Abstract

Motivasi merupakan salah satu faktor pendukung dalam mencapai prestasi belajar matematika. Motivasi sebagai penggerak melalui usaha, dapat berpengaruh positif terhadap prestasi belajar matematika siswa. Hasil observasi di SMK Teknik Anugerah Soe menunjukkan bahwa prestasi belajar matematikasiswa masih rendah. Penyebabnya yaitusiswa lebih senang bekerja mandiri, kurang berpartisipasi dalam aktivitas belajar serta kurangnya kreativitas guru dalam mendesain pembelajaran. Salah satu alternatif untuk mengatasi permasalahan di atas adalah dengan pembelajaran model kooperatif tipe TPS. Tujuan penelitian ini adalah 1) menghasilkan kajian tentang pengaruh motivasi terhadap prestasi belajar matematika siswa pada pembelajaran model kooperatif tipe TPS; 2) meningkatkan prestasi belajar matematika siswa pada pembelajaran model kooperatif tipe TPS. Penelitian ini menggunakan metode kuantitatif model pre-eksperimental dengan rancangan one group pretest- posttestdesign melibatkan satu kelas penelitian dengan teknik purposive sampling. Instrumen yang digunakan sebagai alat pengumpulan data adalah tes berupa soal uraian, angket dan observasi. Teknik analisis data dalam penelitian ini menggunakan uji regresi, uji t-sampel berpasangan dan skor gain. Hasil analisis menunjukkan bahwa 1) terdapat pengaruh motivasi terhadap prestasi belajar matematika pada pembelajaran model kooperatif tipe TPS; 2)terdapat peningkatan prestasi belajar matematika siswa pada pembelajaran model kooperatif tipe TPS yang berada pada kategori tinggi dengan rata-rata skor gain 0,76.

Abstract

ABSTRACT This research is the development of learning resource based on etnomatematics with the learning model of Project Based Learning (PjBL) on the building material of prism room. The purpose of this study is to determine the validity, practicality and effectiveness of etnomatematics-based learning resources. Learning resources are developed in the form of student books and student worksheets based on ethnomatematics construct the prism room. This research type is research and development by using Borg and Gall model. This research was conducted in Junior High School Christian 1 Soe with the culture used is the woven of West Amanuban society in the form of oko. The results of this study indicate that the source of learning developed valid with the average percentage obtained 92.5% and also practical use in learning mathematics with the average percentage of teacher response 86% and 95.5% student response. This learning resource is also effective based on post-test results indicating that the average test score in the experimental class is 76.96 far greater than the control class 61.70. The proportion of students' completeness in the experimental class is 83% complete classically. Based on the results of the calculation of normalized gain score known that the percentage increase in mathematics learning achievement class VIII Junior High School Christian 1 Soe after taught with the source of learning based on ethnomatematics with PjBL model is 60% are in the category of being.

Abstract

Mathematics is often perceived as a challenging subject by students, necessitating innovative instructional approaches that enhance conceptual understanding and contextual relevance. The ethnomathematics approach presents a valuable strategy by linking mathematical ideas to cultural practices, thus fostering more meaningful learning. This study focuses on exploring mathematical concepts embedded in the oko mama plaiting craft tradition of the Amanuban community in South Central Timor. Through a qualitative design with an ethnographic method, the research involved direct engagement with three local artisans selected purposively based on their expertise. Data collection was conducted through semi-structured interviews, field observations, and documentation, followed by triangulation to ensure data validity. The analysis uncovered a variety of geometric concepts found in the artisans’ practices. These include two-dimensional shapes such as squares, rectangles, parallelograms, rhombuses, triangles, trapezoids, and both regular and irregular hexagons and three-dimensional forms such as cubes, rectangular prisms, triangular prisms, and hexagonal prisms. Mathematical ideas involving perimeter, area, and volume also emerged through the measurement and structuring techniques used in plaiting. The study demonstrates that local cultural practices serve not only as expressions of heritage but also as rich sources of mathematical thinking. Findings highlight the potential of the oko mama craft to serve as a contextual learning resource for geometry education. This research contributes to the existing body of knowledge by offering a more comprehensive ethnomathematical analysis compared to earlier studies that focused narrowly on basic geometric forms and calculations.
