Given the role of lexical knowledge in language learning, strategies for vocabulary learning should be paid more attention in the literature. This study investigated the effects of visualization, drawing, and memorization on Iranian EFL learners' recall and retention of second language vocabulary using a quasi-experimental comparison design . To that end, three intact classes, incorporating sixty students in total , were randomly selected as the experimental groups of this study. Nation’s (2006) vocabulary size test was administered to them to homogenize them in terms of English lexical knowledge. The results of one-way ANOVA demonstrated that there were no significant differences among the three groups in terms of vocabulary knowledge. A piloted researcher-made vocabulary test was administered to the participants as the pretest and post-tests. The one-way ANOVA results showed that there were no significant between-group differences among the groups' performances on the immediate and delayed posttests. However, the results of a repeated-measures ANOVA indicated that the three strategies had a significant within-group effect on the three groups' vocabulary recall, while their vocabulary retention was found to have dropped significantly from immediate to the delayed posttest. All the same, the drawing group had the best performance from the pretest to the immediate posttest, and the control group was the weakest on delayed posttest. Finally, the findings are discussed, and implications are offered for EFL teachers and learners.

The current study used Structural Equation Modeling (SEM) as a statistical technique to test a hypothesized mediating model to uncover the underlying relationship between the L2 motivational self-system, L2 anxiety, and L2 willingness to communicate (L2 WTC). This study is significant because it considers the unique experiences of English as a foreign language (EFL) learner in the era of globalization by incorporating the L2 motivational self-system. The mediating effect of L2 anxiety was also accounted for, providing a deeper understanding of how emotional factors influence L2 WTC. The data were collected through a questionnaire administered to 260 students at six public universities in China. The results showed that (a) two subcomponents of the L2 motivational self-system (ideal L2 self and L2 learning experience) were positive predictors to L2 WTC; (b) the higher the degree to which learners were motivated by their ought-to L2 self, the higher the anxiety of English learning; and (c) L2 anxiety had a suppressing effect between the L2 motivational self-system and L2 WTC. Specifically, L2 anxiety weakens the direct positive effect of the L2 motivational self-system on L2 WTC, leading to a decrease in L2 WTC. Pedagogical implications and future research directions were also addressed.

Genre-based pedagogy has gained a lot of attention since the mid-1980s. Genre is defined in relation to the use of language in conventionalized communicative situations. In this research, there was an attempt to scrutinize the effects of genre-based pedagogy on Iranian medical researchers’ discussion writing ability. To examine the formulated hypotheses, A group of 35 subjects were randomly selected from medical researchers in Zanjan and Tehran Universities of Medical Sciences. Both male and female researchers were invited to this study. A within-group pre-test and post-test design was implemented. The instructional procedures went on for four sessions before the posttest was administered. The results of the paired t-test revealed that genre-based pedagogy had a significant effect on the discussion writing ability of Iranian researchers of medical sciences. Ultimately, in a Focus-group interview, the participants contended their expertise in writing significantly increased due to the treatment sessions. Implications of this study may include genre-based pedagogy in the Iranian ESP curriculum.

The present study scrutinized the association between learners’ perceptions of EFL instructors’ interpersonal behavior and their English language achievement in Amhara regional state public universities, Ethiopia. In this correlational research, 177 participants who were first-year English Language and Literature students were selected using purposive and random sampling. The data were gathered through a questionnaire and an English language achievement test. Besides, the data were analyzed quantitatively using descriptive and inferential statistics, and multiple regression. The findings showed that understanding behavior was perceived as the frequent interpersonal behavior of EFL instructors followed by strict, student freedom, and leadership behavior, respectively. Apart from this, uncertain behavior was found to be the least perceived behavior in the classrooms. In addition, the findings indicated that instructors in the sample areas were less prevailing but more cooperative in the communique process with their learners. In line with relationships, it was found that optimistic and noteworthy correlations between students’ English achievement and their teachers’ understanding and leadership behavior. In the case of its contribution, understanding followed by leadership interpersonal behavior was found to be the most prevailing and substantial variable on the learners’ English achievement. It was, therefore, recommended that instructors should be given training continuously on instructors’ interpersonal teaching behavior and its relationship to students’ language learning.    

The goal of the present study was to realize whether L1 (first language) or L2 (second language) affects the third language (L3) learning. Three mirror-image groups learning English were compared, as early learners of sequential Persian-Arabic bilinguals. The first group used L1 Persian-L2 Arabic languages. The second and the third groups used L1 Arabic-L2 Persian languages. Moreover, the first and the second groups used Persian, and the third group used Arabic as a language of communication. The Oxford Quick Placement Test (OQPT) was administered to select initial L3 English learners. Sixty English learners participated in the study. The translation task and Grammaticality Judgment Test were administered to elicit English attributive adjectives. To compare the performances of the three groups, the non-parametric equivalent of One-Way ANOVA, which was the Kruskal-Wallis test, was used. Mann-Whitney U tests were applied to recognize the probably significant differences among groups. None of the Cumulative Enhancement Model (CEM), the L1 Factor Hypotheses, the L2 Status Factor, and the Typological Primacy Model was confirmed. However, the influence of the dominant language of communication on L3 learning supported data. Groups one and two had better performances in the comprehension and production of attributive adjectives. Group three obtained the lowest mean score. This study lets us determine the influence of earlier acquired languages, Persian and Arabic, on the initial stage of learning L3 English attributive adjectives. The results indicate that the language of communication has a substantial effect on transferring from the first and second languages into the L3 language.  

Toulmin's (1958) model of argumentation and Abdi et al.'s (2010) model of metadiscourse, mapped onto Grice's (1975) Cooperative Principle, are both attempts to elaborate on the process and contribute to the goal of obtaining persuasion. This study is an attempt to integrate the use of metadiscursive and argument strategies to provide a common logical rationale for their employment. Through a qualitative investigation of 40 ELT research articles (RAs), we propose a convergent framework for employing CP-based metadiscourse and argumentation model in RA arguments. As a result, endophoric markers were identified to be used as warrants to meet quantity, while transitions, frame markers, and code glosses were found to be employed as conclusions and data to fulfill manner. Furthermore, evidentials were found to be employed in conclusion, backing, and warrant; hedges were seen to be used as qualifiers; and finally, disclaimers were recognized to be employed in rebuttals; to meet quality. The findings reveal that argumentations are built metadiscursively which has implications for writers and educators. For writers, it could help to develop a deeper understanding of the positive role of metadiscursive strategies in RA arguments and as such could guide a more efficient employment of it to facilitate persuasion. For educators, the findings could provide a model for building and ensuring basic logical and rhetorical characteristics of an argument in academic writing. 

The question of whether specific patterns of impairment across different language modalities are isolated, associated, or doubly dissociated has been a major theoretical issue in aphasiology. In this paper, we describe modality- and task-specific language impairments in a Persian-speaking patient (AG) with ischemic stroke. AG’s overall language impairments were evaluated using the bedside version of Persian Western Aphasia Battery (P-WAB-1), which indicated an Aphasia Quotient (AQ) index of 86. Moreover, his performance on the Reading subtests of the Persian Diagnostic Aphasia Battery (P-DAB-3) indicated a Language Quotient (LQ) index of 60. We also evaluated his word reading, sentence reading, and sentence repetition using the subtests of the Persian version of the Bilingual Aphasia Test (BAT). Based on his performance on these assessment tools during the chronic post-onset time, AG was diagnosed with transcortical motor aphasia. Notably, he exhibited two striking characteristics, namely, (a) a modality-specific dissociation, with severely impaired reading comprehension in the face of relatively spared auditory comprehension; and (b) a set of task-specific agrammatic symptoms in verbal expression and out-loud sentence reading in the context of relatively well-preserved sentence repetition. The general characteristics of our patient’s grammatical violations also highlight certain universal and language-specific agrammatic impairments. The present clinical linguistic data argue against the existence of monolithic speech-related regions in the brain.

The timing of corrective feedback (CF) provision has been a controversial issue in SLA research. Despite widespread research, there is still disagreement on whether the erroneous structures should be addressed immediately or at a delayed time after task completion. This study investigates the comparative effects of immediate and delayed feedback on developing subject-verb (s-v) agreement by Iranian EFL learners. To this end, 28 university students were divided into immediate (n=14) and delayed (n=14) CF groups after the administration of the Oxford Placement Test. The study involved a pre-test, three treatment sessions and a post-test. The two feedback groups received treatments followed by either immediate feedback provided after task completion or delayed feedback delivered after 3 days of task completion. The tests and treatments contained various activities including multiple-choice, cloze, fill-in-the-blanks and picture description task. The results of the analysis of test scores on the pre- and post-tests were indicative of the outperformance of the immediate CF group, implying that the immediate feedback may be more beneficial for developing s-v agreement accuracy than delayed feedback. The findings of this investigation can bear efficient implications for language teachers and researchers.

This study aimed at describing a causal model of variables influencing preservice EFL teachers΄ technological pedagogical content knowledge (TPACK). A descriptive correlational design was used to meet the objective of the study, therefore, 138 (67 male and 71 female) fourth-year student teachers in Teacher Education University were selected through convenience sampling method. A questionnaire including seven sections each of which measuring an aspect of TPACK was utilized. The sections of instrument were borrowed from those validated by Sahin (2011) for evaluating content knowledge, pedagogical knowledge, pedagogical content knowledge, and technological knowledge, and by Chai, et al. (2011) for measuring technological knowledge, technological pedagogical knowledge and TPACK. Path analysis and Pearson correlation were used for inferential statistical analysis. Results showed that there existed significant positive correlations between the TPACK constructs. Additionally, content knowledge and pedagogical knowledge, unlike technological knowledge, were found to have a direct impact on TPACK. Moreover, it was found that, among the measured variables, content knowledge had the greatest total effect on TPACK whereas that of pedagogical content knowledge was the minimum. Therefore, the results of this study have implications for curriculum design, policy decisions and teacher education planning.

Giving consideration to the importance and on-going challenge of vocabulary learning, there is an increasing demand for seeking out new approaches that correspond well with the needs of digital natives. With the rapid advance of technology, deploying innovative approaches such as gamified and flipped mobile- assisted language learning is gaining worldwide popularity. The current study was an attempt to scrutinize the effectiveness of integrating gamification with flipped approach on EFL learners' receptive vocabulary learning. With the aim of carrying out this research, 68 EFL high school students were randomly allocated into an experimental and control group. The required data were gathered by means of pre- and post- tests. Moreover, the obtained data were analyzed through descriptive and inferential statistics including two paired, and one independent samples t-tests. Quantitative findings revealed that the experimental group participants outperformed their non-gamified coequals. Additionally, as post-test scores showed tremendous improvement, it was found that both aforesaid approaches were devastatingly effective in enhancing EFL learners' vocabulary development. The results of this study can be useful for EFL instructors and teachers for giving them insights on how to employ flipped approach for teaching receptive vocabulary.

The statement stated in a multiple-choice question can be developed regarding two types of sentences: Interruptive (periodic) and cumulative (or loose). This study deals with different kinds of stems in designing multiple-choice (MC) items. To fill the existing gap in the literature, two groups of teacher students passing general English courses at Farhangian University were selected based on Cambridge Placement Test. The design of this study was a comparison group design. To verify the effectiveness of the stems, i.e., interruptive and cumulative stems, two types of tests based on the book entitled Thoughts and Notions 2, which was taught in General English classes, similar in content, but different in their stems, were designed. Each test contained 40 items, 25 vocabulary items, and 15 items of reading comprehension. The first group of students was given the test designed using only interruptive sentences as stems. The second group participated in the test, being prepared using only cumulative sentences as stems. After the data analysis via an independent t-test, it became apparent that the first group outperformed the second. Therefore, it was concluded that interruptive sentences as a stem in multiple-choice tests were more reliable and valid than cumulative ones. One of the study implications is that the interruptive stems can be used to assist policymakers and material designers, and language teachers to be considered for future decision making, and designing materials.

The present study aimed at exploring the predictive validity of achievement goals for EFL university students’ attainment emotions, and academic success in the context of Iran. To this end, 440 EFL university students responded to the relevant instruments. The results revealed that learners’ mastery-approach, mastery-avoidance, and performance-approach goals were significantly positively correlated with positive attainment emotions, and negatively associated with negative attainment emotions. Furthermore, EFL learners’ performance-avoidance goals were significantly negatively associated with their positive attainment emotions, and positively related to their negative attainment emotions. Additionally, EFL learners’ mastery-approach, performance-approach, and performance-avoidance goals were significant predictors of all attainment emotions, while EFL learners’ mastery-avoidance goal was a significant predictor of their hope, anger, and hopelessness. Besides, EFL learners’ achievement goals significantly correlated with their academic success. Finally, all achievement goals predicted students’ academic success, and also mastery-approach goal was the strongest predictor of students’ academic success. The results can benefit EFL teachers, and learners to grasp a better picture of the association between achievement goals and attainment emotions, and academic success of EFL students in the context of Iran.
