Despite the well-established role of lexis in proficiency in the four skills, a great deal of research has focused on the importance of vocabulary breadth and depth in reading. Therefore, the neglect of productive skills has motivated recent calls to inspect the impact of lexical dimensions on writing ability. Using Partial Least Squares…

This study examines the effects of the continuation task and the model-as-feedback writing task (MAFW) on English as a foreign language (EFL) vocabulary learning. Three classes of intermediate-level Chinese EFL learners were randomly assigned to a continuation group, a MAFW group, and a control group. Three aspects of vocabulary knowledge --…

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…

In spite of the proliferation of research studies on vocabulary knowledge, investigating the relationship between self-regulation, vocabulary size, and collocational knowledge among English as a Foreign Language (EFL) learners has received scant attention. The current study aimed to investigate whether vocabulary and collocation size can explain…

This paper presents data capturing Korean university students' familiarity with English online acronyms, examines factors that may predict this familiarity, and presents an explicit instruction intervention involving vocabulary knowledge of online acronyms. The Vocabulary Size Test (VST) measured students' vocabulary size, while a self-report…

This study investigated the relationships between two vocabulary learning strategies (guessing from context and dictionary use) and two aspects of vocabulary knowledge (receptive and productive vocabulary knowledge). One hundred and thirty-five university students in Japan completed a vocabulary learning strategies survey, the Updated Vocabulary…

In second language (L2) vocabulary studies there is continuing interest in tests of depth of vocabulary knowledge, measuring various aspects of word knowledge other than just the form--meaning link that is the focus of breadth (or size) tests. This study aimed to explore new formats that could be used as diagnostic tools for assessing depth of…

Despite the growing body of technology-assisted vocabulary intervention studies, few have addressed learning outcomes beyond target vocabulary and the interaction between the interventions and English language learners' (ELLs) initially different levels of vocabulary knowledge. The study examined the differential effects of a texting-based…

Performing a stay in a country where the L2 is the official language can provide the perfect immersion for L2 development (traditional study abroad). In the case of English learners, internationalization and the role of English as a lingua franca make it unnecessary to perform the stay in an English-speaking country. Hence, an increasing number of…

Although research shows that second language (L2) learners have major difficulties in developing their productive vocabulary skills, little research has been conducted on how to facilitate productive mastery of learned words. With this in mind, this study investigated the effects of task type and repetition frequency on improving receptive word…

This research and development study aimed to develop the prototype of virtual learning implemented in flipped classrooms and evaluate its effectiveness as a tool for developing Thai undergraduates' English receptive skills. To assess if the designed prototype is effective, a quasi-experimental method was employed. The experimental sample group…

Considerable research has been conducted on the advancement of mobile technologies to facilitate vocabulary learning and acquisition in a second language (L2). However, whether mobile platforms lead to a comprehensive mastery of both receptive and productive vocabulary knowledge has seldom been addressed in previous literature. This study…

The present study investigates the impact of meaningful input on L2 learners' vocabulary use and their fluency in oral performance (immediate and repeat tasks), as well as whether the effects are mediated by learners' prior vocabulary knowledge and working memory. Ninety university students learning English as a foreign language were randomly…

EL1 learners' receptive morphological words (root, inflected, and derived words) develop on different scales, but whether they develop similarly in EFL learners' language production is still unknown and deserves an examination. The answer may provide a clue to theoretical controversy about whether language learners' morphologically defined words…

This study aims to measure the longitudinal impact of a 60-hour adjunct instruction course, involving L2 content-based teaching with a systematic focus on form, on students' grammatical and lexical knowledge and on their receptive skills (i.e. reading and listening) in a foreign language higher education context. The participants were 52…
