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? Experimental group students scored significantly higher on the post-test than control group students (p = 0.047). → Özdemir et al. 2015

Quasi-experimental pre/post control-group study of 70 7th graders (36 experimental, 34 control) taught the same unit over 7 weeks. The unrelated t-test found a meaningful difference in favor of the experimental group, whose post-test mean was 16.47 versus 14.15 for the control group.
"According to the results of the unrelated t-test (Tab le 2), (p = 0,047 < 0,05) which was used to search whether there is a meaningful difference between th e post-test scores of control and experimental group students"
Discussion¶
Learner Variables¶
- Proportional Reasoning — outcome: instruction changes it
