Annually, researchers in various scientific fields publish their research results as technical reports or articles in proceedings or journals. The collocation of this type of data is used by search engines and digital libraries to search and access research publications, which usually retrieve related articles based on the query keywords instead of the article’s subjects. Consequently, accurate classification of scientific articles can increase the quality of users’ searches when seeking a scientific document in databases. The primary purpose of this paper is to provide a classification model to determine the scope of scientific articles. To this end, we proposed a model which uses the enriched contextualized knowledge of Persian articles through distributional semantics. Accordingly, identifying the specific field of each document and defining its domain by prominent enriched knowledge enhances the accuracy of scientific articles’ classification. To reach the goal, we enriched the contextualized embedding models, either ParsBERT or XLM-RoBERTa, with the latent topics to train a multilayer perceptron model. According to the experimental results, overall performance of the ParsBERT-NMF-1HT was 72.37% (macro) and 75.21% (micro) according to F-measure, with a statistical significance compared to the baseline (p<0.05).

The study aimed to examine the mediating role of self-efficacy beliefs in the relationship between coping strategies and language learning anxiety using Structural Equation Modeling (SEM). A total of 783 language learners participated in this research and completed Coping with Language Anxiety Scale, Foreign Language Anxiety Scale, and Self-Efficacy Belief Scale. The data were analyzed using SEM to test the hypothesized mediation model. Results indicated that coping strategies were negatively associated with language learning anxiety. Furthermore, self-efficacy beliefs partially mediated the relationship between coping strategies and language learning anxiety. Specifically, higher levels of self-efficacy were found to enhance the negative effect of coping strategies on language learning anxiety. These findings highlight the importance of promoting coping strategies and self-efficacy in language learning contexts to reduce anxiety. The implication of these findings for language learners, educators, and researchers are discussed, along with suggestions for future research in this area.

The breakout and intensification of the worldwide Coronavirus pandemic caused dramatic changes to education across the world. Both teachers and students were not prepared for the sudden change regarding the mode of teaching and learning: onsite to offsite and offline to online. The current study seeks to identify frequent problems that first-year English major students have during their online learning process and explore their suggestions for the improvement of the situation. Data were collected from an online survey of 89 first-year English-majored students. The students’ obstacles were identified by the 30-item questionnaire, and their suggestions for positive changes were explored thanks to open-ended questions. The results show that learning environment is the students’ biggest problem due to the distraction of attention during home study. The extent of problems in six areas: (1) self-regulation, (2) technological literacy, (3) student isolation, (4) technological sufficiency, (5) learning resources, and (6) learning environments are significantly different. Among the suggestions, the students expected improvements in (1) teachers’ pedagogy, (2) students’ health, and (3) assessment scheme. Acknowledging the problems and putting forward suggestions for emergency remote teaching could contribute to the development of sustainable online teaching as a complementary mode of instruction in the new normal.

Measurement disturbances refer to any conditions that affect the measurement of some psychological latent variables, which result in an inaccurate interpretation of item or person estimates derived from a measurement model. Measurement disturbances are mainly attributed to the characteristics of the person, the properties of the items, and the interaction between the characteristics of the person and the features of the items. Although numerous researchers have detected measurement disturbances in different contexts, too little attention has been devoted to exploring measurement disturbances within the context of language testing and assessment, especially using graphical displays. This study aimed to show the utility of graphical displays, which surpass numeric values of infit and outfit statistics given by the Rasch model, to explore measurement disturbances in a listening comprehension test. Results of the study showed two types of outcomes for examining graphical displays and their corresponding numeric fit values: congruent and incongruent associations. It turned out that graphical displays can provide diagnostic information about the performance of test items which might not be captured through numeric values.

Measurement invariance (MI) refers to the degree to which a measurement instrument or scale produces consistent results across different groups or populations. It basically shows whether the same construct is measured in the same way across different groups, such as different cultures, genders, or age groups. If MI is established, it means that scores on the test can be compared meaningfully across different groups. To establish MI mostly confirmatory factor analysis methods are used. In this study, we aim to examine MI using the Rasch model. The responses of 211 EFL learners to the listening section of the IETLS were examined for MI across gender and randomly selected subsamples. The item difficulty measures were compared graphically using the Rasch model. Findings showed that except for a few items, the IELTS listening items exhibit MI. Therefore, score comparisons across gender and other unknown subgroups are valid with the IELTS listening scores.

Drawing on qualitative research, this study explored, from a complex dynamic systems theory perspective, the motivation of Burundi junior high school students simultaneously learning L2 French, L3s English and Kiswahili. It aimed to fill the gap in research on (1) changes in motivational dynamics and factors responsible for any fluctuations in the levels of motivation over time and (2) complex interactions between different learner variables among multiple language learners. Twelve school pupils who were all Kirundi native speakers participated in this study. Retrospective interviews were used to collect data relating to the students’ multilingual learning experiences over the period of their formal education. The findings indicated that the intensity of learning each target language fluctuated over time, with English generally enjoying the highest increase and Kiswahili the lowest and that different factors were responsible for such dynamic changes. Besides, complex interactions between the students’ L1, L2, and L3s linguistic knowledge and their foreign language learning motivations were revealed. These results indeed highlight the complex and dynamic nature of motivation in learning multiple languages. In light of these findings, practical implications are discussed based on the Burundi educational context.

AbstractA paradigm shift in education has led to implementing learner-centered pedagogy (LCP) which considers learners as the central element of the learning process, and it is progressively being encouraged in higher education. Examining the implementation of learner-centered pedagogy in English language teaching (ELT) context is important. While this paradigm of teaching has long been introduced to education in general and language teaching in particular, it is claimed that scant attention has been given to its implementation in Iranian EFL context. The present study was to compare the implementation of learner-centered pedagogy in assessment procedures at different Iranian universities. Therefore, using convenience sampling technique, 378 TEFL students from both genders and different ages (mostly 20 to 35 years old) were selected. To gather data, a reliable, valid researcher made LCP questionnaire was distributed among the participants. Gathered data were analyzed using one-way ANOVA. The results of the data analysis demonstrated that there was a significant difference between the performance of state university and Islamic Azad and non-state university, while no significant difference was observed between the performance of Islamic Azad and non-state university students. The outcomes can provide insights into considering learner-centered pedagogy in teaching to improve teaching English as a foreign language (TEFL) program. Moreover, they can be practical for teachers, material developers, as well as syllabus designers.

Over the last decade, Mobile-assisted Language Learning (MALL) has led to an authentic and contextual language learning process across the globe (Kukulska-Hulme, 2009). It has played a pivotal role in language learning in general and vocabulary learning in particular as a building block of academic writing. The current study examined the effect of a mobile application (i.e. AWL builder) on academic vocabulary learning among sophomore university students in applied linguistics. The study also focused on measuring students' perceptions and problems in utilizing mobile-assisted applications in acquiring English academic vocabulary. Accordingly, using convenience sampling procedures the participants were divided into experimental (N =36) and control (N = 36) groups. The experimental group used a mobile application (i.e. AWL builder), while the control group used a traditional approach. Furthermore, to answer research questions academic vocabulary pre-and post-tests and a questionnaire were employed. The findings show that the AWL group showed prominent performance in academic vocabulary tests. The current study concludes that instructors should take into account mobile devices as useful supplementary tools to enhance L2 academic word retention and include them in regular language curriculum.

This article tries to delineate different aspects of Mediated Learning Experience (MLE) in detail: MLE as a model of learning in psychology, MLE as a dynamic assessment methodology, and MLE as a basis for designing a course. This article tries to delineate different aspects of Mediated Learning Experience (MLE) in detail: MLE as a model of learning in psychology, MLE as a dynamic assessment methodology, and MLE as a basis for designing a course. MLE, well-known as Feuerstein's theory, is presented as a model of learning in psychology for enhancing cognitive functioning and problem-solving skills in children with cognitive challenges. Some other studies and scholars such as Poehner (2008) consider MLE as a dynamic assessment methodology because in dynamic assessment, assistance emerges from the interaction between the mediator and the learner. The other studies look at MLE as a holistic and integrative approach which is able to prepare a course. Definition of MLE principles and a meticulous and elaborate analysis of the first five MLE principles in different studies, entitled as MLE Taxonomy, are presented in a table at the end of the article.

This quasi-experimental study aimed to investigate the effects of dynamic assessment employed by teachers on promoting Iranian EFL learners’ stances in academic writing. For this purpose, three intact writing classes were selected by convenience sampling from BA students of English translation at Isfahan (Khorasgan) Branch, Islamic Azad University. The Quick Oxford Placement Test (QOPT) was administered to them, and those whose scores matched the intermediate band score of QOPT were selected. In general, 35 homogeneous students were selected from each class and randomly assigned into two experimental groups and one control group. A writing test was administered to all groups as the pre-test at the onset of the semester. The experimental groups were taught by the researcher and passed five different quizzes during the semester. The three groups were post-tested at the end of the semester. The results illustrated that both teacher and peers’ dynamic assessment effectively improved Iranian EFL learners’ stance in academic writing.

One strategy that eases the process of teaching argumentative writing might be teaching them how to express their thoughts, beliefs, and in general, ideologies in academic essays. This study aimed to investigate the effect of teaching writing skills on ideology transfer in the academic writings of EFL students. To this end, a sequential mixed-methods design was used. Participants were 80 male and female IELTS candidates who were selected based on some criteria such as proficiency level, age, and educational background. A sample Mock Writing Task 2 and a sample IELTS Writing Task 2 were used as instruments in the pre-test and post-test respectively. Learners’ essays produced during these stages were analyzed based on Fairclough’s (2001) three-dimensional model of critical discourse analysis: description, interpretation, and explanation. To analyze the data, content analysis methods were applied during which discursive strategies used by the candidates were identified and coded, and the frequency and percentage of them were calculated. After the analysis, the following themes were extracted in the participants’ writings, as representing ideology transfer: tendency towards representation of identity, use of active voices, use of first-person pronouns, social views, author visibility, ideology-laden concepts, and idea development. Moreover, there were significant changes in the post-test writings of the participants in terms of the number of discursive strategies used to express ideology. This shows that teaching writing skills can significantly affect EFL learners’ ability to transfer their ideology into academic writing. The findings can have some implications for EFL learners, teachers, and curriculum planners.
