Use this unique volume to transform the learning and teaching of language so that all students are empowered to succeed. This book offers insight into how to teach language--a core component of developing skilled readers and writers across all content areas--in ways that value the rich and diverse language assets students bring to the classroom.…

Third language (L3) lexical acquisition is still underexplored. In this article I overview theoretical and empirical evidence on L3 lexical acquisition and the role of cross-linguistic influence (CLI) in learning L3 words. I explain the mechanism of CLI as resulting from language co-activation in the multilingual learner's/user's mind.…

This paper provides fresh insights on how PIs (Polarity Items) in non-veridical contexts (questions and conditionals) are represented in the grammar of multilingual learners of Catalan at different stages of development. It explores how this non-native grammatical system interacts with other previously acquired systems of negation and the implicit…

The science of reading (SOR) refers to the sum of what we know about how people learn to read based on empirical studies across multiple disciplines. The purpose of this review was to identify research evidence to inform the SOR for multilingual learners (MLs). We reviewed 30 systematic reviews related to reading and reading instruction for MLs…

Westergaard (2021) presents an updated account of the Linguistic Proximity Model and the micro-cue approach to the parser as an acquisition device. The property-by-property view of transfer inherent in this approach contrasts with other influential models that assume that third language (L3) acquisition involves the creation of a full copy of only…

The purpose of this qualitative research study is to portray the complex language practices of multilingual children when learning mathematics. To do so, I draw on data collected as part of a three-year research study that was designed to understand the relationship between young children's language use and mathematics learning, focusing on…

This provocative article raises many important issues that need to be addressed and in so doing will advance the fields of second language (L2) and third language (L3) acquisition in several important ways. Fundamental questions concerning multilingual development persist especially with respect to the role of Universal Grammar in this language…

In this commentary to Westergaard (2021), we focus on two main questions. The first, and most important, is what type of L3 data may be construed as supporting evidence--as opposed to a compatible outcome--for the Linguistic Proximity Model. In this regard, we highlight a number of areas in which it remains difficult to derive testable predictions…

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…

This research compares the use of triadic dialogue and translanguaging in two multilingual grade seven classrooms where algebra is taught in a foreign language. Ten lessons in one classroom that involve teaching properties and seven lessons in another classroom that involve teaching conventions were video- and audio-recoded and then transcribed.…

Using data from multilingual settings in universities and adjacent learning contexts in East Asia, North Africa, Central and North America and Europe, this book provides examples of the heuristic value of translanguaging and epistemological decentring. Despite this and other theoretical and empirical work, and ever stronger calls for the inclusion…

This paper presents insights from two interview studies with the aim of shedding light on the learning potential of studying abroad in an area where English is used as a lingua franca. The majority of previous research on study abroad focuses on students' experiences of studying abroad in target-language regions, for example learners of English…

Saussure proposed the division language/parole and argued that language can be studied as a formal system. Fifty years later Chomsky declared competence the core interest of linguistics. Although for years Generative second language acquisition (GenSLA) has adopted this view, a number of recent publications poke holes into the competence bubble.…

In her keynote article advocating the Linguistic Proximity Model for third language (L3) acquisition, Westergaard (2021) presents several arguments against 'copying and restructuring' in nonnative language acquisition, mechanisms central to Schwartz and Sprouse's (1996) Full Transfer/Full Access model of second language (L2) acquisition. In this…

This commentary discusses the recent keynote article in "Second Language Research" by Westergaard (2021), which extends the Micro-cue Model to second language (L2) and third language (L3) acquisition. The commentary comments on such questions as: What makes a given property easy or hard to acquire? How do learners determine similarity?…
