ETHNOMATHEMATIC EXPLORATION OF THE RANDAI DANCE IN MINANGKABAU CULTURE

Abstract

Combining a mathematical approach with culture is called ethnomathematics. Indonesia is a country that has abundant culture. Culture can be used as a medium for learning and can enable students to become more familiar with the culture itself. The purpose of this research is to explore the basic mathematical concepts contained in Randai Dance, to find out mathematical concepts that can be put into practice in learning and to explore the educational values contained in the art of Randai Dance. This research is research using the literature study method. The results of the research reveal that in the context of Randai Dance, there are several elements of ethnomathematics that can be found, namely (1) patterns and symmetry, (2) rhythm and time calculations, (3) geometry in movement, (4) number calculations, and (5) patterns-patterns in costumes. The results of the research also reveal that there are educational values contained in the art of Randai Dance, namely barundiang (negotiating), bacarajosamo (working together), kaba, garak malingka and the practice of kato nan ampek. The mathematical concepts found can be applied to learning to explain abstract concepts in mathematics and to introduce cultural elements to students.
