Implementation of Space Geometry Learning Using Geogebra to Improve Problem Solving Skills

Abstract

Prospective mathematics teachers must be equipped with problem solving skills because it has a very important place in the mathematics curriculum. The purpose of this research is to get an overview of improving the problem solving skills of prospective mathematics teachers by implementing GeoGebra on space geometry learning. The research was conducted in Study Program of Mathematics Education, Tidar University in the second semester students. This research uses quasi-experimental method, with nonequivalent control group pretest-posttest design using two groups, namely experimental group consisting of 36 students got GeoGebra-based space geometry learning and control group consisting of 35 students got conventional space geometry learning. Research instruments in the form of observation sheets and test instruments in the form of pretest and posttest to measure achievements of problem solving skills improvement. The data obtained is then processed and analyzed by calculating the percentage of learning implementation and calculating the average normalized gain score (N-Gain). The results showed that GeoGebra-based Space Geometry learning can improve problem solving skills. In the experimental group, problem solving skills were improved in high category, while in the control group the improvement of problem solving skills in moderate category.

Korelasi Pemahaman Mata Kuliah Logika Matematika Dengan Software Geogebra

“…Sejumlah guru memanfaatkan aplikasi GeoGebra untuk mengatasi permasalahan yang dihadapi dalam mengajarkan materi fungsi dan kalkulus. Pemanfaatan aplikasi GeoGebra dapat menguatkan konsep-konsep dasar fungsi kalkulus sehingga mahasiswa dapat mengeksplorasi dan mengembangkan pembelajaran yang telah dipelajarin di kelas (Toheri et al, 2017), peserta didik dituntun lebih aktif untuk mengembangkan konsep materi segitiga dengan menerapkan proses pembelajaran discovery learning sehingga peserta didiik lebih memahami materi untuk dapat menghubungkan antara ide matematika dengan abstrak yang konkrit (Suryani & Kamariah, n.d.), pembelajaran GeoGebra pada materi geometri dapat meningkatkan keterampilan pemecahan masalah berdasarkan hasil penilaian pretest dan posttest yang dikerjakan, dimana setiap grup diberikan 2 tindakan yaitu eksperimen dan kontrol pada saat menggunakan aplikasi geogebara maupun tanpa bantuan aplikasi (Pamungkas & Nugroho, 2020), pemanfaatan aplikasi GeoGebra dengan menerapkan teori belajar Van Hiele juga dapat membantu meningkatkan kemampuan penalaran matematis kelas eksperimen lebih tinggi daripada kelas kontrol (Budiman & Rosmiati, 2020).…”
