Abstract

Fragmentation of students’ thinking structure is a student’s thinking error. In this study, we want to know how students think in solving problems in everyday applications. This study aims to describe the fragmentation of the thinking structure of high school students in solving problems of a two-variable linear equation system. In line with the research objectives, the research uses qualitative discrete research methods. The research subjects were 2 students. Methods of data collection using tests and interviews. The technique of checking the validity of the data uses. Data triangulation and previous researchers references analysis techniques through data reduction steps, data presentation and conclusion drawing. Based on the results of the study, it was found that the subject’s errors in solving problems included the construction of the concept of missing information and partial insight. The focus in this study is students who experience concept construction in understanding the concept of a Two-variable Linear Equation System in story questions from the application in everyday life. Most students can only write examples correctly and cannot understand how to formulate story questions into mathematical models, because most of the Two Variable Linear Feeling System questions are directly in the form of mathematical models and only need to look for variables x and y, so students do not understand how to apply the problem story into mathematical model.
