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? Comparisons of guessing responses between experimental and comparison groups showed no evidence of learned generalizations to novel stimuli. → Susanne Carroll 1992

Evidence¶

Susanne Carroll 1992¶

Susanne Carroll, Merrill Swain, and Yves Roberge. (1992). The role of feedback in adult second language acquisition: Error correction and morphological generalizations. Applied Psycholinguistics, Volume 13, Issue 2. https://doi.org/10.1017/S0142716400005555

q3 · i? · causal · r?

After the feedback session, all subjects guessed responses to novel stimuli and were retested twice on the feedback items. The abstract reports that comparisons of guessing responses between experimental and comparison groups "showed no evidence of learned generalizations"; no test statistic or effect size is printed.

"Afterward, all subjects “guessed” responses to novel stimuli and were retested (twice) on the feedback items."

Discussion¶

Learner Variables¶

Morphological Awareness — outcome: instruction changes it

Explicit L2 grammar instruction leads to larger learning effects than implicit instruction, as reported in the reviewed synthesis literature — the general claim this finding bears on, with the studies behind it
Explicit correction improves adult L2 learners' responses on corrected suffixation items during the feedback session — 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
Metalinguistic feedback and recasts, but not clarification requests, significantly improve Iranian EFL learners' wh-question performance on an immediate post-test — related
Learning of absolute exceptions in French suffixation was more likely among advanced than intermediate adult learners — related
On the immediate posttest of explicit L2 knowledge, direct CF and metalinguistic CF with rule explanations outperformed the control group while metalinguistic code CF did not. — related
