Abstract

Penelitian ini dilatarbelakangi oleh rendahnya pemahaman siswa dalam konsep operasi hitung bilangan kecil. Tujuan penelitian ini adalah mendeskripsikan penerapan model Pembelajaran Matematika Realistik berbantuan Blok Dienes untuk meningkatkan hasil belajar siswa kelas IV SDN 1 Paring Lahung. Penelitian ini dilaksanakan selama dua siklus. Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK). Teknik pengumpulan data menggunakan observasi, tes, dan dokumentasi. Hasil penelitian menunjukkan bahwa pada siklus I jumlah siswa yang memperoleh nilai ketuntasan minimal 70 sebanyak 1 siswa (11,1%) dan yang tidak memenuhi nilai ketuntasan minimal 70 sebanyak 8 siswa (88,8%) dengan nilai rata-rata siswa sebesar 25, 8. Pada siklus 2 mengalami peningkatan yang signifikan, jumlah siswa yang memenuhi nilai ketuntasan minimal 70 sebanyak 10 siswa (90,9%) dan yang tidak memenuhi nilai ketuntasan minimal 70 sebanyak 1 siswa (9,1%) dengan nilai rata-rata siswa sebesar 84 ,8. Hasil belajar siswa mengalami peningkatan dari siklus I ke siklus II sebesar 79,8%. Dapat disimpulkan bantuan bahwa penerapan model Pembelajaran Matematika Realistik dengan Blok Dienes dapat meningkatkan hasil belajar siswa kelas IV SDN 1 Paring Lahung pada operasi hitung bilangan kecil.

Abstract

This study aims to describe the effectiveness of using Geogebra in improving students’ understanding of relations and functions as well as their learning activities, while also describing the implementation process and obstacles experienced by students during the learning. This learning was designed with a Deep Learning approach contained in Geogebra-based student worksheet (LKPD). This study uses a mixed-methods approach with a sequential explanatory design. The research subject consisted of 25 eight-grade students at Bethel Palangka Raya Junior High School. Quantitative data were collected through pretest, posttest, and questionnaires, while qualitative data were obtained through interviews and students’ work on the worksheets (LKPD). The result showed a significant increase in the N-Gain score of 0,47 (medium category). Statistical tests also showed significant difference in understanding before and after using Geogebra (sig. = 0.008). The results of the positive response were also obtained through questionnaires and interview with three students.

Abstract

This research is motivated by the low utilization of technology in mathematics learning. Although students are accustomed to using digital devices such as smartphones, the reality in the field still shows obstacles in optimally implementing technology. Therefore, innovative learning media are needed to utilize technology optimally and attract student learning interest, one of which is through e-learning platforms such as Desmos. This study aimed to determine the effectiveness of the application of Desmos learning media on students' mathematics learning outcomes in the quadratic function material of class X of SMA Negeri 5 Palangka Raya. This research was conducted in May 2025. The subjects of this study were 36 students of class X-2 of SMA Negeri 5 Palangka Raya in the even semester of the 2024/2025 academic year. This type of research uses applied research with qualitative and quantitative data analysis. Data collection techniques were carried out through observations of teacher and student activities, student response questionnaires, and written tests. The results of the study showed that the use of Desmos in learning quadratic functions positively impacted student learning outcomes. The average final test score reached 80.3%, with a classical completion rate of 80%, and student responses to Desmos were in the "good" category, with an average of 72.83%. Based on these results, Desmos has been proven to increase student active engagement and understanding of quadratic functions.
