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.…

Glossing is a widely used and examined vocabulary learning tool, and one of the major branches of glossing research has compared the relative effects of first language (L1) and second language (L2) glosses on reading comprehension and vocabulary learning. However, the findings in this literature have not been consistent, calling for a…

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 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…

The current study examined the effects of first language (L1) textual and audio glosses along with the moderating effect of learners' visual and auditory perceptual style on second language (L2) vocabulary learning. The participants were first divided into two groups of auditory and visual learners based on their scores obtained from a learning…

Although repeated reading--a pedagogical practice often involving phonological support in which learners revisit novel forms in context--has been extensively studied in terms of reading fluency and comprehension, little research has explored whether it promotes language acquisition. The current study, an attempt to fill this gap, found that…

The current study investigated the effects of three forms of output activity on EFL learners' recognition and recall of second language (L2) vocabulary. To this end, three groups of learners of English as a foreign language (EFL) were instructed to employ the following three output activities after reading two narrative texts: (1) summarizing the…

Research to date suggests that textual enhancement may positively affect the learning of multiword combinations known as collocations, but may impair recall of unenhanced text. However, the attentional mechanisms underlying such effects remain unclear. In this study, 38 undergraduate students were divided into two groups: one read a text…

We examined how learning new second language (L2) words was affected by three "task type" conditions (reading only, reading with a dictionary, reading and word focused exercises), three "number of encounters" conditions and their combinations. Three groups of L2 learners (n = 185) were exposed to 30 target words (one group in…

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…

Many studies have shown that reading can have a beneficial effect on second language learning, but relatively few of these have focused on extensive reading in classroom environments over a period of time. This study compares an extensive reading class against a more traditional class involving intensive reading and vocabulary exercises. The…

This study tests the claim that word learning and retention in a second language are contingent upon a task's involvement load (i.e. the amount of need, search, and evaluation it imposes), as proposed by Laufer and Hulstijn (2001). Seventy-nine beginning learners of Spanish completed one of three vocabulary learning tasks that varied in the amount…
