This research investigates how international educational collaboration (IEC) as a social activity adapts to global crises: COVID-19 and the Russian's invasion in Ukraine. We focus on Finnish higher education institutions (HEIs) and non-governmental organisations (NGOs) that actively provide IEC activities, such as student exchange, education export and educational capacity building abroad. Drawing from the sociology of conventions (SC) and the concept of social practices, we formulate a multidimensional framework that connects regimes of justification, and social practices that emerge in crises. Considering crises as a critical test, we analyse how IEC cope with unexpected situations that require establishing new justifications of public accountability and morality, and practices that fit the crises situation. Our empirical data collected through a two-stage open-ended questionnaire in 2021 and 2022 enables us to consider the recent trends and potential future(s) of IEC. Empirically, we conclude that coping with global crises requires IEC actors to make changes in IEC practices. Analytically, we theorise that regimes of justification and social practices that emerge during crises (crisis practices) are interconnected. Thus, this study contributes to practice-oriented frame by considering accountability of practices in the unexpected circumstances, enhancing the understanding of how different organisations adapt to turbulent times.
