Ethnomathematics study in measurement of Bengkalis Malay community as mathematics resources for elementary school

Abstract

ABSTRACT This research seeks to explore the ethnomathematical study of measurements of the Bengkalis Malay community as a study of mathematics instructional material for elementary schools. The method used is an ethnographic study which is part of the qualitative research method. The data collection techniques were observation, interview, filed notes, and documentation. The results of this study indicate that there is an ethnomathematical notion on the measurement of the Bengkalis Malay community related to measurement material for elementary school, including in the topics of measuring length, weight, area, volume, and time. Those non-standard measurement units are still used and well-known in the community. In contrast, teachers and students at elementary schools only know some terminologies and do not frequently practice them in schools. Thus, the researchers recommend incorporating ethnomathematics of measurement activities from the Bengkalis Malay community as mathematics resources for learning mathematics in elementary school.
