خواندن و درک مطلب یکی از موارد اساسی و مهم برای دریافت معنی از متن می باشد. تاکید بر مهارت خواندن فراگیران زبان های خارجی یکی از مهمترین موضوعات متدولوژی در زمینه آموزش زبان است. یکی از مشکلات فراگیران ایرانی عدم تمایل آنان در مواجه با تعامل با متن های خواندن و درک مطلب می باشد، در حالی که بیشتر متون انگلیسی در ایران بر اساس خواندن و درک مطلب طراحی شده اند. برای اینکه مهارت خواندن نقش اساسی در یادگیری زبان دوم داراست. اما کلاس های خواندن متون انگلیسی برای دانش آموزان خسته کننده به نظر می رسد در حالی که بیشتر دانش آموزان علاقمند اند موقعیتی پیدا کرده تا توانایی خودشان را نشان دهند و به سوالات معلم جواب دهند. لذت بخش نبودن کلاس ها به علت عدم آگاهی معلمان از روش های صحیح تدریس خواندن و درک مطلب زبان انگلیسی می باشد. تدریس زبان دوم با استفاده از روش «تکلیف-محور» یک روش موثر در بهبود دانش زبانی و درک مطلب فراگیران شناخته شده است. هدف تحقیق حاضر تعیین تاثیر تدریس فعالیت های آموزشی در قالب تکلیف - محور بر درک مطلب زبان آموزان ایرانی بوده است. جامعه آماری پژوهش 60 نفر فراگیر زبان انگلیسی از آموزشگاه خصوصی بوده است. با توجه به حجم کم جامعه صدرصد جامعه به عنوان نمونه انتخاب گردید. سپس نمونه آماری به دو گروه مساوی؛ گروه کنترل و آزمایش تقسیم شدند. یک گروه با روش های سنتی تعلیم داده شده و گروه دیگر با استفاده از تدریس فعالیت تکلیف محور تعلیم داده شد. تحلیل آماری مطالعه نشان داده است که بین دو عملکرد گروه ها تفاوت معنی داری وجود دارد.

Technology mediated learning brings together the users with shared interests. This method makes learners informally engaged in language learning. This study intended to investigate the effect of technology mediated instruction on cognitive scaffolding, academic performance and motivation. Employing a quasi-experimental research, 80 learners from two intact classes at Islamic Azad University, Osku Branch were selected as the experimental and control groups. Telegram as a tool was used in the experimental group, while the control group received traditional way of instruction. Critical ethnography approach was implemented to consider the amount of cognitive scaffolding. To measure the students’ motivational level in both groups, Course Interest Survey (CIS) was administered at the end of the semester. The total average score for each group was calculated. To compare students’ academic achievement, their average scores in the final academic test were considered. An Independent samples t-test in was used to compare the mean scores. The results indicated that technology mediated learning brought about cognitive scaffolding and the students in the experimental group outperformed the control group in terms of motivation and academic achievement. The results of the study suggest that to bring about academically successful students, practitioners should use technology mediated instruction.

This study explored both teachers’ and learners’ perceptions of teachers’ pedagogic strategies which may engender willingness to communicate (WTC) in an English as a foreign language class and the difference between their perceptions to detect how convergent or possibly how divergent these are. The project used a convenience sample of 300 students taking an intermediate English course and their teachers (N=60) in several English Language Institutes in Tabriz, Iran. The instruments included a Likert scale questionnaire on teachers’ pedagogic strategies and learners’ WTC completed by both teachers and learners. Based on the data collected from the questionnaires, it was revealed that the teachers and learners agreed on the role of teachers’ wait time in learners’ WTC but not on the other strategies such as motivating strategies, error correction strategies, and teachers’ congruence. The findings of the study have important implications for teachers in terms of reconsidering their pedagogic strategies to play their facilitating roles in engendering students’ WTC in the class. The results also have the implications for EFL teacher education in the new era of communication.

Despite widespread interest and research among applied linguists to explore metadiscourse use, very little is known of how metadiscourse resources have evolved over time in response to the historically developing practices of academic communities. Motivated by such an ambition, the current research drew on a corpus of 874315 words taken from three leading journals of applied linguistics in order to trace the diachronic evolution of stance markers in methodology section of research articles from 1996 to 2016. Hyland’s (2005b) model of metadiscourse was adopted for the analysis of the selected corpus. The data were explored using concordance software AntConc (Anthony, 2011). Moreover, a Chi-Square statistical measure was run to determine statistical significances. The analysis revealed a significant decline in the overall frequency of stance markers in methodology section of RAs. Interestingly, this decrease was entirely due to the overall decline in the use of self-mentions. Approaching interactional dimension of academic writing from such a diachronic perspective, it might be argued that the very selective use of stance markers by academic writers over time means metadiscourse does not operate in vacuum and is sensitive to changes within disciplines and their academic practices.

تعداد بازدید : ۴۴۲ تعداد دانلود : ۲۶۸
This quasi-experimental study investigated the effects of input-enhancement and production of sentences, containing the target structures, on learning grammar by Iranian Intermediate EFL learners. Sixty male students in three input, output, and control groups participated in the study. After checking the homogeneity of the participants with a proficiency test, the researchers administered a pretest. Input-based group received input enhancement within reading texts in which the target structures were highlighted with different techniques such as bolding and underlying. The output-based group were required to produce some sentences including target structures based on reading texts. The control group received traditional grammar instruction. The results of ANCOVA revealed that both experimental groups learned the target structures better than the control group; however, the input-based group outperformed output-based group in learning target grammatical structures. The findings of the study suggest the widespread use of input-enhancement, as one of the techniques of focus on form, plays a significant role in enhancing grammatical accuracy.

Intercultural contact (IC) among students has received a great prominence in EFL and ESL contexts in recent years; therefore, this study was an attempt to modify and validate a questionnaire as an instrument to elicit the resources from which Iranian EFL students obtain their IC information. To reach this aim, a modified version of Peng and Wu’s questionnaire with 26 items and five factors was administered among 200 male and female Iranian EFL students from different language institutes in Tabriz, Iran. To determine the reliability and validity of the modified questionnaire, the statistical analyses of the model and fitness of the questionnaire were conducted by SmartPLS3 software. The results of reliability analyses using three measures of Cronbach’s alpha, combined reliability (CR) and average variance extraction (AVE) demonstrated that the questionnaire has a good reliability. Moreover, the results of construct crossvalidated communality (Q²) proved the construct validity of the questionnaire. Additionally, the results of correlation coefficient matrix and p value for all the latent variables demonstrated that all the paths and relationships in the model are significant and the model is a good fit. This study also clarifies the implication of such a questionnaire for ELT and presents some suggestions for future studies.

The effects different awareness-raising techniques might have on language learners’ performance have been studied by many researchers. The present study specifically focused on improving EFL learners’ oral narrative task performance in terms of accuracy, fluency and complexity by awareness raising through semantic fields. The participants in the study included 40 intermediate learners whose initial homogeneity in terms of language proficiency was assessed via a Preliminary English Test (PET). They were further randomly assigned as one experimental group and one control group, each comprising 20 participants. The amount of instructional time was 17 sessions, during which the participants in the experimental group received an awareness raising technique through 'semantic fields'. Before and after the treatment, an oral narrative test was administrated. The results of the data analysis revealed that the experimental group which received the awareness raising technique outperformed the control group in three measures of accuracy, fluency and complexity on their performance. The participants showed significant improvements in language proficiency as they retold the narratives. The findings of the present study can create the floor for researchers to go deep through the EFL contexts and find more about the probable effects awareness raising techniques might have on language learning and teaching.

This study reports psychometric properties and derivation of norms for a Persian version of the Multiple Intelligence Developmental Assessment Scales (MIDAS) for Adults. After examining and confirming equivalency between English and Persian versions, translated and validated by Saeidi, Ostovar, Shearer, and Asghari Jafarabadi (2015), the scale was administered to a sample (N = 2146), including students, undergraduates, graduates, and adults from different provinces in Iran. The participants were at least 19 years old and above (M = 29.40, SD = 2.26). Out of 2146 samples, 1103 females and 1043 were males. To examine the validity and reliability properties of the scale, exploratory and confirmatory factor analyses, Cronbach Alpha (α) reliability correlation coefficients, and corrected item-total correlations were employed. Exploratory factor analysis using varimax rotation identified eight principal components, which accounted for 67.21% of the variance for 115 items. The internal consistency coefficient (α = .92; ranging from 0.89 to 0.93) was also very high. The confirmatory analysis generally replicated the original conceptualization of the MIDAS. According to the results, the Persian-MIDAS-adults questionnaire has good psychometric properties in the research community and can be safely used as a valid tool to assess MI in Iran.

تعداد بازدید : ۳۰۱ تعداد دانلود : ۱۳۳
This qualitative study aims to investigate the sources of burnout from Iranian EFL teachers’ perspectives. To this end, thirty-four Iranian male and female EFL teachers participated in the semi-structured interview to comment on the burnout sources and then rank them in terms of priority. Also, one hundred teachers responded to an online open-ended questionnaire. The coding scheme revealed two external and internal nodes, five themes, and fifteen subthemes. Under the external node lay financial, organizational, and teacher training problems. The internal node involved teachers’ psycho-affective traits and personal life affairs. The results showed that external sources outweighed the internal ones. Among the external sources, teachers’ low pay, the supervisor’s maltreatment, and workload, and among the internal ones, teachers’ low problem-solving abilities, low motivation and self-efficacy held high ranks. No one attributed burnout to teachers’ gender and age, and almost all participants unanimously criticized the educational administration system of Iran for not providing teachers with the necessary means of burnout recognition and prevention. The study has implications for educational policymakers and practitioners.

تعداد بازدید : ۲۸۸ تعداد دانلود : ۲۱۶
This study attempted to compare typed and handwritten essays of Iranian EFL students in terms of length, spelling, and grammar. To administer the study, the researchers utilized Alice Touch Typing Tutor software to select 15 upper intermediate students with higher ability to write two essays: one typed and the other handwritten. The students were both males and females between the ages of 22 to 35. The analyses of the students’ scores in the three mentioned criteria through three paired samples t-tests indicate that typed essays are significantly better than handwritten ones in terms of length of texts and grammatical mistakes, but not significantly different in spelling mistakes. Positive effects of typing can provide a logical reason for students, especially TOEFL applicants, to spend more time on acquiring typing skill and also for teachers to encourage their students with higher typing ability to choose typed format in their essays.

Effect of Oral Corrective Feedback on Iranian EFL Learners’ Phonological Uptake and Retention

کلید واژه ها: corrective feedback recast elicitation Uptake Retention

حوزه های تخصصی:
تعداد بازدید : ۲۸۱ تعداد دانلود : ۲۵۶
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 comparative effect of collaborative strategic reading (CSR) and metacognitive reading strategy (MRS) on the reading comprehension of Iranian extrovert and introvert EFL learners. To achieve the purpose of this study, a sample IELTS was administered to 325 students studying at Marefat Language Academy in Tehran from whom 225 were selected based on their performance on that test. Next, the above students sat for Eysenck Personality Inventory questionnaire to determine their level of extroversion and introversion. As a result, a total of 150 learners (75 extroverts and 75 introverts) were selected as four experimental groups and two control groups. The four experimental groups, comprised of 1) 25 extroverts undergoing CSR, 2) 25 extroverts receiving MRS, 3) 25 introverts undergoing CSR, 4) 25 introverts undergoing MRS while the two control groups, with 25 extroverts and 25 introverts, the learners experienced the conventional procedure of teaching reading comprehension in the language school. Ancova and two-way Ancova were conducted which revealed introvert learners with MRS outperformed the extrovert with MRS, introvert and extrovert with CSR, and control groups, suggesting a decisive role for personality traits in reading comprehension classes with different reading strategies instruction.

The current study was an attempt to investigate the impact of grouping type on the grammatical accuracy of Iranian EFL learners in collaborative writing. Through administering the Michigan Test of English Language Proficiency, 64 female university students available participated in this study and were assigned to two groups--heterogeneous and homogeneous. The treatment process lasted 12 weeks of collaborative writing and revising, with emphesis on the development of the the participants’ written grammatical accuracy. They were pretested and posttested through a descriptive free writing measure. The results revealed that the participants in both groups had higher posttest scores. Using ANCOVA, it was found that there was a differential effect of grouping type on the grammatical accuracy of homogeneous and heterogeneous pairs, indicating that the participants in heterogeneous group had significantly higher posttest scores than those in homogeneous group. Furthermore, although the grammatical accuracy of both groups increased, a significant difference was observed between them, revealing that the participants in heterogeneous group outperformed those in homogeneous group. The findings of this study can be interpreted in terms of the sociocultural theory and Vygotsky’s idea of the zone of proximal development.

Group Dynamic Assessment (G-DA), introduced by Poehner (2009), applies mediation through concurrent and cumulative approaches. This study investigated the effect of the two approaches on Iranian homogeneous and heterogeneous EFL learners' auditory memory in listening tasks. Eighty female intermediate EFL learners were chosen as the participants of the study. They were assigned to two groups of forty homogeneous and forty heterogeneous learners. Then, each group was divided into two experimental groups with twenty participants in each. Homogeneous and heterogeneous participants were assessed through both concurrent and cumulative approaches. To find out the main and interaction effect of concurrent and cumulative G-DA and homogeneity and heterogeneity of EFL learners, the post-test scores of the participants were analysed through a two-way ANOVA.  The results indicated that G-DA approaches on the one hand and homogeneity and heterogeneity of EFL learners on the other, had both significant main and interaction effect on EFL learners' auditory memory.  For the independent effect of both approaches, a one-way ANOVA was also used. The results indicated that cumulative G-DA had more significant effect than concurrent one on heterogeneous EFL learners' auditory memory. ANOVA analysis also proved that the two approaches did not differ in their effect on homogenous learners.
