ABSTRACTThis 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.

Speech Perception And Production

ABSTRACTThe current study examines in depth how two types of form-focused instruction (FFI), which are FFI with and without corrective feedback (CF), can facilitate second language speech perception and production of /ɹ/ by 49 Japanese learners in English as a Foreign Langage settings. FFI effectiveness was assessed via three outcome measures (perception, controlled production, and spontaneous production) and also according to two lexical contexts (trained and untrained items). Two experimental groups received 4 hr of FFI treatment to notice and practice the target feature of /ɹ/ (but without any explicit instruction) in meaningful discourse. A control group (n = 14) received comparable instruction in the absence of FFI. During FFI, the instructors provided CF only to students in the FFI + CF group (n = 18) by recasting their mispronunciations of /ɹ/, while no CF was provided to those in the FFI-only group (n = 17). Analyses of pre- and posttests showed that FFI itself can sufficiently promote the development of speech perception and production of /ɹ/ and the acquisitional value of CF in second language speech learning remains unclear. The results suggest that the beginner learners without much phonetic knowledge on how to repair their mispronunciation of /ɹ/ should be encouraged to learn the target sound only through FFI in a receptive mode without much pressure for modified output.

Facilitative Role

AbstractThe role of written corrective feedback (CF) in the process of acquiring a second language (L2) has been an issue of considerable controversies over past decades. This study thus endeavors to extend current work on written CF by investigating and comparing the effect on collocation learning of one traditional type of feedback—direct corrective feedback (DCF)—with an innovative type of error correction, feedback provided within context—situated feedback (SF). The effects of the two types of written feedback were measured by examining the accurate use of target collocations in a translation test and a multiple choice test completed by 73 intermediate EFL students in China. Three groups were formed: a DCF group, an SF group, and a control group. The study found that both treatment groups outperformed the control group in the posttests and delayed posttests and that there were significant advantages of the SF group in comparison to the DCF group in both posttests. The results suggested that the provision of written CF was helpful for collocation learning and that situational context could promote the facilitative role of written CF in language acquisition. These findings are discussed from the perspectives of both second language acquisition (SLA) theory and language pedagogy and implications for future research efforts are put forward.

Abstract Background Cryopreservation of stallion spermatozoa tends to cause plasma membrane damage due to the low ratio of cholesterol to phospholipids. Gums have been suggested as an alternative cryoprotectant to glycerol for stallion spermatozoa. Therefore, the present experiment was designed to verify whether the effect of addition of cashew gum (CG), or nanoparticles (NP) containing CG, to the extender before cooling on sperm quality in stallion semen. Ejaculates from 6 stallions were extended and split between six treatment groups (control, a-tocopherol [TOC], CG1, CG0.5, NP1 and NP0.5), stored in cryotubes at 4 °C. Results Aliquots were analysed by computer-assisted sperm motility analysis on the day of collection, and after 24 h and 48 h of cold storage. After 48 h, the total motility with NP1 (78.53 + 6.31%) was similar to control 85.79 + 6.31% at 0 h. The same pattern was observed for progressive motility. Membrane integrity assessed by flow cytometer was similar between control, TOC and G1 at all storage times. The DNA fragmentation in the control group increased at all time points, whereas chromatin integrity was maintained after 24 h in TOC and NP0.5 compared to 0 h. There was no increase in the proportion of live spermatozoa producing hydrogen peroxide, but there was a tendency for an increased proportion of spermatozoa in the live superoxide category in CG1 after 24 h cooled storage. Conclusions The addition of CG or CG-derived NP to extender for stallion semen was not harmful to the sperm cells.

This study investigated a computer-assisted pronunciation training (CAPT) software that utilized automatic speech recognition (ASR) and accent conversion technology to improve pronunciation of second language learners. Such speech processing method is capable of addressing the typical shortcoming of ASR technology for L2 pronunciation training, which is providing meaningful corrective feedback. Thirty-six student participants were involved in the treatment group. For the treatment, they worked on a CAPT tool that utilized ASR and AC to provide the participants with corrective feedback. A comparison group was also used and consisted of 36 students but worked on a different type of CAPT tool. Two trained raters took part in rating each monologue completed for the pretest, posttest, and comparison data. Findings showed preliminary statistical significance in regards to improved pronunciation for the treatment group. Additional results also showed no statistical differences in the rater scores between the control group and the experimental posttest scores.

This study investigated the effects of comprehension-directed and memory-directed computer-based learning-strategy training on the achievement of learning objectives. The subjects were sixty undergraduate students enrolled in an introductory computing course. Learners completed a tutorial about microcomputer components on the first day of the study. Two treatment groups completed a strategy-training tutorial focusing on comprehension or memory. The control group received extra time on the microcomputer-components tutorial and no strategy training. One week later, all subjects completed two separately administered tests including cued recall and recognition. The strategy training effects were significant on the fifty-item cued recall test, however, group mean scores were at or below 50 percent. Group mean scores on a recognition text suggested that comprehension-directed training was the most effective. All treatment group mean scores were significantly higher than the control group. The findings of this study provide a basis for further research into the design of computer-based learning-strategy training and assessment.

This study aims to examine the impact of formative assessment with corrective feedback as one of the effective tools that improve the performance of students who study English as a second language (L2 learners). More specifically, it contributes to research on the complex relationship between the attitudes and practices of English language teachers and students regarding the way they understand and practice the basics of formative assessment and corrective feedback when checking students’ achievement. In order to achieve this goal, the study investigated this matter in light of the following guiding questions: What are the effects of corrective and formative feedback in improving students who are learning English as a second language level L2 learners? How might teachers provide effective assistance to their students during this stage?To address these questions, A total of 58 subjects were divided into a control group (n=29) and an experimental group (n=29). All the subjects were second-year cadets at a military academy. Both groups were given a pre-test prior to the teaching of English “comparative forms”. The purpose of the pre-test was to make sure that the two groups were homogenous. The pre-test was then followed by the teaching of English “comparative forms” in both groups. The experimental group was given a formative assessment where each subject also received one-on-one corrective feedback. Finally, a post-test (summative assessment) was given to both groups.After collecting and analyzing the data, it was found that providing a formative assessment and corrective feedback has a positive impact on improving students’ level of accurate understanding accurately and student writing as well as correct reading.

Direct Feedback

Most second language researchers agree that there is a role for corrective feedback in second language writing classes. However, many unanswered questions remain concerning the linguistic features to target and the type and amount of feedback to offer. This study examined essays by 151 learners of English as a second language (ESL), in order to investigate the effect of either direct or metalinguistic written feedback on errors with the simple past tense and the present perfect tense. This inquiry also considered the extent to which learner differences in language-analytic ability (LAA), as measured by the LLAMA F, mediated the effects of these two types of explicit written corrective feedback. Learners in both feedback groups were provided with corrective feedback on two essays whereas the control group received general comments on content. Learners in all three groups then completed two additional writing tasks to determine whether or not the provision of corrective feedback led to greater gains in accuracy compared to no feedback. Both treatment groups performed better than the comparison group on new pieces of writing immediately following the treatment sessions, yet direct feedback was more durable than metalinguistic feedback for one structure, the simple past tense. Participants with greater LAA proved more likely to achieve gains in the direct feedback group than in the metalinguistic group, whereas learners with lower LAA benefited more from metalinguistic feedback.

The Impact

This study examined the effectiveness of written corrective and the role of individual differences (ID) in the uptake of the feedback. Data was taken from a nine-week, English as a foreign language (EFL) writing course from 101 intermediate (n=101) students at a private university in Kobe, Japan. Using an explanatory sequential mixed methods design, quantitative data was first collected concerning writing errors, followed by qualitative semi-structured interviews. Three classes were placed into either two treatment groups (direct and indirect) or a control group, and completed four writing tasks (pre-test, post-test and two delayed post-tests). The study found the two treatment groups showed significant improvements on local and global errors, whereas the control group did not. Additionally, the qualitative component elicited the influence of affective factors. The study adds to the body of literature addressing the impact of written corrective feedback, specifically on students’ self-editing strategies.
