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? Mixed ANOVA showed a significant main effect of time but no significant interaction between time and grouping (treatment/control). → Fatma Aslan-Tutak and Thomasenia Lott Adams 2015

Evidence

Fatma Aslan-Tutak and Thomasenia Lott Adams 2015

Fatma Aslan-Tutak and Thomasenia Lott Adams. (2015). A Study of Geometry Content Knowledge of Elementary Preservice Teachers. International Electronic Journal of Elementary Education, 7(3), 301-318. https://eric.ed.gov/?id=EJ1068059

q2 · i? · causal · r1

Mixed ANOVA comparing treatment (n=54) and control (n=48) groups' pre/post CKT-M geometry scores found "no significant interaction between time and grouping"; equivalence was not tested. The article reports no effect size for the interaction.

"Results indicated a significant main effect of time F(1, 91) = 28.38, p<.001 but there was no significant interaction between time and grouping (treatment/control), F(1, 91) = .21, p=.646."
