Abstract

Nowadays, mathematics learning is becoming less favored by students, as mathematics is often considered the most difficult subject to understand. In fact, we know that almost all aspects of life involve mathematical knowledge. Based on several interviews conducted with junior high school students in Ruhui Rahayu Village, nearly 60% of students stated that they did not like mathematics, and their exam scores in this subject were below the minimum passing grade (KKM). As an educator, I felt challenged to carry out a community service program related to mathematics learning for these junior high school students in Ruhui Rahayu Village. From the community service activities we conducted, it turned out that the students' abilities in geometry (specifically in solid figures) showed improvement. Additionally, the students developed a greater interest in learning mathematics. Teaching mathematics using the "GO Fun" (Geometri Fun) media proved to be far more engaging and enjoyable. It can be concluded that there was an increase in students’ interest in learning mathematics: initially, only 60% of the 20 students who struggleKeywords: Learning, Mathematics, Go Fun Media

Abstract

Ethnomathematics is a branch of science that studies the relationship between mathematics and cilture, including traditions, arts and social life. This research aims to reveal the mathematical concepts contained in traditional Dayak clothing, especially in their geometric motifs and patterns. The method used is a qualitative approach with ethnographic analysis of traditional clothing artifacts, interviews with traditional leaders, and literature studies. The research results show that Dayak traditional clothing contains various mathematical concepts, such as symmetry, geometric transformations (rotation, translation, reflection), and fractal patterns. Symmetry is found in the arrangement of the carved motifs, while repetition and fractal patterns can be seen in ornamental details such as the distinctive tendrils of leaves and flowers. This research shows that the cultural heritage of the Dayak tribe not only has aesthetic value, but also educational value which can be developed as contextual mathematics teaching material. It is hoped that these findings will increase understanding of the relevance of mathematics in everyday life and promote the preservation of local culture.

Abstract

This study examined the effect of Student Teams Achievement Divisions (STAD) cooperative learning supported by student worksheets on seventh-grade students’ mathematical problem-solving ability (MPSA) in a numeracy context. A quasi-experimental non-equivalent control group pretest–posttest design was used, with one class assigned as the experimental group and another as the control group. Data were collected using essay-type pretest and posttest instruments scored using four indicators derived from Pólya’s problem-solving framework: understanding the problem, devising a plan, carrying out the plan, and looking back. Data were analysed using descriptive statistics and analysis of covariance (ANCOVA), with pretest scores treated as a covariate. ANCOVA results showed a significant effect of instructional group on posttest MPSA after controlling for initial ability, and the pretest covariate significantly predicted posttest performance. Indicator-level ANCOVA indicated that the strongest group differences occurred in understanding the problem and devising a plan, while no significant difference was found for carrying out and checking the solution. These findings suggest that STAD supported by worksheets contributes particularly to students’ early-stage problem-solving processes in numeracy-oriented mathematics learning. Results should be interpreted cautiously due to the non-randomized design and limited number of test items. Keywords: cooperative learning, numeracy, problem-solving, student teams achievement divisions, worksheet.   Penelitian ini mengkaji pengaruh pembelajaran kooperatif tipe Student Teams Achievement Divisions (STAD) yang didukung lembar kerja siswa terhadap kemampuan pemecahan masalah matematis (KPMM) siswa kelas VII dalam konteks numerasi. Penelitian menggunakan desain kuasi-eksperimen non-equivalent control group pretest–posttest, dengan satu kelas sebagai kelompok eksperimen dan satu kelas sebagai kelompok kontrol. Data dikumpulkan melalui tes uraian pretest dan posttest yang dinilai menggunakan empat indikator yang diturunkan dari kerangka pemecahan masalah Pólya, yaitu memahami masalah, menyusun rencana penyelesaian, melaksanakan rencana, dan memeriksa kembali penyelesaian. Analisis data dilakukan dengan statistik deskriptif dan analisis kovarians (ANCOVA) dengan skor pretest sebagai kovariat. Hasil ANCOVA menunjukkan adanya pengaruh signifikan kelompok pembelajaran terhadap skor postest KPMM setelah mengontrol kemampuan awal, dan skor pretest berkontribusi signifikan dalam memprediksi skor postest. Analisis ANCOVA per indikator menunjukkan perbedaan paling kuat pada indikator memahami masalah dan merencanakan penyelesaian, sedangkan pada indikator melaksanakan dan memeriksa kembali penyelesaian tidak ditemukan perbedaan signifikan. Temuan ini mengindikasikan STAD berbantuan lembar kerja terutama mendukung tahapan awal proses pemecahan masalah dalam pembelajaran matematika berbasis numerasi. Hasil perlu ditafsirkan hati-hati karena desain non-random dan jumlah butir soal terbatas.  Kata kunci: kemampuan pemecahan masalah, lembar kerja siswa, numerasi, pembelajaran kooperatif, student teams achievement divisions.
