Mobile applications for language learning

Abstract Modern mobile applications (apps) have profoundly influenced not only social communication and information dissemination but also language learning. These applications, such as Babbel, Busuu, and Duolingo, are increasingly accepted by language learners and have gained attention from researchers exploring their educational contributions. This chapter provides an overview of research on mobile applications as crucial sites for language acquisition, summarizing current research issues and insights of the research methods. It offers practical advice for researchers entering this field, including reviews of exemplary studies that highlight essential methodologies and findings. Additionally, the chapter addresses ethical considerations and research integrity in studying mobile applications. It concludes by examining challenges in research methodologies and suggests future directions, enriching the broader dialogue on how mobile applications can advance language education.
