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

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