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…

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…

The use of students' first language (L1) in additional language (L2) instruction has been a recurring theme in language education research. While research has documented the amount of L1 use and its purposes in L2 instruction, little research has investigated the multifaceted motives that influence language choices at the micro level of social…

The measurement of second language (L2) productive lexical proficiency has driven a great deal of research over the past two decades. Research has indicated that more proficient speakers and writers tend to use a wider range of words and that more proficient writers tend to use words that are more sophisticated (less frequent in reference…

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…

Language learners are often required to negotiate classroom participation in pair and group work; therefore, willingness to communicate (WTC) could be a key determiner of second language (L2) success. Classroom WTC is volatile and influenced by interlocutor-related variables, such as reciprocal identities, group membership and atmosphere, and peer…

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…

Concept-based language instruction (C-BLI) is a pedagogy guided by sociocultural theory, which has been shown to be effective in facilitating second language learning. Typical activities include materialization by using a schema for a complete orienting basis of an action (SCOBA) and languaging, through which learners' internalization of…

This article presents selected results from a large-scale, mixed-methods, federally funded investigation of US-based language study-abroad alumni of all ages, which included a nationwide survey (N = 4,899) followed by professional life history interviews with 54 participants. Here, we focus on three questions heretofore unaddressed: (a) How do…

This article theorizes translanguaging as a space of simultaneity to analyze how teachers use translanguaging to create a multilingual classroom space and engage students with their multilingual identities and epistemologies in the classroom. The data in this article are drawn from an ethnographic study of language policies and practices in a…

This study explored the role of feedback-seeking behaviors (FSB) in how English-as-a-second language (ESL) learners benefit from written corrective feedback (WCF). Seventy-six learners enrolled in an ESL writing course at a major university in the United States completed an FSB questionnaire, wrote a narrative essay, received WCF on their essays,…

This study investigates a second language (L2) speaker's use and learning of the Icelandic auxiliary verb "aetla" (pronounced /aihtla/) in the wild. This analytic focus is motivated by the L2 speaker's (Anna) own orientation to "aetla" as a learnable. We track Anna's use of "aetla" in naturally occurring social…

This study explores the lexical profile of essays written by 48 advanced learners of second language (L2) Russian who participated in the Russian Overseas Flagship, an intensive year-long study abroad program designed to help students reach Interagency Language Roundtable (ILR) Level 3 proficiency in all skills. Using the lexical frequency profile…

The present study takes a variationist perspective to explore the varietal repertoires of adult learners of German as a second language (L2), that is, their variable use of standard German, Austro-Bavarian dialect, and mixture varieties. Forty L2 learners completed a virtual reality task involving interactions with dialect-speaking and…

Emotions in foreign language (FL) learning have become an increasingly popular research avenue in applied linguistics. Such research is often carried out using linear correlational or regression methods, which are limited in the extent to which they can depict interrelations. In this study, we aimed to reexamine the relationships between the…
