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…

This study reveals hitherto overlooked effects of age of onset (AO) in immersive school contexts, using multiple measures over time so as to focus on fluctuations and trends in individual data. The second language (L2) English development was studied in 91 children who received 50-50 content and language integrated learning (CLIL) instruction in…

The Douglas Fir Group (2016) sought to articulate a transdisciplinary agenda for SLA but said little about multilingualism specifically. Moreover, many multilinguals are under siege in a worrisome world where threats to human difference have risen to the mainstream in the aftermath of Brexit and the 2016 U.S. presidential election. I argue that…

In volume 103 of "Modern Language Journal," Stephen May suggested that the "multilingual turn" has not fully delivered on its promises, pointing out second language acquisition (SLA) researchers' continued focus on parallel monolingualisms rather than on dynamic bi/multilingualism, the lack of theorization of historicity in…

Social aspects of second language acquisition (SLA) and the contexts in which people attempt to learn and use languages and seek to become integrated within new and changing cultures have been examined for decades from various theoretical perspectives. In this article, I present some of the ways in which 'social' experience is being theorized in…

A key insight of a transdisciplinary perspective on second language acquisition (SLA) as articulated by the Douglas Fir Group (2016) is its usage-based understanding of language. Evidence on the fundamental role that usage plays in shaping individual language knowledge is no doubt compelling. However, while the force of social interaction in…

Agency has attracted considerable attention, especially of late. Nevertheless, perceptions of language learners as nonagentive persist. In this article the Douglas Fir Group's call for a transdisciplinary perspective is heeded in a Complex Dynamic Systems Theory's (CDST) conceptualization of agency. It is suggested that CDST maintains the…

Cognition is not just 'in the head'; it extends well beyond the skull and the skin. Non-Cartesian Cognitive Science views cognition as being embodied, environmentally embedded, enacted, encultured, and socially distributed. The Douglas Fir Group (2016) likewise recognizes languages as emergent, social, integrated phenomena. Language is the…

What constitutes a "good teacher" and "good teaching" has come under much scrutiny in an age of globalization, transnationalism, and increased demands for accountability. It is against this evolving landscape and the pathbreaking work of the Douglas Fir Group (DFG, 2016) that this special issue engages the following two broad…

Language program evaluation is a pragmatic mode of inquiry that illuminates the complex nature of language-related interventions of various kinds, the factors that foster or constrain them, and the consequences that ensue. Program evaluation enables a variety of evidence-based decisions and actions, from designing programs and implementing…

This introductory paper highlights the promising potential of learner corpora to facilitate investigations of the developmental processes underlying L2 learning. It offers a critical discussion of the aspects in which the disciplines of learner corpus (LC) research and SLA would benefit from closer interdisciplinary engagement and introduces the…

This overview to "The Modern Language Journal"'s Focus Issue on Languages for Specific Purposes (LSP) takes a fresh look at issues examined in a 1991 article by Grosse and Voght. Reflecting on change drivers and growth in LSP, the authors comment on current challenges to the field and future research needs. Their remarks are based on new insights…

This introduction will provide a thematic overview of the major issues raised by Grosse and Voght (1991), "The Evolution of Languages for Specific Purposes in the United States," and the contributions in this Focus Issue that address those issues from a 2011 perspective. It will also explore contemporary (largely praxis-oriented) languages for…

Paper presented at the third meeting of the Central States Conference on the Teaching of Foreign Languages, April 15-17, 1971, in Detroit, Michigan. (DS)

Discusses a four-year project now in the second year at Earlham College to increase the use both by faculty and students of foreign languages. Provides the background to the project, the detailed objectives, and abbreviated comments on accomplishments to date. (EKN)
