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.

q3 i? The experimental (CALL-based task) group scored significantly higher than the control (written questions) group on the grammar post-test (17.45 vs 15.60). → Alian 2018

q3 · i? · causal · r2

Quasi-experiment with 60 Iranian junior high learners (30 per group) taught six grammar topics over 15 sessions; the post-test comparison favored the CALL-based task group, with means of 17.45 and 15.60 and a significant independent samples t-test ("t = 25.869, p = .000").

"independent samples test showed significant difference in grammar learning between the two groups (experimental and control groups) on post-test with (t = 25.869, p = .000, p < α)"
