The focus of the present study was to explore the effect of self-directed learning method on Iranian EFL students’ writing achievement in two levels of language proficiency (pre-intermediate and intermediate). It also attempted to find out if there was any significant difference between two groups of learners, control and experimental, in each level regarding their development of writing skill. In order to reach this goal, 30 male EFL learners that were selected based on random sampling, participated in this study. After the treatment was over, both groups in each level were given the post-test, the results of which were compared with pre-test results. Then, an independent sample t -test was run to find the effectiveness of two approaches to detect the differences among the means of the two groups in each level. The results of the present research indicated that the self-directed learning method had significant effects on the pre-intermediate and intermediate students’ performance of English writing ability. The results also indicated that there was a significant difference between the two groups of learners in each level regarding their development of English writing ability.

Practical improvements in students’ overall success can be made if we take into account the contribution of learning environments to learners’ various attributes that would greatly affect their academic selves. This study aimed at scrutinizing the possible associations among Iranian EFL students’ perceived classroom climate, academic self-concept, learning self-regulation, and academic identity status. 420 university students were asked to fill out College and University Classroom Environment Inventory (CUCEI), Academic Self-Concept (ASC) Scale, Learning Self-Regulation Questionnaire (SRQ-L), and Academic Identity Status (AIS) Questionnaire. Using Structural Equation Modeling (SEM) and based on its several goodness-of-fit criteria, the proposed model of the possible interactions of the main variables was confirmed. Furthermore, classroom climate was correlated positively with subscales of learning self-regulation and academic self-concept and negatively with academic identity status. Besides significant correlations among study variables, the final model also revealed some intra-scales associations. Multiple regression analysis also indicated some significant predictions. The findings could provide classroom instructors and university syllabus designers with implications so that they can plan the EFL environments and class activities taking into consideration students’ various academic characteristics. This involves their status of self-concept, identity, and regulation to help them achieve highly recognized long-term academic objectives.

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.
