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).

This research explores language assessment practices and training preferences in Iranian English as a Foreign Language (EFL) teaching, aiming to provide valuable insights into the current landscape among 363 Iranian EFL teachers. Data collection included diverse demographics, facilitating a thorough analysis of assessment practices and preferences. Statistical analyses, such as chi-square tests, revealed a significant gap between the perceived importance and the actual proficiency of Iranian EFL teachers. Speaking skills are prioritized while listening comprehension is least emphasized. Common assessment methods include active class participation, oral presentations, and closed-ended tests, with underutilized methods suggesting a need for broader teacher development programs. The study underscores the diverse terminology used for teacher-mediated assessments, emphasizing the multifaceted nature of EFL assessment practices. In summary, the paper highlights the significance of tailored assessment literacy programs to bridge the gap and enhance English language teaching in Iran.

This study aimed to investigate the effect of task type (i.e., sentence fill-in/sentence writing) and word type (i.e., real/ pseudo) on initial learning and retention of 10 word meanings, taking the predictions of Involvement Load Hypothesis (ILH) and Technique Feature Analysis (TFA) into account. Participants were 59 intermediate-level EFL learners from eight intact classes. Each intact class was randomly assigned to one of the four learning conditions: 1) sentence fill-in with real words, 2) sentence writing with real words, 3) sentence fill-in with pseudowords, and 4) sentence writing with pseudowords. Initial learning was measured by administering a meaning recall test immediately after the tasks and medium-term retention was measured by administering the same test with rearranged items one week after the tasks phase. The results of a mixed between-within subjects ANOVA did not show any significant interaction effect between test time and learning condition. Furthermore, the main effect for learning condition was not statistically significant but there was a significant main effect for test time, suggesting that participants’ scores dropped significantly from the immediate posttest to the delayed posttest. The findings of two independent-samples t-tests failed to show any significant difference between the immediate and delayed posttest scores of the participants who received either sentence fill-in or sentence writing tasks. However, some tentative findings demonstrated that those participants who were assigned to the sentence writing task achieved higher scores on the posttests. This finding indicates that TFA has probably more predictive power than ILH and it also provides some evidence in favor of the heavier weight of the evaluation component of the ILH when compared to its search component.

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.

This study set out to examine how stereotypes as social psychological phenomena are enacted in everyday discourse. Besides discussing how ingroups and outgroups are formed in mundane talk, it is argued that stereotypes are ideological constructs that are jointly achieved in social contexts. Moreover, it is assumed that the ways in which stereotypes are constructed and discussed in discourse are informed by a number of underlying moral conceptualizations which might justify the potential face-threatening acts and the impoliteness inherent in prejudiced talk targeted to a third party. The study is an ethnographic case study informed by an eclectic approach to the analysis of data so as to shed light on how the expression of thoughts and feelings are constructed as talk in ordinary social interactions unfolds and what these expressions achieve. The analyses revealed that the construction of outgroup stereotypes is a mutual accomplishment and possibly a face-threatening act moderated by mitigating discourse features

Vocabulary learning can occur incidentally when explicit and implicit cognitive processes are at work. The present study investigated how frequently a set of (implicit/explicit) lexical strategies was used by Iranian learners of English while reading journalistic texts for comprehension, and how effective they were regarding vocabulary retention in incidental vocabulary learning. Also, it examined the role of gender in lexical strategy use in such a context. To this end, 40 upper-intermediate learners of English, including 20 males and 20 females, were selected and asked to read journalistic texts. To collect the data, think-aloud and a retention test (Vocabulary Knowledge Scale) were used. Descriptive and chi-square data analyses revealed that the most frequent lexical strategy was consulting a dictionary (particularly a bilingual dictionary), followed by inferring (particularly contextual strategies) and ignoring strategies. The male participants were found to use inferring strategies more frequently whereas the female participants were found to use the ignoring strategy more frequently. Moreover, significant differences were observed between explicit and implicit strategy types with higher lexical use and retention effect for explicit ones. Findings provide implications for L2 vocabulary learning. 

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.

The provision of scaffolding entails contingent assistance given to learners. Despite the proliferation of research on scaffolding, scant attention has been devoted to studying the modes of classroom interaction in fulfilling various scaffolding intentions in content-based instruction (CBI). To narrow the gaps, the present qualitative study embarked on an investigation of science teachers’ scaffolding in four modes proposed by Walsh (2006), namely managerial, classroom context, skills and systems, and materials modes. Four science teachers participated in this qualitative study, and 12 sessions of science classes were observed and analyzed deductively based on four classroom modes through conversation analysis (CA). The content analysis of the videotaped recordings indicated that managerial and materials modes were frequently used to enhance students’ comprehension and develop classroom interaction. The findings evidenced that pedagogical objectives were mostly related to cognitive structuring, contingency management, and direction maintenance requirements. Furthermore, the findings revealed that students’ engagement and involvement through recruiting interest was the only scaffolding intention employed in all four modes to involve students in the learning process. The findings can provide insights to teachers and teacher educators in the realization of distinct scaffolding intentions in various classroom modes by delineating the interrelationship between language use and teaching purpose.  

Iranian high school students confront various challenges in understanding reading passages and learning vocabulary since appropriate process-oriented assessment techniques with constructive and communicative feedback are not practiced to consolidate instruction and learning. The effect of formative assessment (FA) retelling strategy on vocabulary knowledge and understanding passages was investigated and scrutinized in this quasi-experimental study in the EFL context. Thus, a sample of 48 intermediate EFL students was selected and assigned to two intact groups. The retelling assessment was implemented for the experimental group (EG), while the product-oriented summative assessment was applied to the control group (CG). The pre-test scores were taken at the first phase of the study followed by the eight-week assessment process. Finally, the post-test scores were taken. For the purpose of the analysis, the Independent Samples T-test and the one-way  ANCOVA were utilized to compare and contrast the mean scores. The findings were in favor of the retelling technique which developed the vocabulary command and text comprehension in the EG. Moreover, little or no significant impact was revealed for the product-oriented assessment in the CG. The findings can be pedagogically rewarding for learners, teachers and theoreticians and may cast light on SLA research in applying FA techniques.
