Previous research has shown the differential effects of task-related prompts on syntactic complexity, grammatical accuracy, and lexical diversity when L2 learners use writing prompts to produce a piece of writing. However, the extent to which the freedom in the selection of prompts affects these linguistic facets in L2 argumentative essays is still unknown. The present study, therefore, was designed to investigate differences between syntactic complexity, grammatical accuracy, and lexical diversity in argumentative essays. Seventy-one upper-intermediate male and female Iranian English-as-a-foreign language (EFL) learners from Imam Khomeini International University in Qazvin and Safir Plus institute in Tehran participated in this study. Five-paragraph essays were used to collect data, and SPSS (version 25) was used to analyze the data. Results of multivariate analysis of variance (MANOVA) showed statistically significant differences between syntactic complexity, grammatical accuracy, and lexical diversity. Results from post-hoc analyses revealed statistically significant differences between lexical diversity and grammatical accuracy as well as lexical diversity and syntactic complexity, but no statistically significant differences were found between grammatical accuracy and syntactic complexity in argumentative essays.

This study compared the use of lexical bundles in authentic spoken language data with those of two English learning textbooks developed for IELTS preparation courses in Iran. The aim was to see if the language chunks available in the said textbooks were representative of the real-life language for which learners need to prepare. To achieve this aim, firstly, a list of lexical bundles was compiled based on Michigan Corpus of Academic Spoken English (MICASE) and British Academic Spoken English (BASE). Further, the list was used as a reference tool to analyze the language data of two IELTS preparation books published and widely used in Iran. The results highlighted some considerable differences between MICASE and BASE with regard to the use of lexical bundles in terms of their frequency, structure, and function. Moreover, it was revealed that the books under investigation shared only a scarce number of similar lexical bundles with MICASE and BASE as a whole. Therefore, they failed to be representative of the authentic language that people use in real world. Finally, the implications of the study are discussed, and several practical suggestions are made in order to inform teachers, material developers, and syllabus designers of the importance of related corpus linguistic studies.

In order to engage students in higher-level thinking, cognitive activation (CA) strategies have been advanced and utilized in mathematics. CA develops when learners are challenged, confronted with conflicts, asked to think and explain clearly on their learning, and realize connections between new and previous content. Extending the theme to English language teaching (ELT), this study investigated Iranian English language teachers’ knowledge and practice of cognitive activation writing strategies (CAWS). In so doing, a model was proposed based on a questionnaire that was developed and validated in the present study. Through this scale, knowledge and practice of CAWS by 213 English as a foreign language (EFL) teachers were explored. During a pilot phase, the reliability of the questionnaire was calculated to be .78 for the knowledge section and .81 for the practice section. Two items in each section were removed after conducting exploratory factor analysis. Ultimately, the confirmatory factor analysis indicated that the proposed model was fit for the data. Five components were confirmed as constituents of CAWS for the knowledge section, and four components were identified for the practice section. The findings revealed that Iranian EFL teachers were already familiar with the CAWS and purportedly practiced them in their writing classes. Using the scale in the process of writing instruction can provide ELT practitioners with a helpful platform for relating to CA strategies and empowers learners to accomplish tasks such as problem-solving in their writing assignments, similar to what is practiced in mathematics.

Placing non-native speakers of English into appropriate classes involves mapping placement test scores onto proficiency levels based on predetermined cut scores. However, studies on how to set boundaries for different levels of proficiency have been lacking in the language testing literature. A top-down approach to standard setting in which a panel of experts set cut scores has dominated the typical standard setting procedure. A less utilized approach is to proceed bottom-up by clustering learners based on test scores. The purpose of this study was to fill this gap by examining Education Testing Services (ETS)’s mapping of TOEFL® iBT Test scores to the Common European Framework of Reference (CEFR) levels. The study examined TOEFL® iBT score data from ICNALE (International Corpus Network of Asian Learners of English) and conducted optimal Kernel Density Estimation to find peaks in the distribution of test scores. In addition to the number of peaks, the local minima of the resulting distribution were chosen as boundaries of cut scores for delineating different ability groups. This method of separating scores, also known as contrasting groups, finds clusters of test takers based on maximum differences in scores. The results showed that ETS’ guide for cut scores linking to CEFR levels was comparable to Kernel Density Estimation with some exceptions, namely two out of three cut scores were found to be similar. Implications are discussed in terms of test-centered versus examinee-centered method of standard setting and the need to consider the demographics of the examinee population in determining cut scores.

Language Learners’ epistemological beliefs (LLEBs), as their conceptions about the nature of L2 knowledge and L2 knowing, are among the determinants of the route and the outcome of language learning; however, research into their dimensional and developmental nature is at the premium. This qualitative study was designed to (a) unravel the dimensions of LLEBs, and (b) delineate data-driven dimension-specific developmental patterns. Following “maximum variation” sampling, data obtained in 30 one-to-one semi-structured oral interviews were subjected to directed qualitative content analysis to detect utterances related to L2 knowledge and knowing conceptions. Seventeen themes each reflecting beliefs about one of epistemological beliefs’ core dimensions (i.e., knowledge certainty: N=4; simplicity: N=4; source: N=5; and justification: N=4) were extracted, and inter-coder agreement ensured. In the second phase, data obtained in three separate focus-group interviews from another 18-member sample selected via “critical case sampling” were analyzed to sketch differential dimension-related beliefs, if any, and sketch possible developmental paths. The results showed clear distinctions across the three sub-samples in terms of all the 17 LLEBs’ themes extracted in phase 1, roughly reflecting Baxter Magolda’s (1992) four-point epistemological development continuum from “absolute knowing” through “transitional knowing” and “independent knowing” to “contextual knowing.” The findings indicate the dimensionality and developmental nature of LLEBs, and the alignment of LLEBs with research on domain-general epistemology.

Over the years, much research has been done on the role of tasks in L2 learning, but little is known about how sequencing tasks affects listening comprehension. Thus, the present study evaluated the effect of sequencing repeated familiar tasks (SRFT) along three dimensions of complexity i.e. +/- visual support, +/- few elements, and +/- planning time. Sixty upper-intermediate EFL learners were randomly selected as experimental group (n=30) and control group (n=30) in this experimental research. To control the homogeneity of the participants and their topic familiarity, the Success Placement Test designed by Fricker (2007) and the listening comprehension test (developed by Richards, 2005) were administered respectively. Then the posttest of listening for IELTS which included 3 levels of task complexity was employed to analyze the results of SRFT. The participants in the experimental group were required to listen to keeping fit tasks ordered from simple to complex tasks during 10 sessions. The participants in the control group performed disordered tasks. T-test and SPSS version 20 were utilized to analyze the tests. Before employing treatment, the placement test addressed that both of the groups obtained no marked difference level of English language knowledge. They also displayed the same topic familiarity of listening comprehension on the pretest. In the end, the t-test indicates a positive influence of SRFT for the experimental group in the posttest. The findings of this study recommend sequencing tasks in English classes as a basic tool to improve the listening performance of learners.
