The current study is an attempt to investigate the particular role learners' vocabulary knowledge plays in their reading comprehension performance. It intends to determine whether breadth and depth of vocabulary knowledge are related to EFL learners' reading comprehension, and to investigate which one of these variables, that is, depth or breadth of vocabulary knowledge, makes a more important ...

Abstract This meta-analysis examines the effectiveness of technology-assisted second language (L2) vocabulary learning as well identifies factors that may play a role in their effectiveness. We found 34 studies with 2,511 participants yielding 49 separate effect sizes. Following procedure developed by Hunter and Schmidt (2004), we corrected for sample size bias measurement error. The overall us...

Provision of multiple-choice (MC) glosses, which combines the advantages of glosses and inferring, has recently gained its share of supporters as a potential technique for enhancing L2 texts and increasing word gain for L2 learners. Upon taking an actual TOEFL, the participants underwent a vocabulary pretest to ensure that the target words were unfamiliar to all of them. Half of the participant...

The present study addresses a long-standing assumption in the field of applied linguistics: that presenting new second language (L2) vocabulary in semantically grouped sets is an effective method of teaching. Participants learned 32 new L2 labels for concepts from four different semantic categories in either a related or unrelated condition. At test, participants translated words in both transl...

This study sought to investigate the effect of teacher codeswitching, as compared to monolingual (L2) instruction, on L2 vocabulary learning and retention. Though a sizeable body of research on teacher beliefs and behavior regarding classroom L1 use has diminished the efficacy of monolingual pedagogy, the potential of strategic codeswitching for facilitating L2 learning has only recently come u...

This study aims at investigating the effect of dynamic assessment (DA) on L2 writing achievement if applied via blogging as a Web 2.0 tool, as well as examining which pattern of interaction is more conducive to learning in such an environment. The results of the study indicate that using weblogs to provide mediation contributes to the enhancement of the overall writing performance, vocabulary a...

In our modern technological world, Computer-Assisted Language learning (CALL) is a new realm towards learning a language in general, and learning L2 vocabulary in particular. It is assumed that the use of multimedia annotations promotes language learners’ vocabulary acquisition. Therefore, this study set out to investigate the effects of different multimedia annotations (still picture annotati ...
