This study investigated whether different types of corrective feedback (CF) in second language speech perception training have differential effects on second language speech production. One hundred Korean learners of English were assigned to five different groups and participated in eight computer-assisted perception training sessions focusing on English vowels. While no CF was provided to the control group, participants in the four treatment groups received one of three types of auditory CF or a visual type of CF. A pretest, an immediate posttest, and a delayed posttest each consisted of a production measurement at a controlled-speech level. Results revealed that the extent to which the participants’ production accuracy benefited from the perception training depended on CF type. In addition, by adopting the perception accuracy data by Lee and Lyster (2016b), the current study found that improvement in perception accuracy was a significant predictor of improvement in production accuracy.

To what extent do second language (L2) learners benefit from instruction that includes corrective feedback (CF) on L2 speech perception? This article addresses this question by reporting the results of a classroom-based experimental study conducted with 32 young adult Korean learners of English. An instruction-only group and an instruction + CF group were exposed to five 1-hr form-focused lessons that drew learners’ attention to the nonnative phonemic contrast /i/-/ɪ/, but only the instruction + CF group was given relevant feedback. Forced-choice identification tasks were completed by participants in a pretest, an immediate posttest, and a delayed posttest. The two groups showed similar accuracy on the pretest; however, the instruction + CF group outperformed the instruction-only group on the immediate and delayed posttests as well as on unfamiliar words. The significant predictors for these differences turned out to be perceptual accuracy vis-à-vis /ɪ/-natural and /ɪ/-synthesized sounds. These findings are discussed in terms of the pivotal role played by CF in developing accuracy in L2 speech perception.

Goo and Mackey (this issue) outline several apparent design flaws in studies that have compared the impact of different types of corrective feedback (CF). Furthermore, they argue that SLA researchers should stop comparing recasts to other types of CF because they are inherently different kinds of phenomena. Our response to their article addresses (a) the claim that the recast-learning relationship has been “settled,” (b) the misleading representation of our views on uptake, (c) the characterization of the CF comparison studies as being weak and invalid, and (d) Goo and Mackey’s recommendations concerning the most appropriate approach to investigating the effect of feedback on second language learning.

This article reviews research on oral corrective feedback (CF) in second language (L2) classrooms. Various types of oral CF are first identified, and the results of research revealing CF frequency across instructional contexts are presented. Research on CF preferences is then reviewed, revealing a tendency for learners to prefer receiving CF more than teachers feel they should provide it. Next, theoretical perspectives in support of CF are presented and some contentious issues addressed related to the role of learner uptake, the role of instruction, and the overall purpose of CF: to initiate the acquisition of new knowledge or to consolidate already acquired knowledge. A brief review of laboratory studies assessing the effects of recasts is then presented before we focus on classroom studies assessing the effects of different types of CF. Many variables mediate CF effectiveness: of these, we discuss linguistic targets and learners' age in terms of both previous and prospective research. Finally, CF provided by learners and the potential benefits of strategy training for strengthening the role of CF during peer interaction are highlighted.

This quasi-experimental study is aimed at (a) teaching learners how to provide corrective feedback (CF) during peer interaction and (b) assessing the effects of peer interaction and CF on second language (L2) development. Four university-level English classes in Japan participated (N = 167), each assigned to one of four treatment conditions. Of the two CF groups, one was taught to provide prompts and the other to provide recasts. A third group participated in only peer-interaction activities, and a fourth served as the control group. After one semester of intervention, the two CF groups improved in both overall accuracy and fluency, measured as unpruned and pruned speech rates, whereas the peer-interaction-only group outperformed the control group only on fluency measures. This study draws on monitoring in speech-production theory and the declarative-procedural model of skill-acquisition theory to interpret these results, thus contributing a new theoretical approach to CF research in the context of peer interaction in which learners can be providers of CF. It is concluded that whereas peer interaction offered opportunities for repeated production practice, facilitating proceduralization, CF sharpened learners’ ability to monitor both their own language production and that of their interlocutors.

Conducted in English-as-a-foreign-language (EFL) classrooms at the university level in China, this quasi-experimental study compared the effects of three different corrective feedback treatments on 72 Chinese learners’ use of regular and irregular English past tense. Three classes were randomly assigned to a prompt group, a recast group, or a control group and then participated in form-focused production activities that elicited the target forms. In the two feedback groups, teachers consistently provided one type of feedback (i.e., either recasts or prompts) in response to learners’ errors during the activities, whereas in the control group, the teacher provided feedback only on content. Pretests, immediate posttests, and delayed posttests administered 2 weeks after the treatment assessed participants’ acquisition of regular and irregular past tense forms in both oral and written production. Comparisons of group means across testing sessions using a repeated-measures ANOVA consistently revealed large effects for time. Post hoc within-group analyses of the eight immediate- and delayed-posttest measures revealed significant gains by the prompt group on all eight measures, the recast group on four, and the control group on three. The effects of prompts were larger than those of recasts for increasing accuracy in the use of regular past tense forms, whereas prompts and recasts had similar effects on improving accuracy in the use of irregular past tense forms.

To investigate the pedagogical effectiveness of oral corrective feedback (CF) on target language development, we conducted a meta-analysis that focused exclusively on 15 classroom-based studies (N = 827). The analysis was designed to investigate whether CF was effective in classroom settings and, if so, whether its effectiveness varied according to (a) types of CF, (b) types and timing of outcome measures, (c) instructional setting (second vs. foreign language classroom), (d) treatment length, and (e) learners’ age. Results revealed that CF had significant and durable effects on target language development. The effects were larger for prompts than recasts and most apparent in measures that elicit free constructed responses. Whereas instructional setting was not identified as a contributing factor to CF effectiveness, effects of long treatments were larger than those of short-to-medium treatments but not distinguishable from those of brief treatments. A simple regression analysis revealed effects for age, with younger learners benefiting from CF more than older learners.

This comparative analysis of teacher-student interaction in two different instructional settings at the elementary-school level (18.3 hr in French immersion and 14.8 hr Japanese immersion) investigates the immediate effects of explicit correction, recasts, and prompts on learner uptake and repair. The results clearly show a predominant provision of recasts over prompts and explicit correction, regardless of instructional setting, but distinctively varied student uptake and repair patterns in relation to feedback type, with the largest proportion of repair resulting from prompts in French immersion and from recasts in Japanese immersion. Based on these findings and supported by an analysis of each instructional setting's overall communicative orientation, we introduce the counterbalance hypothesis, which states that instructional activities and interactional feedback that act as a counterbalance to a classroom's predominant communicative orientation are likely to prove more effective than instructional activities and interactional feedback that are congruent with its predominant communicative orientation.This research was supported by Standard Research Grants (410-98-0175 and 410-2002-0988) awarded to the first author from the Social Sciences and Humanities Research Council of Canada and by a Nihon University Individual Research Grant for 2005 awarded to the second author.

This article presents a corpus analysis designed to determine the extent to which noun endings in French are reliable predictors of grammatical gender. A corpus of 9,961 nouns appearing in Le Robert Junior Illustré was analysed according to noun endings, which were operationalised as orthographic representations of rhymes, which consist of either a vowel sound (i.e., a nucleus) in the case of vocalic endings or a vowel-plus-consonant blend (i.e., a nucleus and a coda) in the case of consonantal endings. The analysis classified noun endings as reliably masculine, reliably feminine, or ambiguous, by considering as reliable predictors of grammatical gender any noun ending that predicts the gender of least 90 per cent of all nouns in the corpus with that ending. Results reveal that 81 per cent of all feminine nouns and 80 per cent of all masculine nouns in the corpus are rule governed, having endings that systematically predict their gender. These findings, at odds with traditional grammars, are discussed in terms of their pedagogical implications.

This article presents a comparative analysis of five quasi-experimental studies involving close to 1,200 students, ranging in age from 7 to 14, in 49 French immersion classrooms in Canada – a content-based instructional context where learners develop high levels of communicative ability yet demonstrate a levelling-off effect in their grammatical development. The studies investigated the effects of form-focused instruction on four areas known to be difficult for anglophone learners of French: perfect vs. imperfect past tense, conditional mood, second-person pronouns and grammatical gender. Findings suggest that effective form-focused instruction in immersion contexts, at least with respect to interlanguage features that have reached a developmental plateau, includes a balanced distribution of opportunities for noticing, language awareness and controlled practice with feedback. Less effective instructional options overemphasise negotiation for meaning in oral tasks where message comprehensibility and communication strategies circumvent the need for learners to move beyond the use of interlanguage forms.

Four teachers and their eight classes of 179 fifth-grade (10–11-year-old) students participated in this quasi-experimental classroom study, which investigated the effects of form-focused instruction (FFI) and corrective feedback on immersion students' ability to accurately assign grammatical gender in French. The FFI treatment, designed to draw attention to selected noun endings that reliably predict grammatical gender and to provide opportunities for practice in associating these endings with gender attribution, was implemented in the context of regular subject-matter instruction by three of the four teachers, each with two classes, for approximately 9 hours during a 5-week period, while the fourth teacher taught the same subject matter without FFI to two comparison classes. Additionally, each of the three FFI teachers implemented a different feedback treatment: recasts, prompts, or no feedback. Analyses of pretest, immediate-posttest, and delayed-posttest results showed a significant increase in the ability of students exposed to FFI to correctly assign grammatical gender. Results of the written tasks in particular, and to a lesser degree the oral tasks, revealed that FFI is more effective when combined with prompts than with recasts or no feedback, as a means of enabling L2 learners to acquire rule-based representations of grammatical gender and to proceduralize their knowledge of these emerging forms.This study was funded by the Social Sciences and Humanities Research Council of Canada (nos. 410-98-0175 and 410-2002-0988).

This study examines aspects of communicative classroom discourse that may affect the potential of recasts to be noticed as negative evidence by young second language learners. The database comprises transcripts of over 18 hours of interaction recorded during 27 lessons in 4 immersion classrooms at the primary level. The 377 recasts in the database have been classified according to their pragmatic functions in classroom discourse and then compared to the teachers' even more frequent use of noncorrective repetition. Findings reveal that recasts and noncorrective repetition fulfill identical functions distributed in equal proportions and, furthermore, that teachers frequently use positive feedback to express approval of the content of learners' messages, irrespective of well-formedness, to accompany, also in equal proportions, recasts, noncorrective repetition, and even topic-continuation moves following errors. The findings suggest that, from the perspective of both learners and teachers, the corrective reformulations entailed in recasts may easily be overridden by their functional properties in meaning-oriented classrooms.

This article presents a study of corrective feedback and learner uptake (i.e., responses to feedback) in four immersion classrooms at the primary level. Transcripts totaling 18.3 hours of classroom interaction taken from 14 subject-matter lessons and 13 French language arts lessons were analyzed using a model developed for the study and comprising the various moves in an error treatment sequence. Results include the frequency and distribution of the six different feedback types used by the four teachers, in addition to the frequency and distribution of different types of learner uptake following each feedback type. The findings indicate an overwhelming tendency for teachers to use recasts in spite of the latter's ineffectiveness at eliciting student-generated repair. Four other feedback types—elicitation, metalinguistic feedback, clarification requests, and repetition—lead to student-generated repair more successfully and are thus able to initiate what the authors characterize as the negotiation of form.
