The purpose of this qualitative study was to explore the classroom discussion engagement experiences, the challenges faced and strategies for their solution, of eight international Indonesian masters students in one public university in the United Kingdom through a demographic questionnaire and semi-structured interviews. The results indicated that the participants faced some speaking challenges in engaging in discussion, including (1) language barriers, (2) individual matters, and (3) academic culture differences. To cope with those challenges, the participants have undertaken strategies, such as (1) having the verbal response, (2) utilising learning sources, and (3) maintaining a positive motivation.
