Abstract

Ethnomathematics, an interdisciplinary field at the intersection of cultural studies and mathematics, examines the intricate mathematical practices found within diverse cultural settings. This research focuses on Rangku Alu, a traditional game from Indonesia, to explore its embedded mathematical elements. Using a qualitative ethnographic methodology, the study uncovers the mathematical concepts within the game's cultural context. It traces the origins and cultural importance of Rangku Alu in Manggarai, East Nusa Tenggara, through combining participant observation, interviews, and literature review. The game, which prominently features bamboo, is a staple activity in harvest celebrations and serves as a way to express gratitude. During the game, players engage in synchronized movements that create rhythmic patterns and interactive sequences. The analysis reveals seven distinct numerical patterns, derived from the strikes of bamboo, jumping sequences, and player formations. These patterns include both odd and even sequences, as well as basic arithmetic operations. Rangku Alu not only entertains but also provides a unique setting for exploring numerical concepts. This study highlights the potential of integrating traditional practices like Rangku Alu into mathematics education to promote inclusivity and enhance mathematical understanding in multicultural environments.

Abstract

The integration of cultural and realistic contexts in mathematics learning has shown significant potential in fostering critical thinking skills; however, existing educational resources often lack a comprehensive approach that effectively combines these aspects. Addressing this gap, this research aimed to develop a novel Ethno-Realistic Mathematics Education (Ethno-RME)-based three-dimensional learning module that meets the criteria of validity, practicality, and has a positive impact on students' critical thinking skills. Utilizing a Design Research methodology, specifically a development study, the research was conducted in two stages: Preliminary Evaluation and Formative Evaluation, involving 12th-grade students from SMAN 5 Purworejo as participants. Data collection included product quality assessment sheets evaluated by material and media experts, student response sheets, and critical thinking test instruments. The results demonstrated that the module achieved high validity, with content rated "Good" (average score: 141 out of 175) and media rated "Very Good" (average score: 131 out of 135). Practicality was confirmed through student responses, with small group and field test average scores classified as "Very Good" (72.33 and 72.36, respectively). Furthermore, post-test results for critical thinking skills revealed an average score of 75.51, indicating the module’s potential to enhance students’ critical thinking. These findings establish the Ethno-RME-based module as a valid, practical, and impactful teaching resource, offering a culturally relevant and application-oriented alternative for mathematics education.
