To respond to recent calls for examining oral fluency from a broader social and communicative perspective, the current study aimed at investigating the effects of task communicative function on second language (L2) and first language (L1) speakers' fluency. Designing tasks that represent three different communicative functions (congratulations,…

Through the application of the Douglas Fir Group's transdisciplinary framework, this study investigated how three levels of mutually dependent influence (i.e., the micro level of social action and interaction, meso level of sociocultural institutions and communities, and macro level of ideological structures) operate across time and space to shape…

This mixed-methods study explores the efficacy of a multidimensional identity measurement tool that aims to represent the diverse language experiences of heritage language learners (HLLs) and heritage language speakers (HLSs). Drawing on the thematic commonalities across 13 definitions of HLLs, a questionnaire was developed to capture age of…

Framed by family language policy (FLP), in conjunction with the Douglas Fir Group's ecological transdisciplinary framework for second language acquisition, this multiple case study investigates the FLPs of two Hmong-American families in relation to a Hmong-English dual-language program (DLP) where their children are enrolled. Interviews,…

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…

The effects of learner- and task-related variables on second language (L2) writing syntactic complexity (SC) have been extensively investigated. However, previous research has rarely assessed the reliability of computational tools for analyzing the SC of L2 spoken production, and we know less about the effects of such variables on L2 speaking SC.…

This study responds to calls to reexamine the L2 motivational self system framework in order to understand motivations to learn languages other than English. Specifically, we explore Indigenous Taiwanese students' heritage language learning motivation from a possible selves perspective. Following work on the rooted L2 self, the construct of the…

This collaborative autoethnography explores the intersection of heritage language (HL) maintenance, emotion, and identity from the perspectives of a mother and her 15-year-old daughter learning and maintaining Korean in the United States. The analysis of their narratives concerning critical emotional experiences relevant to HL maintenance reveals…

Although intelligibility is a core concept in second language (L2) speech assessment and teaching research, the vast majority of previous work relies on audio-only stimuli. The current study set out to examine how linguistic and visual information jointly interact to determine the degree of speech intelligibility. Both first language (L1) and L2…

The simple view of reading (SVR) model proposes that reading comprehension is the product of cognitive domain skills, word decoding, and oral language (linguistic) comprehension, and that decoding and language comprehension make separate, independent contributions to reading comprehension. The SVR has been supported in both first (L1) and second…

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…

In second language (L2) research, the lexical unit is often defined as a base word plus inflectional and derivational forms through Level 6 of Bauer and Nation's framework (WF6). WF6 use has been justified by the assumption that once a form is known, recognition of other WF6 members requires little extra effort. A more lenient view holds that an…
