The Mother Tongue-Based Bi/Multilingual Education (MTB MLE) project has been conducted by the Resource Center for Documentation and Revitalization of Endangered Languages and Cultures, Research Institute for Languages and Cultures of Asia, Mahidol University. This project has been supported by UNICEF (Thailand), Thailand Research Fund and Mahidol University. The project focuses on building a strong foundation for native language and culture to overcome linguistic barriers and cultural differences that hinder learning progress. The program starts from kindergarten level to Grade 6. The MTB MLE students are literate in Patani Malay language based on Thai scripts, while Thai language is firstly taught orally using Total Physical Response (TPR) approach, then Thai literacy is introduced by Thai Transfer Primer. Patani Malay is used as a medium of instruction to ensure higher academic performance and a bridge to learning through Thai language. Learning of Standard Malay language using Jawi (Arabic script) and Rumi (Roman script) is introduced at higher grades to facilitate Malay studies as part of equipping students to become ready for becoming ASEAN citizens.
