The rise of Massive Open Online Courses (MOOCs) has democratised education, yet student dropout remains a persistent challenge. This research tackles this issue by analysing 1,273 publications on MOOC dropout rates (2020-2023) from the Scopus database using VOSviewer, a bibliometric analysis tool. By mapping the intellectual landscape, the study identifies key research questions (e.g., concerning MOOC dropout, learning motivation) and emerging themes (e.g., classification performance, engagement). This comprehensive analysis provides a roadmap for future research, pinpointing areas for further investigation and knowledge advancement.
