Abstract

The Batak ethnic group has cultural diversity and is rich in the values of each culture, both in the products and processes, and cultural philosophies. The Batak ethnicity is divided into several sub-ethnicities, including Toba Batak, Karo Batak, Mandailing Batak, and Simalungun Batak. The distinctive characteristics of each ethnicity can be used as material for research by researchers to explore the elements of that culture. In the field of mathematics, culture can also be used as an object of study. The research method used in the present study is the systematic literature review (SLR) which is aimed at identifying, studying, evaluating, and interpreting research results by the topics being studied so that it will answer the research questions that have been determined. The results can be seen that the Batak ethnic cultural components have mathematical concepts in them such as, among others,  livelihood characters, traditional houses, traditional musical instruments, traditional foods, ulos cloth and ornaments. traditional dances, and traditional clothing. The mathematical concepts that are obtained from the exploration of Batak ethnic cultures include the concepts of lines, angles, congruence, spatial geometry, flat geometric shapes, spatial geometric shapes, geometric transformations, arithmetic sequences, and numbers. These diverse themes indicate that mathematics is our culture.

Abstract

This research was motivated by students' low mathematical connections and lack of knowledge about the local culture around where they live. This research aims to develop a student digital worksheet using the concepts of ethnomathematics and Realistic Mathematics Education following  the ADDIE procedure. A number of 30 students of year five in a primary school in Kudus District, Province of Central Java, Indonesia, involved in the study. The learning material used the local cultural object namely Menara Kudus. This bulding is part of muslim gathering venue and known its adaptation to the Hinduism as it was built during the era. A digital worksheet is defined as a set learning activity that can be accessed using electronic gadgets, like computer or smartphone. Validation of the development resutls included experts and students to collect data on the feasibility assessment of the digital worksheet which consists of assessments by material experts and media experts. In addition, the use of web based interactive worksheets at Menara Kudus based on Ethno–RME shows a significant increase in students' mathematical connections. This means that the Ethno–RME based Digital worksheet at the Menara Kudus was declared feasible and can be used in mathematics learning.

Abstract

Numeracy is an important competency that is measured by Asesmen Kompetensi Minimum (AKM/Minimum Competency Assessment). To improve student numeracy, innovation is needed in learning mathematics, one of which is by using Ethnomathematics. The cultural object that becomes the benchmark is     Rumah Gadang. Before producing effective and efficient models, devices, and learning methods based on the ethnomathematics of Rumah Gadang oriented to student numeracy, it is necessary to conduct a study first, so this research aims to conduct a literature review related to numeracy in the Rumah Gadang. The data collection method is a literature study, where the data is analyzed through three stages, namely Data Reduction, Data Presentation and Verification. Based on this research, it was found that the results of the researchers' contextual exploration of Rumah Gadang can be associated with 4 domains of mathematics material, namely numbers, geometry and measurement, algebra and data and uncertainty. Therefore, Rumah Gadang can be used as a learning material that is quite varied in terms of contextual in ethnomathematics-based mathematics learning, especially in terms of writing socio-cultural context questions in a numeracy assessment.

Abstract

This research aims to analyze ethnomathematics in a mosque named Gedhe Kauman in Yogyakarta. The ethnomathematics studied is related to the mathematical concepts of area and perimeter of two dimensional shapes. This research is qualitative research with an ethnographic approach. The data source in this research is the result of direct observation and documentation by the researcher. Data collection techniques were carried out by observing and documenting mosque buildings. Testing the validity of the data was carried out using technical triangulation. The subject of this research is the historic building of the Gedhe Kauman Mosque. Based on the research results, it was found that the Mosque building is quite closely related to ethnomathematics learning resource. This is proven by the presence of geometric elements in the structure and contents of the building that have easyly reognized patterns. The geometric shapes found are squares, rectangles, circles, triangles and trapezoids. These plane shapes can be integrated into the mathematical concepts of perimeter and area for learning elementary mathematics. This instructional approach might evoke student's disposition towards mathematics.

Abstract

This study aims to develop problem based learning in ethnomathematics-based textbooks through Sego Boranan's buying and selling activities to improve students' problem-solving abilities in social arithmetic material. Research & development were carried out a procedure of 3D (Define, Design, & Develop). The feasibility assessment was carried out by experts and practitioners using the feasibility sheet, the readability assessment by students who had obtained Social Arithmetic material using readability sheets, and student responses by students who were studying Social Arithmetic material using a student response questionnaire. The textbooks developed were included in the very feasible criteria, was easy to understand, and very feasible to be implemented in learning mathematics. Although it is suggested that using an experimental method can test the  effectiveness of using this textbook on learning outcomes and students' problem-solving abilities, this paper presented examples of ethnomathematics problem solving that can be practically implemented in mathematics classrooms.
