Abstract

Numbers and Sets are mathematical subject matter that can be learned using context in life. One of the contexts that can be used is gamelan artifacts. Gamelan contains the values of local wisdom that have become part of the identity of the Indonesian nation.  Ethnomathematics sets and numbers in gamelan must be explored as contexts in related mathematical learning.  The study aims to explore ethnomathematics related to the sociocultural context of Gamelan, offering an alternative approach to mathematical learning on sets and numbers. Employing an interpretive ethnographic approach based on Alangui's framework, the study unfolds across two art studios and three schools in Indonesia, engaging karawitan art culturalists and junior high school mathematics teachers as key informants. Through observation, documentation, field notes, and interviews, our findings reveal that gamelan artifacts can enrich the teaching of sets and numbers with their various types, shapes, and sizes. Hence, the results offer a transformative perspective for teachers, preservice teachers, and mathematics educators to integrate gamelan artifacts into mathematics lessons.

Abstract

The current generation of young people faces significant financial challenges in an increasingly volatile global economy, highlighting the need for enhanced financial literacy education. While the OECD has recommended the integration of financial literacy into school curricula, a notable gap exists in the development of age-appropriate financial literacy content that aligns with students’ cognitive and developmental stages. This study addresses this gap by evaluating students’ financial literacy knowledge, with a particular focus on integrating financial concepts into mathematics education. Specifically, the research targets financial topics that are accessible and relatable to upper elementary school students, exploring how these concepts can be integrated into existing mathematics curricula. The study involved students from grades 4, 5, and 6, with data collected through interviews that were transcribed and analyzed using NVIVO software. Findings indicate that topics such as exchange rates, foreign currencies, cash transactions, and digital payment systems resonate with students' existing knowledge and personal experiences. Furthermore, the study underscores the importance of introducing foundational personal financial management skills, such as distinguishing between needs and wants and promoting saving habits, from an early age. However, it also highlights that more complex financial concepts, including regulatory frameworks, consumer protection, and data security risks, are not developmentally appropriate for elementary students. The results of this research offer valuable insights into the practical integration of financial literacy into mathematics classrooms, with potential implications for curriculum development. These findings contribute to the growing body of knowledge on financial literacy education, providing a basis for selecting relevant financial topics for school curricula and fostering a more financially literate future generation.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi dan mengidentifikasi etnomatematika dalam permainan kuartet Using, serta menerapkan kurikulum trivium berbasis permainan tersebut dalam pembelajaran materi statistika di Sekolah Dasar kelas 3. Eksplorasi dan identifikasi etnomatematika dilakukan dalam kerangka penelitian kualitatif. Pengumpulan data dilakukan dengan wawancara, observasi, dan dokumentasi. Analisis data dilakukan secara kualitatif. Data menunjukkan permainan kuartet Using memuat konsep membilang, himpunan, perbandingan, relasi, fungsi, persegipanjang, sudut siku-siku, hubungan antar garis, kekongruenan, peluang, dan statistika. Selain itu terdapat aktivitas berhitung, bermain, dan menjelaskan dalam permainan kuartet Using. Kurikulum Trivium diterapkan dalam pembelajaran pada Sekolah Dasar kelas 3 dengan responden sebanyak 19 siswa. Pengumpulan data dilakukan dengan observasi dan tes tertulis, sedangkan analisis data dilakukan secara kualitatif dengan menentukan persentase ketercapaian konsep. Implementasi dalam pembelajaran menunjukkan bahwa pencapaian konsep literacy dan technoracy hanya 78,95%, sedangkan konsep matheracy mencapai 94,74%. Artinya implementasi kurikulum trivium dalam pembelajaran belum optimal. Hal ini terjadi karena masih ada siswa yang belum bisa membaca dan menulis dengan baik.This study aims to explore and identify ethnomathematics in the Using quartet game, as well as apply the game-based trivium curriculum in learning statistics material in grade 3 elementary schools. The exploration and identification of ethnomathematics was carried out within a qualitative research framework. Data were collected through interviews, observation and documentation. Data analysis was done qualitatively. The data shows that the Using quartet game contains the concepts of counting, sets, comparisons, relationships, functions, rectangles, right angles, relationships between lines, congruence, opportunities, and statistics. In addition, there are counting, playing, and explaining activities in the Using quartet game. Trivium curriculum was applied in learning at grade 3 elementary school with 19 students as respondents. Data collection was done by observation and written test, while data analysis was done qualitatively by determining the percentage of concept achievement. Implementation in learning shows that the achievement of literacy and technoracy concepts is only 78.95%, while the concept of matheracy reaches 94.74%. This means that the implementation of the trivium curriculum in learning is not optimal. This happens because there are still students who cannot read and write well.
