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.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi faktor apa saja yang menyebabkan rendahnya hasil belajar peserta didik. Penelitian ini dilakukan di SMK Negeri 1 Tonjong karena nilai rata-rata ujian nasional mata pelajaran matematika di sekolah tersebut setiap tahunnya paling rendah dibanding mata pelajaran yang lain. Metode penelitian ini menggunakan metode deskriptif kualitatif dengan teknik pengumpulan data observasi melalui angket dan wawancara. Hasil penelitian ini menunjukan bahwa rendahnya hasil belajar ternyata dipengaruhi oleh beberapa faktor, yaitu faktor internal yang mencakup peserta didik tidak tertarik dengan matematika, kemampuan dasar berhitung siswa lemah, rendahnya pemahaman konsep peserta didik, peserta didik tidak mengerti lambang-lambang dalam matematika, kurangnya kedisiplinan peserta didik, dan kurangnya motivasi belajar peserta didik. Faktor eksternal mencakup ruang kelas yang panas sehingga membuat tidak nyaman, ruang kelas teori yang bising karena dekat dengan ruang praktik sehingga fokus peserta didik tidak optimal, dan faktor dari guru, yaitu kurang menarik peserta didik dalam menyampaikan materi sehingga peserta didik merasa bosan dan tidak berani bertanya.
