Analysis of mathematical communication skills of class 8 students on two-variable linear equation systems (SPLDV) concept

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 skills, namely 1) The ability to make mathematical expressions, including the ability to state situations, images, diagrams, or real objects into language, symbols, ideas, or mathematical models, 2) Ability to state situations or mathematical 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 ability had low mathematical communication skills on each indicator.

Students’ Mathematical Communication Skills in Solving STEM Problems

“…Based on the x and y values obtained, students can determine how much chicken meat is needed for tiger and lion tails to get conclusions from the answers correctly based on mathematical problems related to aspects of science. This is relevant to the statement that students can write answers using their language and complete them thoroughly [20]. The strategy of solving a problem used is coherent and systematic [21].…”
