Abstract

The weaknesses in students' abilities in applying mathematical concepts and rules to non-routine problems caused them difficulties in solving them. This study was aimed at analyzing students' numeracy skills in solving proportion problems with the contexts of Candi Umbul Traditional Market. The study was qualitative descriptive research involving two seventh-grade students in Indonesia as research subjects. The two student subjects were selected from 10 students who completed the numeracy task, one with the most correct answer and one with the most incorrect answer. The ten students who completed the numeracy task were the ones with the highest test scores among 32 students in the topics of proportion and social arithmetics. The research instruments used in the study were students' work sheets (in the form of essay tests) and interviews. The data analysis technique used was descriptive analysis. Findings show that not every student with high math scores had high numeracy skills. This is evident from the fact that students faced problems when completing proportion items in the context of Candi Umbul Traditional Market; they encountered difficulties in solving the problems. The results of this study are expected to serve as a reference for further research on students' numeracy skills.

Abstract

Learning in measuring units of length is basically inseparable from familiar objects in the society, one of which is traditional songs. This study was aimed at finding whether using the tune of a traditional song in Yogyakarta, namely Pocung song, and modifying the lyrics with mathematical contents can facilitate students to think mathematically. This study used the pre-experimental design method with the one-group pre-test-posttest design model. The research subjects were 10 3rd grade students of a cultural elementary school in Gunungkidul. The results showed that the modification of the Pocung song in ethnomathematics-based mathematics learning in the length-unit competencies was developed in an audio-visual form which could be accessed via the YouTube and the implementation ofthe Pocung song modification in ethnomatematics-based learning in the length-unit competencies had a positive influence on students’ learning achievements.

Abstract

Toraja is one of the tribes in South Sulawesi, precisely in Tana Toraja. The Tana Toraja people are very famous for their strong cultural customs; there are so many spiritual activities, a series of traditional ceremonies, and cultures that are still very well preserved among the local community. Tongkonan is a Torajan traditional house building that is very popular and always attracts attention, including people from outside Tana Toraja, because the shapes and motifs of the carvings are unique; the shapes and motifs of these carvings cannot be separated from mathematical elements. This study is aimed at identifying  the ethnomathematics contained in the carving patterns of the Tongkonan traditional house building. The research was qualitative with a descriptive method. The data collection technique used was a literature study. Results indicate that ethnomathematics in the structure of carving patterns on the Torajan traditional houses building can be integrated into various models of mathematics learning.

Abstract

The main foundation of ethnomathematics is an awareness of the many ways of knowing and doing mathematics that relate to the values, ideas, notions, procedures, and practices in a diversity of contextualized environments. The ethnomathematical practices of the Agta Tabangnon refer to the form of varying mathematical concepts that are embedded in their cultural practices. This paper presents the results of the efforts in documenting the ethnomathematics of the Agta Tabangnon in Sitio Ruras, Barangay Hiwacloy, Goa, Camarines Sur, Philippines. The significant contributions and challenges relative to their ethnomathematical concepts and cultural practices were also discussed. The Agta Tabangnon is a society that manifests stable cultural practices that capture and address every facet of their daily lives. Their ethnomathematics are instances of cultural practices that are passed down from generation to generation and have had a significant impact on society. Their ethnomathematics and cultural practices are the way their cultural group mathematizes their own realities in order to survive earnestly, so learning their practices is one way for us to embrace cultural diversity in our increasingly interconnected world.

Abstract

The panorama of ethno-education is compromising for the 115 native indigenous ethnic groups from Colombia, bearing in mind that some educational institutions have not advanced in the incorporation of their own knowledge in their intercultural curricula. The aim of this qualitative tradition (Educational Action Research) study was to implement a bilingual (Ebera-bedea/Spanish) Intercultural Technological Element (ITE) by using Geogebra in order to teach the concept of proportionality in an indigenous reservation of the ethnic group Emberá-Chamí. 13 students of basic secondary education belonging to ethnic group were included. Firstly, a diagnostic evaluation was performed to assess the initial knowledge of the students about the concept of proportionality in their own native language. Then the ITE was designed and applied to the students. The students were evaluated on three aspects (1) on their own knowledge, (2) on the affective and emotional aspect and on (3) their conceptions. In general, the students were able to contemplate the relationship between the topic developed (proportionality) and the activities of the culture with a reception of 77%. Regarding the emotional aspect 62% of the students see the solution of the guides as favorable since it promotes individual work as well as responsibility, and the other 38% perceive it moderately. On the other hand, the worldview and cosmogony conceptions were achieved in the 84% of the students.

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

Culturally-based mathematics learning becomes an important alternative to overcome students' learning difficulties. One relevant cultural product is Jepara Carving Art, which contains geometric concepts as part of ethnomathematics. This study aims to describe the mathematical concepts embedded in Jepara carving art and implement them as an alternative culturally-based mathematics learning method. Using a qualitative approach, data were collected through interviews, observations, and field notes, with the research subjects being Jepara carving artisans. The results show that the mathematical concepts integrated into Jepara carving art include points, lines, angles, slopes (gradients), plane geometry, circles, solid geometry, congruence, and geometric transformations such as reflection and rotation. Additionally, the ethnomathematics of Jepara carving art can be implemented as an alternative culturally-based mathematics learning method, where several ethnomathematical activities relate to school mathematics materials. These findings emphasize the importance of linking local culture with mathematics learning to enhance students' understanding. Therefore, this study recommends the inclusion of Jepara carving art in the curriculum as an effective strategy for culturally-based 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.
