Abstract

Mathematics exists as rooted in human ideas, ways, and techniques to respond to their environments. Along with its development, mathematics has been taught through formal education or schooling in the flat- not flexible ways and far from students' social and cultural lives. Indonesia is rich with culture, including the Special Region of Yogyakarta (DIY). It is called a city of culture. Educators are not yet aware of this richness in the learning process to integrate it as the starting point. It is hard to find in mathematics textbooks in Indonesia, which put cultural context as starting points. Therefore, this study aims to explore Yogyakarta's culture in terms of contexts used in mathematics learning.  It is an ethnography study. Furthermore, the data was collected through literature artifacts, field observation, and interviews with resource persons who understand the seasons, system, and calculation of birth and death days. It is to clarify the researcher's understanding of the literature. This study showed that Yogyakarta's people use mathematical modeling to determine the seasons' system and funerary dates. These models have the potential to be used as a starting point in learning mathematics.

Abstract

This study aims to investigate ethnomathematics research trends through bibliometric analysis on widely distributed Google Scholar (GS) and Scopus databases. One thousand seventy-seven papers were reviewed from GS and Scopus databases searched using Harzing's Publish on 9 January 2023. A descriptive study approach was used to investigate the data. The result of this study is that the number of ethnomathematics studies has increased over the last decade (2012-2022). The most productive author based on GS is Rosa from Brazil, and the full author based on Scopus is Widada from Indonesia. The principal authors with the highest citations are Ascher, based on GS, and Muhtadi, based on Scopus, with the highest citations. The Journal of Physics: Conference Series (JPCS) in the last decade is the most crucial source of ethnomathematics documents. Based on VosViewer visualization, Rosa is the author who has the most co-authorship papers and total link strength. The VosViewer displays four clusters related to Ethnomathematics: mathematics education, skills, ethnomathematics studies, and geometry. Our strong recommendations regarding this study are ethnomathematics research related to literacy, numeracy, technocracy, and mathematical abilities. The results can assist relevant researchers in understanding trends in ethnomathematics research and recommend guidelines for other studies.

Abstract

Traditional game (TG) Galah Asin has been played for generations—a game cultivated from generation to generation for Timor Tengah Selatan residents, Indonesia-Timor Leste Border Area. People must be aware that Galah Asin's TG and activities contain mathematics concepts that can be employed in math study. This study examines ethnomathematics in Galah Asin, a conventional game in Mnelalete Village, West Amanuban District, South Central Timor Regency, NTT Province, Indonesia. An ethnographic approach was used to investigate the data. Ethnomathematics emphasizes understanding a culture's concepts, methods, and practices from its members' perspectives. The study collects data through observation, interviews, and documentation. This study analyzed data using taxonomy, domain, componential, and cultural theme analysis. The study results found flat, translational, reflecting, line, angel, and congruence geometry ideas in the game arena, body movement, and player position of Galah Asin. Galah Asin also has addition, subtraction, multiplication, and division in gameplay. The implication of exploring ethnomathematics study is that understanding cultural activities can be integrated into school mathematics instruction. In addition, the ethnomathematics exploration of TG impacts the preservation of local culture.
