One of the greatest challenges facing democracies is how to live together with difference. The growth of globalisation and international migration has presented schools with increased opportunities and challenges related to learning from and living with superdiversity. Yet within current policy settings and educational practices, the alignment between superdiversity and democratic education is not explicitly foregrounded. In this paper I examine how teachers (n = 24) from four superdiverse secondary schools in Aotearoa New Zealand's responded to growing cultural, linguistic and religious diversity in their classrooms. By examining empirical evidence from teacher's practices, the paper illustrates how Dewey's philosophy of learning by living together with difference, placing a priority on shared interests and developing a socio-political awareness of inequalities provides valuable insights for democratic education. The study illustrates the importance of recognising the complexity of interactions in superdiverse contexts and the significant role that teachers can play in creating conditions for inclusive classrooms where democracy can be lived and learned. It also highlights how teachers themselves, can undergo a journey toward developing more inclusive and justice-oriented pedagogical practices that support both Indigenous and ethnic minority groups in their schools.
