Predicting students’ performance in a course is one of the major aims of educational data mining systems. In the present study, two and three-layer artificial neural networks (ANN) and neuro-fuzzy systems (NFS) were used to predict Iranian EFL learners’ final scores and compare them with scores given by their instructor. Sixty-six students’ scores in an English reading comprehension course comprising of five sub-scores of midterm (out of 40), quiz (out of 60), final (out of 50), class participation (out of 5) and bonus (out of 2) were used for training the systems. Two and three-layer ANNs and an NFS were trained to predict students’ final scores using training data. Researchers compared the students’ final scores given by their instructor and those achieved through the ANNs and NFS. The results showed that the NFS could predict and deliver scores that were closer to the linear sum of students’ scores. Moreover, three-layer ANN had a better performance than the two-layer ANN. According to these results, data mining techniques could deliver an accurate estimate of students' abilities in a particular course.

The present study investigates the efficacy of preparation time in four speaking tasks of TOEFL iBT. As the current pre-task planning time offered by ETS is very short, 15 to 30 seconds, we intended to explore how the test-takers’ speaking quality would change if the preparation time was added to the response time, giving the respondents a relatively longer online planning opportunity. To this aim, two groups of TOEFL iBT candidates were studied under pre-task and online planning conditions. Totally, 384 elicited speaking samples were first transcribed and then measured in terms of complexity, accuracy, and fluency (CAF). The results yielded by a series of One-way MANOVA revealed the online planning group significantly outperformed the pre-task planning group in terms of accuracy and fluency across all four speaking tasks. Although with less robustness, the online planners had significantly higher speech complexity represented by lexical diversity and left-embeddedness. The results obtained through this study may challenge the efficacy of the currently provided preparation time in TOEFL iBT speaking subsection.

Rested in analogical theories of learning and syntactic configuration in discourse, this study attempted to explore the efficiency of rule-based, exemplar-based, and analogy-based corrective feedback in the writings of Iranian EFL learners regarding the third- person singular’ s. To this aim, three intact classes, each containing 25 students, were assigned to analogy-based, rule-based and exemplar-based groups at random in which the teacher accentuated the learners’ errors by different feedback types. Post-tests (immediate and delayed) were used to test the learners’ acquisition of the target grammar under question and the efficacy of corrective feedback varying in mode. The results of the study indicated significant delayed gains for analogy-based corrective feedback. No evident gain was found for exemplar-based or rule-based types. Descriptive statistics demonstrate diverse patterns over progressive testing times, where, unlike the other two corrective feedback types, the analogy-based group displayed the worst performance on the immediate post-test but nonetheless exhibited advances and progress on the delayed post-test.

"Lexical Chains" is one of the newest branches of statistical semantics, which is defiend as the process of identifying words that have semantic relationship with each other, and help us to identify the topic and main content of the text. In this research, we aim to determine lexical chains of sermons No. 87 and 191 of Nahj al-Balaghah, based on the theory of "Saxena", as well as "Barzilay" and "Elhadad", using the descriptive-analytical and statistical method. The results show that in both sermons, the semantic relation "Antonym" has the most frequency. In sermons No. 87 and 191, respectively, 8% and 5% of the chains are "strong chains", and play the main role in determining the main themes of the sermons. According to the data, choosing the title "religious, ethical, scientific" for the sermon No. 87, and "moral, ethical, social, intellectual" for the sermon No. 191 -contrary to what "Mohammad Dashti" mentioned for them- seems more appropriate.

In recent years, there has been increasing interest in understanding how cognitive skills influence second language acquisition. Cognitive control, a set of mental processes that include attention, inhibition, and working memory, has been shown to play a significant role in language learning. This study examines the impact of cognitive control skills on language development among adult Iranian English learners, comparing it both in online and in person settings. Forty adult EFL learners were divided into two groups and underwent a 9-week instructional period, with cognitive control skills assessed using the Attention Network Task (ANT), working memory tasks, and a Raven’s IQ test. Data were analyzed using Pearson correlation, regression, and ANCOVA to determine relationships between variables. The results of the study revealed that while aspects of cognitive control like orienting and altering do not have a significant impact on language development, the more complex, controlling aspect exhibits a positive relationship (F=4.937, p=0.033). This relationship was contingent upon controlling for differences between post-examination and primary examination of ANT results, indicating that controlling attention is a stronger predictor of language outcomes. Furthermore, the study demonstrated that the mode of instruction—online or in-person—has no significant impact on this relationship (F=0.009, p=0.925), suggesting that cognitive control operates independently of teaching mode. The study’s findings suggest that educators and curriculum developers should emphasize activities targeting the controlling component of cognitive control in language learning, as this is linked to better language development. Additionally, since the mode of instruction does not significantly impact this relationship, effective language instruction can be delivered in both online and in-person settings, providing flexibility in course design.

In order to cater for the ever-increasing demand for learning English, private language institutes have mushroomed across Iran. These institutes adopt different policies such as designing their own Teacher Training Course (TTC), following the syllabus of Certificate for Teaching English to Adults (CELTA), or localizing it for the Iranian context to train competent English teachers. Surprisingly, there exists little research evaluating these TTC's or investigating if localizing CELTA is an effective strategy for the Iranian context. This study aimed to fill this gap by delineating the steps taken by a widely-known Iranian language institute in localizing CELTA for the Iranian context, and secondly to determine if the teachers were satisfied with this localized TTC. Data collected through the websites and interviews were subjected to conceptual content analysis; while the data mined through evaluation questionnaires were analysed through quantitative descriptive statistics. The findings revealed that the Iranianized TTC suffered from discrepancies such as unreliable selection of the participants, lack of opportunities for teaching practices, not observing experienced teachers' classes, and focusing on received rather than experiential knowledge. These findings are discussed, and a number of practical suggestions are offered to improve the Iranian TTC.

The documentation of test takers’ achievements has been accomplished through large-scale assessments to find general information about students’ language ability. To remove subjectivity, Cognitive Diagnostic Assessment (CDA) has recently played a crucial role in perceiving candidates’ latent attribute patterns to find multi-diagnostic information rather than single proficiency classification. However, there are some gaps in the literature about in detail investigation of test takers’ listening comprehension language ability in responding to placement test items of a public English language center. The present study aims to validate an English placement test at a language center through a retrofitting process. In an exploratory mixed-method design, 449 participants from the same language center, including 274 females and 175 males, were selected. The performance of randomly selected participants in a language center placement test was analyzed by applying the GDINA model from R-studio packages, to detect Differential Item Functioning (DIF). Results of the study revealed DIF in some items since there is some bias in test items. The implication of this study is to provide meaningful interpretations of respondents’ attributes and improve teaching and learning by finding the strengths and weaknesses of candidates. For this purpose, the findings derived from the result of the study can raise the awareness of test developers in preparing unbiased items for the placement test, and at the same time, assist test-takers to become more critical of their English language achievements. It is also helpful for materials developers to become aware of developing materials free from bias.

This paper discusses the use of Persian in comparison with Dari, a dialect of Persian language used in Kerman, one of the cities of Kerman Province located in southeast Iran. It is based on a random selection of 47 subjects from different sex, age, and occupational groups of Zoroastrian people with different levels of education in seven domains, i.e. family, friendship, neighborhood, transaction, education, government, and employment. In this study, the subjects were asked to determine which language they use in different domains on Likert’s 4-point scale. After collecting the data by the use of a questionnaire with 30 situations in the seven domains and analyzing them, the researcher concluded that there is a Persian-Dari diglossia in Zoroastrian speech community in which Dari functions as the Low language whereas Persian is the High one. As a matter of fact, Dari has been restricted to family domain and the young generation has lost it to a large extent.

A bulk of research has revealed that emotions play a crucial role in different aspects of second/foreign language (L2) education. However, the emotions that English as a foreign language (EFL) students experience during assessment have been neglected, so far. Against this backdrop, this qualitative study intended to unveil the typologies, antecedents, and outcomes of assessment-related emotions of 24 Iranian EFL undergraduate students studying applied linguistics. To this end, a semi-structured interview and a narrative frame were employed. The results of the thematic analysis demonstrated that undergraduate EFL students experienced different positive and negative emotions before, during, and after assessment practices at the university. Furthermore, it was found that “teacher”, “tasks”, and “textbook” were the most frequent causes of the participants’ perceived emotions in assessment. Concerning the outcomes of assessment-induced emotions, the results demonstrated that “burnout”, “frustration”, “demotivation”, “stress”, and “self-doubt” were the most frequent negative outcomes, while “motivation”, “learning”, “pride”, and “excitement” were repeatedly posited as positive outcomes. Finally, the study enumerates some implications for L2 educators and researchers concerning the role of emotions in assessment processes and practices.
