This study applied the Mixed Rasch Model (MRM) to the listening comprehension section of the International English Language Testing System (IELTS) to detect latent class differential item functioning (DIF) by exploring multiple profiles of second/foreign language listeners. Item responses of 462 examinees to an IELTS listening test were subjected…

This controlled experimental study investigated the interaction of variables associated with rating the pronunciation component of high-stakes English-language-speaking tests such as IELTS and TOEFL iBT. One hundred experienced raters who were all either familiar or unfamiliar with Brazilian-accented English or Papua New Guinean Tok Pisin-accented…

This paper investigates the comparability between the video-conferencing and face-to-face modes of the IELTS Speaking Test in terms of scores and language functions generated by test-takers. Data were collected from 10 trained IELTS examiners and 99 test-takers who took two speaking tests under face-to-face and video-conferencing conditions.…

Over the decades, extensive research efforts have been directed towards classifying and evaluating motivational teaching behaviours. Recent calls in motivational research, however, have emphasised the need to investigate teachers' perspectives on how they develop effective motivational strategies so that implications for motivational teaching are…

Comparing language tests and test preparation materials holds important implications for the latter's validity and reliability. However, not enough studies compare such materials across a wide range of indices. Therefore, this study investigated the text complexity of IELTS academic reading tests (IRT) and IELTS reading practice tests (IRPrT).…

This study explores the impact of sociocultural theory-based instruction on enhancing L2 learners' writing skills including grammatical accuracy, coherence, cohesion, task response, and lexical resources for the IELTS. To this end, a cohort of 40 participants, spanning intermediate and advanced proficiency levels, was divided into experimental and…

Research on the use of standardized test scores in higher education reveals significant variations in attitudes and perceptions of language proficiency tests among test score users. Most test score users have limited knowledge about test score interpretations in terms of what English as additional language (EAL) students typically know and can do…

The implicit sociocultural functioning of the "content" of high-stakes English language proficiency tests is a rarely-explored concern in language assessment. This study attempts to bring critical views of language testing and critical discourse studies together to examine the content of IELTS preparation materials in search of topics…

Purpose: This study attempts to evaluate the effect of the corpus-based inductive teaching approach with multiple academic corpora (PICA, CAEC and Oxford Corpus of Academic English) and conventional deductive teaching approach (i.e., multiple-choice items, filling the gap, matching and underlining) on learning academic collocations by Iranian…

Large-scale standardized ESL tests such as the International English Language Testing System (IELTS) are widely used around the world to measure the language proficiency of test-takers and make different decisions based on their scores. Reading comprehension is an integral part of such tests which requires test-takers to read passages and answer a…

Scalar implicatures involve inferring the use of a less informative term (e.g. some) to mean the negation of a more informative term (e.g. not all). A growing body of recent research on the derivation of scalar implicatures by adult second language (L2) learners shows that while they are successful in acquiring the knowledge of scalar…

From the perspective of complexity theory and based on Robinson's Cognition Hypothesis and the Triadic Componential Framework, this paper investigated the effect of manipulating task complexity along resource-dispersing dimension on L2 written performance. The results showed that: 1) Significant interactive effects were found between the two…

This study compares the effect of ZPD feedback with explicit feedback on accuracy in second language (L2) writing. It also examines the effect of focused vs. unfocused ZPD feedback on L2 writing development during teacher-student tutorial sessions. Four participants wrote five persuasive essays and were provided with ZPD or explicit feedback…

This paper investigates the attitudes of 246 English teachers from Outer and Expanding Circles (EC and OC) towards the global spread of English and the challenges underpinning international proficiency tests. Using a questionnaire, supplemented with interviews with a smaller group of teachers, this study explores how EC and OC teachers perceive…

No study has investigated the relationship between student engagement per se and student motivation within second language (L2) pragmatics, notwithstanding the significance of engagement for L2 learning. The present study aimed to explore the effects of two global motivational orientations (autonomous and controlled motivations) on behavioral…
