Purpose: The purpose of this study is to examine similar and/or different perspectives on, and practices of online-learning interaction as projected by the participating educators who are from either Korea or the USA. Design/methodology/approach: In this study, the authors analyzed how college instructors from two countries, Korea and the USA, consider the role of online-learning interaction in their students' learning by interviewing nine instructors from both countries. The authors examined the educators' responses using constructivism and Confucianism as the frame of reference. Findings: The analysis showed that the US instructors tend to focus on learner-to-learner interaction, whereas Korean instructors emphasized teacher-to-learner interaction. Korean instructors perceived a gap between ideal and reality in integrating interaction as a part of online activities in the course. Originality/value: This study focuses on a cross-national comparison of online-learning interaction between Korea and the USA. Thus, it will provide practical ideas for global or multicultural user experiences on online-learning courses.
