This is a collaborative cross-sector research project involving a kōhanga reo (Māori immersion early childhood language nest) kura (Māori language immersion school) and university-based researchers. It focuses on tamariki (children) moving from kōhanga reo to kura classrooms and will examine the development of an 'akoranga whakawhiti', a transition programme that will be based at Te Kōhanga Reo o Ngā Kuaka in Hamilton. The over arching research question for this project is: Pēhea rā te āhuatanga me te kounga o ngā whakawhitinga mai i te kōhanga ki te kura mō ngā tamariki, whānau, kaiako me te hāpori? - What do effective transitions from kōhanga reo to kura look like, feel like, and sound like, for tamariki, whānau, kaiako and the community? The project aims to provide important new insights into learning and teaching in Māori-medium settings and into ways of enhancing transitions from Maori-medium early childhood education to Māori medium classrooms.
