Academic writing is not just about presenting a set of ideas, but through the act of writing, the authors position themselves as individuals having particular identities which mostly reflect the dominant sociocultural values and practices of the discourse communities in which they are living and performing. The present study, using a mixed method approach, attempted to explore the evidences of voice and subject positioning, as reflections of authorial identity, in the argumentative writings of 41 advanced Iranian EFL learners. At first, the relationship between voice intensity and overall writing quality of the participants was assessed and the results indicated a positive relationship between the constructs. The multiple regression analysis conducted also revealed that assertiveness, as one of the main subcomponents of voice in writing, had the highest level of contribution in accounting for the writing competence of the learners. Afterwards, some representative instances of subject-positioning (i.e., ideational, interpersonal and textual) in the written texts were identified and discussed based on the ideological context of the study since it is believed that authorial identity and voice can vividly reflect the overall ideology of the specific discourse community in which they are constructed. Finally, it was suggested that raising the awareness of learners and even instructing them about the significance of authorial identity, voice and subject-positioning in writing can assist them in constructing more authentic texts in terms of idea presentation, consideration of readers and specific textual and linguistic features used.

پژوهش حاضر به بررسی تاثیر داده محور بر تشخیص و تولید هم آیی ها ی زبان آموزان با سطح توانش انگلیسی بالا و پایین متوسط پرداخت. همچنین تاثیر ثانویه داده محور بر هم آیی های ثانویه (هم آیی هایی که در واژه یاب گنجانده نشده بودند ولی به صورت مستتر در تکالیف استفاده شده بودند) نیز مورد بررسی قرار گرفت. نگرش زبان آموزان نسبت به نقش واژه یاب در یادگیری هم آیی ها و تغییر نگرش آنها در طی فرایند پژوهش نیز از طریق مصاحبه مورد ارزیابی قرار گرفت. حدود 40 زبان آموز ایرانی به دو گروه آزمایشی و گواه تقسیم شدند. هر گروه به دو زیرگروه سطح توانش بالا و پایین نیز تقسیم شدند. گروه آزمایشی به مدت 10 جلسه به واژه یاب دسترسی داشتند تا تکلیف دوباره نویسی را انجام دهند. نتایج حاکی از آن است که زبان آموزان با سطح توانش بالا بیشتر از زبان آموزان با سطح توانش پایین از تاثیر اولیه و ثانویه واژه یاب بهره مند شدند. هر دو زیرگروه، نگرش مثبتی به تاثیر واژه یاب در یادگیری هم آیی ها داشتند و این نگرش با گذر زمان پررنگتر شد.

Predicting students’ performance in a course is one of the major aims of educational data mining systems. In the present study, two and three-layer artificial neural networks (ANN) and neuro-fuzzy systems (NFS) were used to predict Iranian EFL learners’ final scores and compare them with scores given by their instructor. Sixty-six students’ scores in an English reading comprehension course comprising of five sub-scores of midterm (out of 40), quiz (out of 60), final (out of 50), class participation (out of 5) and bonus (out of 2) were used for training the systems. Two and three-layer ANNs and an NFS were trained to predict students’ final scores using training data. Researchers compared the students’ final scores given by their instructor and those achieved through the ANNs and NFS. The results showed that the NFS could predict and deliver scores that were closer to the linear sum of students’ scores. Moreover, three-layer ANN had a better performance than the two-layer ANN. According to these results, data mining techniques could deliver an accurate estimate of students' abilities in a particular course.

Developing a learner’s ability to communicate in a second language is the goal of communicative language teaching (CLT). Many EFL teachers now accept and employ CLT as a teaching method. Although teachers’ views have a significant influence on how they practice CLT, there haven’t been many studies about teachers’ attitudes about CLT in a specific context, such as Iran. This was revealed through a study of related literature. The current study sought to examine how EFL teachers felt about CLT. The first aim of the present study is to ascertain how EFL teachers feel about CLT. Examining the fundamental causes of instructors’ attitudes is the second goal. Thirdly, determining whether there is a disconnect between instructors' perceptions about CLT and their classroom behavior. The researchers employed a mixed-methods strategy in this study. The study included 30 EFL instructors. Three phases made up the research design: firstly, a questionnaire for gathering quantitative data was used, then interviews and observations were used for gathering qualitative data. The findings of this study showed that, in general, EFL teachers had positive attitudes about the CLT’s tenets and exhibited CLT’s traits in their teaching. There was not much of a discrepancy between the teachers’ perceptions about CLT and their actual classroom actions. This study offers valuable insights that can inform curriculum development, teacher training, and policy decisions, ultimately enhancing the quality of English language education in Iran and similar contexts around the world.

This study examined the effect of rehearsal, strategic, and online planning on the intermediate undergraduate EFL learners’ writing complexity, accuracy, fluency (CAF), lexical variety, and the cognitive psychological performance of attentional allocation to linguistic aspects during planning . To this end, 80 intermediate university students were randomly divided into three experimental groups and one control group. The participants’ performance was compared based on measures of Wigglesworth and Storch’s (2009) fluency, Storch and Wigglesworth’s (2007) accuracy, Foster and Skehan’s (1999) complexity, McKee , Malvern, and Richards’ (2000) vocd-D model of lexical diversity. The study focused on rehearsal, strategic, and online planning in argumentative writing tasks. Retrospective interviews were conducted right after task performance to examine the participants' attentional allocation under three planning-time conditions. It was revealed that rehearsal task planning resulted in higher CAF and lexical variety in comparison to the other groups. Noticeable variation was also evidenced in the participants’ attentional allocation in terms of CAF across different time planning conditions. It was also shown that the learners paid more attention to the conceptualization of ideas during pre-task planning through sentences or clauses while performing a task. Little attention was paid to formulizing complex or accurate utterances. The findings have numerous pedagogical implications for EFL teachers, university instructors, and EFL students.
