Analisis Kesulitan Siswa Pada Materi Sistem Persamaan Linear Dua Variable di Kelas VIII SMPN 8 Banda Aceh

Abstract

Solving the problem of a two-variable linear equation system is the process of determining the solution to a two-variable linear equation system. However, in reality, many junior high school students have difficulty solving the problem of a two-variable system of linear equations. It is important to study student difficulties to get an idea of what obstacles students experience when studying or solving mathematical problems. This study uses a descriptive qualitative approach. The subjects of this study were students of class VIII.5 State Junior High School 8 Banda Aceh totaling 26 students. This research instrument uses a mathematical problem solving test instrument and interview guidelines. Data analysis is done by reducing, presenting, and concluding. The results of the analysis showed that 38% had difficulty understanding the concept, 20% had difficulty applying the method, and 29% had verbal difficulties in solving SPLDV using the substitution method, the elimination method, the mixed method, and the graphic method. The implications of the research results can be used as a reference for teachers in knowing the difficulties experienced by students in solving SPLDV problems.
