An analysis of problem solving ability in linear equation systems with two variables

Abstract

Problem-solving is one of the mathematical abilities that students must possess. This study aims to analyze and describe students' problem-solving abilities in the linear equation systems with two variables as consideration for improving the quality of learning. This type of research is descriptive qualitative. The subjects of this study were 20 tenth grade students of SMA Negeri 1 Comal. They were taken by using purposive sampling method. This research variable is an indicator of problem-solving ability that consists of understanding the problem, identifying and planning problem-solving, solving problems according to plan, and re-examining the answers generated. The data were collected by using tests and interview methods. The result showed that 73,5% of the students were successful in understanding the problems, 59,5% of the students were successful in identifying and planning problem-solving, 38% of the students were successful in solving problems according to plan, and 26% of the students were successful in re-examining the answers generated. Most students were not able to model mathematical forms correctly and have difficulty in solving problems.
