Analisis Penerapan Media Pembelajaran Geogebra dalam Mengembangkan Kemampuan Komunikasi Matematis Siswa Pokok Bahasan Sistem Persamaan Linier Dua Variabel

Abstract

Abstract: The objective of this research was to find out students’ learning activity on Linear Equation System of Two Variables subject using Geogebra learning media, to find out if there was an increase in the students’ mathematic communication skills on Linear Equation System of Two Variables subject using Geogebra learning media, and to describe the students’ mathematic communication skills on Linear Equation System of Two Variables subject using Geogebra learning media. This research was conducted at SMP Negeri 1 Ngusikan. Based on the data in the school, the students’ mathematic communication skills was still low, so the use of Geogebra media was expected to increase students’ mathematic communication skills. This research applying qualitative research. The data were collected by tests and interview. To analyzing the students’ mathematic communication skills, the researcher did pre-test and post- test. The result showed that the application of Geogebra learning media can increase the students’ mathematic communication skills on Linear Equation System of Two Variables subject. It proved from the students work process in accordance with the indicators of students’ mathematic communication. Furthermore, the students’ mathematic communication skills will be described by the factors which include the learning process, students’ attitudes and comprehension, also giving question that can measure mathematical communication skills continuously.
