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 i3 The DR, MS and MN groups scored significantly higher than the CO group on the immediate dictogloss writing posttest with large effect sizes, while the MC group did not. → Jang 2020

Tukey post-hoc results for dictogloss writing accuracy, the measure of implicit knowledge, in the four-session experiment. The study reports the groups "other than the MC group outperformed the CO group on the immediate posttest with large effect sizes".
"All the experimental groups other than the MC group outperformed the CO group on the immediate posttest with large effect sizes (d = 1.527 for DR; d = 1.573 for MS; d = 1.064 for MN)."

- All four written CF types, including metalinguistic code CF, outperformed the control group on the delayed posttest of implicit L2 knowledge. — related
- Metalinguistic written CF was equivalent, not superior, to non-metalinguistic direct CF, contrasting with previous studies whose metalinguistic CF also contained correct forms. — related

- Corrective feedback facilitates L2 grammatical development, with explicit feedback stronger immediately and implicit feedback better maintained over time — a broader claim this one bears on
- Corrective feedback on second-language errors has a significant effect on L2 development that is maintained on delayed tests — a broader claim this one bears on
