In cultural responsive learning, teachers need to have the ability to explore mathematical phenomena in cultural elements as learning content. This research is a qualitative descriptive study aimed at exploring ethnomathematics in Bajawa traditional dances, namely the Ja,i dance, its relevance to competency standards and basic mathematics competencies in elementary schools. The approach used is ethnographic. The technique used is observation and study of documents and the researcher himself acts as the main instrument. Observations were made on the accompanying music devices contained mathematical concepts. Furthermore, researchers compare with the basic competencies of elementary school mathematics. The results showed mathematical material was found in the musical instrument section of Ja,i dance. The surface of the gong and the drum (gendang) are circular, the body of the large drum is frustum of a cone, and the gendang laba kagu, laba bhuga and gong are tube-shaped. In the middle of the gong there is a kind of lump which is shaped like a half ball. The implementation of this research can be applied in cultural responsive learning in elementary schools.Keywords: ethnomathematics, learning, cultural responsive, jai,i dance
This article aimed to explore ethnomathematics in the Malind tribe to strengthen the character values of elementary school students. The method used descriptive survey method with data collection techniques such as observation, interviews, and literature review. The researchers act as a human instrument. The qualitative data were obtained and then analyzed by paying attention to ethnomathematics material or theme. The results showed: firstly, ethnomathematics in the culture of the Malind tribe was found in activities of daily life such as the manufacture of farming tools, hunting, fishing, musical instruments, noken, ornaments and paintings, traditional ceremonies, life behaviors, and traditional games. Second, the attitude of responsibility, like to work hard, practice religious values, develop creativity, friendship, responsibility, the spirit of cooperation and kinship and tolerance is an integrated national character in the cultural values of the Malind tribe. Ethnomathematics can be integrated into learning mathematics in elementary schools Keywords: Ethnomathematics, Malind Tribe, Education Character
The purpose of this study was to describes the use of student’s contribution as a transition tool at each level of learning the fraction operation concept. This study involved fourth grade students of an elementary school in Ngada East Nusa Tenggara. The type of this research is Design Research with three stages, namely: initial design, teaching experiment and retrospective analysis. This research begins conduct a hypothetical learning trajectory (HLT) of fraction operations concept. The HLT has been tested before the actual learning process (ALT). The results of the retrospective analysis obtained an overview of the Actual Learning Trajectory (ALT) show that the use of various student’s contribution at each level of learning can lead to understanding the fraction operation concept.
The objectives of this study are: 1) to know the implementation of cooperative learning model of STAD type in mathematics learning in class V students in SDI Blidit, Waigete, Sikka Regency, 2) to find out the improvement of students' learning outcomes after applying cooperative learning model of STAD type on mathematics learning in class V students in SDI Blidit, Waigete, Sikka Regency. This research is a type of Classroom Action Research (CAR) by using a qualitative approach. The subject in this study was the V-grade SDI Blidit student, numbering 20 students. The techniques of data collection in this study were observation, interview, test and documentation. Based on the results of the data analysis and the discussion of the results can be concluded that the results of the study of class V students in mathematics after implementation the cooperative learning model of STAD type in cycle I has not reached the complete learning. It can be seen from the number of students who reached the KKM or minimal completeness criteria is 6 people (60.5%) of 20 students, while in cycle II has undergone an increase by an overall percentage of 86%. Teacher and student activities also increased from cycle I to cycle II; (56.15%) in cycle I and (84.61%) in cycle II with its criteria is very good. While the student activity cycle I (50%) and cycle II (87.7%) are in excellent criteria. Based on the results of the interviews, it can be concluded that students are motivated when learning materials are implemented using the STAD type Cooperative learning model.
This study aims to determine the ethnomathematics in the process of making Kedang woven fabrics. The approach used is qualitative ethnographic research. The subjects in this study consisted of two Kedang weavers. The data collection process used observation, interview, and documentation techniques. Data were analyzed descriptively qualitatively. The results showed that there are mathematical concepts that can be observed in the process of making Kedang woven fabrics, namely integers, geometric concepts namely points, angles, lines, rectangles, and blocks, truncated cones and spheres. Thus the process of weaving Kedang woven cloth can be used as the content and context of elementary school mathematics learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
