This study compared the efficacy of explicit and implicit instruction of requestive strategies on upper-intermediate female English as a foreign language (EFL) learners’ email writing development. Sixty-two participants in four intact classes were randomly assigned to two explicit and implicit groups. In this quasi-experimental pretest-posttest design study two email evaluation tests and two written discourse completion tests (WDCT) were used to collect the data. In the pretest phase, an email evaluation test and a WDCT were administered to the participants in two sessions. Next, the two groups were provided with ten treatment sessions. The explicit group received direct instruction and metapragmatic explanation on the use of appropriate requestive strategies in writing emails. The implicit group, however, received instruction on writing requestive emails without any explicit explanation about the requestive strategies in emailing. Then, the participants took the posttest of email evaluation test and WDCT in two successive sessions. The results indicated that both modes of instruction exerted significant effects on the learners’ production of requestive strategies in English. The comparison of the two modes of instruction, nonetheless, indicated that the participants who underwent explicit instruction significantly surpassed those in the implicit group. The findings have implications for materials developers and instructors.

A narrative monologue skill is required in learning English. Delivering a monologue is a challenging skill for most of the EFL students since it is difficult for them to utilize their lexical and grammatical knowledge. This study investigates the effects of narrative sequential images on the Iranian intermediate EFL students’ monologue skill. To this end, the study was conducted in two intact classes (one as the experimental group and the other as the control group) of 32 students within 2 months in a high school in Isfahan. To select homogenous participants, Oxford Placement Test and Oral Proficiency Interview were administered. A monologue pre-test was used at the beginning of the study. And the specific treatment was administered to the experimental group. Then, a parallel post-test was conducted. Based on the results, there was a significant difference in the scores of the experimental group in all aspects of fluency, coherence, lexical resources, grammar and accuracy, and pronunciation in using narrative sequential images before and after treatment. In other words, experimental group performed better on the four subscales of monologue skill than did the control group. Results, also, suggested that teachers use sequential images as a part of their instruction to help students develop their monologue skill.

Much of what educators address is the overt curriculum; however, there is a hidden curriculum that affects education in a very profound manner. In view of that, the purpose of the present study is to determine the relationship of EFL teachers’ perspectives on hidden curriculum components in the Iranian institutional context with their students’ self-efficacy and national identity. More specifically, the present study surveyed the probable existence of any significant correlation between EFL teachers’ perspectives on the EFL hidden curriculum components, their students’ attitudes towards their own national identity, and self-efficacy. For this purpose, a model was suggested and tested using partial least squares variance-based structural equation modeling (PLS-SEM), to examine EFL teachers’ perspectives on the EFL hidden curriculum components contributing to their students’ national identity and self-efficacy. A total of 164 institutional EFL teachers in Iran completed the EFL hidden curriculum questionnaire. Besides, 987 students (about eighty percent of their learners) were asked to fill in national identity and self-efficacy questionnaires. Based on this model, all the correlations between the latent variables were significant except for three latent variables including the relationships among EFL teachers’ perspectives on the EFL hidden curriculum components (social atmosphere, organizational structure, and interaction between teachers and learners) and their learners’ self-efficacy. In addition, the results depicted all the relationships between latent variables was positive relations; while, the relationship between EFL learners’ national identity and self-efficacy was proved to be negative.

Code-switching (CS), an alternation between two or more languages or language varieties, has long been researched in language education. A great number of studies by applied linguists have explored the reasons for, and the potential usages of code-switching in foreign language education over the past years. This study explores the perceptions of English language learners across various proficiency levels concerning teachers’ use of CS, in this case Farsi in English classrooms. It also examines the roles and functions of CS in the classroom. Fifty teachers and 105 language learners from University of Tehran Language Center (UTLC) in Tehran, Iran were involved in this study. The necessary data were obtained through questionnaires. The results suggested that the Elementary (EL) learners seem to benefit from the teachers' use of first language in class, whereas English-only classroom is preferred by Intermediate (IN) and Upper Intermediate (UI) ones. It was also revealed that maximum exposure of the learners to the target language seems necessary. The results suggest that, concerning the learners' levels (EL, IN and UI), teachers’ and learners’ Code Switching can work as a useful language teaching strategy. The findings of this study can have implications for English as a Foreign Language (EFL) classrooms and can be used by language teachers.

This study was designed to explore the relation pattern of cultural intelligence, cultural identity, autonomy, and self-efficacy and second language achievement of Iranian EFL learners. The participants were 247 undergraduate students. Data were collected nationwide, from different parts of Iran; that is, from Kerman, south of Iran; Hamadan, west of Iran; Mashhad, east of Iran; and Gorgon, north of Iran. The participants' ages ranged from 18 to 26 and they were mostly juniors and seniors. They completed the following questionnaires: Cultural Intelligence Questionnaire (Ang, et al., 2007), Cultural Identity Clarity Scale (Usborne & Taylor, 2010), Learner Autonomy Questionnaire (Cotterall, 1995, 1999) and Self-Efficacy Questionnaire (Pinitrich, Smith, Garcia & Mckeachie, 1991). The participants’ GPA of three general English courses were considered as their second language achievement. Responses from questionnaires were collected through convenience sampling. The design of the study is based on path analysis. After data collection, the hypothesized model was tested by AMOSE program. The results demonstrated that the variables under study could strongly predict EFL learners' L2 achievement. L2 achievement may largely depend on students’ cultural intelligence, cultural identity, autonomy and self-efficacy. Also, it was reported that autonomy was the strongest predictor of EFL learners’ L2 achievement.

This study focuses on complexity matching and lexical matching to investigate speech convergence in the conversations of bilingual Persian-English speakers in three language conditions namely Persian, English, and mixed in the context of lingua receptiva as an attempt to investigate such matching mechanisms between a Latin-based language and a non-Latin-based language. Complexity matching investigates convergence in terms of the hierarchical temporal structure of human speech while lexical matching explores convergence in terms of the frequency occurrence of the matched lemmas. For this purpose, 14 master’s students from the Shahid Chamran University of Ahvaz majoring in English language conversed with one another in dyadic groups in three language conditions each of which had its own topic namely movies, music, and books. In complexity matching, Allan Factor analysis in terms of multiscale clustering of onset events was considered. In lexical matching, the focus was on the distribution of all lemmas and matched lemmas and the possible correlation between the two. The results revealed a gradual increase in Allan Factor log-log plots in relation to the longer timescales that correspond with discourse patterns for complexity matching. For lexical matching, the positive correlation between all lemmas and matched lemmas (r<sub>s = .607) suggested that as participants talked to each other more, they unconsciously tried to match their psychological perceptions with each other more. This suggests that speech convergence is vigorous in both bilingual and monolingual interactions.

: This study investigated the impact of audio-visual input enhancement teaching techniques on improving English as Foreign Language (EFL) learnersˈ collocation learning as well as their accuracy concerning collocation use in narrative writing. In addition, it compared the impact and efficiency of audio-visual input enhancement in two learning contexts, namely traditional and mobile learning contexts. First, 120 homogenous intermediate EFL learners were randomly divided into four groups, two experimental and two comparison groups. Next, two pre-tests, a collocation and a paragraph writing test, were administered. The experimental groups received enhanced target collocations through input enhancement teaching techniques while in the comparison groups the “unenhanced” collocations were taught through conventional simple vocabulary teaching method. After the treatment sessions, the researcher administered two post-tests including a collocation and a paragraph writing. As the data analysis suggested, with regards to the first research purpose, audio-visual input enhancement positively affected EFL learners' collocation learning and enhanced their accuracy concerning collocation use in narrative writing. Regarding the second purpose of the study, the results revealed that, in comparison to traditional learning context, audio-visual input enhancement teaching techniques were significantly effective in mobile learning context in terms of collocation learning. The efficiency of audio-visual input enhancement teaching techniques was not significantly different between the experimental groups in the two learning contexts in terms of enhancing EFL learners’ accuracy concerning collocation use. The findings of this study can create awareness for second language teachers and learners about the critical and beneficial role of input enhancement and mobile assisted language learning in successful language acquisition and learning.

Writing a book review is an instance of evaluative academic writing where the writer is involved in an interaction with the author and the reader, evaluates the viewpoints stated in the book and voices his own position and stance in a dialogue with the reader. Working within the framework of Martin and White’s (2005) Appraisal Theory as an effective tool for studying the essential resources employed in this interaction and evaluation, the present study examined 60 book reviews from the Humanities academic journals written by native male and female writers, and tried to investigate the type and frequency of the three Appraisal categories (Attitude, Engagement, Graduation). The findings indicate that both writer groups made extensive use of these resources in their writings. However, the male book review writers exceeded the female writers in all the three categories. In addition, the Attitude resources were used the most and The Engagement resources were the least employed resources. The implications of the study for teaching writing skills and developing materials and tasks for writing courses at academic levels are mentioned in detail
