This paper presents a bibliometric analysis of educational research in the Social Science Citation Index (SSCI) from 2008 to 2017. Using GraphPad Prism and VOSviewer tools, we analyzed 3,484 articles from South Korea, Singapore, and Japan.

South Korea had the most number of articles in the top 10 most popular journals, which could owing to many South Korea scholars concern nation and regional journals have relative higher acceptance rate. Japan and South Korea had the most common studies concerning educational research. The annual number of articles showed strong positive correlations with research and development (R&D) expenditures and R&D expenditures as a percentage of GDP in South Korea.
