AbstrakKesulitan siswa dalam memahami materi dimensi tiga perlu diatasi. Misalnya dengan menggunakan bantuan media pembelajaran yang tepat seperti Software GeoGebra. Penelitian bertujuan mendeskripsikan proses pembelajaran dan hasil belajar matematika menggunakan software GeoGebra. Penelitian deskriptif kualitatif ini terdiri dari 19 subjek kelas XII IPS salah satu MA swasta di Jombang. Instrumen penelitian yaitu lembar observasi, tes dan dokumentasi. Berdasarkan hasil penelitian diketahui bahwa proses pembelajaran dengan media software GeoGebra diawali dengan menyampaikan tujuan pembelajaran dan mengingatkan materi sebelumnya, menjelaskan unsur-unsur bangun ruang, memperkenalkan software GeoGebra, menjelaskan fungsi masing-masing menu, menjelaskan materi dimensi tiga menggunakan software GeoGebra, dan memberikan penguatan serta menyimpulkan inti materi yang telah dipelajari. Hasil penelitian lainnya menunjukkan bahwa terdapat perbedaan hasil belajar siswa yang signifikan antara sebelum dan sesudah pemanfaatan GeoGebra. Software GeoGebra cocok digunakan untuk membantu siswa memahami materi dimensi tiga dengan baik. Learning Mathematics with GeoGebra Software Media with Three-Dimensional MaterialAbstractStudents' difficulties in understanding three-dimensional material need to be overcome. For example, by using the help of appropriate learning media such as GeoGebra Software. The purpose of this research was to describe the learning process and learning outcomes of mathematics using GeoGebra software. This qualitative descriptive study consisted of 19 subjects of class XII IPS, one of the private MA in Jombang. The research instruments are observation sheets, tests, and documentation. Based on the results of the study, it is known that the learning process using the GeoGebra software media begins with conveying the learning objectives and reminding the previous material, explaining the elements of spatial structure, introducing the GeoGebra software, explaining the function of each menu, explaining the Three Dimensional material using the GeoGebra software, and closing with providing reinforcement and conclude the core material that has been studied. The results of other studies indicate that there are significant differences in student learning outcomes between before and after the use of GeoGebra. GeoGebra software is suitable to help students understand three-dimensional material well.
