Analisis Kesalahan Siswa dalam Menyelesaikan Masalah Kontekstual Materi Sistem Persamaan Linear Tiga Variabel SMK Negeri 1 Bireuen

Abstract

Errors in solving problems related to Three-Variable Linear Equation Systems (TVLES) frequently occur during the learning process, especially in contextual problems. This study aims to analyze the errors made by students in solving contextual problems of TVLES in Grade XI at SMK Negeri 1 Bireuen. A qualitative descriptive method was used in this research. The subjects were Grade XI students at SMK Negeri 1 Bireuen, selected through a purposive sampling technique. Data collection techniques included an initial understanding test, problem-solving ability test, interviews, and documentation. The results of the analysis on the initial understanding test revealed that 6 students were classified as high-performing, 13 as medium-performing, and 2 as low-performing. In the proble-solving ability test, 2 students were in the high-performing group, 17 in the medium-performing group, and 2 in the low-performing group. Based on interviews, it was found that students made more factual and procedural errors. It can be concluded that students' understanding of TVLES material is relatively low.
