There are few published estimates of vocabulary sizes amongst students in tertiary education. Research does not offer estimates of the vocabulary size tertiary students might be expected to possess, though estimates exist for K-12 education, some EFL contexts, and the general population. Such research is important. For reading comprehension during…

This study examined the semantic features of the simulated mini-lectures in the listening sections of the International English Language Testing System (IELTS) and the Test of English as a Foreign Language (TOEFL) based on automatized semantic analysis to explore the content validity of the two tests. Two study corpora were utilized, the IELTS…

Corpus-based studies have offered the domain definition inference for test developers. Yet, corpus-based studies on temporal fluency measures (e.g., speech rate) have been limited, especially in the context of academic lecture settings. This made it difficult for test developers to sample representative fluency features to create authentic…

Language borrowing from sources is a phenomenon used by developing writers as they are learning academic language, though there is much to be learned about how younger students borrow from sources. This study explores student writing, from a sample of 166 diverse middle graders, across topics to determine patterns in borrowing from instructional…

The central foundation of knowledge is through grasping what is being read. Therefore, it is significant to recognise the difficulty level of a reading text for better and comprehensive understanding. The present study is an attempt to identify the word frequency level and lexical coverage of the Malaysian University English Test (MUET) reading…

This study explored the effects of three types of lexical tools (MOOCs, E-dictionaries, and lexical concordancers) and three types of lexical applications (technology-mediated communication-based applications (TMCA), Anki as an e-flashcard application, and WordUp as a dedicated lexical application) on learning academic core words among a sample of…

VocQGen is an automated tool designed to generate multiple-choice cloze (MCC) questions for vocabulary assessment in second language learning contexts. It leverages several natural language processing (NLP) tools and OpenAI's GPT-4 model to produce MCC items quickly from user-specified word lists. To evaluate its effectiveness, we used the first…

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,…

Pragmatic markers perform important communicative functions, but they can be difficult to learn in a second language because of their multifunctionality and lack of salience during communicative events. This study has two goals: (1) to describe the communicative functions of the pragmatic marker "I mean" in academic discourse; and (2) to…

To have more information about the English words known by second language (L2) speakers, we ran a large-scale crowdsourcing vocabulary test, which yielded 17 million useful responses. It provided us with a list of 445 words known to nearly all participants. The list was compared to various existing lists of words advised to include in the first…

Despite previous research suggesting that first language (L1) use fulfills important functions in collaborative writing (CW) tasks, research has yet to examine whether L1 or second language (L2) use may lead to variation in the lexico-grammatical aspects of learners' collaborative texts and the pair talk. Using a corpus-based approach, this study…

Investigating lexical richness is a continuing concern within vocabulary studies. The present study aims to contribute to this growing area of research by exploring EFL learners' free active vocabulary by dividing them into groups based on their receptive vocabulary. It seeks to explain the role of different essay types and proficiency levels…

As a high-stakes standardized test, IELTS is expected to have comparable forms of test papers so that test takers from different test administration on different dates receive comparable test scores. Therefore, this study examined the text difficulty and task characteristics of four parallel academic IELTS reading tests to reveal to what extent…

Knowledge of collocations is essential for English academic writing. However, there are few academic collocation referencing tools available and there is a pressing need to develop more. In this paper, we will introduce the ACOP (Academic Collocations and Phrases Search Engine), a newly developed corpus-based tool to search large academic corpora.…

A key piece of a validity argument for a language assessment tool is clear overlap between assessment tasks and the target language use (TLU) domain (i.e., the domain description inference). The TOEFL 2000 Spoken and Written Academic Language (T2K-SWAL) corpus, which represents a variety of academic registers and disciplines in traditional…
