This work provides a chronological and thematic account of empirical studies and position papers on second language (L2) writing scholarship from a complex dynamic systems theory (CDST) perspective. As a theoretical framework, CDST was formally introduced into applied linguistics research by Diane Larsen-Freeman in 1994 (Larsen-Freeman, 1994).…

This article addresses different ways scholars conceptualize the multilingual repertoire. Formal and functional approaches investigate crosslinguistic influence across clearly demarcated languages, while dynamic systems theory and translanguaging approaches question countability and boundedness of languages. Problems with both perspectives are…

In language teaching, current understanding of complex classroom contexts and post-methods L2 pedagogy encourages us to adopt a situated and dynamic perspective of the language classroom. Exemplary teaching in such contexts is characterized by critical moment to moment decision-making for building L2 classroom environments that are engaging,…

Complexity Theory (CT) provides a useful framework for understanding Second Language Acquisition (SLA). Using an ecological model, CT studies the dynamic processes of change and emergent outcomes over time, tracing back how trajectories may have been affected by changes in and interactions among multiple variables and subsystems. Language learners…

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…

The launching of The Journal for the Psychology of Language Learning is a signal achievement. I begin this commentary by speculating on why it is that the Psychology of Language Learning (PLL) has enjoyed such vigor of late. I expect that one reason is the coming together of a critical mass of researchers and strong leaders over their shared…

Language classrooms are complex systems, but theory often simplifies these processes making researching effectiveness difficult. Assemblage theory -- a theory of complexity in the social sciences -- allows us to examine complexity in the language classroom. In this paper, I present an account of the language classroom that captures the complexity,…

Children are members of families and communities, and the languages learnt within these contexts contribute to a child's sense of "belonging, being and becoming" throughout life (Department of Education Employment and Workplace Relations, 2009). Encouraging children to bring their home languages into early childhood education and care…

Drawing on theoretical insights from a complex dynamic systems framework, this work explores the ways that learner selves, as they relate to learning and using languages, manifest across different contexts and timescales and emerge in interaction with various factors. First, a broad overview of dynamically-oriented L2 motivation research is…

Since its inception in the late 1960's, the field of Second Language Acquisition (SLA) has undergone many transformations. As pre-existing theories have been expanded upon and new theories introduced, researchers and practitioners have come to a deeper understanding of the second language (L2) learning process. The past two decades, in particular,…

For novice and expert English language teaching professionals alike, it is important to understand the dynamic complexity of the context in which we work to intentionally and strategically forge a relevant and personally meaningful, continuing professional development path. English language teaching has long outgrown a…

James P. Lantolf is George and Jane Greer Professor Emeritus of Language Acquisition and Applied Linguistics and former director of the Center for Advanced Language Proficiency Education and Research at the Pennsylvania State University, USA. He is currently Adjunct Professor of Applied Linguistics in the same academic unit at Xi'an Jiaotong…

Bringing a complex systems perspective to bear on classroom-oriented research challenges researchers to think differently, seeing the classroom ecology as one dynamic system nested in a hierarchy of such systems at different levels of scale, all of which are spatially and temporally situated. This article begins with an introduction to complex…

We identify contributions in this special issue in terms of two essential ways of threading systemic change for language equity in schools: theories/concepts from school governance down to classroom practice, and values/morals from practical realities in classrooms up. We characterize 'language equity' as a sense of belonging and meaningful…

While approaching second language acquisition from a complex dynamic systems perspective makes a lot of intuitive sense, it is difficult for a number of reasons to operationalise such a dynamic approach in research terms. For example, the most common research paradigms in the social sciences tend to examine variables in relative isolation rather…
