Increased second language acquisition (SLA) research interest in the effect of planning on subsequent L2 oral production has typically examined the effect of planning on the syntactic complexity, accuracy, lexical complexity, and/or fluency (CALF) of L2 production. However, the results of research in this domain are inconclusive. This study, a…

This study investigates the impact of Filipina domestic workers (FilDWs), a marginalized group in Hong Kong (HK), on HK children's language development. It focusses on FilDWs' influence on the second language (L2) English of bilingual HK primary school children attending an English Medium of Instruction school. The elements investigated are L2…

A great deal of research explores how implicit vs. explicit instruction affects second language learners' grammatical accuracy, generally finding that explicit instruction increases accuracy. However, no research to date has examined the impact of implicit/explicit instruction on learners' fluency. Additionally, nearly all the research has only…

This study investigates the differential effects of a task-based inside-school intervention and an outside-school project intervention on the development of speaking skills of 56 beginner second language (L2)-learners. The study extends previous research by looking at development across multiple occasions instead of two (i.e., a pretest and…

A challenge of large-scale oral communication assessments is to feasibly assess a broad construct that includes interactional competence. One possible approach in addressing this challenge is to use a spoken dialog system (SDS), with the computer acting as a peer to elicit a ratable speech sample. With this aim, an SDS was built and four trained…

Does a native language suffer when students take all of their classes in a foreign language, even in their home country? Turkish students studying psychology, economics, or English literature with English as the language of instruction (N = 91) were studied across a three-year period. Test scores, word fluency measures, and self-ratings were…

This study investigates how the use of discourse markers reflects speaking fluency in Chinese learners. In this study, 220 min of online Chinese courses were transcribed, with 17 Chinese learners and 5 native Chinese teachers as participants. Half of the transcribed data were drawn from students living in Taipei, Taiwan, a Chinese-speaking…

This article reports results of a longitudinal study of vocabulary breadth knowledge growth, vocabulary fluency development, and the relationship between the two. We administered two versions of the Vocabulary Levels Test (VLT; Nation 1983; Nation 1990; Schmitt et al. 2001) to 300 students at a Chinese university at three different time points…

This article explores attitudes and response to language selection in advertising targeting Italian bilinguals who belong to a defined speech community. The research builds upon (i) research on multilingual advertising by investigating its attitudinal correlates, and (ii) studies on advertising to bilinguals through the verification of the…

Communicative adequacy is a key construct in second language research, as the primary goal of most language learners is to communicate successfully in real-world situations. Nevertheless, little is known about what linguistic features contribute to communicatively adequate speech. This study fills this gap by investigating the extent to which…

This longitudinal case study follows a dynamic systems approach to investigate an under-studied research area in second language acquisition, the development of complexity and accuracy for an advanced untutored learner of English. Using the analytical tools of dynamic systems theory (Verspoor et al. 2011) within the framework of complexity,…

The study reported in this article investigated the proficiency in French of a group of anglophone adult L2 learners of the language, all of whom reported passing regularly for native speakers of French. Tests were administered to these learners to gauge their proficiency in different aspects of French, including a lexico-grammatical measure. A…

The present study focuses on the influence of starting age and input on foreign language learning. In relation to starting age, the study investigates whether early starters in instructional settings achieve the same kind of long-term advantage as learners in naturalistic settings and it complements previous research by using data from oral…

This study provides an empirically based contribution to the growing body of research using conversation analysis as a methodical tool for analysing functions of action types through interaction in L2 classroom settings. Using data from various L2 classrooms in ESL and EFL contexts, it is argued that the role of repeats differ depending on the…

It is a good practice to try to understand matters at hand by first stepping back and adopting an historical perspective, which I will begin this review by doing. Next, I will take up the challenges that each of the authors in the articles in this volume has presented for the study of complexity, accuracy, and fluency (CAF) in second language…
