Perhaps the degree of test difficulty is one of the most significant characteristics of a test. However, no empirical research on the difficulty of the MSRT test has been carried out. The current study attempts to fill the gap by utilizing a two-parameter item response model to investigate the psychometric properties (item difficulty and item discrimination) of the MSRT test. The Test Information Function (TIF) was also figured out to estimate how well the test at what range of ability distinguishes respondents. To this end, 328 graduate students (39.9% men and 60.1% women) were selected randomly from three universities in Isfahan. A version of MSRT English proficiency test was administered to the participants. The results supported the unidimensionality of the components of MSRT test. Analysis of difficulty and discrimination indices of the total test revealed that 14% of the test items were either easy / very easy, 38% were medium, and 48% were either difficult or very difficult. In addition, 14% of the total items were classified as nonfunctioning. They discriminated negatively or did not discriminate at all. 7% of the total items discriminated poorly, 17% discriminated moderately, and 62% discriminated either highly or perfectly, however they differentiated between high-ability and higher-ability test takers. Thus, 38% of the items displayed satisfactory difficulty. Too easy (14%) and too difficult (48%) items could be one potential reason why some items have low discriminating power. An auxiliary inspection of items by the MSRT test developers is indispensable.

This study compares three integrated tasks of the TOEFL iBT speaking subtest in terms of complexity, accuracy, and fluency. To this end, a group of TOEFL iBT Iranian candidates took a simulated TOEFL iBT some days prior to their real exam. The collected oral responses were first transcribed and then quantified using software such as ‘Syllable Counter’ and ‘Coh-Metrix3’ for fluency and complexity, respectively. For accuracy, however, the responses were tallied manually. The results revealed the responses to the three speaking tasks were significantly different in terms of fluency. The difference in the accuracy index also turned significant, though the pairwise comparisons showed some inconsistencies. As for the selected complexity measures, lexical diversity, the mean number of modifiers per NP, and latent semantic analysis all showed significant differences between tasks 2 and 3 on the one hand and task 4 on the other. Left-embeddedness, however, revealed no significant difference among the three tasks. The results may support the influential role of prompting texts in such integrated speaking tasks

Collaborative dialogue (CD) in developing L2 skills known as ‘knowledge-building dialogue’, in spite of its momentum in foreign language acquisition, has rarely been conjoined and empirically investigated with a Task-based approach. To this end, the present research was conducted with a two-fold aim: firstly, investigating the effect of task-based collaborative dialogue on English as a foreign language (EFL) learners’ speaking ability, and secondly, exploring teachers’ and learners’ perceptions of the exercised treatment process. The participants of the study consisted of 100 Iranian B.A. TEFL and Translation Studies students were identified as relatively homogeneous with regard to their language proficiency through administering Oxford Placement Test (OPT) and ten Iranian EFL teachers. The experimental group was exposed to task-based collaborative dialogues, while the control group experienced conventional mainstream teaching the speaking skill. Upon completing the treatment, CD questionnaires were administered to the experimental group of learners and teachers to investigate their perceptions of implementing CDs in speaking classes. Subsequently, the teachers and 12 students from the experimental group attended the semi-structured interview sessions to explore their views regarding the efficiency of task-based CDs. The findings indicated that the experimental group outperformed the control one regarding speaking skill. The results of the questionnaires and the semi-structured interviews complemented each other and indicated that the teachers and the learners adopted positive views toward applying the task-based CD. The findings offer some implications for the stakeholders, including material developers, EFL learners, and teachers, to incorporate task-based collaborative dialogues in second language education.

This study intended to compare the effects of prescriptive and collaborative models of observation on EFL teachers’ perception of their self-efficacy. From among 80 participants, 40 teachers, including 20 novice and 20 experienced teachers, were randomly assigned to the collaborative observation group (experimental group) and another group of 40 teachers, which comprised of 20 novice and 20 experienced teachers, were randomly assigned to the prescriptive observation group (control group). A sequential explanatory design was employed so that both quantitative and qualitative data collection/analysis procedures could be employed. The quantitative data were collected through The Ohio State Teacher Efficacy Scale (OSTES) (Tschannen-Moran & Hoy, 2001), and the qualitative data were elicited through semi-structured interviews. The results of both quantitative and qualitative data revealed (i) the significant difference between prescriptive and collaborative observation in terms of teachers’ perception of their self-efficacy, and that (ii) in the collaborative observation group, there was a significant difference between novice and experienced teachers’ perception of their self-efficacy. The study has implications for both teachers and teacher educators, suggesting that collaborative observation could enhance EFL teacher development.              

Standard political discourse is replete with ambiguity and vagueness. Politicians frequently use vague language to hide their inadequate knowledge, show their low interest in the issue, and/or evoke emotion. This study reports on a qualitative content analysis of vagueness in two Iranian presidents' political interviews within a pragmalinguistic and sociopolitical paradigm. The data consisted of nine question-answer exchanges extracted from seven internationally live broadcast interviews. A total of 57 instances of vague language use were analyzed in terms of 21 pragmalinguistic vagueness strategies. Implications are that vagueness in political discourse is motivated by a multiplicity of factors such as face management, sociopolitical and situational adaptation, conflict avoidance, and personal characteristics of the interviewers and the respondents. Vagueness was also found to be a sign of diplomatic prudence or wisdom.

This research study was conducted to investigate the most representative characteristics of the habitus developed by academically successful Iranian English majors. Learning a second or foreign language, like many sociocultural practices, from a Bourdieusian perspective, is informed by the interrelation between habitus, field, and cultural capital (CC). Within an exploratory qualitative design, utilizing the Biographical Narrative Interpretive Method of both semi-structured and unstructured one-on-one interviews, seven academically successful BA students majoring in English language studies were studied in an attempt to explore their CC and habitus. Each participant was interviewed in 3 separate sessions. The constructivist grounded theory method was adopted to analyze the collected data. Constructed on 75 initial codes, 22 focused codes, 10 categories, and 4 themes, two major themes were most relevantly indicative of theoretical associations with the research problem. The findings suggest that the habitus developed by the English majors in this study was representative of their accumulation of certain forms of CC. Their habitus seemed to have been developed under the influence of their interaction with the mediatory field of learning and majoring in a foreign language. In an exigency-driven social quest for certain forms of cultural capital, the participants’ habitus were majorly characterized and influenced by their strategic accumulation of institutional and social capital, their field-oriented social identities, and their strategic administration of CC in the field. The knowledge developed by the findings of this study can provide useful sociocultural insights into academic achievements of English language majors.
