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 i3 After five weeks, science achievement differed significantly across groups, with a large effect (partial eta-squared ƞ2=.147). → Celal Boyraz 2017 q3 i3 Experiment 2 (concepts during activities) and Experiment 3 (concepts at end) scored significantly higher than the control group, with large Cohen's d values (d=0.95 and d=0.87). → Celal Boyraz 2017 (2)

q3 · i3 · causal · r1

One-way ANOVA on achievement posttest scores of 82 third graders in three experimental GPA-based groups and one control group after a five-week intervention; the article reports F(3, 78)=4.486, p<.05, partial eta-squared ƞ2=.147, which it characterizes as a "large" effect, with statistical power .87.

"The results of the analysis showed that there was a significant difference between science achievement of the groups, F(3, 78)=4.486, p<.05, ƞ2=.147."

q3 · i3 · causal · r1

Bonferroni post-hoc comparisons on the achievement posttest found the control group significantly lower than Experiment 2 (Cohen's d=0.95) and Experiment 3 (Cohen's d=0.87); the article characterizes both effect sizes as large in favour of the experimental groups.

"Accordingly, it was found as d=0.95 for the control and Experiment 2 groups, while it was d=0.87 for the control and Experiment 3 groups."
