This three-phase project that will support the Frank Hilton Organization (FHO) to provide evidence-based training to Fijian caregivers on how to maximise communication rich environments. The first two research focused phases aim to: (Phase 1) map young Fijian children’s communication (oral language and literacy) across environments to consequently: (a) identify Fijian family language policies/rules, and (b) identify family communication behaviours that support or hinder home-language maintenance and multilingual language/literacy acquisition, and (Phase 2) uses the outcomes of Phase 1 to develop and evaluate an evidence-based communication program/playgroup, that can be implemented by Fijian-speaking caregivers (professionals/parents) to create communication rich learning environments where young Fijian children are encouraged to maintain their home language and culture during oral language and literacy activities. This program will be a scalable prototype that can be extended to support children of all linguistic backgrounds. Phase 3 provides playgroup participants ongoing support to maintain learnings.
