DEVELOPMENT AND VALIDATION OF A TANDAGANON LANGUAGE-BASED STRATEGIC INTERVENTION MATERIAL FOR GRADE 1 LEARNERS IN MOTHER TONGUE-BASED MULTILINGUAL EDUCATION

Education

This study examines the development and validation of a Strategic Intervention Material (SIM) for Grade 1 learners, using the Tandaganon language to address the least learned competencies in the context of Mother Tongue-Based Multilingual Education (MTB-MLE). Since the implementation of MTB-MLE in the Philippines, the Department of Education (DepEd) has focused on using the learners' first languages to support their literacy and language development. This study addresses a gap by creating a SIM that incorporates the local language, enhancing students' proficiency in reading, writing, and oral communication. Using a descriptive-developmental research design, the study involved experts and teachers in validating the content and functionality of the SIM through both qualitative and quantitative data. The results showed that the SIM was highly regarded by both groups, receiving excellent ratings for its content organization, clarity, and alignment with the Most Essential Learning Competencies (MELCs). The SIM was praised for its structured approach, which facilitates a better understanding of learning objectives and engages learners with culturally relevant materials. Designed to target the least learned competencies, the SIM supports the development of foundational literacy skills while honoring the cultural context of Tandaganon-speaking students. The study emphasizes the importance of developing localized, language-specific instructional materials to support multilingual education, promoting more inclusive and effective learning environments that contribute to improved learning outcomes for students in diverse linguistic settings.
