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? At delayed posttest the FCT group (84.78%) scored significantly higher than the CPA group (61.76%) and the control group (53.45%) on the focused communication task. → Broszkiewicz 2011
q3 i? At immediate posttest the difference between the two experimental groups approached but did not reach significance (F = 3.16, p = .08), with FCT at 89.06% and CPA at 78%. → Broszkiewicz 2011

q3 · i? · causal · r2
Analysis of pair recordings of a focused communication task, scoring obligatory contexts for the third conditional. The article concludes the FCT group "outperformed not only the control but also the CPA group during the test comprising a communication task"; the CPA group dropped almost 17% at delayed posttest, non-significantly.

Discussion¶
Related Claims¶
- The uninstructed control group showed a significant loss of over 30% on the paired focused communication task at immediate posttest, possibly reflecting fatigue with repetitive testing — related
- Instruction with focused communication tasks produced a significantly larger gain in implicit knowledge of past unreal conditionals than control instruction on an elicited imitation test — related
- 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
- All four written CF types, including metalinguistic code CF, outperformed the control group on the delayed posttest of implicit L2 knowledge. — related
