Watu Gatheng Kotagede: A Gateway To Higher Order Thinking Skills In Primary School Mathematics Through Technology-Based Ethnomathematics

Abstract

This study aims to explore the feasibility of developing technology-based mathematics learning media that integrates the ethnomathematics context of Watu Gatheng Kotagede. The background of this study is the low quality of mathematics teaching at the primary school level, particularly in the development of Higher Order Thinking Skills (HOTS) , which is partly due to the lack of learning media relevant to local culture. Watu Gatheng, as a traditional practice of arranging stones, is rich in mathematical concepts such as geometry, patterns, logic, and reasoning. Using a qualitative approach with a preliminary research design , data was collected through a literature review, in-depth observation, and interviews with elders and craftsmen in Kotagede. The collected data were then analyzed thematically to identify relevant mathematical patterns and concepts. The research results show that Watu Gatheng practices are an extraordinary ethnomathematical resource. These concepts, which are passed down through practice and local wisdom, have great potential for integration into learning media. These findings form a strong foundation for the development of an application prototype using iSpring Suite technology, which can present the material interactively and engagingly. Expert validation by specialists in mathematics, culture, and education indicates that the Watu Gatheng concept is highly suitable for adaptation into HOTS-oriented educational media. The conclusion of this research is that Watu Gatheng Kotagede ethnomathematics is an effective and relevant content source for developing innovative and HOTS-oriented mathematics learning media.
