Despite the substantial expansion in vocabulary research since the 1980s, we still know very little about how vocabulary develops over time and what factors influence this development. This methodological overview discusses key issues and considerations in vocabulary breadth growth assessment to help advance research in this area. The report…

Developing advanced proficiency in a second language benefits both learners and the societies to which they belong. Educators, employers, and learners can define advanced level proficiency in a language as being able to use language for academic and professional purposes beyond daily life. But being able to use the language at work is not the only…

The same L2 speaking performance may be analysed and evaluated in very different ways by different teachers or raters. We present a new, technology-assisted research design which opens up to investigation the trajectories of convergence and divergence between raters. We tracked and recorded what different raters noticed when, whilst grading a…

In the field of educational psychology, self-regulation is part of a well-established research paradigm that has been extensively applied to learning contexts. However, despite proposals highlighting its benefits, some researchers claim that its cross-pollination into applied linguistics has been slow. In their recent "Applied…

School psychologists are increasingly tasked with assessing, supporting, and intervening with dual language learner (DLL) students, their teachers, and their families. Understanding the assets of bilingualism along with multiple issues associated with comprehensive practice with DLL has become paramount. Currently, practitioners often lack the…

On day one the author sets up the expectation that her kindergarten Spanish language immersion classroom will be a 100% target language environment. To accomplish this, the author implements several structures, routines, and expectations to maintain the immersion environment. Getting to know the students, modeling appropriate behavior, promoting…

Representations of a nation's history work as a powerful tool to consolidate a collective identity and build trust in the nation. School textbooks are ideological products that disseminate official ideas about a collective past and heritage; their depictions have an impact on shared understandings of a nation's history. However, what is included…

In this article we introduce Positive Psychology (PP), a relatively new subfield of psychology, and outline its development since the year 2000. We describe ways in which PP represents an exciting addition to the Second Language Acquisition (SLA) literature and the ways it is already influencing trends in education generally, thus creating…

Second language (L2) motivation research has been thriving for the past decades by emphasizing L2 motivation theories and describing the motivated learner, while relatively few studies have dealt with how to motivate students in a systematic way. Approaches in these studies either included investigations into the role of different motivational…

Early childhood researchers from across the U.S. came together to form the Early Learning Network (ELN) in 2016 with the mission to identify policies and practices that narrow opportunity gaps and help children maintain early learning success. Early Learning Network teams share what they have learned--and what it means for early childhood…

This coda article offers unified theoretical accounts of the major findings of the empirical studies in this special issue of "Optimizing Second Language Practice in the Classroom: Perspectives from Cognitive Psychology." We present a theoretical framework from cognitive psychology (desirable difficulty framework) and link it to the…

This commentary discusses some theoretical and methodological issues related to research on the spacing effect in second language acquisition research (SLA). There has been a growing interest in SLA in how the temporal distribution of input might impact language development. SLA research in this area has frequently drawn upon the rich field of…

The paper outlines current advancements in dynamic assessment (DA), an approach that has much intuitive appeal for many second language acquisition practitioners, yet that has to date failed to take root in language classrooms. DA distinguishes itself from other approaches to assessment by insisting that "mediated assistance" of the…

Research into the role of individual difference (ID) factors in the process of second and foreign language (L2) learning and teaching has been one of the most robust lines of inquiry in the field of second language acquisition (SLA; Dörnyei & Ryan, 2015; Griffiths & Soruç, 2020; Pawlak & Kruk, 2022). Most of these empirical…

This paper discusses the stage of second language acquisition known as attrition and what learners and teachers can do to prevent attrition and promote retention. Attrition is the stage at which a learner's attained proficiency declines due to a reduction of contact with the second language, whether from lack of contact with other speakers of the…
