Despite growing interest in the studies on Zone of Proximal Development (ZPD), its operation in the forms of individualized and group-wide has been controversial. To cast some empirical light on the issue, this study was designed to quantitatively and comparatively study the applicability of the two scenarios of ZPD-based instructions to the writing complexity of Iranian EFL learners in terms of learners' types (low vs. high scorers). To this end, 118 EFL learners identified as homogeneous based on the TOEFL ITP test were randomly assigned into two equal experimental groups (individualized ZPD- and group-wide ZPD-based groups) which respectively received compatible instructions utilizing conference writing (as an individual scaffolding technique) and low- and high-structured writing templates (as a whole-class scaffolding technique). The treatments were allocated to the groups in a random manner within homogeneous blocks. Prior to and after the treatments, three tests (two writing tests and one ZPD test) were administered to measure both groups’ writing complexity and their ZPD levels. A ZPD test was also administered in the mid of treatments. The non-parametric analysis of covariance (ANCOVA) revealed that the individualized-ZPD-based instruction is constructive to the writing complexity of the low scorers, while the group-wide ZPD-based instruction shows not much constructive to the writing complexity of the high scorers. The findings pointed to the use of ZPD-based instructions in TEFL writing in meaningful contexts and thereby showing impacts made on the writing complexity of learners. The study, indeed, yields support to the feasibility of group-wide ZPD measurement along with an individualized ZPD approach.

In the realm of second language acquisition (SLA), task-based language teaching (TBLT) and input enhancement (IE) have been the focus of a great number of studies. However, the idea of investigating the effects of focus on form instruction through input-enhanced tasks along with pre-task planning time as one of the features of task-based language teaching has been rarely explored in the field of SLA. Therefore, the current research set out to examine the impacts of focus on form instruction via textually-enhanced reading tasks along with strategic pre-task planning on L2 learners’ grammatical development in terms of learning English passive voice. For the purpose of the study, 60 intermediate learners of English were selected and divided into two groups of thirty namely as enhanced and unenhanced. Then, each group was divided into two sub-groups of fifteen as +planning and -planning. The participants were provided with a pretest prior to the treatment, then, they were instructed via the materials chosen for the purpose of the study for ten sessions and at the end they were provided with the posttest of the study. Their performance on the pretest and posttest were analyzed to find out the possible effects of the instruction provided throughout the treatment phase. The results revealed that learners who were exposed to enhanced reading tasks along with strategic pre-task planning time outperformed the other learners. The findings of the present study can be of use for language teachers, syllabus designers, and task designers.

The current study aimed to explore the nature of discursive strategies academics would use to share their specialist knowledge to both specialists and non-specialists. To this end, a corpus of 40 academic research articles and 40 popular science articles were randomly selected from the archive of four English international peer-reviewed journals and four English popular magazines and newspapers in the field of Nutrition. Appraisal Theory (Martin & White, 2005), a discourse framework to examine evaluative and/or persuasive language, was used to analyze the data. The results revealed significant areas of similarity and difference in terms of certain discursive elements leading to discernible degrees of persuasion. The findings imply that in order to develop a scientifically literate society, scientists should appeal to diverse discourse resources to provide the public with their findings in an informative and entertaining way. The results of the study carry some pedagogical implications for EAP courses held in EFL settings since being able to both comprehend and produce scientific texts of different professional levels at international scale seems to be a requirement for the future scientists.

Traditional literature teaching is usually a passive process as students normally perform the role of listeners. This research proposes to alter the students’ role to active learners by assisting them to produce and stage an English children’s drama. This study is student-centered and attempts to adopt workshop and drama practice to enhance students’ participation in the classroom. Different from traditional teaching methods, constructivist pedagogy enables learners to recognize and strengthen their self-learning abilities. Often discussed in constructivist pedagogy, Lev Vygotsky’s works are especially related to this research. Even though the application of Vygotsky’s theory to teaching is beneficial to students, relevant studies are scarce in higher education. This paper then proposes to apply Vygotsky’s idea of zone of proximal development and scaffolding approach to cultivate students’ ability to produce an English children’s drama. Through the support of capable others, the learners achieve a deeper understanding of drama/literature and through the scaffold approach, students steadily leave the need of assistance behind, are able to work independently and autonomously, and become more capable than their previous selves.

This study investigated the comparative effects of audio-visually prompted collaborative dialogue on the listening comprehension development of symmetrical, asymmetrical, and asymmetrical teacher-fronted EFL learner groups. Besides, it explored the attitude of the participants of the groups concerning the effectiveness of collaborative dialogue for their listening comprehension improvement. The participants of the study were 120 Iranian female EFL learners who were conveniently chosen from several English language institutes and put into three experimental and one control groups, each with 30 learners. In the first experimental group, coequal learners engaged in collaborative dialogue. In the second experimental group, the expert peer(s) and less knowledgeable peers applied collaborative dialogue, and in the third experimental group, in addition to the peers, the teacher was involved in collaborative dialogue with the group members. As for the control group, the collaborative dialogue was abandoned and the participants worked individually. Quantitative and qualitative analyses revealed that collaborative dialogue in asymmetrical teacher-fronted, asymmetrical peer and symmetrical peer groups were respectively the most effective procedures for listening comprehension development of the EFL learners. Also, it was found that the participants of the asymmetrical teacher fronted group had a more positive attitude towards the efficacy of audio-visually prompted collaborative dialogue compared with asymmetrical and symmetrical peer groups. The findings underscore the cognitive and affective efficiency of a more knowledgeable source, either a teacher or a peer, in asymmetrical dyadic interactions for the less knowledgeable partners' ZPD sensitive development.   

The current research examined the use of lexical bundles in the result sections of research papers by Iranian non-native writers in the field of applied linguistics. The WordSmith Software was applied to identify lexical bundles. In addition, the two analytical frameworks Biber et al. (2004) and Ruiying and Allison (2003) were used to categorize the bundles with regard to their structural features and their moves and steps. Moreover, with the aid of concordance, the identified clusters were analyzed and categorized according to their communicative functions. The results of the current research showed that Iranian writers relied heavily on the use of specific formulaic bundles to perform the communicative functions associated with the moves and steps. The findings also revealed that four moves out of six moves were mostly used by Iranian authors. Moreover, the researchers found that the extensive range of formulaic clusters used to demonstrate Move 2, Reporting results, the least bundles occurred in Move 4, Summarizing results, and also no clusters were used in Move 5, Evaluating the study along with Move 6, Deductions from the research by Iranian writers. The findings of this study boost the awareness of formulaic sequences usage for novice writers in particular discourse and communicative function.

Google Translate , a free multilingual machine translation service, developed by Google has attracted the attention of countless users due to its ease of use through modern means of mass communication, and has become the only translation tool in some areas. However, compared to human translation, these machine tools have not yet been able to deliver high-quality translations due to the complexity of translation process. Therefore, studying the modifications of machine translated texts is of great importance. Therefore, the current study aimed to explore the types of linguistic modifications of the texts translated from Persian into English through Google Translate. To this end, the abstracts of ten unpublished Persian literary articles intended to be submitted to Iranian journals were selected for the analysis. The selected abstracts were initially translated into English (target language) through Google Tra n slate from Persian (source language). To identify the kinds of changes needed to make them academically acceptable, the machine translated texts were all post edited. Then, the original Google translated texts and their post edited versions were compared to figure out the types of the applied modifications. The results of this qualitative study indicated that the linguistic post edition modification of the texts included tense, literal translation, redundancy, collocations, deletion of the main verb, word-choice and proper nouns.
