Exploring Ethnomathematics with Ethnomodeling Methodological Approach: How Does Cigugur Indigenous People Using Calculations to Determine Good Day to Build Houses

Abstract

This article discusses Cigugur indigenous communities' custom in carrying out calculation practices to determine the best time to start house construction activities. The realist ethnography approach was used in this study through exploratory research. The ethnomathematics design adopted four elements: generic questions, initial answers, critical constructs, and specific activities. Ethnomodelling was used to translate cultural mathematics ideas into academic mathematics through ethical, emic, and dialogical approaches. Based on ethnomathematics, the community practices the dimensions of necessary universal mathematical activities, such as counting, placing, and explaining. Based on ethnomodeling, mathematical ideas and practices carried out are relevant to the concepts of enumeration, integer operations, sets, relations, congruence, and modulo. The study results recommend the importance of ethnomodelling as a methodological approach to ethnomathematics to create and develop didactical situations, especially in developing a new lesson.

Mathematical Dimensions of Amenama Man Wankyo Children Play of the Tiv People of Iyon Shangev-Ya in Kwande Local Government Area of Benue State, Nigeria

“…Elly (2021) stated that most traditional games contains such mathematical concepts as length, height, depth, to name a few for traditional games in Northern Nigeria, most of them include the concepts of algebra, set theory, geometric coordinates, arithmetic progression, geometric progression, matrices, probability and many other concepts in mathematics. Most of these have been inherent in the culture and traditions of the tribes (indigenous people) in accordance with Umbara, Wahyudin and Prabawantos (2021) notion that people's cultural activities are carried on from generation to generation, including estimating, patterning activities, and building geometric patterns. To this effect, Nkopodi and Mogege (2009) described indigenous knowledge system (IKS) as a systematic body of knowledge acquired by local people through the accumulation of experiences, informal experiences and intimate understanding of their environment in a given culture.…”

Networking Between Ethnomathematics, STEAM Education, and the Globalized Approach to Analyze Mathematical Connections in Daily Practices

“…Also, there are studies focused on recognising the measurements used in the elaboration of cassava buns (Rodríguez-Nieto et al, 2019a), works inspired by the mathematical richness implicit in masonry (Rey & Aroca, 2011), calculation practices by indigenous people of Cigugur to determine the best time to start housing construction activities, identifying arithmetic operations, sets, congruences, etc. (Umbara et al, 2021). Castro et al (2020) inquired about the mathematical notions developed by a carpenter in the making of furniture and ships, highlighting the use of the metre, centimetre, inch, and tolerance.…”
