Bibliometric analysis on global citizenship education in higher education

This study examines the landscape of Global Citizenship Education (GCE) studies in higher education through four key questions: (1) how GCE literature is distributed based on annual growth and geographical regions; (2) which publications, authors, and collaborations have the most influence; (3) what research themes are frequently studied; and (4) what specific topics dominate the field. These questions respond to the increasing importance of GCE in shaping teaching and learning in higher education. A quantitative bibliometric approach was used to analyze literature from the Scopus database, using keywords such as 'global citizenship', 'education', 'teach', 'learn', 'higher education', 'university', and 'college'. Boolean operators and truncation were applied to refine search results. Inclusion criteria included articles published from 2004 to 2023, peer-reviewed, categorised under social sciences, and written in English. Parameters analyzed include productivity, impact, collaboration, and content using VOSviewer and Biblioshiny. The findings reveal a growing interest in GCE research, although citation rates have declined. Most influential works originate from the USA and UK, with significant global collaboration. Clustering analysis highlights current research directions and suggests potential theoretical frameworks. The study provides insight into the evolution of GCE in higher education and outlines areas for future research.
