Despite extensive research on assessing collocational knowledge, valid measures of academic collocations remain elusive. With the present study, we employ an argument-based approach to validate two Academic Collocation Tests (ACTs) that assess the ability to recognize and produce academic collocations (i.e., two-word units such as "key…

Based on theories on vocabulary knowledge, grammar knowledge, and reading comprehension subcomponents, ten attributes/subskills were defined for 50 items from relevant subtests of TEM4 (Band Four of Test for English Majors in China). Cognitive diagnosis was conducted on the TEM4 data of the randomly sampled 2285 examinees (roughly at the B2 level)…

Bilingual children's total vocabulary in each of their languages is often smaller than that of monolinguals. In their seminal study, Bialystok et al. (2010. 'Receptive vocabulary differences in monolingual and bilingual children.' "Bilingualism: Language and Cognition" 13 (4): 525-531) divided children's vocabulary into 'home' and…

The purpose of this study was to compare the functioning of five restrictive CDMs, including DINA, DINO, A-CDM, LLM, and RRUM, against the G-DINA model to identify the best-fitting CDM which can better explain the interaction underlying the attributes of the reading comprehension section of an Iranian high-stakes language proficiency test. To this…

Recent studies in the second language acquisition of negation have focused on polarity items and their licensing contexts. Although several studies show a correlation between higher degrees of second language (L2) proficiency and the acquisition of the target L2 structures, less attention has been given to the relation between the acquisition of…

Vocabulary knowledge plays an important role in writing. Previous research has examined the relationship between various aspects of vocabulary knowledge and independent writing performance and limited attention has been given to integrated writing such as summary writing. Our study investigated the contribution of two aspects of vocabulary…

Research is scarce about the lexical processes undertaken by thousands of L2 learners worldwide who already command one or more languages. Some aspects involved in lexical organisation and production, such as clustering and switching, have been traditionally approached through manual methods, which depend on subjective judgments of semantic…

Background: Vocabulary learning in a second language (L2) encompasses crucial aspects, including single words and collocations. Research indicates that L2 learners can incidentally learn single words from captioned videos, but less is known about the incidental learning outcomes of collocations, let alone the differences in learning gains for…

Enhancing students' lexical fluency and academic performance in speaking exams presents a significant challenge for English as a foreign language (EFL) instructors. The pursuit of effective tools to engage students and facilitate their learning process has been ongoing. The incorporation of technology in EFL learning contexts, particularly through…

This study aimed to develop a Vietnamese word recognition test for Taiwanese undergraduate students and to investigate students' performances at different learning stages. The formal test consists of 100 words as test items. With each word, test takers were asked to select the correct Vietnamese word form corresponding to the pronunciation they…

The Vocabulary Size Test (VST) measures English learners' decontextualised receptive vocabulary knowledge of written English and has nine bilingual versions with multiple-choice options written in other languages. This study used the English-Japanese version of the VST to investigate the extent to which loanword items were answered correctly by…

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…

This study sought to identify the challenges and needs of TOEFL iBT candidates in achieving C1 level scores in the speaking and writing sections of the exam. To this end, the researcher employed a mixed-method approach to collect data from a population of 46 students, both male and female, between the ages of 22 and 30. The participants were…

Many overseas students in Higher Education in the UK struggle to understand the compulsory texts for their course, and obtain lower scores for their modules than their monolingual peers. While the existence of this achievement gap is well established in the literature, little is known about the ways in which overseas students in HE with limited…

Word frequency has a long history of being considered the most important predictor of word difficulty and has served as a guideline for several aspects of second language vocabulary teaching, learning, and assessment. However, recent empirical research has challenged the supremacy of frequency as a predictor of word difficulty. Accordingly,…
