Developing Listening Comprehension Using Podcasts in Second Language Education: A Systematic Overview of Recent Pedagogical Innovations (2019–2025)

This study illustrates a bibliometric analysis of scholarly literature on podcasting in second language (L2) listening skill development from 2019 to 2025, using the Scopus database. The research aims to identify publication trends, top authors, notable journals, frequently used keywords, and patterns of scholarly collaboration related to podcast-assisted listening instruction. A total of 1033 documents were retrieved from Scopus, of which 74 were reanalysed in depth related to Linguistics. The data was analysed using Excel for initial categorisation and VOSviewer software for visualising keyword co-occurrence and co-authorship networks. Keyword analysis revealed a strong connection between podcasting, metacognitive strategies, digital learning environments, and authentic input in Second Language (L2) contexts. Co-authorship maps revealed growing international collaboration among researchers and institutions worldwide. The analysis offers a macro-level overview of how podcasts are integrated into L2 listening instruction, identifying gaps for future research. The study also recommends future exploration of AI-enhanced podcast platforms, personalized listening instruction, and inclusive designs that accommodate learners with diverse needs. These findings contribute to a better understanding of current practices in digital listening pedagogy and offer direction for future innovations in language education.
