Abstract

This research aims to describe the mathematical communication skills of class VIII students, as well as the mistakes made by students in solving answers to the two-variable linear equation system problem. This research was conducted with a qualitative descriptive method. The subjects in this study were 3 eighth grade students of SMP Negeri 1 Dendang. Which consists of one student with high mathematical ability, one student with moderate ability, and one student with low ability. To find out how far mathematical communication skills are measured based on indicators of mathematical communication capabilities, namely 1) The ability to make mathematical expressions, including the ability to state situations, pictures, diagrams, or real objects into language, symbols, ideas, or mathematical models 2) the ability to state mathematical situations or ideas in the form of images, diagrams, or graphs, 3) The ability to write answers in their own language. The results showed that high-ability students had mathematical communication skills of students quite well on each indicator, medium-ability students also had good mathematical communication skills on indicator 1, student 3 with low abilities had low mathematical communication abilities on each indicator.
