This book offers a comprehensive report on a three-year, cross-cultural, critical participatory action research study, conducted in children homes and communities in Fiji. This project contributed to building sustainable local capacity in communities without access to early childhood services, so as to promote preschool children literacy development in their home languages and English. The book includes rich descriptions of the young children lived, multilingual literacy practices in their home and community contexts. This work advances research-based practices for fostering young children multilingual literacy and building community capacity in a post-colonial Pasifika context; further, it shares valuable insights into processes and complexities that are inherent to multiliteracy and cross-cultural research.
