Goals are central to understanding how students learn a second language. Much of the existing research on goals in the field of language learning has focused exclusively on achievement goals, particularly mastery and performance goals. However, exclusively focusing on achievement goals precludes language researchers from exploring other important…

The key to successful language learning depends on the extent to which learners are self-regulated in learning a second or foreign language (L2). In this process, learners' perceptions and beliefs about their abilities play a crucial role in predicting or controlling positive or negative emotions, motivation and the use of strategies. Therefore,…

Peter MacIntyre's 35-years of research in SLA, psychology of language learning, and communication was systematically reviewed in six sections driven by subjective guidelines developed for the purposes of the present survey. To operationalize the objectives of the sections, an impressionistic methodology was created for analysis, according to which…

Adopting Complex Dynamic Systems Theory (CDST) in Second Language Acquisition (SLA) is a testament to the revolutionary and evolutionary advancement in theory and empirical practice in the field. CDST is revolutionary for the fact that it warrants systems thinking of SLA phenomena that breaks the chain of dichotomous conceptualization on vital…

Identifying changing patterns of stability and variability is crucial when examining second language development (SLD) from a complex dynamic systems theory (CDST) perspective (Larsen-Freeman, 2020). By studying attractor states, or recurrent patterns of stability, light can be shed on the underlying dynamics of a complex dynamic system (van Geert…

In this article, we highlight the important achievements of the editors and contributors in this special issue. We argue that this collection of studies on individual differences (IDs) advances the field in terms of theoretical diversification, methodological improvement, and pedagogical innovation. We also contend that a renewed interest in ID…

Second language development can be viewed as a complex and dynamic process in which learners follow non-linear trajectories and develop their language over a period of time (Larsen-Freeman, 2006). Intrinsic to the view of Complex Dynamic Systems Theory (CDST), a system is composed of hierarchical, interdependent subcomponents (learner, learner…

From a complex dynamic systems (CDST) perspective, language is understood as a dynamic system comprised of subsystems that change and develop over time in response to learner-internal and -external factors (Verspoor et al., 2008). Accordingly, language development is seen as a process responsive to the dynamic interaction between the learner and…

Since its inception in 2005, YouTube has grown to become one of the most trafficked online platforms in the world. Accordingly, second language (L2) research interest on the topic has also increased, with studies investigating its use in formal and informal settings. Given this, the goal of this conceptual paper is to identify patterns within L2…

At the turn of the new millennium, in an article published in "Language Teaching Research" in 2000, Dörnyei and Kormos proposed that 'active learner engagement is a key concern' for all instructed language learning. Since then, language engagement research has increased exponentially. In this article, we present a systematic review of 20…

This systematic review synthesizes recent trends in English for Specific Purposes (ESP) research, examining 149 empirical studies published in Social Sciences Citation Index (SSCI) journals between 2014 and 2023. Employing a six-dimensional coding framework, we investigated participants, pedagogical methods, research methods, research foci,…

While language aptitude and motivation are considered to be important contributors to second language (L2) attainment, two major gaps in the past research have been (1) a lack of nonlinear models stemming from a naive and tacit assumption that learning outcomes are linearly related to their predictors, and (2) a lack of unified and integrative…

Given the importance of collocational knowledge for second language learning, how collocation learning can be facilitated is an important question. The present study examined the effects of three different practice schedules on collocation learning: node massed, collocation massed, and collocation spaced. In the node-massed schedule, three…

In Krashen's theory of second-language acquisition he claims that there is distinction between language acquisition and language learning, a distinction which other second-language acquisition researchers have called "perhaps the most important conceptualization" in the field and which has made possible the most productive models of SLA.…

Construction Grammar has been a prominent framework in linguistic research for nearly three decades, attracting scholars from various disciplines, including language acquisition, corpus linguistics, and psycholinguistics. While considerable progress has been made in understanding the first language (L1) construction learning of various languages,…
