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.
q1 i? Experimental group students used different strategies (cross-multiplication, creating equivalent fractions, unit fractions) with correct expressions, while control group students did not notice multiplicative relations and made incorrect additive solutions. → Şen 2017

q1 · i? · causal · r1
Qualitative analysis of homework problem-form solutions (Figures 1 and 2), presented as citations without scoring. The article reports that experimental students' solutions "support the scores they got from the PRT" and that control students' multiplicative relations were not noticed.
"It was observed that control group students made additive operations and that their solutions were incorrect since they could not notice ratio and proportional relations."
