Analisis Kemampuan Komunikasi Matematis Peserta Didik SMP pada Pemecahan Masalah Matematika

Abstract

This research aims to assess the level of students' mathematical communication skills in mathematics subjects with statistics material when faced with mathematical problems.  The population of this study was 32 students consisting of 17 men and 15 women in Class IX A UPT SMPN 34 Gresik.  The subjects in this study were 9 students who were divided into three groups, namely high, medium and low, the group division was based on the mathematics assessment on the report card.  This type of research is descriptive qualitative, with the aim of describing students' abilities in communicating mathematical ideas when working in groups to solve mathematical problems.  The research tools used in this research include written test instruments and interviews designed to measure students' mathematical communication skills, a written test consisting of two questions, then students' answers are communicated using in-depth interviews.  The results of the research showed that in the written test, the high group subjects had quite good performance on question number 1, while the middle group and low group subjects had good performance in mathematical communication skills on question 1. On question number 2 the high group and low group subjects had  good performance in solving problems, while the medium group subjects were still not good in expressing their arguments regarding mathematical communication in solving mathematical problems.
