The current study was designed to explore the effects of synchronous computer-mediated communication (SCMC) and asynchronous computer-mediated communication (ACMC) course modules delivered through social media networks (SMN) on the development of the Iranian L2 learners‘ comprehension of implicatures. The participants of the study were 90 English-as-aforeign-language (EFL) undergraduate students attending three intact classes. The classes were randomly assigned to one control and two experimental (SCMC and ACMC) groups. An openended implicature comprehension test was used to assess students‘ ILP development in this pretest-posttest comparison-group study. The control group received the traditional teacherfronted instruction, and the S/ACMC groups received instruction via synchronous and asynchronous modules of SMNs for 4 months, respectively. Students‘ attitudes towards the CMC-based courses were also sought. Split-plot ANOVA results indicated that both experimental groups developed significant ILP ability to comprehend and interpret L2 implicatures after the instruction; however, by comparison, the ACMC group improved more considerably. It is concluded that, first, comprehending L2 implicatures is not impervious to computer-mediated instruction and, second, different CMC affordances may result in differential ILP developmental effects in teaching L2 pragmatics. The findings can help L2 teachers decide how to use CMC affordances and SMN modules to raise L2 learners‘ pragmatic awareness.","PeriodicalId":179721,"journal":{"name":"Iranian Journal of Applied Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117268616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data of the study included interviews with 22 English teachers and 92 diary journals kept by 12 teachers who were among the top 20% of ELTEI (ELT teacher efficacy instrument) scorers and identified as efficacious English teachers. The results indicated that teachers’ goals for regulating their positive emotions included maintaining authority in relation to students, presenting unbiased teacher character, and enhancing teaching effectiveness. For regulating negative emotions, the goals included maintaining the teacher and students’ mental health, promoting teacher-student relationships, and reinforcing the image of teachers as moral guides. Teachers also used a variety of antecedent-focused and response-focused strategies hierarchically for effective emotion management including situation selection, situation modification, attention deployment, cognitive change, and response modulation. The findings were discussed with reference to the role of culture in emotion regulation and effectiveness of different sub-strategies. The results may promise some implications for teacher education programs and teacher educators about the inclusion of professional development opportunities for EFL teachers in terms of effective emotion management.","PeriodicalId":179721,"journal":{"name":"Iranian Journal of Applied Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115542647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, the university homepages have increasingly turned into the rhetorical space for the development of promotional academic texts in recent years. In this study, we examined university overview genre that provides the visitors with brief presentation of the simple facts while endorsing a specific perspective of the university and strengthening its position in the academic community. The corpus comprised 70 overviews extracted from the academic websites of the first top 500 universities. We analyzed and coded the texts to specify their overall rhetorical framework, functional moves and constituting steps, and optimal order of moves. The findings indicated that overview genre incorporates six obligatory moves including 'source of reputation', 'historical origin', 'current status of development', 'commitments, goals and orientations', 'global state', and 'services and supports'. Also, the results demonstrated that the academic genre did not follow a single, invariant pattern of sequenced moves in a clearly linear order. The findings further suggest that the nature of overview genre could be characterized by its twofold informative and persuasive functions. Finally, implications of the findings of the study are presented.","PeriodicalId":179721,"journal":{"name":"Iranian Journal of Applied Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123107707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have indicated that media discourse contributes to public opinion and ideology. Little, however, has been mentioned on how variation in media discourse affects the process. This study analyzed 24 news reports from the two countries from 24 to 31 September 2015 using the components of Systemic Functional Linguistics (SFL) and Critical Discourse Analysis (CDA). The results indicate differences in the reports from the two countries in using variation patterns which in turn have the potential of changing and monitoring readers` ideologies through influencing their opinions on the nature of power relations and interactional structures. The paper tries to contribute to the area of research on media discourse and ideology construction by arguing that discourse variation has not been sufficiently theorized.

The necessary data were collected through a series of instruments and both quantitative (e.g., multiple regression and t-tests) and qualitative (e.g., narrative construction and qualitative comparative analysis) techniques were used to analyze the data. The results of these analyses indicated that the construct of foreign language aptitude had the highest level of correlation and contributory potential to account for the writing competence of the learners. The composing process of learners with different individual characteristics was also compared and it was found that learners with high self-regulation capacity orchestrated and managed their composing behavior in more effective ways compared to their less self-regulated counterparts. Moreover, the narratives and qualitative comparative analysis provided some insights about how various individual characteristics might affect the composing behavior of the individual learners. Finally, it was suggested that consideration of individual differences in writing can reveal more subtle information about the causes of strengths and weaknesses of different learners and may enable the teachers to design and implement more effective instructions targeting their learners‟ individual needs.","PeriodicalId":179721,"journal":{"name":"Iranian Journal of Applied Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123846014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little, if any, research has been conducted on comparing types of linguistic errors treated by teachers through CF. To bridge this gap, this study sought to investigate the linguistic errors addressed and the types of CF provided by teachers. To this end, the classes of 40 teachers teaching at the intermediate level were audio-recorded for two successive sessions. The detailed analysis of around 128 hours of classroom interactions showed that explicit correction was the most frequent CF type, accounting for 48.5 percent of all CF types provided, and recast was the second most frequently used CF type, constituting 29.5 percent of all CF types. All the other CF types (i.e. request for clarification, confirmation check, repetition, metalinguistic feedback, elicitation, and multiple feedback) constituted 22 percent of the CF. Repetition was the least frequently used CF type, amounting to 0.66 percent of the CF given by teachers. As to the linguistic focus of CF, pronunciation errors were found to be the mostly noticed target for teachers‟ CF, constituting 47 percent of all errors addressed, while vocabulary was the least frequently addressed linguistic target, accounting for 17.5 percent of all errors. The study suggests that teachers prefer explicit corrective strategies over implicit ones and that they provide CF mainly to correct pronunciations errors. The study suggests that there is a need for change in the types of CF teachers use and the relative attention they assign to different linguistic error types they treat through CF.","PeriodicalId":179721,"journal":{"name":"Iranian Journal of Applied Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117256093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, metacognition has been conceptualized not only at the individual level but also at pair and group levels. The concept of socially-shared metacognition has arisen based on the idea that group members observe, control, evaluate, and regulate each other’s actions to promote the group’s problem-solving. This article investigated the impact of motivational scaffolds on a group of Iranian EFL learners’ individual and socially-shared metacognition. Two groups of 30 female intermediate learners participated in this study. In the experimental group, the participants received the teacher’s motivational scaffolds as she provided instructions and feedback throughout individual and collaborative oral and written tasks. On the other hand, the participants in the control group were asked to take part in the routine oral and written classroom activities. The participants’ think-aloud protocols in individual and pair activities were analyzed, and instances of metacognitive activities were identified. The data were analyzed through two Mann-Whitney U tests, and the results indicated that motivational scaffolds statistically significantly enhanced the use of metacognitive strategies at both inter and intra-individual levels. Implications for classrooms are discussed.","PeriodicalId":179721,"journal":{"name":"Iranian Journal of Applied Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120899561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, regarding the visual mode, research has mainly focused on superficial analyses of how often each gender appears in different roles rather than on how the two genders are represented. The tools proposed in Kress and van Leeuwen‟s (2006) social semiotics framework, however, permit deep analysis of images taking into consideration how pictorial elements are shown both alone and in relation to other pictorial elements, on the one hand, and the viewers on the other. Following the above-mentioned framework, the present study applied the three dimensions of representational, compositional and interactive meaning presented to 16 photographs randomly selected from the Interchange (Third Edition) series (Richards, 2005) to explore gender portrayals and disclose ideologies in the visual mode of the series. Qualitative data analysis showed some ideologies and stereotypical portrayals, each of which appeared either in one or a few photographs.

Moreover, the potential of literature as a means of introducing learners into the social practices and norms of the target culture, which underlie the pragmatic competence, has not been fully explored. This study, then, set out to investigate the possible contribution of plays , as a medium of instruction, to the pragmatic development through either explicit or implicit mode of instruction. To this end, 80 English-major university students were assigned to four experimental groups: two literary and two nonliterary groups. One of the literary groups (Implicit Play) received typographically enhanced plays containing the speech acts of apology, request, and refusal and the other (Explicit Play) received the same treatment in addition to the metapragmatic instruction on the acts. The medium of instruction for the nonliterary groups were dialogs containing the given functions; they were also given either enhanced input (Implicit Dialog) or input plus metapragmatic information (Explicit Dialog).

It was rather the mode of instruction that mattered most, where explicit groups outperformed their implicit counterparts.
