In this final article in this guest-edited issue on synergies in second language acquisition and teaching (SLA/T), we attempt to bring together the main content of this issue in an overall, combined synergy statement, concluding this project as a whole. Let us remind readers of the project: A shared effort by 17 scholars taking 11 different…

The purpose of this article is to examine the ethical tensions and considerations that arise in the world language classroom from using pedagogies of discomfort. Although pedagogies of discomfort have mostly been seen through a positive lens in the literature for engaging students with difficult issues in the classroom, there are ethical concerns,…

This study investigates issues related to race and racialization among Chinese language teachers in US primary and secondary (K-12) schools. Although race is an increasingly important topic in the field of language education, the published research continues to be dominated by the teaching and learning of English as a second language. Set mostly…

Although current approaches to second language (L2) pronunciation underscore that instruction should concentrate on pronunciation features that help learners be more intelligible (and not necessarily more native like), there is little empirical evidence as to what those features are, especially in languages other than English. To address this gap,…

The articles in this special issue contribute to understanding the interactional grounding of language learning by scrutinizing how patterns of language use emerge and get routinized as dynamic resources for accomplishing actions in co-constructed interaction. Their findings problematize how grammar is represented in second language (L2) teaching…

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 study examined the effects of spaced practice on second language (L2) vocabulary learning under different learning conditions. One hundred fifty Korean learners of L2 English were divided into five groups: one control (no treatment) and four experimental groups based on learning condition (fill-in-the-blanks vs. flashcards) and spacing type…

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…

There are calls for developing ways to teach language that can inspire and motivate students to study additional languages. While previous research has pointed toward benefits of arts-based activities in language learning, combining language and dance has mainly been studied with younger language learners. Contextualized within the course…

This study explores the identity formation of two postsecondary language teachers and course coordinators--one in German and one in French--as they created intermediate-level, content-based social justice curricular units for a multiyear project. Using a multiple-case-study methodology and cultural--historical activity theory, this qualitative…

Second language (L2) learners stand to gain substantially from mastering a wide range of multiword expressions (MWEs), and several studies have examined the benefits of language courses that regularly draw learners' attention to MWEs. However, most of these studies focused on the learners' retention of the MWEs included in the course materials and…

With a forward-looking and problem-solving mindset, this article aims to combine theoretical knowledge and empirical evidence from different schools of thought in the field of second language (L2) learning and teaching--namely, instructed second language acquisition, generative linguistics, and an ecological perspective that includes multiple…

This complex article has six subsections. Following a brief introduction, one team of three co-authors and three single authors present compact statements of their distinctive individual research perspectives on second language acquisition and teaching (SLA/T): Atkinson, Mejía-Laguna, and Ribeiro offer a sociocognitive perspective; Cappellini…

The present study involved the analysis of 81 second language instructed vocabulary acquisition (L2 IVA) studies over 2 phases. In Phase I, we categorized and coded the effect sizes of the studies. Observing that the basic between- and within-subject design dichotomy lacked the sensitivity to capture the heterogeneity of observed effects, we…

The article introduces triangulation to converge evidence from corpus and experimental data, by means of two case studies in second language (L2) learners of Greek. The first case study investigates the acquisition of gender agreement, while the second probes the development of relative clauses. In both studies, findings from the corpus are tested…
