Kari Moana and Sara, university-based teacher educators and researchers in UC’s Te Kaupeka Ako Faculty of Education, explore the intense debate surrounding mātauranga Māori in Aotearoa New Zealand's science classrooms. As curricular reforms challenge traditional views, critics argue that integrating Indigenous knowledge could dilute "real" science, while supporters say it's long overdue. This discussion delves into whether we're on the verge of an innovative fusion of knowledge systems or entering a new realm of controversy. With expertise in mātauranga Māori, science education, and decolonisation, Kari Moana and Sara examine the transformative possibilities at the intersection of Indigenous knowledge and science in Aotearoa and the Pacific.
