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…

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…

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…

Research addressing the relationship between vocabulary knowledge and second language (L2) listening comprehension has been conducted mostly using measures that tap orthographic vocabulary knowledge. The few studies that have used measures that tap phonological modality to delineate the relationship between vocabulary and L2 listening have focused…

Recently vocabulary studies have mainly focused on two forms of vocabulary acquisition: incidental and intentional vocabulary acquisition. For incidental vocabulary acquisition, Task-induced Involvement Load Hypothesis (TILH) was put forward by Hulstijn and Laufer (2001) to investigate the vocabulary tasks by comparing their levels of involvement…

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 examined the effects of involvement load-based tasks on vocabulary learning in a foreign language, as well as the extent to which task effects are predicted by learners' metacognition (i.e. metacognitive knowledge and regulation). A total of 120 Chinese university students of English as a foreign language (EFL) were randomly assigned to…

This study examined the receptive vocabulary knowledge and lexical developmental patterns of the 3000 most frequent words among 953 university L2 learners of Spanish at different stages in their language studies, taking into consideration the effect of high school instruction on high-frequency vocabulary knowledge. Results confirm that even…
