System of Linear Equation Problem Solving: Descriptive-Study about Students' Mathematical Connection Ability

Abstract

Algebra is one of the fields in mathematics studied by secondary school students. The students' ability to solve algebra problems is still low. This is due to their lack of ability to solve real-world problems. This is because their mathematical connection capabilities are also not good. Mathematical connection ability is one of the standard processes in learning mathematics. The purpose of this study was to describe the mathematical connection ability of secondary school students in solving algebra problems. This research method is descriptive-qualitative. The research subjects were each high, medium, and low ability secondary school student. The data obtained is the result of subjects' work in solving systems of three-variable linear equations. Subjects' work outcomes will be analyzed based on indicators of mathematical connection ability. The results of this study are high, medium, and low ability students able to meet several indicators in recognizing and using some ideas or concepts in mathematics. Students can understand how the concepts of mathematics are interconnected. Only highly capable student shows indicators of the application of mathematics in daily life problem.
