Analisis Kesalahan Siswa dalam Menyelesaikan Soal Cerita SPLDV Berdasarkan Tahapan Newman

Abstract

This study aims to observe the errors of class IX junior high school students in solving the problem of a two-variable system of linear equations in the form of a narrative math problem. The research subjects were 24 students of class IX. This research instrument uses 3 narrative mathematical problems of a two-variable linear equation system according to the Newman error analysis indicator. A qualitative descriptive approach was used in this study. The results obtained, some students have difficulty on indicators to solve problems involving a system of linear equations of two variables. Based on Newman's error analysis, the causes of student errors in solving two-variable linear equation system narrative math problems are: (1) 35% for reading errors in the very low category are caused by difficulties in interpreting the meaning of words or terms in the problem; (2) 61% for comprehension errors in the low category due to students not writing down the known and asked elements; (3) 50% for transformation errors in the very low category is due to difficulties in determining procedures and formulas; (4) 59% for process skill errors in the low category caused by errors in the calculation process; and (5) 58% for encoding errors in the low category were caused by students not writing conclusions.
