Abstract

This study aims to determine the effect of using GeoGebra as a learning medium on students’ mathematics learning outcomes in the Pythagorean theorem material among eighth-grade students of SMP Negeri 23 Mataram in the 2025/2026 academic year. This research employed a quasi-experimental method with a posttest-only control group design. The population in this study consisted of all eighth-grade students of SMP Negeri 23 Mataram in the 2025/2026 academic year. The sample was determined using a saturated sampling technique, in which the entire population consisting of two classes was taken directly as the sample. Class VIII B was assigned as the experimental group and class VIII A as the control group. The experimental group used GeoGebra as the learning medium, while the control group used PowerPoint. The research instruments included observation sheets, learning outcome tests, and learning tools. Data analysis using the t-test showed that the calculated value = 2,194 was greater than = 1,999. This means that there was a difference in the average mathematics learning outcomes between students in the experimental class who used GeoGebra and students in the control class who used PowerPoint. The average post-test score of the experimental class was 74,19, which was higher than the control class score of 63,13, with the effect categorized as moderate based on the effect size value of = 0.558. Thus, it can be concluded that there is an effect of using GeoGebra as a learning medium on the mathematics learning outcomes of eighth-grade students of SMP Negeri 23 Mataram in the Pythagorean theorem material for the 2025/2026 academic year.

Abstract

Penelitian ini bertujuan untuk mengetahui hubungan motivasi belajar dan perhatian orang tua terhadap hasil belajar siswa pada materi bentuk aljabar kelas VII SMP Negeri 4 Lingsar tahun ajaran 2025/2026. Jenis penelitian ini ex-post facto. Adapun sampel yang digunakan dalam penelitian ini sebanyak 64 orang siswa terdiri dari 2 kelas yang dipilih dengan teknik cluster random sampling. Instrumen dalam penelitian ini menggunakan angket motivasi belajar, angket perhatian orang tua dan tes hasil belajar siswa. Analisis data dilakukan melalui analisis deskriptif dan inferensial, meliputi uji prasyarat dan uji korelasi product moment, berganda dan analisis koefisien determinasi. Hasil penelitian menunjukkan bahwa motivasi belajar memiliki hubungan positif dan signifikan dengan hasil belajar siswa dengan koefisien korelasi r= 744 yang berada pada kategori kuat. Nilai R2 = 0,544 menunjukkan bahwa motivasi belajar memberikan kontribusi sebesar 55,4% terhadap hasil belajar. Perhatian orang tua juga memiliki hubungan positif dan signifikan dengan hasil belajar siswa dengan koefisien korelasi r = 0,568 dengan kategori kuat. Nilai R2 = 0,433 yang berarti perhatian orang tua memebrikan kontribusi sebesar 43,3% terhadap hasil belajar. Secara simultan, motivasi belajar dan perhatian orang tua memiliki hubungan positif dan signifikan dengan hasil belajar siswa dengan koefisien korelasi berganda r = 0,767 yang termasuk kategori kuat dengan nilai R2 =0,588 menunjukkan bahwa kedua variabel secara bersama-sama memberikan kontribusi sebesar 58,8% terhadap hasil belajar siswa.
