A critical component of cognitive diagnostic models (CDMs) is a Q-matrix that stipulates associations between items of a test and their required attributes. The present study aims to develop and empirically validate a Q-matrix for the listening comprehension section of the International English Language Testing System (IELTS). To this end, a listening comprehension test of the IELTS was administered to 820 Iranian test takers. According to theories, taxonomies, and models of second/foreign language (L2) listening comprehension, previous studies on the utility of CDMs to L2 listening comprehension, detailed content analysis of the test items, and consultation with several content experts, an initial Q-matrix was first developed. Through the technique suggested by de la Torre and Chiu (2016), along with checking heatmap plots and mesa plots using the GDINA package in R, the Q-matrix was then empirically validated. Generally, six attributes were extracted for the listening section, namely, (1) Linguistic knowledge (LKA), (2) understanding prosodic patterns (UPP), (3) ability to understand and make paraphrases (PAR), (4) ability to understand specific factual information such as names, numbers, and so forth (UFI), (5) ability to understand explicit information (UEI), and (6) ability to make inference (INF). Finally, the results of the fit of the GDINA model to the data, at both item and test levels, indicated the adequate model-data fit and the plausibility of the Q-matrix. The implications of the study were also discussed.

Intercultural communication is a widespread matter in today’s world with the advent of globalization and social media. Thus, this study focused on exploring the role of cultural knowledge and linguistic knowledge in the formation of intercultural competence. The researchers selected 150 Iranian learners through a purposeful sampling procedure in a qualitative design. By using interviews, observation, and reflective journals the required data was collected. The researchers used inductive analysis and thematic analysis to analyze the collected data. The results revealed that cultural knowledge and linguistic knowledge are both equally important in the formation of intercultural competence of Iranian learners. Also, it is shown that Iranian learners make use of both linguistic knowledge and cultural knowledge to have effective communication, build trust and rapport, conflict resolution, and avoid linguistic and cultural misunderstandings. This study is important for language teachers, book writers, and curriculum developers in that they should pay more attention to both linguistic knowledge and cultural knowledge in their teaching, book writing, and curriculum development respectively.

Motivation and affect as two salient variables in L2 development are no longer seen as the stable individual difference factors they were once believed to be. Influenced by process-oriented approaches and by increasing understanding of how the complex dynamic system theory (CDST) works, researchers have been emphasizing the holistic, non-modular, dynamic and changeable nature of motivation and affect to-date. Accordingly, this study utilized the principles underlying the CDST perspective to examine the interrelationships between Iranian EFL learners’ motivational and affective factors mediated by working memory and gender over an academic semester. To this end, 445 pre-intermediate male and female students completed the motivation questionnaire and L2 Enjoyment Scale four times with one-month intervals during an academic semester and Working Memory Scale once in the beginning of the term. Relationships that emerged indicated both motivational and affective stability and fluctuation over a semester of instruction at one month intervals. The findings also illustrated how these factors are inseparable from students’ learning context. Implications of study and directions for further research were also discussed.

Construct-irrelevant variance is considered as a major threat to validity which indicates the existence of additional unrelated variables that distort the meaning of test scores and cause the test to be biased. Differential item functioning (DIF) analysis is an important technique in examining the validity and fairness of educational tests. Concerning the importance of test fairness in large-scale exams, this study aimed to (1) detect gender DIF in the reading comprehension section of the B2 First exam using the Rasch model and Mantel-Haenszel method, and (2) investigate the comparability of results from the two DIF detection techniques. To this end, the reading section of the B2 First exam was administered to 207 undergraduate students of English as a foreign language (EFL). After checking the fit of the data to the Rasch model, the results of the Rasch model-based DIF analysis showed the presence of two items indicating DIF, whereas the results of Mantel-Haenszel showed that there were three gender-DIF items.

Computer-Mediated Communication (CMC) modes can ease scaffolding through multimodality in collaborative writing tasks. However, there is an ongoing debate regarding synchronous and asynchronous CMC environments. Additionally, there are conflicting results regarding gender’s pedagogical beliefs in CMC applications. The current study aimed to explore if there is a difference between synchronous and asynchronous multimodal scaffolding on the freewriting complexity of EFL learners. Besides, genders’ perceptions about applying multimodal scaffolding were compared. Participants were 84 EFL learners who randomly assigned into three groups. For the pre-test, a picture, podcast, and movie were shared, and the participants were asked to complete their freewriting tasks individually within the allocated time. For treatment, one experimental group was scaffolded in a synchronous environment by sending messages on WhatsApp, and the other experimental group experienced asynchronous scaffolding via email. The results indicated that multimodal scaffolding is beneficial. However, no significant difference was found between the writing complexity of synchronous and asynchronous groups. Furthermore, a significant difference between males’ and females’ tendency to use multimodal scaffolding was uncovered. The findings highlighted the role synchronous and asynchronous multimodal scaffolding can play in collaborative writing tasks
