This document discusses mother tongue-based multilingual education for Timor-Leste. It begins with an outline of the presentation topics, including definitions of mother tongue and this educational approach. The objective is to promote cultural identity, enhance literacy, and improve educational access and success. Research shows high repetition and dropout rates when the language of instruction is not the learner's mother tongue. The theoretical framework is based on place-based pedagogy and building on what learners already know. Challenges include issues of national unity, lack of writing systems for local languages, and lack of teaching resources. Questions are raised about using mother tongue versus a national language in early education.
