Aiming for More Effective Recasts : Characteristics, Ambiguity and Uptake of Recasts

概要

A recast enables teachers to give feedback by reformulating a learner's immediately preceding utterance without interrupting the flow of the lesson, which is important especially in communicatively oriented classrooms. A great amount of recast studies unanimously find that recasts are the most frequently used corrective feedback and the efficacy of recasts is generally acknowledged. Nonetheless, the issue is still controversial. While some studies find recasts effective, others imply that recasts have little impact on second language acquisition. The aim of this paper is to investigate three of the potential factors that might account for these different findings on the effectiveness of recasts by reviewing the literature on recasts: the various definitions and operationalization of recasts, the ambiguity of recasts, and using uptake as a measure. This paper reviews findings from both experimental and observational studies that investigated the nature and roles of recasts in the second language education so that recasts can be used more effectively in real classrooms.
