Contextualized Mathematics Instruction in an Indigenous Secondary School Setting: Evidence from a Kalanguya Community in Northern Philippines

Abstract

Contextualization has been widely recognized as an effective pedagogical approach in enhancing learner engagement and conceptual understanding, particularly in culturally diverse and indigenous learning contexts. In the Philippines, indigenous learners often experience a disconnect between school mathematics and their lived realities, contributing to persistent achievement gaps. This study examined the implementation and impact of contextualized Mathematics instruction in an indigenous secondary school serving a Kalanguya community in Northern Philippines. Anchored in culturally responsive pedagogy and constructivist learning theory, the study employed a qualitative case study design involving classroom observations, semi-structured interviews with teachers and students, and analysis of instructional materials. Findings revealed that contextualized Mathematics instruction through the use of indigenous practices, community-based problem situations, and local linguistic references enhanced learners’ conceptual understanding, participation, and confidence in Mathematics. The study further found that culturally grounded instruction fostered learner identity affirmation and strengthened teacher–student relationships. The paper argues that contextualized Mathematics instruction is not merely a pedagogical strategy but a culturally sustaining practice that supports equity and inclusion in indigenous education. Implications for teaching practice, curriculum design, and educational policy are discussed.
