In this chapter, I explore how the study of grammatical gender has been a prime example of the impact that boundary crossing can have on the understanding of a phenomenon by creating nuance through the incorporation and juxtaposition of multiple perspectives. In the first section, I start with a description of grammatical gender and its different…

Nowadays, research in second language acquisition (SLA) is becoming increasingly interdisciplinary while many technical frontiers and research hotspots have emerged. Many studies focus on interdisciplinary topics, but few in-depth studies have been conducted on interdisciplinarity. This study examined the interdisciplinarity of SLA and the…

This volume brings together original papers from language education scholars from around the world to explore, exemplify, and discuss the multiplicity of boundary crossing in language education.

English as a lingua franca (ELF) represents a substantial paradigm shift in ELT because it challenges the traditional norm of standard English. Despite this changing trend, there is a gap in research on incorporating ELF into in-service teachers' professional development (PD).

It is the interdisciplinary…

Recent research shows that musical training improves children's development of oral and aural skills. This study focuses on developing and testing a methodological framework (Music as a Medium of instruction, MMI) in English language teaching (ELT) by contrasting MMI and gamification methodologies with the participation of 22 Spanish children all…

Offering core academic credits (e.g., math, science) for completing agriculture, food, and natural resources (AFNR) coursework at the secondary school level has the potential to increase the strength of the AFNR program as well as student interdisciplinary learning. Informed by the Career and Technical Education Student Typology, we explored the…

The release of ChatGPT marked the beginning of a new era of AI-assisted plagiarism that disrupts traditional assessment practices in ESL composition. In the face of this challenge, educators are left with little guidance in controlling AI-assisted plagiarism, especially when conventional methods fail to detect AI-generated texts. One approach to…

The last two decades have seen a significant amount of interest in bilingual language learning and processing. A number of computational models have also been developed to account for bilingualism, with varying degrees of success. In this article, we first briefly introduce the significance of computational approaches to bilingual language…

The field of multilingual learner education has become increasingly complex, with longstanding efforts focused on promoting "access" to multilingual learners being criticized for failing to "transform" systems responsible for these students' marginalization. This essay brings clarity to the complex terrain of equity for…

English learner (EL) students face the challenge of learning a new language while simultaneously learning other subjects. Similarly, English as Second Language (ESL) teachers have the added responsibility of teaching academic language in STEM subjects to EL students, in addition to language teaching. This article explores how a participant…

There has been a significant growth in the field of Chinese language education, which has necessitated to examine the current state of key research contributions of the Chinese language in teaching methodologies, learning processes, and textbook development.
