Abstract

The low mathematical literacy skills of junior high school students in Indonesia, especially those living in the Small Border Islands, require serious attention from various stakeholders. Improving students’ mathematical literacy is a shared responsibility that can begin with introducing the form of PISA mathematical literacy questions to junior high school students. One effort to achieve this is through an ethnomathematics-based mathematical literacy competition. This competition aims to provide knowledge and understanding of PISA mathematical literacy to students in the Small Border Islands, particularly on Moa Island. The activity was carried out as a form of community service by lecturers and students, consisting of four stages: initial observation, socialization, implementation, and evaluation. The participants of this competition were students from seven junior high schools on Moa Island, with a total of 57 participants. The increase in participants’ knowledge regarding PISA mathematical literacy question forms was measured using a questionnaire. The results showed an improvement in participants’ understanding before and after participating in the competition. However, test data also indicated that the mathematical literacy skills of students on Moa Island remain relatively low. Therefore, sustainable programs are needed to improve the mathematical literacy skills of students in the Small Border Islands, including Moa Island.

Abstract

Ethnomathematics connects mathematical concepts with cultural practices, making learning more contextual and meaningful. However, studies in small border islands remain limited, despite their rich cultural heritage. One example is Koli leaf weaving on Letti Island, which reflects mathematical ideas in daily life. This study aims to conduct an ethnomathematical study of Koli leaf-woven objects on small border islands using a qualitative ethnographic approach that includes literature review, observation, interviews, and documentation. The collected data is analyzed using content analysis, thematic analysis, and pattern recognition. The findings reveal that Koli leaf weaving involves mathematical concepts, including plane shapes (triangles, circles, hexagons) and solid shapes (hexagonal prisms, cylinders). These findings imply that local cultural artifacts can serve as contextual learning resources in mathematics and science education. The geometric patterns of Koli leaf weaving can be used in geometry lessons to strengthen students’ mathematical literacy, critical thinking, and appreciation of local culture. This research also has implications for the preservation of local knowledge and the development of culture-based mathematics education on small border islands.
