任务重复对二语口语产出影响的元分析

A Meta-Analysis of the Effectiveness of Task Repetition on L2 Oral Output

近20多年来,任务重复对二语口语产出的影响已成为二语习得领域的研究热点之一,但已有相关实证研究结果依然存在争议。本文运用元分析的方法对当前国内外相关实证研究进行系统梳理,分析任务重复对二语口语产出的总体效果及相关影响因素对二语口语产出的调节作用。结果显示:任务重复对二语口语产出有积极的促进作用;任务重复类型、重复间隔时间、任务时间限制、实验场所等因素对二语口语产出效果有不同程度的调节作用。最后,本研究提出任务重复的教学启示及未来该领域的研究方向。

Over the last two decades, the effectiveness of task repetition on L2 oral output has become a hot research topic in the field of SLA. However, controversy still exists in terms of the overall effectiveness and related moderators of task repetition on L2 oral output. This study, therefore, meta-analyzes the extant research to investigate the influence of task repetition on L2 oral output and how the moderators affects its effectiveness. The results reveals that task repetition is facilitative for L2 oral output;repetition types, repetition intervals, time limits and research environment show differential moderating effects on L2 oral output. The study also outlines possible pedagogical implications and directions for future research.
