Studi Etnomatematika: Garis dan Sudut Pada Kerangka Tulang Ikan Paus di Kabupaten Lembata

Abstract

Mathematics is a subject that is considered difficult and boring for students. Mathematics is considered difficult and boring because it involves lots of numbers and formulas. In addition, the learning process factors in the classroom are too theoretical and less contextual which makes students bored. Lessons in class are sometimes found to be different from math problems in everyday life. One aspect that can be developed for learning innovation is connecting mathematical concepts with the culture of the local community using an ethnomathematics approach. Ethnomatematics is an approach that connects mathematical concepts with the culture that exists in everyday people's lives. This study aims to describe the relationship between the mathematical concepts of lines and angles and the skeleton of a whalebone in Lembata District. This research is a type of qualitative research with descriptive exploratory method. The subject in this study was the whalebone skeleton located in Lembata Regency. Data collection techniques used in this study are observation, interviews and documentation. Based on the results of the research that has been done, it is concluded that there are mathematical concepts of lines and angles in the whalebone framework which include straight lines, curved lines, parallel lines, right angles, acute angles and obtuse angles.
