Analysis of Students' Mathematical Communication Skills in Solving Mathematics Questions for Number Patterns

Abstract

This study aims to analyze students' mathematical communication abilities in solving math questions with number patterns. The type of research is descriptive qualitative research. The research participants were is consisting of 6 students of grade VIII C students of SMP Negeri 3 Sungguminasa in 2019/2020 with high, moderate, and low abilities. The collection technique in this study was in the form of written tests and interviews. The instrument used is a description test which contains indicators of mathematical communication abilities in number pattern material, a totally of 5 questions. The results of this study indicate that students' mathematical communication abilities were in the moderate categories. Students with high abilities are already in the good categories, marked by the achievement of all indicators of mathematical communication abilities. Students with moderate abilities are still in the moderate categories, marked by students only being able to achieve the ability to explain mathematical ideas with pictures and express everyday events in mathematical language. Meanwhile, low-ability students are still in the low categories, marked by students only being able to fulfill their ability to compile arguments and formulate generalizations using their own language.
