79, p < .01, R2 = .10). → Van Ryzin 2018

Van Ryzin 2018¶
Van Ryzin, M. J., & Roseth, C. J. (2018). Cooperative Learning in Middle School: A Means to Improve Peer Relations and Reduce Victimization, Bullying, and Related Outcomes. Journal of Educational Psychology, 110(8), 1192-1201. https://doi.org/10.1037/edu0000265
q3 · i? · causal · r2
Research staff blind to intervention assignment observed classrooms twice (late fall/early winter and spring) using an established cooperative-learning observation protocol; ANOVA confirmed implementation fidelity in the trial, with R2 = .10 as printed and no standardized effect size reported.
"With regards to fidelity observations, ANOVA indicated significantly higher levels of observed positive interdependence in intervention schools as compared to control schools, F(1,98) = 10.79, p < .01, R2 = .10."
