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.

The study examines whether there is any difference between the effects of a reading–writing integrated task and comprehensive corrective feedback (CF) on English as a foreign language (EFL) learners’ writing development, and whether the input language in the integrated task makes a difference in L2 writing development over time and the language accuracy of the writing resulting from the integrated task. It also explores the possible relationships among language, content alignment and language accuracy and the relationship between language alignment and content alignment. To this end, a quasi-experimental study was conducted to assess participants’ L2 writing development based on a pretest–posttest–delayed-posttest design implemented in four intact EFL freshman classes. Four groups were created: an English-reading–English-writing (EE) group, a Chinese-reading–English-writing (CE) group, a comprehensive CF group, and a control group, which engaged solely in writing practice. The results demonstrated that (1) the EE and CF groups outperformed the control and CE groups on the posttest and outscored the control group on the delayed posttest with respect to language, although there were no significant differences among the three experimental groups in overall, content, and organization scores; (2) the input language of the integrated reading–writing task had a significant effect on language accuracy in the resulting essays; and (3) there was no significant correlation between content alignment and language accuracy for the CE group, whereas for the EE group, a significant positive correlation was observed not only between content and language alignment, on the one hand, and language accuracy, on the other hand, but also between content alignment and language alignment.

Grammatical Structures

The exploratory study investigated the effectiveness of a new tool referred to as the error correction log (ECL). It was designed from a cognitive SLA perspective to facilitate learning, in the context of this study, of grammatical structures, following the receipt of written corrective feedback (WCF). The uniqueness of the ECL is that it guides learners through the cognitive processes deemed to underlie acquisition of grammatical structures, namely, noticing-the-gap (Schmidt & Frota, 1986), noticing (Schmidt, 1990, 2001) and noticing with metalinguistic understanding (Leow, 1997; Schmidt, 2001), and in the process potentially change the type of WCF available to learners. As the ECL was designed by the author, no study has investigated its effectiveness against a more established means of attending to WCF. In the case of the study presented here, the ECL was compared against studying WCF for a period of time. Utilizing a quasi-experimental design (a pre-test, treatment, immediate post-test, and delayed post-test), the treatment was a focused direct WCF plus ECL group versus a focused direct WCF plus study group. A control group received no WCF. The tests were three writing tasks; the target structure was regular past tense verbs. While the ECL group improved over time, the study group and the control group did not. The ECL group outperformed the control group in the delayed post-test, whereas the study group did not. An analysis of whether the corrected past tense verbs were subsequently used or not used in the post-tests demonstrated a lack of correct use for the ECL group; this, with an analysis of the ECLs for the provision of a metalinguistic explanation, suggest learners may have been able to change direct WCF (potential noticing) to direct WCF plus metalinguistic explanation (potential noticing plus metalinguistic understanding) leading to the suggestion these learners likely drew on the corrected verbs, their preexisting vocabulary-learned knowledge and preexisting metalinguistic knowledge (implicitly and explicitly acquired) when completing the delayed post-test. These results will be discussed in relation to research, theory and practice.

Shed Light

Although there is evidence that corrective feedback (CF) is beneficial for the learning of L2 morphosyntax in instructed contexts, the effects of oral feedback for the learning of complex forms displaying opaque form-meaning relationships have remained largely unexplored. In this quasi-experimental study 44 adult L2 learners of Italian were pseudo-randomly assigned to a recast, an elicitation and a control group and compared on the accuracy in the oral production of passato prossimo, a past tense construction including auxiliaries and participles displaying morphemes with different degrees of opacity. Posttest and delayed posttest gains in the overall accuracy of the construction were significant for recasts (p < .05, d = 1) and elicitations (p < .01, 1.2 ≥ d ≥ 1.5). However, recast gains were significant for both transparent and opaque forms and their syntactic domain included both participle and auxiliary morphology, whilst elicitation gains focused on transparent forms and appeared to have a narrower syntactic focus. These results provide evidence in support of the view that recasts are beneficial for the acquisition of complex forms and indicate that more research is needed to shed light on how implicit and explicit instructional strategies are best effective depending on the transparency of the linguistic target.

This article examines whether there is any difference between the effect of oral and written corrective feedback (CF) on learners’ accurate use of English articles. To this end, the current research presents the results of a quasi-experimental study with a pretest, immediate-posttest, delayed-posttest design, using 12 intact intermediate English-as-a-second-language classes with adult learners of various first language backgrounds. Five groups were formed: oral recasts (n= 26), oral metalinguistic (n= 26), written direct correction (n= 31), written direct metalinguistic (n= 32), and control (n= 28). All four experimental groups completed two 30-min communicative narrative tasks. For the oral CF groups, students were asked to retell a story during which CF was provided. For the written CF groups, students were first asked to rewrite a story and then given CF. The acquisition of English articles was measured by means of a speeded dictation test, a written narrative test, and an error correction test. One-way ANOVAs with post hoc comparisons indicated that all CF groups, except for oral recasts, significantly outperformed the control group in the immediate and delayed posttests. These findings show that, whereas implicit oral recasts that involve article errors were not facilitative to learning, the other CF types were effective in helping learners improve the grammatical accuracy of English articles irrespective of language analytic ability. Overall, these results suggest that the degree of explicitness of both oral and written CF—rather than the medium in which the CF is provided—is the key factor that influences CF effectiveness.

Grammatical Structures

The studies on error correction have been laying their emphasis on grammatical structures of the language with lack of focus on non-grammatical aspect such as lexical collocation. Therefore, this study aims at investigating the effect of direct and indirect written corrective feedback on low-performing ESL learners. Ninety-two students of a public university involved in the study. Three intact groups that have equal proficiency were identified at the beginning of the university’s academic term. A quasi-experimental design was employed with two experimental groups receiving indirect WCF and direct WCF separately, and a control group deprived of any treatment. The groups were measured in three different time points with pre-test before the intervention, immediate post-test after the intervention, and delayed post-test to measure retention effect. One-way ANOVA and repeated-measures ANOVA were used to measure the effect. The findings reveal that significant differences were detected in immediate post-tests of direct and indirect WCF groups which indicate that both WCF strategies can enhance participants’ collocational competency. Additionally, the findings also show that direct WCF strategy greatly affects participants collocation errors despite both groups performed better than the control group. This study demonstrates that retention effect was detected in the group that received direct WCF while the indirect WCF group was not able to retain - in delayed post-test. Recommendation is also discussed for Future directions of studies.Â

Positive Effect

The primary aim of this study is to investigate the effectiveness of direct and indirect written corrective feedback (WCF) on English collocational competency of high-performing ESL learners. The study also sought to compare possible differences in the effect of two WCF strategies that help the researcher in identifying the appropriate WCF strategy in improving learners’ collocational competency in the context of the study. Additionally, retention effect of WCF is also investigated in delayed post-tests. Eighty-eight high-performing ESL learners of a public university participated in the quasi-experimental study of two experimental groups and one control group. A series of test namely pre-test, immediate post-test and delayed post-test was administered to collect the data. The groups are labelled ‘Direct group’ that received direct WCF treatment (n=33), ‘Indirect group’ that received indirect WCF (n=25), and ‘Control group’ that received no treatment (n=25). A set of collocation test that was developed by Gyllstad (2009) was adopted and a pilot test was conducted prior to the actual study. The participants were tested in three point of time (pre-test, immediate post-test, and delayed post-test). The findings indicate that there is a positive effect of direct and indirect WCF strategies on collocational competence. Furthermore, direct WCF has the most effect in improving collocational competency of the participants. Finally, both WCF strategies are proven statistically in retaining their effects as demonstrated in the results of delayed post-test. Suggestion for future studies are also discussed.

SUMMARY Objective The purpose of the study was to evaluate the nanoleakage and bond strength of different self adhesive systems cured with a modified-layering technique (MLT) to dentin of weakened roots. Methods Twenty-one maxillary incisors were decoronated and then root canals were instrumented and obturated with the cold lateral compaction technique. Weakened roots were simulated by flaring root canals until only 1 mm dentin thickness remained. Teeth were distributed into three groups. The canals were backfilled with Vertise Flow (VF group), a self-adhering system, following a modified-layering technique using two light-transmitting posts, sizes 6 and 3. DT Light Post size 2 was cemented using the same material. Remaining roots were prepared and cured in the same way as the VF group. However, in the TS/MF group, Clearfil Tri-S Bond (TS) adhesive and Clearfil Majesty Flow (MF) composite were used, while in the ED/PF group, ED primer II (ED)/Panavia F2.0 (PF) were used. After one week of storage, each root was sectioned to obtain six slices (two slices from each root third: coronal, middle and apical) of 0.9 ± 0.1 mm thickness. Interfacial nanoleakage expression was analyzed using a field emission scanning electron microscope (FEG-SEM), and the micro push-out bond strength (μPOBS) was measured at different root regions. Modes of failure were also determined using SEM. Data were statistically analyzed using two-way analysis of variance with repeated measures and Tukey post hoc test (p≤0.05). Results With MLT, all adhesive systems showed nanoleakage. For μPOBS, there was a statistically significant effect for adhesive systems (p<0.001) but not for root region (p<0.64) or for their interaction (p=0.99). Tukey post hoc test revealed that the bond strength of the VF group was significantly higher than the TS/MF and ED/PF groups for all root regions. Conclusion All of the tested self-adhesive systems cured using MLT had slight nanoleakage and were not sensitive to root regional differences. Self-adhering systems had higher bond strength than self-etch adhesives.

Background and Aim: One of the common behavioral disorders of hearing-impaired child­ren is aggressive behavior, which can affect soc­ial adjustment in their adolescence. This study was designed to investigate the effectiveness of group counseling based on problem-solving on aggression and social adjustment of hearing-impaired students. Methods: This study is quasi-experimental with pretest posttest design and a control group. The study population was all adolescents with hear­ing impairment referred to Yazd Speech The­rapy Centers, Yazd City, Iran. A total of 30 stu­dents were selected from the referred hearing-impaired students with high aggression and low social adjustment. Then they were randomly assigned into control (n = 15) and experimental (n = 15) groups. The study instruments were the California social behavior and Buss and Perry aggression inventory. The group couns­eling based on problem-solving intervention consisted of 7 one-hour sessions, presented for the experimental group. We analyzed the obtai­ned data by repeated measures analysis of cova­riance. Results: Group therapy based on problem-solving can reduce aggression (p < 0.001) and increase social adjustment (p = 0.04). Conclusion: The professionals in this field are recommended to use group therapy based on problem-solving.

INTRODUCTION: The enhancement of nurses’ risk perception plays a significant role in their preparedness during disasters and emergencies. Therefore, this study aimed to investigate the effect of educational workshops on disaster risk perception in nurses METHODS: This randomized controlled field trial study included 62 nurses working at Razi Hospital, Birjand, Iran. The participants were divided into intervention and control groups. The intervention group was then requested to participate in a one-day intensive educational workshop based on the current national standards. The workshop content included a combination of lecturing methods, round-table exercises, and film display. The data were collected using the demographic characteristic form and researcher-made questionnaires measuring the nurses’ risk perception during disasters and emergencies. Subsequently, the data were analyzed using independent t-test, repeated measures analysis, and Bonferroni post hoc tests. FINDINGS: The mean total score of risk perception were significantly higher in the intervention group before, immediately, and two months after the workshop session, compared to those in the control group (P˂0.001). CONCLUSION: The implementation of nurses’ national preparation program during disasters and emergencies can result in an increase in the nurses’ risk perception during these events. Therefore, regarding the importance of nurses’ preparedness in confrontation with disasters and emergencies, it seems necessary to integrate the National Preparedness Program into the educational programs immediately after recruitment and in the form of in-service courses.

Objective: To verify the effect of recreational soccer on bone mineral density and sarcopenia in the elderly. Methods: Fourteen elderly people aged 65.9 ± 3.4 years were selected. They were separated into two groups: the intervention group and the control group; the intervention group played recreational soccer for 12 weeks on two days of the week. Assessments were performed for bone mineral density and body muscle mass before and after the intervention. For statistical analysis, the repeated measures ANOVA with Bonferroni’s post hoc test was used. Results: After 12 weeks, there was a significant change in bone mineral density in the region of the total femur (p = 0.020). Analyzing the participants’ sarcopenia, no significant results were found after the intervention period. Conclusion: Playing recreational soccer causes a significant improvement in the total femur and maintains bone regions in the spine, whole body, and femoral neck. Also, it promotes a removal from the threshold for sarcopenia screening in the elderly.
