Abstract
GeoGebra provides many facilities that can help teachers in geometry animation and manipulation so that it can be used as a means of visualization and construction in finding mathematical concepts. Utilization of the GeoGebra program can provide students with a visual experience in exploring graphs of quadratic functions in mathematics learning. The use of GeoGebra software is not easy, for that we need assistance and guidance activities from experts that are packaged in the form of community service activities. Mentoring activities are carried out online for students of SMA Negeri 1 Pegandon, Kendal, Central Java, through the Zoom Meeting application. The first session is an introduction to GeoGebra and the slider tool in the GeoGebra application. The second session is an exploration of the graph characteristics of a quadratic function by manipulating GeoGebra. The results of the self-regulated learning response questionnaire show that 75% of students have the initiative to learn, 71.55% of students can diagnose learning needs, 75.86% of students can set learning targets, 71,55% of students view difficulties as challenges, 69.83% of students utilize relevant reference sources, 73.71% of students can set learning strategies, 74.14% of students can evaluate learning processes and outcomes, and 78.02% of students have the good self-concept. Through GeoGebra mentoring service activities, students can be motivated to solve quadratic function graph problems and increase learning independence.
GeoGebra banyak memberikan fasilitas yang dapat membantu guru dalam animasi geometri dan manipulasi sehingga dapat dijadikan sebagai sarana visualisasi dan mengkonstruksi dalam menemukan konsep matematis. Pemanfaatan program GeoGebra dapat memberikan pengalaman kepada siswa dalam mengeksplorasi grafik fungsi kuadrat pada pembelajaran matematika. Penggunaan software GeoGebra yang tidak mudah sehingga membutuhkan kegiatan pendampingan dan bimbingan dari ahli. Kegiatan pendampingan dilakukan secara online terhadap siswa SMA Negeri 1 Pegandon kabupaten Kendal Jawa Tengah melalui aplikasi zoom meeting. Sesi pertama kegiatan pengabdian adalah pengenalan GeoGebra dan tool slider pada aplikasi GeoGebra dan pada sesi kedua berupa eksplorasi karakteristik grafik fungsi kuadrat dengan memanipulasi GeoGebra. Hasil angket kemandirian belajar menunjukkan bahwa 75% siswa mempunyai inisiatif belajar, 71,55% siswa dapat mendiagnosa kebutuhan belajar, 75,86% siswa dapat menetapkan target belajar, 71,55% siswa beranggapan kesulitan bagian dari tantangan, 69,83% siswa memilih sumber referensi, 73,71% siswa dapat menetapkan strategi belajar, 74,14% siswa dapat melakukan evaluasi hasil belajar, dan 78,02% siswa memiliki self-concept yang baik. Melalui program pengabdian pendampingan geogebra dapat menjadikan siswa termotivasi untuk menyelesaikan masalah grafik fungsi kuadrat dan meningkatkan kemandirian belajar
