Abstract
<jats:p>The past decade has witnessed a revolution in the learning landscape worldwide, driven by the rapid expansion of digital technologies and open-access learning platforms. Among them, Massive Open Online Courses (MOOCs) have been at the centre stage of learning innovation, promising flexible, low-cost, and borderless learning. This study aims to map the global research landscape of Massive Open Online Courses (MOOCs) using bibliometric techniques to understand the evolution, intellectual structure, and thematic trends of the field. Drawing from a dataset of 10,059 publications indexed in Scopus, the analysis was conducted using Bibliometrix (R package) and VOSviewer to perform co-citation analysis, bibliographic coupling, and thematic mapping. The results reveal that the United States, China, and the United Kingdom are the leading contributors in terms of research output. Key institutions such as MIT and Stanford dominate citation impact, while authors like Yuan L. and Alario-Hoyos S. show high scholarly influence. The analysis reveals a mismatch between research output volume and scholarly influence, particularly in certain regions. Thematic mapping highlights core clusters in pedagogy, learner engagement, and assessment tools, while underexplored areas include inclusivity, multilingual access, and international policy coordination. A key contribution of this study lies in uncovering structures in the MOOC literature which reveal hidden intersections between technical, pedagogical, and policy-related domains. The findings underscore the growing maturity of MOOCs as an interdisciplinary field, while also pointing to fragmentation in research efforts. This study not only charts the growth and diversification of MOOC research but also highlights neglected areas crucial for educational equity and global collaboration. The findings have applied value for educators, platform developers, and policymakers seeking to expand the reach, quality, and impacts of MOOCs in an evolving digital learning environment.</jats:p>
