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? There were no significant effects of IY TCM on disruptive behavior or concentration problems. → Reinke 2014

Evidence

Reinke 2014

Reinke, W. M., Herman, K. C., & Dong, N. (2014). The Incredible Year Teacher Classroom Management Program: Initial Findings from a Group Randomized Control Trial. SREE Spring 2014 Conference. https://eric.ed.gov/?id=ED563013

q3 · i? · causal · r2

Null findings from the same hierarchical model analyses in the cluster randomized trial; baseline disruptive behavior was low (M=1.77 on a 1-6 scale, "a full standard deviation below mean levels observed in other samples"). No effect size printed; equivalence was not tested.

"However, there were no significant effects of IY TCM on disruptive behavior or concentration problems. The null findings on disruptive behaviors were likely an artifact of the low rates of disruptive behaviors across all classrooms at baseline"
