corrective feedback

Various studies have confirmed the influential role of corrective feedback (CF) in the development of different linguistic skills and components. However, little, if any, research has been conducted on comparing types of linguistic errors treated by teachers through CF. To bridge this gap, this study sought to investigate the linguistic errors addressed and the types of CF provided by teachers. To this end, the classes of 40 teachers teaching at the intermediate level were audio-recorded for two successive sessions. The detailed analysis of around 128 hours of classroom interactions showed that explicit correction was the most frequent CF type, accounting for 48.5 percent of all CF types provided, and recast was the second most frequently used CF type, constituting 29.5 percent of all CF types. All the other CF types (i.e. request for clarification, confirmation check, repetition, metalinguistic feedback, elicitation, and multiple feedback) constituted 22 percent of the CF. Repetition was the least frequently used CF type, amounting to 0.66 percent of the CF given by teachers. As to the linguistic focus of CF, pronunciation errors were found to be the mostly noticed target for teachers’ CF, constituting 47 percent of all errors addressed, while vocabulary was the least frequently addressed linguistic target, accounting for 17.5 percent of all errors. The study suggests that teachers prefer explicit corrective strategies over implicit ones and that they provide CF mainly to correct pronunciations errors. The study suggests that there is a need for change in the types of CF teachers use and the relative attention they assign to different linguistic error types they treat through CF

Over the last few years, the realm of foreign language learning has witnessed an abundance of research concerning the effectiveness of corrective feedback on the acquisition of grammatical features, with the study of other target language subsystems, such as pronunciation, being few and far between. In order to bridge this gap, the present study intended to investigate and compare the immediate and delayed effect of explicit (overt) and implicit (covert) corrective feedback (CF) on treating segmental word-level pronunciation errors committed by adult EFL learners of an institute in Tabriz named ALC. To this end, through a quasi-experimental study and random sampling, three groups were formed, an explicit, an implicit and a control group, each consisting of 20 low proficient EFL learners. Besides, considering the levels that learners were assigned to, based on the institute’s criteria, a Preliminary English Test (PET) was administered in order to determine the proficiency level of learners. Having administered the pretest before treatment, to measure the longer-term effect of explicit vs. implicit CF on segmental word-level pronunciation errors, the study included delayed posttests in addition to immediate posttests all of which included reading passages containing 40 problematic words. The collected data were analyzed by ANCOVA and the obtained findings revealed that both explicit and implicit corrective feedback are effective in reducing pronunciation errors showing significant differences between experimental and control groups. Additionally, the outcomes showed that immediate implicit and immediate explicit corrective feedback have similar effects on reduction of pronunciation errors. The same result comes up regarding the delayed effect of explicit feedback in comparison with delayed effect of implicit feedback. However, the delayed effect of explicit and implicit CF lowered comparing to their immediate effect due to time effect. Pedagogically, this study could enhance teachers’ effort, knowledge, and beliefs in teaching pronunciation and providing corrective feedback to pronunciation errors.   Keywords:corrective feedback; explicit CF; implicit CF; segmental word-level pronunciation errors   طی چند سال اخیر، در حوزه ی آموزش زبان انگلیسی شاهد تحقیقات کثیری در زمینه ی ﺗﺄثیر بازخورد اصلاحی بر یادگیری ساختار های دستور زبان انگلیسی بوده ایم.  با این وجود، در رابطه با ﺗﺄثیر آن در یادگیری تلفظ صحیح زبان انگلیسی تحقیقات بسیار اندکی انجام شده است. به منظور پر کردن این ﺧﻸ، مطالعه ی حاضر سعی داشته به بررسی و مقایسه ی ﺗﺄثیرات آنی و مدت دار بازخورد اصلاحی صریح و ضمنی در بهبود خطاهای تلفظی واحد های زنجیری در کلمات انگلیسی بپردازد.بدین منظور، طی یک تحقیق نیمه تجربی، شرکت کنندگان که از زبان آموزان انگلیسی به عنوان زبان خارجی انتخاب شده بودند به سه گروه صریح، ضمنی و کنترل تقسیم شدند. هر کدام از این گروه ها شامل 20 زبان آموز سطح پایین بوده که تواناییشان در تلفظ لغات مورد نظر از طریق پیش آزمون، پس آزمون فوری و پس آزمون تاخیری اندازه گیری شد.اطلاعات به دست آمده از طریق آزمون تحلیل کوواریانس ANCOVA تحلیل و بررسی شد. تفاوت معنادار بین گروههای آزمایشی و کنترل در یافته های به دست آمده نشان می دهد که هر دو بازخورد صریح و ضمنی تاثیر بسزایی در کاهش خطاهای تلفظی زبان آموزان در پس آزمون فوری داشته است. همچنین تاثیر مشابهی در پس آزمون تاخیری دو گروه صریح و ضمنی مشاهده شد. با این وجود، مقایسه ی بین پس آزمون های فوری و تاخیری نشان داد که تاثیر بازخورد در هر دو گروه آزمایشی با گذشت زمان کاهش یافته است. کلیدواژه ها: بازخورد اصلاحی، بازخورد اصلاحی صریح، بازخورد اصلاحی ضمنی، خطاهای تلفظ زنجیره ای

Despite the increasing popularity of error treatment as a research subject, the effect of age as a potential learner-internal factor affecting choice of feedback is largely undertreated. Characterized by being at early stages of self-empowerment, young language learners are considerably vulnerable and in need of particular language input to meet their age-appropriate psychological demands. This study is one of the early attempts to detect the appropriate corrective feedback for children’s linguistic (grammar uptake) and personality (willingness to communicate) development. Thirty-seven young language learners ( mean age = 10.32) at two pre-intermediate classes in a non-profit language institute took part in this study. Following intact group design, they were divided into two groups of recasts and explicit feedback. Whereas in the recast group, all or part of an erroneous utterance was reformulated by teacher, correct forms were directly and explicitly provided in the explicit group in the course of a semester ( 19 sessions ´ 50 min=950 mins). A structured willingness to communicate (WTC) scale and two parallel grammaticality judgment tests were administered at pre- and post-intervention conditions; this stage was accompanied by the teacher’s formative observations using an unstructured WTC checklist and a tally chart worksheet. The results of the quantitative phase revealed higher grammar uptake for the recast group. Besides, students in the implicit group showed more WTC in both quantitative and qualitative investigations. These findings indicate that for young learners the use of a less direct way might be more effective in both raising their unconscious L2 knowledge and willingness to participate in classroom activities.

The present study investigated differential effect of two types of feedback namely, computer-mediated and metalinguistic, on Iranian EFL learners’ writing accuracy. To this end, based on Nelson Proficiency Test (300 A), 69 Iranian advanced EFL learners, including 45 males and 24 females, aged between 17 and 24, learning English in language institutes in Salmas, were selected randomly out of the total population of 121 EFL learners and then divided into three groups. The participants in the two experimental groups received metalinguistic and computer-mediated feedback separately while those in the control group received no feedback. The analyses of the results obtained through a pre-test and a post-test indicated that both feedback types significantly influenced learners’ writing accuracy. However, analysis of the participants’ performances on the post-test demonstrated that metalinguistic group outperformed computer-mediated one. Thus, the effect of metalinguistic feedback was more than that of computer-mediated feedback. In addition, both of them were more influential than no-feedback instruction. The findings of the present study can be fruitful for syllabus designers and EFL teachers. 

The role of oral corrective feedback has been investigated by SLA researchers from various perspectives. Focusing on Iranian EFL context, the present study aimed to explore the role of receiving corrective feedback in the learning of English grammatical structures. It also probed the association between the type of corrective feedback and EFL learners’ learning styles. This was an experimental study examining a sample of 128 intermediate-level EFL learners through pretest-posttest control group design. Data of the study was analysed through one-way ANOVA conducted on post-test scores. Results of the study indicated that there were statistically significant differences between experimental groups and control group in terms of receiving feedback. These findings implied the outperformance of the metalinguistic feedback group over recast group and also the superiority of providing EFL learners with feedback compared to no-feedback. The results obtained from two-way ANOVA revealed an effectively significant interaction between the type of oral corrective feedback and the learners’ learning styles. The study discussed how both types of corrective feedback and learning styles could manipulate L2 acquisition which might have some implications for EFL language teachers in the classroom.

It is often wrongly assumed that the provision of teacher corrective feedback naturally entails learners' attendance to and application of it, but learners have repeatedly been reported not to pay attention to teacher feedback due to lack of motivation and the distracting effect of the grades they receive. The present study was an attempt to tackle this problem. To do so, the technique named Draft-Specific Scoring (Nemati & Azizi, 2013) was implemented. In DSS, learners receive both teacher feedback and grades on their first drafts; however, they are given up to two opportunities to apply teacher feedback and revise their drafts accordingly. The scores they receive may improve as a result of the quality of revisions they make. Students’ final scores will be the mean score of the grades they receive on the final drafts of each assignment. 57 Iranian intermediate students attending the ‘Advanced Writing’ course at University of Teheran, with an age range of 21 to 27 took part in this study. The gain score analysis and the SPANOVA used showed the superiority of DSS over more traditional methods in improving learners’ overall writing proficiency as well as fluency and accuracy of their written texts. Moreover, no adverse effect was observed for the treatment group regarding the grammatical complexity of their texts. This indicates that in order to make teacher feedback work, there are a number of intervening variables one needs to consider, the most important of which being learners’ motivation to attend to teacher feedback.

One of the important issues in EFL instruction is the idea of eliminating students’ linguistic errors through providing corrective feedback (CF). Accordingly, this study investigated the effect of various CF types (i.e., comprehensive, selective, and no feedback) on advanced EFL learners’ writing in different writing conditions (i.e., individual & collaborative). 132 EFL advanced learners aged from 14-20 were considered as the main participants. Learners were divided into 6 groups (i.e., three individual and three collaborative writing conditions). Furthermore, each writing condition included three groups with selective, comprehensive, and no correction orientations. Data collection tools and procedures encompassed an institutionalized Placement Test, pre-test, and post-test. The treatment that lasted for nine sessions was followed by a post-test. Data were submitted to a series of ANOVA tests with follow up pair-wise comparisons and independent-samples t-tests. Findings indicated that: (1) CF, especially selective one, was more effective in enhancing learners’ writing accuracy, and (2) members of the collaborative writing groups outperformed those in the individual ones in terms of their writing accuracy development. The theoretical and practical implications are discussed in relation to enhancing writing accuracy of the learners.

Based on the controversial beliefs among L2 teachers about effective corrective feedback (CF) strategies, recast and prompts as 2 kinds of CF have drawn the attention of L2 researchers(e.g., Braidi, 2002; Iwashita, 2003; Loewen & Philp, 2006; Panova & Lyster, 2002; Sheen, 2004). Despite these numbers of studies, debate continues to exist about their usefulness as a CF technique. Whereas recasts provide a correct reformulation of L2 learners’ nontarget utterance, the other alternative type of feedback in L2 classroom settings is referred to as prompts (Lyster, 2004) because they provide signals that prompt L2 learners to self-repair rather than provide them with a correct reformulation of their nontarget utterance. Hence, the focus of this study was to examine the effect of recasts in comparison to prompts on the learning of English third person singular marker “s” by Iranian preintermediate L2 learners. Two CF techniques of recasts and prompts were utilized in 2 experimental groups in response to their errors in using the correct form of the verb for third person singular subject. In the third group as the control group, No-CF was provided by the L2 teacher. The results revealed that the Prompts Group had outperformed the Recast Group and No-CF Group. Thus, it could be concluded that prompts as a CF strategy led to more gains than CF that provided the L2 learners with the correct form (recast) than No-CF.  

This study investigates the effect of four types of oral corrective feedback, namely, explicit elicitation, implicit elicitation, explicit recast and implicit recast on the most commonly mispronounced phonological features among Iranian EFL learners through immediate uptake and retention. Five classes were randomly categorized into four experimental groups and one control group, each with 18 intermediate-level male learners. The treatment was conducted in the form of a retelling task in nine sessions. During the feedback sessions, the learners’ uptake was recorded. The learners’ retention was also perused in one immediate and one delayed post-test. The results revealed that those learners who received explicit recast obtained the highest score in terms of correct uptake, and that the groups performed differently across different time periods. The learners’ scores enhanced over time; however, the increase then leveled off and even dropped in the delayed post-test in all the experimental groups except for the group which received explicit elicitation, apparently leading to more retention of the target phonological features. The study offers insights to teachers regarding the effect of recast and elicitation in their explicit and implicit form on L2 pronunciation.

This study investigated the effects of corrective feedback (CF) on the acquisition of English prepositions to find out which one would be more effective for third-grade high school learners in their grammar performance. This study also examined declarative and interrogative recasts to see which one the participants preferred to improve their grammar performance. To this end,75 out of 130 female students at the intermediate level in Khorramshar took part in this study. The participants were randomly assigned into one control and two experimental groups. All three groups took the same pre and posttests; however, the treatment was different. The recast group received CF in the form of recast and the other in the form of metalinguistic clues. The control group only received general comments, like good, bad, etc. The results indicated that both experimental groups improved in preposition recognition and production in their grammar performances. The findings also showed that there was no significant difference between the students'' performance in experimental groups, but metalinguistic CF was more helpful. A careful calculation using a questionnaire based on 5-points Likert Scale showed that there was no significant difference between the participants'' preference for two types of recast by the group receiving recasts.

This study investigated the effects of prompts as corrective feedback strategy on teaching /θ/ and /ð/ sounds to Iranian EFL learners. To achieve this objective, after 30 students studying English at a language institute took a placement test, the intermediate-level students were selected based on their scores on this test. They were randomly assigned to one experimental group and one control group. The experimental group was instructed these two sounds giving prompts as corrective feedback, while the control group received no feedback. In this experimental study, two teacher-made tests on sounds /θ/ and /ð/ were administered to the participants before and after the treatment. After collecting the data and confirming normality of them; through employing two independent-samples t tests and two paired-samples t tests, the collected data were analyzed. The results indicated that language learners in the experimental group did not significantly outperform in the posttest; thus, it can be concluded that prompts were not an effective feedback in teaching these two sounds to Iranian intermediate EFL learners. Findings of the present study can help language teachers and teacher trainers in teaching these complex sounds to Iranian EFL learners

This paper aimed at examining the Iranian EFL teachers and learners’ preferences for two types of direct oral corrective feedback, including explicit correction and metalinguistic clues, and two types of indirect oral corrective feedback, including recast and repetition. The participants included 39 teachers and 84 EFL learners, selected through purposive sampling. A scenario-based questionnaire was constructed based on Lyster and Ranta’s (1997) typology of corrective feedback (CF) for the purpose of collecting data on the teachers and learners’ preferences for the type of CF. Feedback scenarios were extracted from the literature on CF. The questionnaire was distributed to the participants by one of the researchers. Semi-structured interviews were also conducted in order to triangulate the data gathered through the questionnaire. The results of the study indicated that the EFL teachers and learners preferred direct CF more than indirect CF. The results also revealed significant differences among EFL teachers with differing levels of teaching experience (i.e., low, moderate and high). The present study drew attention to the fact that direct types of CF were preferred over others in EFL context. This study has implications for EFL teachers, learners, and material developers.

: Corrective Feedback (CF) provision on performance involves calling attention to learners' erroneous utterances, which stimulates classroom language learning. Despite widespread research in this area, a controversy still exists as to the time of CF in communicative tasks especially when learners' task engagement is targeted. Employing 60 intermediate-level Iranian learners, a four-week study examined the effects of immediate versus delayed CF types on oral engagement, grammar gain as well as on Complexity, Accuracy and Fluency (CAF) in the context of a dictogloss task. The statistical analysis showed that despite statistically significant improvements in the case of Grammaticality Judgement Test (GJT) from the pre-test to the post-test, no statistically significant difference was found between the two groups with regard to their grammar gain, complexity, accuracy, fluency, as well as on their social and cognitive engagement. However, results in the case of behavioral and emotional engagement revealed that there were statistically significant differences between the two groups of immediate and delayed CFs. The findings of the present study call for more flexibility and confidence on the part of the teachers in providing either immediate or delayed CF whenever appropriate and without being concerned about the adverse effects of feedback

Giving corrective feedback (CF) is an essential part of the teaching and learning process, and the way it should beneficially be done has been the focus of attention for numerous researchers especially when traditional ways of CF provision are not possible, particularly in rare situations such as outbreaks of diseases. This study investigated how different ways of giving feedback; namely, through online chats and class discussions can help language learners in benefitting from their instructors’ CF provision. To this purpose, the effects of two ways of feedback provision were tested on the participants writing quality. Three hundred and seventeen Iranian EFL learners took a TOEFL test, 132 of them (53 males and 79 females) scoring between 477 and 510 were asked to deliver a 200-word writing task. Then, they were randomly put into 4 experimental and control groups to undergo different treatments, i.e. receiving CF through online chats and class discussions for 10 one-hour sessions. After the treatment, they were required to deliver another 200-word piece of writing. The results of statistical data analysis showed that the writing quality of the participants receiving CF through online chats was significantly higher than that of those who received CF through class discussions. The findings of this research have practical implications for Iranian educational system to update its instructional methods and for the nature of teaching and learning processes and practices.

همچنان عدم قطعیت های زیادی در خصوص نقش محتمل عوامل میانجی فراوان نظیر زمینه زبانی و قومیت در فرایند بازخود اصلاحی وجود دارد. در پاسخ به این موضوع، مطالعه حاضر بر روی 79 زبان آموز فارس و 79 زبان آموز دوزبانه ترکمن با سن 13 تا 18 سال در دو موسسه آموزش زبان استان گلستان صورت گرفت. شرکت کنندگان به سه گروه تیمار و یک گروه کنترل تقسیم شدند. دو پیش آزمون، اشتباهات گرامری زبان آموزان را نشان داد که براساس آن سه راهبرد بازخورد اصلاحی فرازبانی شفاهی، کتبی و تلفیقی تنظیم گردید و بر روی 5 اشتباه گرامری پرتکرار زبان آموزان اعمال شد. گروه کنترل تیماری دریافت نکرد. آزمون کروسکال والیس نشان دهنده تفاوت معنی دار گروه ها پیش و پس از تیمار بود که براساس آن، پس-آزمون مقایسه زوجی کانوور انجام شد. نتایج نشان داد که در فارس ها و ترکمن ها تیمارها به شکل معنی داری بر روی کاهش اشتباهات گرامری اثر گذاشته است. راهبردهای اصلاحی فرازبانی شفاهی و تلفیقی برای فارس ها و هر سه راهبرد برای ترکمن ها بر روی کاهش اشتباهات اثر معنی دار داشتند. رتبه راهبردها به کمک روش نزدیکی به راه حل ایده آل (تاپسیس) با وزن برابر اشتباهات بررسی شد که برای فارس ها، روش شفاهی و برای ترکمن ها روش کتبی را به عنوان بهترین نشان داد. روش تاپسیس با تغییر وزن ها به میزان 50 درصد به میزان 10000 بار تکرار شد که نشان دهنده ثبات رتبه بندی به دست آمده بود. نتایج این پژوهش می تواند برای فراگیران زبان انگلیسی به عنوان زبان خارجی، آموزگاران زبان به فراگیران دوزبانه، طراحان سرفصل دروس و مواد آموزشی کمک نماید و هم زمان درهای جدیدی به سوی پژوهش های مرتبط بگشاید.

Corrective feedback refers to a teacher or student’s reaction to a learner’s target language production containing an actual or perceived error. The last three decades have witnessed a large amount of research on the impacts of various types of corrective feedback on students’ written production. Along the same vein, the present study seeks to explore the effectiveness of providing teachers’ metalinguistic feedback vs. peers’ collaborative feedback on students’ writing performance. In so doing, the present study adopted a pretest-posttest quasi-experimental design including three upper-intermediate groups (i.e., two experimental and one control). The participants of the study were a total of 62 English as a foreign language (EFL) freshman students from two public universities in Tehran, Iran. The writing tasks utilized in the present study were adopted from IELTS writing Task 2. The results of one-way between groups analysis of variance (ANOVA) revealed that students produced significantly more lexically diverse as well as grammatically accurate language as a result of both treatments. Moreover, it was observed that collaborative peer feedback led to significantly higher lexical diversity than those of other two groups. The findings of the present study suggest that L2 teachers can opt for a combination of corrective feedback strategies to help learners improve their writing performance.

This study investigated the effects of recast and explicit corrective feedback on Iranian IELTS test-takers anxiety in speaking across different levels of proficiency. Ninety male and female learners, aged 21 to 45, who were preparing themselves to take the IELTS Mock test, were divided into upper-intermediate and advanced levels. Then, they were randomly assigned to control and experimental groups (recast and explicit correction). There were 10 treatment sessions for each group. In the recast group, the students’ mistakes were corrected using reformulation. In the explicit correction group, mistakes were not tolerated, and they were corrected on the spot. In order to measure the anxiety in speaking performance, Chowdhury’s (2014) questionnaire was given to the participants once before the treatment and once after the treatment. Then, the score of each learner was calculated and recorded for the data analysis. The results showed that there was no statistically significant difference between the control and explicit corrective group and the control and recast groups at the upper-intermediate level. However, there was a statistically significant difference between the control and recast groups and the control and explicit group at the advanced levels.

This study attempted to determine the viability of the pedagogic interventions in ESP writing courses that fall within the ambit of Written Corrective Feedback (WCF). Considering this objective, 93 intermediate-level ESP learners in 3 intact classrooms of a medical sciences university in Iran were assigned to three groups. They were provided with corrective feedback; using three feedback strategies comprising direct, indirect, and metalinguistic WCF over ten treatment sessions. The researchers endeavored to itemize the utility of the interventions mentioned above via analyzing the participants’ performance on an immediate and a delayed writing posttest. The results displayed the efficacy of WCF for the betterment of the ESP learners’ writing performance. Furthermore, they accentuated the short-term and long-term supremacy of explicit WCF strategies (i.e., metalinguistic & direct) over the implicit ones (i.e., indirect). The findings might enable syllabus designers and curriculum developers to redress the English courses for students of allied medical sciences.
