To determine the effects of explicit instruction (EI) and potential moderators in second/foreign language (L2) teaching, this study meta-analyzed 28 primary reports (a total of 67 unique samples, N = 3754). The main results show that EI was significantly effective in facilitating L2 development, with effect sizes ranging from moderate to large…

Although explicit instruction is effective in helping second language (L2) learners develop intelligible pronunciation, it is necessary to understand why and how L2 teachers implement such explicit pronunciation instruction systematically in class. Because of its key role in enhancing learners' pronunciation skills, understanding the rationale…

An important issue in second-language acquisition concerns the role of explicit information (EI) and how it is affected by individual differences. The present study explored this question through a partial replication and extension of Fernández (2008: Experiment 2), which investigated the effects of EI in processing instruction (PI) for the…

The debate between effectiveness of explicit and implicit teaching has taken a center stage in the second language acquisition literature over a long period of time. Most of such debates center on grammar teaching and very few discuss suprasegmental features especially, syllable structure. All languages have some sort of syllabicity; however, the…

This study investigates the effects of instruction on second language (L2) pragmatic competence and the factors that moderate the effectiveness of pragmatics instruction. A comprehensive literature search yielded 29 primary studies that involved 1,898 L2 learners, generating 54 effect sizes for between-group contrasts. Aggregated results showed…

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…

At some upper secondary schools in Sweden, newly arrived migrant youths can attend vocational courses while studying in the language introduction programme. The teaching practices in relation to language learning for newly arrived migrant students in this kind of school-based VET and how these practices are conditioned are investigated in the…

The present study examines the impact of the explicitness of corrective feedback and explicit associative memory on the acquisition of -ing/-ed participial adjectives through delayed video-based corrective feedback. Fifty-two L1 Spanish learners were randomly assigned to one of three groups (implicit, explicit, or no-feedback) and performed an…

A great deal of research explores how implicit vs. explicit instruction affects second language learners' grammatical accuracy, generally finding that explicit instruction increases accuracy. However, no research to date has examined the impact of implicit/explicit instruction on learners' fluency. Additionally, nearly all the research has only…

Investigations of crosslinguistic effects in second language acquisition (SLA) have contributed rich understandings about the ways in which prior language knowledge and experience can influence additional language learning. Building on this work, one recent line of research has examined the extent to which SLA findings about crosslinguistic…

Purposeful and strategic use of L1 can help with L2 learning. However, in many contexts, monolingual immersion approaches dominate, leading language teachers to refrain from using L1. It can also mean that teachers are not professionally prepared to implement evidence-informed uses of L1. In this article, we share the findings of an intervention…

In Thailand, the traditional teaching approach used for English language classes has been to explicitly teach English grammar, but in recent years the strategy has begun to shift towards the implicit teaching of language via communicative techniques. Within academic circles, there has been minimal agreement on the suitability of approaches used.…

With the growing number of non-native English speakers, improving communication through direct vocabulary instruction (DVI) is important. The problem investigated in this study was that English as a second language (ESL) teachers were not using the strategy DVI, in the ESL classroom. The purpose of this basic qualitative study was to explore ESL…

Following the social turn in Second Language Acquisition (SLA) in the 1990s (Block, 2003), researchers have increasingly focused on the emic perspective of learners. As a result, identity, subjectivity, and agency have come to the forefront in SLA research. In an effort to afford learners the means to negotiate meaning more freely and to position…

The current study explores the short- and long-term impacts of explicit reading strategy instruction for improving reading comprehension of students with different learning styles. Sixty Iranian EFL learners took part in this study. They took the Cambridge ECCE reading test as the pre-test and were divided into five groups according to learner…
