From the dawn of the third millennium, the utilization of state-of-the-art technology for educational purposes, especially computers and the Internet, has become prevalent across the globe. In this regard, flipping EFL classes appears to be an effective approach to practicing second/foreign languages through computer-assisted language learning (CALL) in order to extend the class time to asynchronous activities outside the class, and make the students more autonomous and actively engaged in the painstaking process of language learning. However, this question merits consideration why many current CALL programs run and taught through flipped learning do not seem to take full advantage of collaborative learning and peer-assessment, specifically taking place in asynchronous channels of communication, namely threaded comment forms and discussion boards. The present study investigates the prospect of realizing social presence as a shared feeling of community among the learners by restructuring and optimizing the existing methods for flipping language classes. Employing a qualitative research based on grounded theory and data triangulation, the researchers recorded, transcribed and analyzed 41 semi-structured group and individual interviews with 44 participants attending an online IELTS preparation course on the first researcher’s website for over one year. Additionally, the same interview questions were posed in an open-ended questionnaire accessible to the participants from the website. The obtained results suggested that learner-centered flipped classes in which asynchronous student-driven content development and out-of-class peer-assessment through commenting and replying are adequately practiced can tremendously increase student interactivity, thereby fulfilling the sense of social presence.

L2/FL writing ability, which per se includes many different types, is considered a major skill in academic settings. However, little research has been done in this area and even less has focused on the effectiveness of task-based writing instruction on the two specific kinds; namely, referential writing and expressive writing. To this end, 60 English Translation sophomores of both genders were selected and divided into two classes after ensuring their homogeneity through the Quick Placement Test (OQPT). For the pre- and post-tests, the participants were required to take IELTS writing tests requiring referential and expressive types of writing. As for the treatment of the study, all participants were instructed based on the same content materials of advanced writing and a task-based framework. The results of the statistical analysis indicated significant improvements in the participants’ writing abilities in referential and expressive written tasks. Besides, the effectiveness of task-based writing techniques was approved in terms of referential and expressive types of language functions in the academic writing of Iranian EFL learners.

Investigating the processes underlying test performance is a major source of data for supporting the explanation inference in the validity argument (Chappelle, 2021). One way of modeling the cognitive processes underlying test performance is through the construction of a Q-matrix, which is essentially about summarizing the attributes explaining test takers’ response behavior. The current study documents the construction and validation of a Q-matrix for a high stakes test of reading within a generalized-deterministic inputs, noisy “and” gate (G-DINA) model framework. To this end, the attributes underlying the 20 items of the reading comprehension test were specified through retrospective verbal reports and domain experts’ Delphi techniques. In the ensuing stage, the Q-matrix thus developed along with item response data of 2625 test-takers were subjected to empirical analysis using the procedure suggested by de la Torre and Chiu (2016). Item-level results showed that, except for one item, the processes underlying the other items were captured by compensatory and additive models. This finding has significant implications for model selection for DCM practitioners.

The aim of this research was to investigate the effectiveness of mental imagery on the English language comprehension of sixth grade students. The method is semi-experimental and its plan involves pretest, post-test, and follow-up. Using a multi-stage random sampling method, 32 students were selected from schools in the district (2) and assigned to either the experimental or evidence group - each group consisted of 16 students. All the students within both groups were given a pretest which consisted of 20 multiple choice questions (with 4 possible answers each). There was no significant difference between the mean scores gained by the students of both groups on the pretest. The experimental group received the mental imagery teaching program and how to form pictures in the mind-e.g, how to visualize-before reading, while reading, and after reading a short story, for example, by being requested to draw pictures of the characters, scenes, or setting in the story as they perceived them. The evidence group received no instruction. To measure the effectiveness of the treatment program for each experimental condition, a research-made reading comprehension test was applied. There were  significant differences between the experimental and evidence groups, when data analysis was performed by ANOVA, using repeated measures. The findings showed that the mental imagery teaching program can improve the English language comprehension and this study suggests that the English teacher may improve her teaching strategy by optimizing the use of a variation technique in school. The teacher should be creative while delivering materials in the class.
