Effectiveness of implicit negative feedback in a foreign language classroom: The role of input, frequency and saliency

This paper reports on a study that investigated the effectiveness of recasts and clarification requests in a French as a foreign language classroom. The target structures were French past tense structures the passé composé and the imparfait. The study was carried out with three intact classes of high school students in New Zealand, comprising in total 52 participants. A quasi-experimental design was employed, with a pre-test, treatment, immediate post-test and a delayed post-test. The treatment tasks were picture-based, designed to encourage communication and to elicit the use of past tense. The tests were also picture-based, written narrative tasks. The control group did not receive any treatment. Mixed design Repeated measures ANOVAs, followed by ANCOVAs, were computed to examine the effects of the treatment. Overall, results indicate that recasts were more effective for acquisition of the passé composé whereas both recasts and clarification requests proved beneficial for acquisition of the imparfait at this early stage of learning. However, non-parametric tests comparing more advanced and less advanced learners suggest that only the ‘low proficiency’ learners benefited from clarification requests.
