Exploring the longitudinal development of second language (L2) lexical use has been one of the important topics in L2 vocabulary research. One approach to examining longitudinal changes in L2 lexical use is to capture changes in lexical features as found in learner production, such as L2 writing, over time. To further facilitate this approach, the…

This article explores language learning as the speakers' microlongitudinal project in interaction. Using conversation analysis (CA) as a method, we present a single-case analysis on how a change occurs in the linguistic repertoire of 2 learners of Finnish. We discuss the challenges that the temporal aspect in learning poses within CA, such as the…

Purpose: Elementary-age dual language learners (DLLs) from Spanish-speaking homes in the United States are often characterized as at risk for low vocabulary in both Spanish and English. This longitudinal study examined conceptually scored receptive and expressive vocabulary development among DLLs from Spanish-speaking, low-income homes and…

In the present study, we take a longitudinal, corpus-based perspective to investigate short-term (over 9 months) linguistic change in the language produced for the spoken and written sections of the "TOEFL iBT"® test by a group of English-as-a-foreign-language (EFL) learners in China. The goal of the study is to identify patterns that…

The purpose of this study was to explore the ways emergent bilingual first-graders draw on multiple linguistic resources during reading assessments and the participation of their Spanish-dominant parents in those assessments, as children engaged in English and Spanish retelling tasks. Informed by a translanguaging lens, sociopsycholinguistic and…

Drawing on usage-based linguistics and its exemplar-based path of language learning, from recurring multiword expressions to increasingly abstract, schematized constructions, this article examines evidence for the exemplar-based developmental sequences for yes/no interrogatives and WH interrogatives in English as a second language (L2). The…

In this article the authors report on the use of a scaffolding pedagogy (Gibbons, 2009), informed by systemic functional linguistics, to support the writing of English language learners in middle years curriculum learning. They focus on the work of one teacher and her English class across the first 18 months of a longitudinal design-based literacy…

This multiple case study examines patterns in the oral second language use of three Spanish-speaking English language learners in rehearsed presentations produced annually over 4 years (Grades 9-12) in a U.S. high school. Analysis focuses on students' changing use of transitional devices called frame markers (Hyland, 2005) as a lens for…

Few studies ethnographically detail how Indigenous young people's mobility intersects with sociolinguistic transformation in an interconnected world. Drawing on a decade-long study of youth and language contact, I analyze Yup'ik young people's migration in relation to emerging language ideologies and patterns of language use in "Piniq,"…

This study examines the acquisition of target-like patterns of variation by 22 American learners of French during study abroad (SA) in France and correlates such acquisition with the creation of dense, multiplex, exchange-based social networks (Milroy 1980) with native speakers (NSs) during the SA period. In this longitudinal study, naturalistic…

This chapter presents the results of a study on interlanguage variation. The production of four L2 learners of Italian, tested four times at yearly intervals while engaged in four oral tasks, is compared to that of two native speakers, and analysed with quantitative CAF measures. Thus, time, task type, nativeness, as well as group vs. individual…

This study examines pragmatic differentiation in early trilingual development through a longitudinal analysis of language choice in a developing Tagalog-Spanish-English trilingual child. The child's patterns of language choice with different language users are analyzed at age 1 ; 10 and 2 ; 4 to examine: (1) whether evidence for pragmatic…

The recognition of second language (L2) development as a dynamic process has led to different claims about how language development unfolds, what represents a learner's linguistic system (i.e., interlanguage) at a certain point in time, and how that system changes over time (Verspoor, de Bot, & Lowie, 2011). Responding to de Bot and…

This article deals with the interlanguage of adult second language (L2) learners acquiring finiteness. Due to the inaccessibility of bound inflectional morphology, learners use free morphology to mark a syntactic relationship as well as person and number features separately from the thematic verb, expressed by a pattern like "the man is go".…

This volume collects empirical studies applying Conversation Analysis to situations where second, third and other additional languages are used. A number of different aspects are considered, including how linguistic systems develop over time through social interaction, how participants 'do' language learning and teaching in classroom and everyday…
