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? The experimental group receiving hierarchy vocabulary exercises significantly outperformed the control group receiving copying exercises on the immediate vocabulary post-test (t(54) = 2.380, p = .021). → Lin 2013

q2 · i? · causal · r2
Quasi-experiment with 56 Grade 5 students in Taiwan (27 experimental, 29 control), groups confirmed equivalent on prior English grades and pretest scores. Independent t-test on the immediate vocabulary post-test found the hierarchy group higher, "a significant difference between both groups (t (54) = 2.380, p =.021".
"For the scores on the immediate vocabulary post-test, the results showed that the mean of the experimental group (M = 88.81, SD = 17.94) was higher than that of the control group (M = 76.21, SD = 21.40). Besides, there was a significant difference between both groups (t (54) = 2.380, p =.021"
Discussion¶
Learner Variables¶
- Vocabulary — outcome: instruction changes it
