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…

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 set out to investigate the relationship between L2 vocabulary knowledge (VK) and second-language (L2) reading/listening comprehension. More than 100 individual studies were included in this meta-analysis, which generated 276 effect sizes from a sample of almost 21,000 learners. The current meta-analysis had several major findings.…

This study explores whether middle-school students can exploit explicitly addressed crosslinguistic lexical similarities between German and English to learn vocabulary more efficiently. Across six weeks, 260 Swiss German learners of English as a foreign language (17 classes) completed three vocabulary learning tests (T1, T2 and T3). Additionally,…

This study employs eye-tracking to investigate how first (L1) and second language (L2) glosses affect lexical uptake and reading behaviors in L2 learners of English. The study also explores the relationship between lexical uptake and reading behaviors as a function of gloss type. To investigate this, 81 Korean university students were asked to…

The present study investigates the effects of two subsequent learning contexts, formal instruction (FI) at home and a 3-month stay abroad (SA), on vocabulary acquisition in English as a foreign language (EFL) writing and speaking. Data were collected from 30 Catalan/Spanish learners of English before and after each learning period using a written…

The present study examined the interaction effects between teachers' choice of language in lexical explanation and second language (L2) learners' proficiency level on the learning of phrasal verbs and listening comprehension in a meaning-focused listening activity. Undergraduate L2 learners with two different levels of proficiency (intermediate…

The extent to which learners benefit from instruction may be largely dependent on their individual abilities. However, there is relatively little work on the interaction between instructional effectiveness in second language learning and learner individual factors. In this study, we investigated the relationship between instruction, individual…

If known words can be defined psycholinguistically as "form-meaning mappings", the present article investigates whether prompting learners to evaluate whether the form of a new second language (L2) word fits its meaning generates "mapping elaborations" that aid recall. Thirty Dutch-speaking upper-intermediate learners of…

This study investigated Vietnamese EFL learners' knowledge of verb-noun and adjective-noun collocations at the first three 1,000 word frequency levels, and the extent to which five factors (node word frequency, collocation frequency, mutual information score, congruency, and part of speech) predicted receptive knowledge of collocation. Knowledge…

This study investigates a teacher's L1 use during focus-on-form episodes (FFEs). FFEs assist L2 learning by bringing learners' attention to language. We studied the language used in FFEs in a Spanish as a foreign language (SFL) classroom to better understand the pedagogical purposes of L1 use in the classroom. We video-recorded 12 hours…

This study investigated the impact of topic interest, alongside L2 proficiency and gender, on L2 vocabulary acquisition through reading. A repeated-measures design was used with 135 Korean EFL students. Control variables included topic familiarity, prior target-word knowledge, and target-word difficulty (word length, class, and concreteness).…

This study investigated (1) the extent of vocabulary learning through reading and listening to 10 graded readers, and (2) the relationship between vocabulary gain and the frequency and distribution of occurrence of 100 target words in the graded readers. The experimental design expanded on earlier studies that have typically examined incidental…

The present study examines how glossing of second language (L2) texts affects L2 learners' reading comprehension as well as their learning of L2 grammar and vocabulary. It employed a pretest, immediate posttest, and delayed posttest design with two treatment sessions. The target features were English unaccusativity and 10 pseudo-word items.…

This study investigates the roles of collaborative output, the modality of output, and word engagement in vocabulary learning and retention by Chinese-speaking undergraduate EFL learners. The two treatment groups reconstructed a passage that they had read in one of two ways: (1) dyadic oral interaction while producing a written report (Written…
