An ethnomathematics study of the days on the Javanese Calendar for learning mathematics in elementary school
Öz
Ethnomathematics is a mathematical value that presents in a culture. Calendar as a system of time periods is ethnomathematics. The calendar has days, dates, months, and years. Likewise, the Javanese calendar has years, months, dates, days (7 cycles on a week), and also pasaran (5 cycles on a week at the Javanese). The use of days in the Javanese calendar can be used as contextual and enrichment material in learning mathematics. This study aims to reveal the ethnomathematics values on days of Javanese Calendar as mathematics learning material. It uses qualitative methods that follow the ethnomathematics study framework. We took data from the indigenous community at Yogyakarta, Indonesia. Data collection techniques use interviews with traditional elders, and document analysis of Javanese Primbon (the special of Javanese Book) and mathematics curriculum content. The data analysis is determined by relational ideas of the days on Javanese Calendar, and the mathematics curriculum content. The result shows the ethnomathematics value of the remainder and modulo associated with days in the Javanese Calendar. Based on the results, the days on Javanese Calendar can be incorporated in mathematics learning material. Elaborating the days on Javanese Calendar is the potential for connecting culture and mathematics in the classroom. The days on Javanese Calendar contain mathematics values, and close to students' thoughts, so it can be used in elementary school mathematics class to make learning mathematics more meaningful.
