Abstract

This study aimed to explore mathematical concepts in the local culture known as ethnomathematics. The culture examined in this study is the Serampang XII Dance performance, originating from the Deli Malay ethnic group in the province of North Sumatra. This qualitative descriptive research adopts an ethnographic approach, revealing and describing local cultural facts discovered in the field. It is revealed that the Serampang XII Dance performance incorporates various applications of mathematical concepts, including basic counting, geometric angle concepts, geometric transformation concepts, set concepts, relation concepts, and flat shape concepts. This research aims to provide answers to its main question, which is, "What mathematical concepts can be identified and further explored in the Serampang XII Dance performance?". In conclusion, Serampang XII Dance can be considered an ethnomathematical innovation that can be used as a foundation for a new mathematics teaching approach with the hope of transforming the perception of mathematics education from monotony to enjoyment.

Abstract

The phenomenon of students experiencing stress in learning mathematics is commonplace in this era of globalization. It is not uncommon for students to feel afraid when facing material or assignments presented by teachers at school. Therefore, this research aims to identify stress-coping strategies used by high school students in dealing with mathematics learning based on gender. This research uses descriptive quantitative methods. Data was obtained through a questionnaire containing 46 statement items, then distributed via Google Forms and statement sheets to students. The research respondents consisted of 89 students from tenth graders in one of the high schools in Tambun Selatan, Bekasi, West Java. Data analysis was carried out using the stress-coping percentage method. The research results show that both male and female students tend to use emotion-centered coping strategies, with a percentage of male respondents was 57% and female respondents had a percentage of 79%. Also, the coping strategy section that focuses on emotions tends more towards the sub-indicator of accepting responsibility with a percentage of 76% for male students and 78% for female students. It can be said that there is no difference between male and female students in solving a problem.

Abstract

This study explains the steps in developing mathematical comics and the practicality of using comics in learning mathematics for junior high school students. The aim of this research is to create ethnomathematics-based comic learning media that focuses on number pattern material. The method in this research was the development method (Research and Development) with a 4D model (Define, Design, Develop, Disseminate). The research subjects were 28 class VIII junior high school students. Data collection techniques were carried out through interviews, observation, and questionnaires. The research results showed an average of 92.11% with a validity test score by material experts of 91.34%, while for media experts it was 95% and products that had been validated were then tested on students with results of 90%. Based on the assessment of instructional quality in trials with students, learning media was also stated to be in the very practical category, so that learning media can be used to help the mathematics learning process in schools.

Abstract

Ethnomathematics is a field that studies how people from different cultures understand, interpret, and use mathematical concepts. Traditional clothing is one of the cultural characteristics of the local community. The motifs on Malay traditional clothing depict symbols, ideas, and techniques of plane figures, often used intuitively by seamstresses. These motifs can be found in various Malay traditional garments and have a connection to ethnomathematics, particularly in measuring activities and mathematical concepts based on two dimensions. Therefore, the purpose of this study was to explore the elements and concepts of plane figures in Malay traditional clothing patterns through an ethnomathematics perspective. This research employs qualitative methods, with data collection conducted through observation, interviews, documentation, and literature review. The study was exploratory in nature, utilizing an ethnographic approach. The findings reveal that the motifs in Malay traditional clothing patterns, which include elements and concepts of two-dimensional shapes such as rhombuses, circles, triangles, and squares, can serve as a valuable learning resource for understanding two-dimensional geometry.

Abstract

Mathematics plays an important role in various areas of daily life and helps develop logical, critical, and systematic thinking patterns, and problem-solving abilities. However, the mathematics learning process often experiences obstacles both from internal factors such as students' negative attitudes, low interest in learning, and weak motivation, as well as external factors such as lack of teacher focus and minimal family support. Ethnomathematics, namely mathematics integrated with local culture, has emerged as an effective method to help students understand mathematical concepts more easily and interestingly. This research was conducted on the process of making Sidikalang coffee at UD (trading business) Kopi Keke, Dairi, North Sumatra, which combines ethnomathematics with mathematics learning. Through qualitative methods with an ethnographic approach, this research identifies mathematical concepts contained in the six stages of coffee making, namely drying, pounding, roasting, grinding, packaging, and marketing. The research results show that this process includes the concepts of social arithmetic, calculation, time comparison, plane geometry, space geometry, and measurement so that it can support mathematics learning that is easy for students to understand.
