Psychophysiological studies and MRI neuro-imaging findings provide evidence that heart rate variability (HRV) which is in control of our emotions affects our brain cognitive centers. It has been shown that coherent heart-brain interaction can change the pattern of the afferent cardiac input that is sent to the brain. For this purpose, the Institute of HeartMath (IHM) has proposed a kind of biofeedback training, the TestEdge program, which self-regulates negative emotional learning impediments by increasing HRV measures. It leads to an optimal self-generated psychophysiological state that has an important role in cognitive development through autonomic nervous system dynamics. In the present study, through using IHM self-regulated techniques and tools, the TestEdge program was performed on 63 Iranian EFL learners. In particular, the main purpose of this study was to investigate the effects of HRV measures on reading comprehension performance. The data was measured and recorded by emWave Desktop device. The results confirmed that the intentional heart-focus techniques led to a beneficial mode of psychophysiological coherence of heart-brain interaction. The results indicated significant differences among EFL students with different levels of high, mid, and low coherence and their reading performance.

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.

Whether acknowledged or neglected by educators, the hidden curriculum is present in every institute. Therefore, studying the hidden curriculum is essential to understand how it functions within an English language institute’s setting and among those within it. The purpose of this study was to design and validate a scale to measure language teachers’ perspectives on English as a Foreign Language (EFL) hidden curriculum by the application of the Rasch model. The review of the literature indicated the lack of sufficient research on the investigation of EFL hidden curriculum components in the view of EFL teachers. To fill the existing gap in the literature, a 40-item questionnaire was devised and validated, then 164 Iranian EFL teachers, teaching at different language institutes were asked to reply to the questionnaire. In this study, hidden curriculum components were based on Saylor, Alexander, and Lewis’ (1981) perspectives. Accordingly, items were classified into three different constructs, namely the social atmosphere (including 15 items), the organizational structure of the English Language Institute (consisting of 14 items), and the interaction between teachers and learners (including 11 items). The results showed that the questionnaire items fitted the Rasch model after removing six items from the scale. Moreover, it was confirmed that the scale enjoyed suitable reliability. This proposes that the questionnaire is potentially valid and can be used as a measure of EFL hidden curriculum. One of the study implications is that the questionnaire designed and validated in this study can be used as a research tool in future research to assist policymakers and material designers, institutions’ administrators, and language teachers to be considered for future decision making, and designing materials. It also can be used as a research tool to measure the relationship between EFL hidden curriculum and other variables in future research.

Interlanguage pragmatics has attracted considerable attention in recent years. One strand of interlanguage pragmatics research includes studies comparing the effectiveness of implicit versus explicit teaching on the development of pragmatics. Many studies, although inconclusively, have shown the superior effect of explicit teaching of pragmatics, but few have focused on finding ways to improve the implicit teaching of pragmatics. The present study attempted to unfold the effect of collaborative dialogue on the quality of implicit teaching of request (head act and preparator). To this end, 28 participants (19 to 33 years old, intermediate) majoring in English (freshman and junior) were divided into two groups. The experimental group (n=14) had the opportunity to complete the tasks collaboratively and the control group (n=14) were not provided with any specific pragmatic instruction. The instructional procedure included four successive sessions of teaching request in situations where the sociological parameters were systematically varied. For the purpose of data collection, the classes were audio-recorded and a pretest-posttest design for discourse completion task (DCT) was adopted. For the purpose of data analysis, target request head acts and preparators were scored and also the audio recordings of classes were transcribed and the process of learning during treatment was checked in detail. The findings indicated that the experimental group outperformed the control group in producing target preparators and head acts. And evidence of noticing the pragmatic forms namely noticing unnoticed forms, noticing the gap, and negotiation of form was observed during the collaborative task. This study suggests that teachers may need to provide learners with the opportunities for collaborative tasks along with input enhancement tasks in order to improve the pragmatic knowledge of the learners.

This study investigated the receptive and productive vocabulary command of learners based on their willingness to communicate (WTC) and critical thinking skill. The study also aimed to compare gifted and non-gifted learners in terms of the above-mentioned variables. To this end, 112 gifted and non-gifted Iranian EFL learners were picked out and given four instruments (WTC questionnaire, critical thinking skill test, receptive, and productive vocabulary tests). Having analyzed data through two-way ANOVA and independent samples t-tests, the study revealed that, first, no significant difference was found between high and low WTC learners and also high and low critical thinkers in their receptive lexical command; and second, high and low WTC learners, high and low critical thinkers, and also gifted and non-gifted learners showed significant differences in their productive lexical command. Thus, while for receptive vocabulary knowledge, giftedness is a more influential factor than WTC and critical thinking, for productive vocabulary knowledge, WTC, critical thinking, and giftedness are all influential. The pertinent theoretical and practical implications of the study will also be explicated.

The present study was conducted to further improve the practice of written corrective feedback by integrating the two known feedback types (i.e. direct corrective feedback and metalinguistic explanation). With this aim, a sample of sixty-nine high-intermediate Iranian EFL learners was assigned into different feedback groups. While the first and second groups received direct and metalinguistic explanation feedback, respectively, the third group received an integration of both. Results showed that all three types of feedback improved the learners’ accuracy, though with different degrees of success. However, the results of the delayed post-tests revealed that only the integration of Direct Corrective Feedback (DCF) with Metalinguistic Explanation (ME) had the most sustainable effect on the learners' accurate use of the articles in the long run. It is discussed that the integration of DCF and ME can enhance the corrective effect of the feedback and reduce the defects which have been associated with the practice.

This study investigated the relationship between Iranian high school students’ Universal Grammar knowledge and their performance on such standardized general English proficiency tests as PET and FCE internationally administered by Cambridge University. To this end, 108 students were randomly chosen from some high schools located in Malayer from Hamedan. Since this study was correlational in nature, and descriptive and hypothesis-testing by definition, the research participants were given no treatment. Three tests were administered to them instead. To measure UG knowledge, a researcher-made UG test was given to all participants. This test which was made both reliable and valid included pied-piping and preposition stranding principle, binding principle, pro-drop parameter, that-trace effect, projection principle, resumptive pronoun and subjacency principle. To assess the participants’ general English proficiency, PET and FCE tests were run. All participants took the three tests consecutively at two-week intervals after they were given clear and detailed instructions. The findings were manifold. Firstly, there was a significant relationship between UG knowledge and performance on the proficiency tests. Secondly, there existed no significant difference between the proficiency tests as far as the UG test was concerned. Finally, the UG test scores were, through the Cubic regression model, proved to predict the scores gained on both proficiency tests. Most importantly, this study led to some suggestions regarding the learner variables and the under-explored issue of integration of generative SLA and language testing, more specifically standardized general English proficiency tests.

To succeed in tests does not require only content knowledge. Test-taking strategies are other factors which help students to achieve high scores in tests. The present mixed-method study set out to examine the relationship between test-taking strategies and reading test performance. To achieve the objectives of the study, a reading comprehension test, and a 35-item Likert type strategy questionnaire were given to 214 male and female university students. Analysis of the gathered data revealed that there was a positive relationship between test-taking strategies and reading test performance and that successful, moderately, successful, and unsuccessful test-takers differed in their use of cognitive and metacognitive strategies. To gain an in depth view on strategy use pattern of the test-takers, retrospective interviews along with think-aloud protocols were applied which revealed the use of metacognitive test-taking strategies more than cognitive ones. These findings can have beneficial implications for language testers, teachers, learners, and course developers.
