Private speech utilization is accepted to have a critical role in the continuum of language acquisition. As a valuable device in studying learners’ talk during interaction, a language related episode (LRE) is any part of a dialogue where a student speaks about a language problem s/he comes across while completing a task. The present study investigated the role of private speech produced by Intermediate Iranian EFL learners while they were involved in completing a dictogloss. For this purpose, 12 female EFL learners were chosen and they were required to speak about a lexical item cooperatively while they were completing a dictogloss task. These interactions were recorded and their lexical language related episodes were transcribed. In order to investigate the private speech used in the interactions, data was coded for different forms and contents of private speech and their functions were identified. The results indicate that private speech is mostly used for self-regulation and gaining control over the task. The study has implications for teachers and researchers by giving insights on how L2 is used in interactions.

Motivation for learning a new language is both self and time-oriented. The language learner’s motivation experiences gradual fluctuation over time and the view of oneself is different on each timescale of the study. Interaction among different timescales throughout the Second Language Development (SLD) is a novel area of investigation (de Bot, 2015). In order to probe this interactive nature, the present study tried to examine the motivational dynamics of a group of language learners in longer timescales composed of a number of tasks performed on shorter timescales. To this end, a group of university students were surveyed at the onset, while performing tasks and at the end of the course to better picture the interplay of different motivational themes over time. The results revealed different manifestations of components of L2 Motivational Self System (L2MSS) over different timescales of the study. Apart from this evolutionary manifestation of L2MSS components, ANNOVA results revealed significant difference between scores of each individual component among all three timescales. In sum, results of the study confirmed temporal and visionary variation in participants’ motivation. Finally, some implications were driven from the findings of the study.

This paper reports on the findings of a research aimed at exploring the professional identity (PI) of English as Foreign Language (EFL) teacher in Iran. The research further examined the extent to which the identified PI factors affect their teaching quality. The authors argue that earlier classification of different factors of professional identity of EFL teachers is arbitrary and may only be valid by definition. The possible grouping of these factors is also examined to identify what clusters of factors have relative importance in EFL teacher's professional identity and how these clusters may contribute to the quality of teaching. Sample participants contributed in semi-structured interviews and subsequently based on the thematic analysis of the interviews a questionnaire was developed and completed by a total of 143 EFL instructors and students. Factor Analysis of data identified four distinct clusters accounted for a total of nineteen variables presenting the PI profile of EFL teacher in which Personal Characteristics (PC) emerged as the most important cluster. Consequently, five clusters identified to have a considerable effect on teaching quality, Pedagogical knowledge (PK) found to be the most influential cluster. These findings may well serve as a valuable pedagogical resource for EFL teachers and policy makers to help improve teaching quality, educational processes, and curriculum design.

Context is a vague notion with numerous building blocks making language test scores inferences quite convoluted. This study has made use of a model of item responding that has striven to theorize the contextual infrastructure of differential item functioning (DIF) research and help specify the sources of DIF. Two steps were taken in this research: first, to identify DIF by gender grouping via logistic regression modeling, an inventory of mostly cited DIF sources was prepared, based on which a list of demographic items was appended to the TOEFL reading paper only to be administered to the intermediate Iranian undergraduates; second, using multiple-variable matching regression (Wu & Ercikan, 2006), a built-in sequence was followed to let every potential DIF source be considered as a covariate, over and above the conditioning variable, and specify whether a particular ecological variable could reduce DIF value/status. Then, all significant variables were analyzed together to show the final DIF predictors. The same procedures, i.e., individual/collective analyses, were employed after the purification of the test. The results indicated three ecological predictors affecting DIF before and after purification: income, administration convenience, and SES. The ultimate predictors helped create an EFL configuration of the ecological model of item responding. The implications for validity arguments are also discussed.

The present study investigates the effect of different exposure densities on third grade Iranian junior high school (IJHS) students’ EFL development and retention. It also attempts to explore whether there is any differential performance due to type of post-exposure assessment tasks (recognition vs. written production). Performances of five groups of learners receiving equal amount of exposure to EFL knowledge with different densities over different time spans were compared on both recognition and written production tasks. The results of the repeated measures analysis of variance and paired sample tests reveal that there seems to be a threshold exposure density for development of structure production, as well as for the retention of total EFL and vocabulary production. Analyses of variance for the five groups were performed on the raw scores obtained for a pre-test and two post-tests. The results further reveal significant differences for acquisition and retention of the target EFL knowledge among different groups. The results also suggest different optimal exposure densities for the target EFL knowledge development and retention.
