Abstract
The current study compared the effectiveness of recasts which triggered learners’ modification to their incorrect forms with recasts which triggered no modified output. To this end, 60 Iranian EFL learners randomly selected from two EFL classes received recasts for their errors during task-based interactions with their interlocutors. Using a tailor-made design, we compared the efficacy of recasts which were followed by learners’ modified output with the efficacy of recasts which triggered no modified output. The results indicated that recasts which were followed by learners’ modified output were more effective than recasts which prompted no modified output on promoting L2 development.
Highlights
Second language (L2) acquisition research over the past decade has investigated what type of instruction best promotes the acquisition of L2 knowledge
The current study investigated the effects of learners’ modified output on the efficacy of recasts
Our research question asked: Does learners’ ability to modify their incorrect utterances following recasts promote the efficacy of recasts? The results of descriptive statistics for learners’ performance on tailor-made post-tests revealed that the rate of development in recasts episodes which were accompanied by learners’ modified output was higher than those recasts episodes with no modified output. These accuracy rates turned out to be significant when submitted to paired t-tests. Such a trend was observed for all four structures which were targeted in the current study
Summary
Second language (L2) acquisition research over the past decade has investigated what type of instruction best promotes the acquisition of L2 knowledge. The most comprehensive taxonomy of corrective feedback has been provided by Lyster and Ranta (1997) who classified corrective feedback into six categories: explicit correction, recast, metalinguistic feedback, elicitation, repetition, and clarification request. Among these categories, recasts will be considered in the current study. An example of a recast adapted from Sheen (2007) is given below
