Abstract

Mathematics is often perceived as abstract and disconnected from students’ daily lives, yet ethnomathematics highlights that mathematical ideas are embedded in cultural practices. This study explores the ethnomathematical concepts found in the preparation of Ilabulo, a traditional food of Gorontalo, Indonesia, through a qualitative ethnographic approach involving observation, documentation, and informal interviews with two local participants. The findings reveal two main concepts: ratio and proportion in mixing ingredients and geometry in wrapping and shaping, both of which were mapped to relevant school mathematics topics and further developed into contextual word problems. In addition, the study suggests that the process of preparing Ilabulo can be adapted into a video-based learning resource to support the problem-orientation stage in Problem Based Learning (PBL). These results demonstrate that everyday cultural practices can serve as meaningful contexts for mathematics learning, making abstract concepts more engaging and relevant while also strengthening students’ cultural identity.

Abstract

The low level of students’ mathematical problem-solving ability remains a challenge in the learning process, particularly in statistics topics. One effective approach to address this issue is scaffolding, which provides temporary support that helps students understand problems and find solutions independently. However, in classroom settings, individualized scaffolding is often suboptimal due to the large number of students compared to the limited number of teachers and the relatively short instructional time. This study aims to develop a computer-based scaffolding interactive learning medium that is feasible and practical for enhancing students’ mathematical problem-solving ability. The research employed a Research and Development (RD) design using the ADDIE model, consisting of five stages: Analysis, Design, Development, Implementation, and Evaluation. The media were developed using Canva, Microsoft PowerPoint, and iSpring Suite, and published via GitHub Pages for online accessibility. The validation results showed a feasibility score of 91.11% from material experts and 93.33% from media experts, both categorized as excellent. The practicality tests conducted by teachers and students each obtained a score of 92%, indicating that the media are easy to use and effective in facilitating learning. Therefore, the interactive learning media “Stafolding” are considered feasible and practical to be used as a computer-based scaffolding tool in mathematics learning.

Abstract

Penelitian ini bertujuan untuk meningkatkan hasil belajar matematika siswa melalui model Problem Based Learning (PBL) pada materi sistem persamaan linear dua variabel. Penelitian tindakan kelas (PTK) ini dilakukan pada 19 siswa kelas VIII di MTs Al-Mabrur Bone Raya selama dua siklus, mengikuti tahapan perencanaan, pelaksanaan, observasi, dan refleksi. Data diperoleh melalui observasi guru dan siswa serta tes hasil belajar. Pada siklus I, observasi menunjukkan kriteria cukup baik, dengan ketuntasan hasil belajar 63,2%—12 dari 19 siswa mencapai nilai di atas kriteria ketuntasan minimal (KKM). Karena indikator keberhasilan belum tercapai, penelitian dilanjutkan ke siklus II dengan perbaikan pada pelaksanaan pembelajaran. Hasilnya, observasi terhadap guru dan siswa meningkat ke kriteria baik, dan ketuntasan hasil belajar mencapai 84,2%—16 dari 19 siswa berhasil mencapai atau melebihi KKM. Kesimpulan dari penelitian ini adalah bahwa penerapan model PBL dapat meningkatkan hasil belajar siswa pada materi sistem persamaan linear dua variabel.

Abstract

Penelitian ini merupakan peneltian tindakan kelas yang bertujuan untuk meningkatkan hasil belajar matematika siswa melalui model discovery learning berbantuan wordwall pada materi bentuk aljabar. Subjek penelitian adalah 20 siswa kelas VII MTs Al Mabrur Bone Raya. Penelitian dilaksanakan dalam dua siklus yang terdiri atas tahap perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Teknik pengumpulan data dilakukan melalui instrumen lembar observasi dan tes hasil belajar. Data dianalisis secara deskriptif kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa model discovery learning berbantuan wordwall dapat meningkatkan hasil belajar matematika siswa. Hasil data dari instrumen dianalisis secara keseluruhan dan menunjukkan terjadi peningkatan rata-rata persentase sesudah diterapkan tindakan lanjutan untuk perbaikan proses belajar mengajar pada siklus II. Dimana aspek observasi seluruh aktivitas guru dan aktiivitas siswa serta hasil belajar siswa diperoleh 80% sesuai dengan indikator keberhasilan penelitian. Pada ranah afektif dan psikomotorik setelah perbaikan pada siklus II mengalami peningkatan 80% sesuai dengan indikator keberhasilan penelitian. Untuk itu, dengan menggunakan model pembelajaran discovery learning berbantuan wordwall dalam pembelajaran matematika dapat meningkatkan hasil belajar matematika siswa pada materi bentuk aljabar.

Abstract

The purpose of this study was to improve students' mathematics learning outcomes on matrix material through the application of cooperative learning model type Numbered Head Together (NHT). The subjects of this study were 23 students of class XI IPA-2 SMA Negeri 7 Prasetya Gorontalo in the academic year 2022/2023. Data collection techniques consisted of observation and tests. The research instrument is in the form of teacher and student activity observation sheets and tests in the form of description questions. This research is a Classroom Action Research using the Kemmis and Mc Taggart model with planning, action implementation, observation, and reflection stages. Data analysis techniques in this study consisted of data analysis of observation results and analysis of learning outcomes tests. The results showed that in cycle 1, the average observation of teacher activities that obtained at least good criteria was 81.25%, the average observation of student activities that obtained at least active criteria was 71.43%, the percentage of completeness of students' math learning outcomes was 60.87%. Because cycle 1 has not yet reached the action success indicator, the research continued to cycle 2. In cycle 2, the percentage of teacher activity observation results that obtained at least good criteria was 100%, the percentage of student activity observation results that obtained at least active criteria was 92.86%, and the percentage of completeness of students' mathematics learning outcomes was 91.30%. From the results of cycle 2, it is concluded that the application of cooperative learning model type NHT can improve students' mathematics learning outcomes on matrix material.
