q3 i? On the delayed grammaticality judgment posttest, the metalinguistic group differed significantly from the recast group, with a trend toward metalinguistic over control. → Rod Ellis 2006

q3 · i? · causal · r1

ANCOVA on the untimed grammaticality judgment test (a measure of explicit knowledge) at delayed posttest for the same 34 learners. "the metalinguistic group differed significantly from the recast group" with F (2, 34) = 4.493, p < .05.

"there is for the delayed posttest, F (2, 34) = 4.493, p < .05. The post hoc contrasts for the delayed posttest showed that the metalinguistic group differed significantly from the recast group and that there was a trend toward significance for metalinguistic over the control."

Related Claims¶

• Corrective feedback on second-language errors has a significant effect on L2 development that is maintained on delayed tests — the general claim this finding bears on, with the studies behind it
• Explicit metalinguistic feedback outperforms recasts on the delayed oral imitation posttest measuring implicit knowledge — related
• Metalinguistic feedback's gains on wh-question performance decline over a ten-day delay while recast gains hold, leaving the two no different — related
• Metalinguistic feedback produced system learning, generalizing to verbs not included in the treatment — related
• Metalinguistic feedback outperforms recasts on the immediate post-test, but the two do not differ significantly on the delayed post-test — reports the opposite
• No group differences on immediate posttests for either feedback type on either measure — related
• Prompts were overall more effective than recasts as corrective feedback for L2 grammar learning — related
