Drawing on positioning theory and Vygotsky's sociocultural theory of mind, this study analyzes the discursive processes through which expert and novice positions are negotiated in heritage-second language (HL-L2) learner interaction. It examines how positioning practices shape collaboration between HL and L2 learners, determining what types of…

Chinese immersion programs have been increasingly popular in US schools. However, we have insufficient data on young English-speaking children's acquisition of Chinese as a second language in these programs, and specifically on social contextual variables systematically promoting or hindering Chinese language use. Taking a variationist…

In many language classrooms in multilingual nations, standard dialects are associated with and promoted in formal domains. Through classroom pedagogical processes that reify standard language use, other dialects are relegated to informal domains and therefore devalued in classroom settings. Informed by critical pedagogy, this article challenges…

Heritage language (HL) learning is often facilitated by consistent exposure to the HL in family language policy (FLP). However, when children develop a preference for the majority language, family members may negotiate their use of both languages to establish a stronger emotional bond with their children while providing rich HL input. This article…

For many children in Flanders, Belgium, the language of instruction is not their first language. Allowing children to use their heritage languages in the classroom has been argued to have functional and socioemotional benefits. In two exploratory studies, we introduced a multilingual task in four classrooms across three linguistically and socially…

Sociocognitive theory views learning, including second language acquisition, as the progressive "alignment" of individuals vis-à-vis their ecosocial environments. In this article we first update sociocognitive theory in light of recent evolutionary/ecological research on learning/teaching: (a) Humans are evolutionarily "adapted to…

Current quantitative methods in second language (L2) acquisition have proven useful in examining how phraseological unit production changes over time. However, these methods are limited in that they do not allow for the analysis of individual differences in those changes. This study demonstrates the potential for Latent Curve Modeling, a type of…

Within the framework of Conversation Analysis for Second Language Acquisition (CA-SLA), this study uses learning behavior tracking (LBT) (Markee, 2008) with longitudinal data to investigate word learning by one adult second language (L2) user of English. The adult is a first language (L1) user of Japanese with limited proficiency in English. Data…

Research on multilingual acquisition has investigated various combinations of languages to identify the factors determining how learners express motion. Our research examines the semantics of motion expression in learners whose first language (L1) exhibits more variation than their foreign language (L2/L3). The present study compares upward motion…

The aim of this article is to show that the use of Spanish grammatical aspect is biased by inherent aspect depending on the learner's first language (L1). It considers both the Lexical Aspect Hypothesis (LAH; Andersen, 1986, and his followers) and the L1 Transfer Hypothesis (Izquierdo & Collins, 2008; McManus, 2015), and it compares the use of…

The African Storybook (ASb) is a digital initiative that promotes multilingual literacy for African children by providing openly licenced children's stories in multiple African languages, as well as English, French, and Portuguese. Based on Darvin and Norton's (2015) model of identity and investment, and drawing on the Douglas Fir Group's (2016)…

In this study, we explored how major theoretical principles and concepts in the mediation strategies of Vygotsky's sociocultural theory are realized in an Arabic-Hebrew preschool in Israel. The aim of this study was to examine how teachers encourage children to use their second language (L2) during teacher-child conversations. In particular, as a…

This study investigates relations between second language (L2) lexical input and output in terms of word information properties (i.e., lexical salience; Ellis, 2006a). The data for this study come from a longitudinal corpus of naturalistic spoken data between L2 learners and first language (L1) interlocutors collected over a year's time. The…

This study investigates contextual features surrounding the use of a first language (L1) in a Japanese university English-as-a-foreign-language (EFL) course during peer interaction in the extended preparation phase leading up to two oral presentation tasks (OP1 and OP3), performed seven months apart. Interaction data were analysed in terms of the…

This article reports analysis of data collected from a quasi-experimental study in 2 Canadian late French immersion science classes. We examine if, how, and when the first language (L1) is used when students in the first years of their second language learning talk about complex science concepts. We compare differences in groups following a…
