Sustainable Numeracy Literacy Learning Based on Local Wisdom Through Digital Media: An Ethnomathematical Approach to Quality Education and Environmental Awareness

This paper introduces an integrated model of numeracy literacy learning that combines ethnomathematics, local wisdom, and digital media within a sustainability framework. The model responds to the urgent need for quality education that is not only technologically relevant but also culturally meaningful and environmentally responsible. Ethnomathematics provides a foundation for connecting mathematical concepts with everyday practices such as weaving patterns, indigenous measurement systems, and agricultural cycles, all of which demonstrate sustainable resource use and ecological reasoning. When supported by digital media such as mobile applications, interactive modules, or augmented reality these cultural practices can be transformed into engaging learning experiences that strengthen students’ mathematical literacy, creativity, and problem-solving skills. Beyond pedagogy, this approach directly aligns with Sustainable Development Goal (SDG) 4: Quality Education, while also contributing to SDG 11: Sustainable Cities and Communities through cultural preservation, and SDG 13: Climate Action by promoting ecological awareness. Policy implications include the need to embed culturally responsive pedagogy into national curricula, invest in teacher professional development, and expand equitable access to digital infrastructure. Overall, this study positions education as a vehicle for sustainability by demonstrating that integrating local wisdom and digital innovation can build resilient, inclusive, and environmentally conscious learning systems.
