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? Level II learners in the experimental group using the Wikipedia Corpus achieved significantly greater lexical gains than Level II learners in the control group. → Shi 2015

q2 · i? · causal · r1
A quasi-experiment with 48 first-year English majors assigned to experimental (corpus-based) and control (conventional) groups over one semester. The author reports that for Level II learners, "learners in Level II in the experimental group did better than those in the control group, and the difference is statistically significant." No effect size is printed.
"Second, learners in Level II in the experimental group did better than those in the control group, and the difference is statistically significant. Medium-level learners welcome the innovative method and they find it easy to adapt to the new method."
