Abstract This study reports on the results of a meta-analysis which investigates the effects of dictionary use on second language (L2) vocabulary acquisition, as well as the magnitude of the moderating effect of a number of moderator variables on the effectiveness of dictionary use in improving L2 vocabulary knowledge. A total of 125 effect sizes were gleaned from 44 studies, which represented 87 independent samples and included 3,475 participants. A random-effects model of the meta-analysis shows that the overall effect of dictionary use on L2 vocabulary acquisition is g = 2.10 (p < .01) for within-group studies and g = 1.03 (p < .01) for between-group studies respectively, which are both large in the domain of second language research. Subsequent moderator variable analysis reveals how treatment-related variables (timepoint, dictionary form, dictionary type, target lexical unit, vocabulary knowledge type, learning condition, and research setting), methodological variables (type of experimental design, presence of pretest, and assessment type), as well as learner-related variables (age and proficiency) might contribute to the variation across studies. Implications of the findings are discussed.

L2 Vocabulary

Despite the growing interest in incorporating textual glosses into second language (L2) reading in hypermedia and paper media, no agreements have been reached as to whether and what extent a textual gloss facilitates L2 learners’ vocabulary acquisition in hypermedia and paper media. The present study meta-analysed the overall effects of textual glosses and different glossing types (i.e. language, location, and mode) on L2 vocabulary acquisition, as well as the moderation effects on the variability of L2 vocabulary acquisition effect sizes. Based on a comprehensive search, 20 studies involving 2,291 participants that have quantitatively documented the changes of L2 vocabulary gains through a pre-and-post textual glosses design were identified and coded in order to retrieve moderator variables. The results show the following: (1) textual glossing has a medium effect on L2 vocabulary acquisition; (2) the effect of textual glosses on L2 vocabulary acquisition persists over time; (3) glossing location and glossing mode significantly impact the effect of textual glosses on L2 vocabulary acquisition but glossing language has no definite effect; and (4) outcome measure is the only moderator variable among the three influencing factors on vocabulary acquisition. These results are further discussed with reference to existing studies and theory of second language acquisition.

Abstract This study investigates the effects of corpus use on second language (L2) vocabulary learning as well as the influence of moderators on effectiveness. Based on 29 studies representing 38 unique samples, all of which met several criteria for inclusion (e.g. with control groups), we found an overall positive medium-sized effect of corpus use on L2 vocabulary learning for both short-term (77 posttest effect sizes; Hedges’ g = 0.74, SE = 0.09, p < .001) and long-term periods (34 follow-up effect sizes; Hedges’ g = 0.64, SE = 0.17, p < .001). Furthermore, large variation in adjusted mean effect sizes across moderators was revealed. Above all, for the different dimensions of L2 vocabulary knowledge, in-depth knowledge (i.e. referential meanings as well as syntactic features of vocabulary) was associated with a large effect size. Moreover, the results revealed that learners’ L2 proficiency and several features of corpus use (i.e. interaction types, corpus types, training, and duration) influence the magnitude of the effectiveness of corpus use in improving L2 vocabulary learning.

L2 Vocabulary

Vocabulary development is indisputably a vital aspect of second language acquisition. In spite of the abundant attention it has garnered over the past few decades, it remains unclear how adult learners fare with intentional and incidental ways of learning. The current study investigated the effects of intentional learning (via studying a word list), incidental learning (via reading), and combined intentional-andincidental learning (via studying a word list followed by reading) conditions on 30 adult learners’ second language vocabulary acquisition. Vocabulary acquisition was measured in terms of percentage gains as well as changes in the depth of vocabulary knowledge. Results showed that while both the intentional and incidental modes of learning led to vocabulary gains, the combined intentional-and-incidental condition resulted in significantly greater gains than either the intentional-only or the incidentalonly condition. No significant differences were found between the incidental-only and intentional-only conditions.

Substantial Extent

In second language (L2) vocabulary acquisition, breadth and depth of vocabulary knowledge are two indispensable components that interrelate with each other to a substantial extent. Breadth of vocabulary is actually vocabulary size. Lexical sense relations, part and parcel of depth of vocabulary, are reported to be able to facilitate the mastery of L2 words. Word frequency concerns the familiarity of words. The present research intends to make a synthetical analysis of the development of L2 word meaning under the influence of vocabulary size and word frequency in classroom settings. The merging of qualitative and quantitative aspects of words is to describe exhaustively how students fit the words into their mind, and to provide some pedagogical implications to L2 vocabulary teaching and learning.

ABSTRACTWe examined to what extent the variation in vocabulary learning outcomes (vocabulary knowledge, learning gain, and rate of forgetting) in English as a second language (L2) in context can be predicted from semantic contextual support, word characteristics (cognate status, Levenshtein distance, word frequency, and word length), and student characteristics (prior vocabulary knowledge, reading ability, and exposure to English) in 197 Dutch adolescents. Students were taught cognates, false friends, and control words through judging sentences with varying degrees of semantic contextual support using a pretest/posttest between subjects design. Participants were presented with an English target word and its Dutch translation, followed by an English sentence. They were instructed to judge the plausibility of the sentence. Mixed-efffects models indicated that learning gains were higher for sentences with more semantic contextual support and in students with stronger reading comprehension skills. We were the first to show that Levenshtein distance is an important predictor for L2 vocabulary learning outcomes. Furthermore, more accurate as well as faster learning task performance lead to higher learning outcomes. It can thus be concluded that L2 study materials containing semantically supportive contexts and that focus on words with little L1-L2 overlap are most effective for L2 vocabulary learning.

Since its inception, the field of second language research has utilized methods from a number of areas, including general linguistics, psychology, education, sociology, anthropology and, recently, neuroscience and corpus linguistics. As the questions and objectives expand, researchers are increasingly pushing methodological boundaries to gain a clearer picture of second language learning. At one end for example, we see measures of cognition (e.g., brain imaging and eye tracking) and at the other end we see exploration of issues of culture and identity (e.g., ethnographies, deep dive case studies, introspective and narrative analyses). There is an emerging emphasis on research synthesis, meta-analysis, and replication. This article illustrates a few of the advancements in methods and research agendas in SLA. I will conclude by highlighting some of the ways that second language researchers can continue to incorporate, assimilate, and shape methodology, as well as pointing out some of the potential pitfalls, and overall, how these methodological innovations benefit the field.

Applied linguists are increasingly conducting meta-analysis in their substantive domains, because as a quantitative approach for averaging effect sizes across studies, it is more systematic and replicable than traditional, qualitative literature reviews. Additional strengths, such as increased statistical power, moderator analyses, and model testing, have also contributed to its appeal. The current review describes typical stages of a meta-analysis in second language acquisition (SLA) research: (a) defining the research domain, (b) developing a reliable coding scheme, (c) analyzing data, and (d) interpreting results. Each stage has a host of equally reasonable decisions that can be made; each decision will influence the conduct of the meta-analysis, the nature of the results, and the substantive implications of findings for SLA. We highlight a number of benefits and challenges that inform these decisions. In general, when a meta-analysis in applied linguistics is well planned, employs sound statistical methods, and is based on a thorough understanding of relevant theory, it can provide critical information that informs theory as well as future research, practice, and policy.

ABSTRACTThis study examined the role of phonological memory in second language (L2) grammar learning in a group of native French-speaking children undergoing a 5-month intensive English program. Phonological memory (as referenced by Arabic [ANWR] and English [ENWR] nonword repetition tasks), L2 vocabulary (receptive and productive vocabulary knowledge), and L2 grammar (knowledge of morphosyntactic structures) were assessed during the first (Time 1) and last (Time 2) month of the program. After controlling for initial grammar ability, phonological memory significantly predicted grammar development (27.9% of variance explained) in addition to the contribution made by vocabulary knowledge (9.5% of variance explained). Although phonological memory ability as measured by ENWR increased between Time 1 and Time 2, ANWR did not improve. The findings show that phonological memory plays an important role in L2 grammar development that is unmediated by lexical knowledge. They also provide evidence that phonological memory improves with language development, but that basic phonological memory capacity (as measured by ANWR in this study) remains unchanged over time.
