Abstract

The implementation of ethnomathematics approaches that connect culture and mathematics education remains limited, despite the need to bridge mathematical concepts with real-world applications rooted in local culture. The Batak Parhalaan calendar, which incorporates arithmetic computations, has not been extensively explored within mathematics education. Prior studies often focus broadly on ethnomathematics without delving into specific cultural contexts, such as traditional calendars and their relevance to learning mathematics. This study addresses this gap by investigating how the Parhalaan calendar can be integrated into mathematics instruction to enhance students' understanding of mathematical concepts. Employing a qualitative descriptive approach, this research examines the Batak Ugamo Malim tribe's calendar system, calculates Parhalaan in relation to arithmetic, and analyzes it from a mathematical perspective. The results reveal the application of modulo arithmetic in Parhalaan, specifically the modulo 7 system, which reflects the 7-day week structure. Results reveal the application of modulo arithmetic in Parhalaan, specifically the modulo 7 system, reflecting the 7-day week structure. The formula X+Y−Z=S mod 7 harmonizes the traditional Batak calendar with the Gregorian system, providing a systematic method for determining days. Integrating this concept into mathematics education strengthens problem-solving, logical reasoning, and interdisciplinary understanding. Linking mathematics with cultural traditions fosters appreciation for local heritage, broadens perspectives, and raises awareness about preserving cultural diversity, thereby enriching the educational experience for students.

Abstract

Pembelajaran matematika di sekolah masih sering terasa abstrak dan kurang relevan bagi siswa karena minim keterkaitan dengan konteks kehidupan dan budaya mereka sehari-hari. Padahal, mengintegrasikan budaya lokal ke dalam pembelajaran matematika dapat menjadikan konsep-konsep abstrak lebih konkret dan mudah dipahami. Etnomatematika hadir sebagai pendekatan yang menjembatani konsep matematika formal dengan praktik budaya masyarakat, salah satunya melalui Kalabubu, kalung tradisional khas Nias Selatan yang menyimpan potensi matematis pada susunan, bentuk, dan polanya. Penelitian ini bertujuan untuk mengkaji konsep-konsep matematika yang terkandung dalam Kalabubu, menganalisis relevansinya terhadap pendekatan pembelajaran mendalam (Deep Learning), serta menginterpretasikan keterkaitannya dengan teori pembelajaran bermakna David Ausubel. Penelitian ini menggunakan metode kajian literatur dengan pendekatan deskriptif-kualitatif, yaitu menelaah dan menganalisis berbagai sumber ilmiah yang relevan dengan etnomatematika, Kalabubu, Deep Learning, dan teori Ausubel. Hasil kajian menunjukkan bahwa Kalabubu mengandung konsep geometri, pola, simetri, pengukuran, dan transformasi yang berpotensi dimanfaatkan sebagai sumber belajar matematika kontekstual. Selain itu, konteks budaya Kalabubu dapat berfungsi sebagai advance organizer yang menjembatani pengetahuan awal siswa dengan konsep matematika baru, sejalan dengan prinsip pembelajaran bermakna Ausubel. Pembelajaran matematika berbasis budaya semacam ini terbukti mendukung pemahaman konseptual yang lebih mendalam sekaligus menumbuhkan kemampuan berpikir kritis siswa, sehingga relevan dengan semangat pendekatan Deep Learning dalam kurikulum pendidikan saat ini.

Abstract

This study aims to develop a Project-Based Learning (PjBL) module integrated with ethnomathematics by utilizing Nian Gao (Chinese New Year cake) as a cultural artifact representing the geometric concept of a cylinder to enhance junior high school students’ conceptual understanding of solid geometry. The study employed a Research and Development (R&D) approach using the ADDIE model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The participants were junior high school students in Kelapa Gading, North Jakarta, Indonesia. Data were collected through expert validation sheets, student response questionnaires, classroom observations, interviews, and pre-test and post-test assessments. The data were analyzed using descriptive qualitative and quantitative methods based on mean scores and percentage analysis. The results revealed that the developed learning module obtained an average expert validation score of 4.56, indicating that it was highly feasible for classroom implementation. The implementation of the PjBL module actively engaged students in observing, measuring, and identifying the geometric elements of a cylinder through hands-on exploration of Nian Gao. This contextual learning approach significantly improved students’ conceptual understanding of solid geometry, enhanced their learning engagement and spatial reasoning, and encouraged meaningful learning experiences. Furthermore, integrating ethnomathematics into mathematics instruction fostered students’ appreciation of Chinese Indonesian cultural heritage, thereby supporting both mathematics learning and character education. Therefore, the developed ethnomathematics-based PjBL module is an effective and feasible instructional resource for promoting meaningful, contextual, and culturally responsive mathematics learning.

Abstract

Mathematics learning at the elementary school level often faces obstacles in visualizing abstract concepts, especially in the material of plane figures. Students tend to have difficulty in connecting theoretical concepts with real objects in the surrounding environment. This study aims to develop a project-based learning module by integrating an ethnomathematics approach through the exploration of Riau Malay Traditional House ornaments. The use of traditional ornaments was chosen as a contextual medium because it is full of unique and authentic geometric patterns. The research method used is Research and Development (R&D) using the ADDIE development model which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. Data collection was carried out through observations of traditional house ornaments, in-depth interviews with cultural experts and craftsmen, and validation by material and media experts before being implemented to 3rd grade elementary school students. The results of the study indicate that Riau Malay Traditional House ornaments, such as the Pucuk Rebung and Itik Pulang Petang motifs, contain very rich principles of plane geometry, including an understanding of triangles, trapezoids, parallelograms, and the concept of symmetry. The developed module has met high validity and practicality criteria. Furthermore, findings from the implementation phase indicate that students' active involvement in this cultural exploration project successfully increased their learning interest, facilitated their understanding of geometric concepts, and enhanced their spatial reasoning skills. Furthermore, this study demonstrates that the integration of local wisdom into the mathematics curriculum is not only effective as a pedagogical tool but also plays a crucial role in fostering students' love and pride for the identity and cultural heritage of Riau Malays from an early age
