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.   

Due to the importance of idioms, many researchers and teachers have long sought to find ways of making idiom teaching and learning more effective. This study compared three visual mnemonic devices (pictures, mental imagery, and movie clips) in terms of their effect on EFL learners’ recognition and recall of English idioms. Ninety intermediate level EFL learners who were preparing themselves for IELTS participated in this study. They were in three groups of thirty members each. Each group was taught idioms using one of the afore-mentioned visual mnemonic devices. Receptive and productive tests of idioms were administered to all groups after the treatment. The one-way ANOVA procedure was used to analyze the collected data. The results revealed statistically significant differences among these devices, with pictures method being the most effective on both recognition and recall of idioms. The findings of the study can have significant theoretical as well as pedagogical implications for language researchers, textbook designers, curriculum developers, teachers, and language learners. 

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.

Meta-discourse markers are an inevitable part of oral proficiency which improve both the quality and comprehension of learners’ speech. While studies of oral meta-discourse have been conducted since the 1980s in a European or US context, they have remained relatively untouched in Iran. Therefore, this study aimed to seek the impact of both explicit and implicit teaching of formal meta-discourse markers on EFL learners’ oral proficiency. To this end, the quantitative data were collected from ninety upper-intermediate students at Shiraz University Language Center. Two groups went through an instruction for an eight-session treatment. However the experimental group ‘B’ (N=45) were instructed the formal meta-discourse markers implicitly, the target formal meta-discourse markers were taught to the experimental group ‘A’ (N=45) explicitly. To compare the participants’ performances, an SOPI (Simulated Oral Proficiency Interview) posttest was administered. The results revealed that the instruction of meta-discourse markers had a positive effect on the learners’ oral outcome. Moreover, the findings showed that learners who received explicit method of teaching formal meta-discourse markers could perform better in speaking than learners who received implicit instruction. The findings can have pedagogical implications for EFL educators and materials developers to enhance learners’ oral proficiency. The findings also provide important insight into the effect of teaching discourse markers and raising learners’ awareness through explicit instruction to make pupils produce more cohesive and coherent speech.

Grades represent one of the most common sources of evidence of student achievement in classrooms, though their relationship with test scores has remained understudied, particularly in settings such as in Iran, where English is taught as a foreign language. The purpose of this study was to investigate the relationship between graded and tested achievement with respect to gender and proficiency level differences. Teacher-assigned grades and standardized achievement test scores of 693 Iranian learners of English taught by 15 teachers were examined. Primary analyses focused on the validity of teacher grades and the subsequent Pearson correlation coefficients revealed that grades associated positively with externally-validated test scores obtained from reliable tests, an indication of the validity of teacher grading. Additionally, the results of independent-samples t-tests showed that female students outperformed male students on achievement tests, but with fluctuations across proficiency levels. Higher proficiency levels gave male participants an advantage over female participants in achievement tests. Moreover, male teachers were found to grade female participants more accurately than their female counterparts. Implications are discussed for informing teachers about the validation of their grading practices, as well as for teacher education programs and teachers’ professional development.
