A bibliometric review of research on English as a medium of instruction (EMI), 1974-2022

This bibliometric review employs science mapping to trace the development of the EMI-related literature and obtained 1378 relevant Scopus-indexed documents published between 1974 and 2022. The study uses co-author analysis, coupling analysis and co-occurrence analysis to reveal the co-authorship network, the most prolific authors, and the most commonly researched EMI topics. The result reveals a rapidly growing publication trajectory since the 2000s when global internationalisation became prominent. However, the overall outgrowth reaches a modest comfort. While this literature is worldwide in scope, publications in four countries - the United Kingdom, Hong Kong, Spain, and the United States - provided the most significant publications. Authors with the most publications and citations also come from these countries.
