Through signs and symbols, language serves as a means of expressing ideas and sentiments. These signs and symbols are used to encode and decode the information. The world has many different languages in use. As their first language, a baby learns their mother tongue. From birth, he or she is exposed to this language. Any additional language that…

Metacognitive awareness is essential in regulating second language (L2) listening and has been predominantly assessed by a multidimensional instrument named the Metacognitive Awareness Listening Questionnaire (MALQ). Since previous studies have yielded inconclusive evidence concerning the generalization of MALQ, it is important to examine the…

How can syntactic and learnability analyses inform each other, and thus deepen our understanding of syntax and its acquisition? This dissertation illuminates this question through three case studies in Korean syntax. I examine cases in which two structures that display distinct syntactic properties share extremely similar surface forms, thus…

Research has demonstrated that features of lexical and lexicogrammatical use are important predictors of productive second language (L2) proficiency (e.g. Kyle et al. 2018). While some features of lexical use have been studied with L2s other than English (e.g. Tracy-Ventura 2017), multivariate lexical and lexicogrammatical approaches in these L2s…

This study aims to investigate and compare the efficiencies of gamification and ludicization in foreign language learning regarding learning outcome, readiness, engagement, and academic buoyancy. Regarding the theoretical frameworks, gamification and ludicization, feasible in foreign language learning through interaction and problem-solving…

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…

The study aimed to explore the evidence of first language (L1) mediation in second language (L2) word associations and the L2 learner-related factors affecting the extent of L1 mediation with the following approaches. First, different from previous research, word association tests (WATs) embraced both receptive and productive word associations in…

This article presents a theoretical review of and methodological guidelines for the study of two key notions in second language acquisition research, complexity and difficulty. The term "complexity" has gained considerable currency over the past decades and has taken on a wide range of meanings. We argue for a more restricted…

As China joined the World Trade Organization (WTO) and its national strength continued to grow, enthusiasm for learning Chinese has been heating up globally. Chinese language education has gradually integrated into the education systems of more countries, becoming a significant focus of attention and study. However, despite the increasing demand…

This book constitutes a holistic study of sociolinguistic development among adult second language (L2) learners in a naturalistic setting. Combining results from a cross-sectional and longitudinal micro-development study, it examines the acquisition of both the productive and interpretive skills necessary to engage with the contextually sensitive…

Previous research has demonstrated that formulaic sequences (FSs), including such types as collocations, idioms, or phrasal verbs, are ubiquitous and play an important role in second/foreign language (L2) proficiency. However, FSs can pose significant challenges for L2 learners, especially those in contexts where there is limited exposure to L2…

The fluency task, which involves lexical retrieval from a categorical or thematic prompt, has been a crucial paradigm in studies about lexicon in bilingualism and additional languages. Particularly, there has been a very productive cognitive turn towards analytical models based on the exploration of the cognitive processes underlying the mental…

The development of research methodology in any scientific field is closely tied to technological advancements that allow for deeper and more sophisticated data analysis. To help readers understanding the scope of current lexical availability research, this chapter provides a description of the tools and research resources specifically developed…

This article examines how tertiary language learners of German engaged with the novel "Blutbuch" (2022) by Swiss author Kim de l'Horizon. Celebrated as the first nonbinary novel in German literature, excerpts of this autofictional text were taught in a 3-week unit, which was part of a semester-long German course targeted at university…

In the United States, numerous world language programs face criticism by being labeled as useless and inferior, resulting in curriculum and funding cuts. Despite defending their practicality, showing how vital skills are acquired through participation in these courses, many programs' efforts often fall short in conveying the essential role of…
