The study reported here used a practice theory lens to understand vocational education and training (VET) teachers' current practices in supporting integration of learning in educational institutions and workplaces -- specifically for refugee and migrant students. A case study was conducted with 10 teachers delivering aged care programmes in South East Queensland, Australia and in a municipality in West Sweden. During in-depth interviews teachers explained the enabling and challenging aspects of their practice, and specific strategies they used to support students with integration of learning in the two main sites. Analyses of data concentrated on understanding three types of arrangements in the practice architectures at the two learning sites. Teachers extended their everyday pedagogical approaches to support integration of learning and meet the specific needs of refugee and migrant students. Their teaching comprised interdependent practices of VET and aged care in two settings, each with distinct ecologies of practice. Their narratives reflect contestations between practice traditions of aged care practices in Australia and Sweden, and students' understandings and reflections of practices in their birth countries. We conclude that teacher training and adjustments to these arrangements can bridge contestations between the enacted and experienced curriculum in the two sites.
