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…

Second language acquisition (SLA) research offers valuable insight on how languages are learned and how they coexist and influence each other. Sign language learners offer unique perspectives on SLA, allowing researchers to test theories that are otherwise constrained by access to only one modality. Current literature on sign language learning…

Language is subject to a variety of pressures. Recent work has documented that many aspects of language structure have properties that appear to be shaped by biases for the efficient communication of semantic meaning. Other work has investigated the role of social pressures, whereby linguistic variants can acquire positive or negative evaluation…

To date, there has been mounting research evidence on the impact of written corrective feedback. In response to this, reviews have been conducted to condense either findings or methodologies through the combined analysis of EFL and ESL studies. Although syntheses shed light on the topic, no one provides exclusive insights into EFL realities.…

How people conceptualize learning is related to real-world educational consequences across many domains of education. Despite its centrality to the educational system, we know little about how the public reasons about language acquisition, and the potential consequences for their thinking about real-world issues (e.g., policy endorsements). The…

The construct "awareness" is undoubtedly one of the more difficult constructs to operationalize and measure in both second language acquisition (SLA) and non-SLA fields of research. Indeed, the multifaceted nature of awareness is clearly exemplified in concepts that include perception, detection, and noticing, and also in type of…

Immersion programs have long been considered the gold standard for school-based language revitalization, but surprisingly little attention has been paid to the quantity and quality of the input that they provide to young language learners. Drawing on new data from three such programs (Kaqchikel, Western Subanon, and Maori), each with its own…

The phenomenon of regularization -- learners imposing systematicity on inconsistent variation in language input -- is complex. Studies show that children are more likely to regularize than adults, but adults will also regularize under certain circumstances. Exactly why we see the pattern of behaviour that we do is not well understood, however.…

Synonymy is important but difficult for language learners to grasp. Using a forced-choice question instrument, along with corpus data as reference, this study examines the use of four sets of synonyms by intermediate/advanced Chinese EFL/ESL learners and native English speakers. The data analyses reveal several key findings, including a general…

This contribution examines how the diverse language resources that teachers and learners bring to the classroom can support the process of language learning. It draws on a range of linguistic ethnographic data collected at a French language course that was attended mostly by Syrian and Iraqi refugees in Luxembourg. Drawing on the analysis of…

Rising enrollments of students for whom English is not a first language mean that every teacher -- whether teaching kindergarten or high school algebra -- is a language teacher. This book explains what teachers need to know about language in order to be more effective in the classroom, and it shows how teacher education might help them gain that…

This article examines the Multiple Grammars (MG) theory proposed by Luiz Amaral and Tom Roeper in the present issue and presents a critique of the research that went into the theory. Topics discussed include the allegation that the bilinguals and second language learners in the original article are primarily students in an academic setting, Amaral…

Second language (L2) learners of tone languages do not perceive and produce the different tones of the target language with equal ease. The most common explanation for these asymmetries is that acoustically salient tones are the easiest to learn. An alternative explanation is that tones are easiest to learn when they are highly frequent in the…

This article puts forward a solution to the impending shortage of culturally and linguistically competent interpreters: the education of heritage signers as heritage language learners. It examines the current landscape of American Sign Language (ASL) as a course of study and the difficulties heritage signers report when they begin learning ASL. In…

Providing a comprehensive survey of cutting-edge work on second language learning, this "Handbook," written by a team of leading experts, surveys the nature of second language learning and its implications for teaching. Prominent theories and methods from linguistics, psycholinguistics, processing-based, and cognitive approaches are…
