Despite growing interest in immersive block models in higher education, very little is known about the experiences of international students in these non-traditional forms of learning. To enable an initial view of how international students perceive and perform in an immersive block model, we used an exploratory mixed methods approach to examine the academic success, satisfaction, and experiences of international students in a 6-week immersive block model at a regional public Australian university. Inferential statistical tests were used to explore the success rates and unit and teaching satisfaction of onshore and offshore international students in the immersive block model and in the traditional trimester model. Overall, the immersive block model made a significant positive difference to the academic success of international students, both onshore and offshore. However, a decline in satisfaction was observed among science and engineering students, contrasting with an increase in satisfaction among business and arts students. Data collected through semi-guided interviews with 10 students from this latter group indicate several key benefits and challenges associated with immersive block learning. Students reported heightened focus and motivation, supportive teaching, and a healthy study-work-life balance. Challenges included not knowing what to expect, forming social connections with classmates, and the fast turnover between assessments. These findings indicate that it is important for institutions to prepare international students well for the pace and time management demands of studying in an immersive block model and to encourage the formation of social connections. Assessment timing, volume, and scaffolding should also be key considerations in immersive block model curriculum design.
