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? Post-test problem solving skills scores of the Layered Curriculum experimental group were significantly higher than those of the control group taught with the existing curriculum. → Koc Akran 2019
Evidence¶
Koc Akran 2019¶
Koc Akran, S., & Gurbuzturk, O. (2019). Effect of layered curriculum in problem solving skills of students in science and technology course. International Journal of Educational Methodology, 5(1), 135-150. https://doi.org/10.12973/ijem.5.1.147
q2 · i? · causal · r1
Between-group t-test on post-test scores of 30 experimental versus 30 control students. Experimental post-test mean was 85,28 versus control 75,88 out of 100; the comparison is significant with no printed effect size.
"there is a significant differentiation between post-test problem solving skills point average of experimental group students who were subjected to Layered Curriculum activities and that of control group students who were not subjected to Layered Curriculum activities [t(58)= 8,787; p<0.05]"
Discussion¶
Learner Variables¶
- Problem Solving — outcome: instruction changes it
