Lexical proficiency in a second language (L2) has long been effectively assessed through the measurement of various lexical indices, or textual characteristics that act as observable indicators of such conceptual categories as lexical richness, diversity, sophistication, and fluency. While many studies have established links between these lexical…

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…

In this study, I analyze how 15 world language (WL) preservice and in-service teachers in the United States negotiated the concept of translanguaging in an online, asynchronous educational linguistics class. Integrating language orientations, an ecological model of language teacher agency, a critical reflection framework, and a critical…

In the Yoruba community, proverbs are regarded as Yoruba philosophy repository, with wisdom, brevity, criticality, and stored experience that are believed to be a viable tool of acquiring the language. Hinging on reversing language shift model theory, the study investigated: (a) whether Yoruba proverbs are effective in the acquisition of Yoruba…

Domestic immersion (DI) is an effective context for postsecondary language learning, given that DI's instructor-curated environments promote meaningful second language use while providing abundant support for learners. However, DI is at present understudied within second language acquisition research, especially when compared to its more…

Many scholars have identified teacher education (TE) as a crucial site for strengthening the research-practice interface. Much of this work has focused on formal TE opportunities, English-language instructors, or university-level contexts. Less is known about how other educator demographics engage with second language (L2) research throughout…

Developing proficiency and intercultural competence are goals promoted by the Modern Language Association and widely shared by postsecondary second language programs across the United States. Although the development of proficiency has been studied extensively in this context, comparatively little is known about how intercultural competence…

In Canada, growing awareness of multilingualism in language teacher education requires educators to rethink how we practice language education. Many are increasingly questioning how established English-French official language programming can be reconciled with the reviving and reclaiming of Indigenous languages, and how we might think across…

This theoretical article, with recommendations for practice, interrogates how the field discusses dual language bilingual education (DLBE) models in the United States, with international implications for bilingual, immersion, and content and language integrated learning contexts. We reconceptualize the equity problems and potentials of so-called…

Languages shape worldviews, inform teacher values and behaviors, and are not disconnected from local political, sociocultural, and ecological contexts. For Indigenous peoples, language, land, and culture are inseparable. In contrast, English carries a human-centered, colonial, imperialist, and assimilationist legacy that persists in language…

Critical place-based pedagogies are closely tied to the social space of teachers and learners, aiming to raise awareness and support efforts for positive change. Social space shapes--and is shaped by--language teaching and learning. A critical approach to language teacher education must always engage with space and place, and contextual awareness…

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…

This study examines critical language-related events (CLREs) experienced by 28 teacher candidates (TCs) from various content areas at a US Hispanic-serving institution, employing a critical reflection framework. Through narrative inquiry, it examines how these events shape TCs' worldviews and behaviors about language use, language learning, and…

The adjustment of syntactic and phraseological complexity is a key consideration in text adaptation. However, research on this topic in the context of Chinese as a second language (CSL) remains limited. Using 700 CSL reading texts graded following the newly issued Chinese Proficiency Grading Standards for International Chinese Language Education,…

The recent dynamic turn in second language acquisition research has called for an investigation in learner agency by taking its complex dynamic nature into account. Informed by complex dynamic systems theory (CDST), this study investigated the agency of learners in a complex educational context where mainstream schooling and private tutoring…
