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.   

Designing appropriate materials and activities to enhance vocabulary learning is one of the primary goals of language courses. Among the claims about efficient pedagogical tasks is the Involvement Load Hypothesis (Laufer & Hulstijn, 2001) according to which vocabulary development is contingent on the amount of cognitive process a task involves. Building on the previous research on this hypothesis, this study seeks to explore the extent to which three post-listening tasks of different involvement loads along with single-versus dual-mode glosses affect receptive and productive vocabulary learning of advanced English as a foreign language (EFL) learners. The participants (n = 204) listened to an expository text while twenty lexical items were presented through text-only or text-plus-picture glosses. Subsequently, they were assigned to one of the task type groups (sentence writing, gap-fill, and paragraph writing). Paribakht and Wesche’s (1997) Vocabulary Knowledge Scale was employed as the pre and post-tests. The results pointed to the efficacy of dual-mode over single-mode glosses concerning both receptive and productive vocabulary learning. The sentence writing task produced the highest scores in the vocabulary tests, whereas the gap-fill and paragraph writing tasks did not significantly differ. Hence, the results only partially confirmed the Involvement Load Hypothesis. The current study corroborates other studies verifying the modality effect on vocabulary learning and suggests that task type is a significant factor in EFL vocabulary learning.

The current study investigated the distribution of animal terms in the Persian book of Marzbannameh and their metaphoric repetition in the users’ opinions, thoughts, and worthiness. By investigating the Persian book of Marzbannameh as one of the famous literary books which is rich of animal conceptual metaphors, a corpus of 376 animal terms in content has been chosen and analyzed. Four raters who were the Persian Literature teachers analyzed accurately the pertinent book for evaluating the available animal metaphors. And, two other raters who were the Persian Literature professors were asked to study the decisions and present the final propositions if they had different ideas about a concept. Moreover, as a supporting research method, focus groups were engaged by the Persian Literature teachers and professors to give their ideas and thoughts about the positive and negative qualities of the contained animals in the selected book. The results offered that animals are not distributed alike in this book, are used with diverse conceptualizations and stood for both positive and negative connotations. Also, it was found that the domestic animals generally have positive characteristics; however, some of them violate this rule, connoting just negative characteristics. After all, the wild animals, except for hawk, generally have negative characteristics.

Mixed in method, the present study investigated whether there was any significant difference between students’and teachers’perceptions of Iranian medical English for Academic Purposes (EAP) students’ language needs. In so doing, 220 EAP students of medicine, 30 subject-matter teachers of EAP, and 20 teachers of English for General Purposes (EGP) teaching medical EAP completed a Likert-scale questionnaire. Fifty of the students and 20 of the teachers also attended a semi-structured interview. The results of both descriptive statistics and inferential statistics indicated that, overall, there was a significant mismatch between the students’and the teachers’perceptions of medical EAP students’ needs. However, both teachers and students perceived reading comprehension as the most important language skill. Moreover, the students, in general, were found not to be satisfied with the EAP program presented to them. The results might prove fruitful for curriculum designers, materials developers, and teachers in (medical) EAP contexts to hear students’voices and to incorporate them in their programs, syllabi, and teaching.

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.

This study investigated the effect of Narrow Reading (NR) on learning mid-frequency words. Vocabulary Size Test (VST) designed by Nation and Beglar (2007) was administered as the first pre-test to 196 students, from among whom 91 students whose vocabulary size ranged between 2100- 3500-word families, , became the target of this study and were randomly classified into four groups. Then another pretest administered was a modified version of Wesche and Paribakht’s Vocabulary Knowledge Scale (VKS) which assessed how well they knew twenty vocabularies derived from the expository and narrative texts. After thirty sessions for direct instruction, VKS was repeated immediately as a posttest to assess vocabulary learning while a month later, VKS was taken as a delayed posttest to assess vocabulary retention. To address research questions, a mixed design factorial ANOVA was conducted. The findings revealed that while the theme was fixed, reading expository texts rather than narrative ones led to the growth in vocabulary knowledge. In addition, the group that read narratives forgot most of the mid-frequency words in the retention phase. As opposed to multi-author texts, reading texts written by one author resulted in a better vocabulary achievement in both learning and retention phases. It was also revealed that there was no interaction between genre and author. In other words, the author was as influential in learning mid-frequency words among expository texts as it was in narrative ones. Finally, it was concluded that NR has a positive effect on learning mid-frequency words.

The present study aimed to examine and validate a rubric for translation quality assessment using Rasch analysis. To this end, the researchers interviewed 20 expert translation instructors to identify the factors they consider important for assessing the quality of students’ translation. Based on the specific commonalities found throughout the interviews, a 23-item assessment rubric was constructed on a four-point Likert scale. More specifically, this study used the Rasch rating scale model for polytomous data to investigate the psychometric properties of the rating scale in terms of dimensionality, reliability, use of response category, and sample appropriateness. Then, a translation exam was administered to 60 translation students at the BA level in Iranian universities. Following this, the rubric was employed to assess the quality of students’ translation. The results revealed that the Rasch model fits the data well. Thus, the findings of the study indicated that the rubric is potentially valid and useful, and can be used as a measure of translation quality assessment in the Iranian context.
