Abstract

This research is a case study of qualitative research that purposed for describing the ability of mathematical reasoning in solving System of Two Variable Linear Equation (SPLDV) Chatolic Junior High School of ST. Yoseph Naikoten Kupang. The subjects of this research were theree students of class VIIIA who were chosen after being given a written test. The test was given to the students of class VIIIA after obtaining the material System of Two Variable Linear Equation (SPLDV). The data collection was the test result of data, interview result and documentation. Data analysis includes data reduction, data presentation and conclusion drawing. Checking the validility of the data using triangulation of time. After the data is presented and analyzed it can be concluded that the high ability subject tend to be able to reach six indicators, such as: submiting allegations; carrying out mathematical manipulations; drawing conclusions; compiling evidence; giving reasons or evidence to the correctness of the solution; drawing conclusions from statements; checking authenticity arguments, determine the pattern or nature of mathematical symptoms to make a generalization. Research subjects with moderate abilities tend to be able to reach two indicators such as: submiting allegations; carrying out mathematical manipulations. Lowability subjects didn’t able to achieve the indicator of mathematical reasoning ability
