ABSTRACT
The study determined the challenges faced by mountain high school teachers in the integration of indigenous materials in teaching mathematics as a basis for program recommendation in the Municipality of Leon during the School Year 2025–2026. Employing qualitative research method, the study utilized ten (10 mathematics teachers who shared their narratives through in-depth interviews. The collected narratives were then consolidated, transcribed, analyzed, and interpreted using a thematic approach. Based on the responses from the in-depth interviews with mathematics teachers from various mountain high schools in the Municipality of Leon, those who integrate indigenous materials face diverse challenges, including teacher preparation and lack of training, limited resources and instructional materials, and language and conceptual barriers. To address these challenges in integrating indigenous materials in mathematics instruction, teachers employed professional development and teacher training, development of culturally relevant instructional materials, and culturally responsive teaching strategies.

INTRODUCTION
Mathematics instruction in many formal school systems has long been dominated by abstract, decontextualized approaches that can feel disconnected from the daily lives and cultural practices of learners — a disparity that is particularly evident in Indigenous and mountain communities.
Researchers argue that this cultural dissonance between “school mathematics” and community mathematical practices contributes to low engagement and poor conceptual understanding among students from indigenous backgrounds. Integrating local and indigenous materials into mathematics teaching is therefore proposed as a form of culturally responsive pedagogy and ethnomathematics that can make concepts meaningful, increase relevance, and help students transfer school learning to real-life contexts (Battibwe, 2024).
Mountain high schools — often located in geographically remote and culturally distinct communities — face additional constraints that affect teaching and learning: limited access to instructional resources, teacher isolation, and curricular materials that are not tailored to local ways of knowing. In these contexts, teachers’ practices in sourcing, adapting, and integrating indigenous materials (for example, local tools, traditional games, crafts, measurement practices, and counting systems) become central to students’ access to meaningful mathematics learning. Studies from diverse regions show that when teachers intentionally use indigenous cultural elements and locally available materials, student engagement and learning outcomes in mathematics tend to improve (Hatton, 2024).
Teacher beliefs, preparation, and available supports strongly shape whether and how indigenous materials are integrated. Research indicates that teachers who recognize the epistemic value of indigenous knowledge, who receive targeted professional development, or who adopt culturally responsive pedagogies are more likely to design lessons that leverage local materials and practices. Conversely, lack of training, heavy curriculum and assessment pressures, and limited documented examples of local materials in curricular guides act as barriers. This situational complexity means teachers’ classroom practices vary widely — from occasional use of familiar objects to carefully designed lessons that systematically foreground local mathematical knowledge (Yip, 2024).
Recent empirical work provides evidence that culturally grounded lessons using indigenous games, artifacts, or measurement practices can produce measurable gains in student performance and participation, particularly in primary and lower-secondary grades. These studies also highlight process issues: the need for culturally safe collaboration with community knowledge-holders, co-creation of materials, and careful alignment of local examples with targeted learning objectives so that cultural integrity and academic rigor are both maintained (Xu & Ball, 2024).
Despite growing interest and positive case evidence, gaps remain. There is limited systematic documentation of how teachers in mountain high schools identify, adapt, and assess indigenous materials for teaching specific mathematics topics. There is also insufficient research on the supports teachers need (policy, training, resource design, community partnerships) to sustain such practices at scale and across varied mountain contexts.
Addressing those gaps is essential for designing teacher education programs and policy supports that enable culturally relevant mathematics instruction without sacrificing the curriculum’s learning goals (Luzano, 2025).
