In this article we address two key questions in the application of dynamical systems theory (DST) to second language acquisition (SLA) that have not been resolved in recent debates about this issue. The first question relates to reductionism. Is an antireductionist position a necessary element of DST? We show that the radical antireductionist…

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…

This article revisits complex dynamic systems theory (CDST) and provides a new synthesis that, the authors argue, may empower language teachers. The particular focus is on the interplay between change and stability in complex dynamic systems, including language teaching and learning. The article identifies four key dynamical properties of complex…

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…

Research into second language acquisition (SLA) has shown that individual difference (ID) variables can be strong predictors of language achievement (e.g., Dornyei, 2003; Skehan, 2003). Traditionally, this research conceptualized ID variables as static and monolithic variables (e.g., Dornyei, 2010). More recently scholars have questioned this…

Complex Dynamic Systems Theory (CDST) has significantly reshaped our understanding of second language learning and teaching across the micro, meso, and macro levels for several decades since its systematic introduction by Larsen-Freeman and Cameron (2008). This study conducts a comprehensive review of empirical research on second language learning…

The number of immigrant students in Finland is increasing; thus, this qualitative case study investigates ways of providing targeted support measures for recently arrived Finnish language learners (RAFLLs) in Finnish lower secondary education. Focusing on linguistic responsiveness, the teaching arrangements and support measures are examined not…

Background/purpose: Although studies on teacher research are becoming more common in English language teaching (ELT), there is still a lack of understanding regarding how university lecturers shape their research identities. Using Ecological systems theory and Self-determination theory, this study examines the construction of research identities…

In the field of applied linguistics, Diane Larsen-Freeman is widely recognized, among her numerous contributions, as the originator of Complex Dynamic Systems Theory (CDST). Over the years since her seminal publication (Larsen-Freeman, 1997), CDST has evolved into a meta-theory that guides the field's thinking on a variety of developmental…

This study compares two leadership styles, emergent leader (EL) and assigned leader (AL), to explore effective leadership in second language (L2) group work. ELs were spontaneously chosen by the group, while ALs were pre-assigned by teachers before the task. The study involved 45 university students, who were divided into seven EL groups (n = 21)…

As a social-interactional positive behavior, the flow of compassion (i.e., selfcompassion, compassion for others, and compassion from others), which refers to sensitivity to suffering in self and others with a commitment to try to alleviate and prevent it, has yet to be investigated in a highly social-interactional context such as foreign language…

While many previous studies focused on English-as-a-Foreign-Language (EFL) teachers' teaching practices in urban schools, little study has been indulged regarding pre-service English teachers' (PSTs) challenges and experiences to practice teaching in a rural school. This study aimed to explore various difficulties encountered by urban PSTs during…

Purpose: The purpose of this study is to examine the formation of sustainable development competencies (SDCs) in future primary school teachers during English for specific purposes classes, and to assess the correlation between English proficiency and the development of SDCs, including Collaboration, Strategic thinking, Critical thinking,…

This paper explores the experiences of practicing bilingual (English/Spanish, English/Portuguese, and English/Haitian Creole) and English as a Second Language teachers after completing a Bilingual Bicultural Education Certification program. It highlights how teachers defined success when working with their emergent bilingual students and names the…

The English language is a catalyst for economic growth, modernization, and globalization. In this milieu, English language competency--defined as the practical ability to use English effectively in diverse contexts, encompassing linguistic, cognitive, and intercultural skills--is recognized as an essential skill (Amor et al., 2023). Research on…
