修正性反馈在中国外语学习者感知和产出英语松紧元音对中的影响研究

A Study on the Impacts of Corrective Feedback on Perception and Production of English Tense-lax Vowel Contrast by Chinese EFL Learners

本研究检测了修正性反馈在英语松紧元音对/i/-/I/感知和产出中的影响。100名非英语专业大一新生随机被分为重铸组、引导组、引导+重铸组及控制组,进行前测,6轮基于感知的任务型交互活动,即时后测和延时后测。前、后测分别包括感知测试,控制型产出测试和自发型产出测试。结果显示:1)感知方面,在已训和未训词汇条件下,重铸、引导、引导+重铸在英语松紧元音对/i/-/I/的感知中均发挥了显著效应,且三类修正性反馈的有效性无显著差异;2)产出方面,在已训和未训词汇条件下,重铸、引导+重铸两类修正性反馈在英语松紧元音对/i/-/I/的产出中的效用显著高于引导类修正性反馈。

The present study examined the impacts of corrective feedbacks on the perception and production of English tense-lax vowel contrast/i/-/I/.100 non-English major freshmen were randomly assigned to one of three experimental groups(recast,elicitation or elicitation+recast)or a control group.The present study employed a pre-test,6 perception-based treatment interactional activities,an immediate post-test and a delayed post-test.The participants’speech performance was measured by perception,controlled and spontaneous tests.The results show that:1)as for both the trained and untrained items,recasts,elicitations and elicitations+recasts all had beneficial effects on the Chinese EFL learners’perception of English target vowel contrast in the/i/-/I/,and there was no significant difference among the corrective feedback types,2)as for both the trained and untrained items,recasts and elicitations+recasts demonstrated significantly superior effects than elicitations on the Chinese EFL learners’production of English target vowel contrast/i/-/I/.
