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…

Although core in the teaching of academic language skills, little research to date has investigated what makes video-recorded lectures difficult for language learners. As part of a larger program to develop automated videotext complexity measures, this study reports on selected dimensions of linguistic complexity to understand how they contribute…

Flow is an intrinsic motivational state associated with full task engagement, positive affect, and enhanced performance. While research has examined how different language tasks interact with flow experiences, no study has examined learner flow experiences in a wide range of tasks using an experience sampling method to determine how universal…

Although most children learn to communicate in their first language (L1), there is normal and expected variation in their rate of acquisition across all components of the language system. Until recently, most second language acquisition and second language (L2) researchers have assumed that individual differences (IDs) in L1 acquisition are small…

Empirical research on the relationship between language learners' (LLs') multilingual and professional development has remained scant in conversations surrounding LLs' sustained engagement with a target language (TL) beyond higher education. To address this gap, this article examines the co-construction of US collegiate LLs'…

For L2 learners from English-dominant societies, study abroad (SA) is an especially significant opportunity for linguistic, sociocultural, and personal development. Less is known about the durability of these SA-related developments, once Anglophone language specialists complete their home studies and then progress to graduate careers. This…

The present study investigates to what extent first-language (L1) and second-language (L2) speakers use lexical futures, whether such forms provide evidence of development, and whether these forms are constrained differently from the present indicative (PI) according to linguistic predictors. It uses a combined approach through its…

Addressing themes from the Douglas Fir Group's (2016) transdisciplinary framework, this paper bridges boundaries between cognitive and social disciplines by showing how social contextual factors can affect the psycholinguistic development of complexity, accuracy, and fluency (CAF) in learner language. Sociolinguistic and sociocultural frameworks…

A unique anxiety for foreign language (L2) learning has been hypothesized to explain students' problems with language learning. However, L2 anxiety instruments have been challenged on the grounds that they reflect students' language learning ability and/or perceptions of their language learning skills. In this study, 266 U.S. high school students…

This study investigated second language fluency development over a nearly 2-year period which included an academic year abroad and the year immediately following the participants' return to their home university. Data from 24 L1 English learners of Spanish were collected 6 times: once before, 3 times during, and 2 times after a 9-month stay…

Some people ascribe successful language learning to an innate aptitude that cannot be further developed, at least after a certain young age (i.e., an entity mindset), while other people believe that language learning ability can be improved (i.e., an incremental mindset). The purpose of this research is to (a) introduce the Language Mindsets…

Bilingual classrooms most often have strict language arrangements about when and who should speak what language to whom. This practice responds to diglossic arrangements and models of bilingualism developed in the 20th century. However, in the 21st century, heteroglossic bilingual conceptualizations are needed in which the complex discursive…

A factor analysis of a test battery that included early first-language (L1) achievement, L1 cognitive ability, second-language (L2) aptitude, and L2 affective measures to predict oral and written L2 proficiency was conducted. The analysis yielded 4 factors that were labeled Language Analysis, composed of L1 and L2 language comprehension, grammar,…

In this contribution, some of the basic characteristics of complex adaptive systems, collectively labeled Dynamic Systems Theory (DST), are discussed. Such systems are self-organizing, dependent on initial conditions, sometimes chaotic, and they show emergent properties. The focus in DST is on development over time. Language is seen as a dynamic…

Computer-assisted language learning (CALL) literature notes concerns with research in the field, and many of these concerns are similar to those noted for second language acquisition research in general. One fundamental problem is the general failure to address Garrett's (1991) assertion that research must consider classroom context. We believe…
