Analysis of Students' Mathematical Communication Ability on Two Variable Linear Equation Systems (SPLDV) Materials

Abstract

This study aims to determine and analyze aspects of students' mathematical communication skills in the material of two-variable linear equations (SPLDV. The study was conducted with a sample of 5 students from 30 populations with different abilities and were taken randomly at one junior high school in Jakarta. used is descriptive qualitative. The research instrument is a test of mathematical communication skills in the form of 5 essay questions and interviews. The results of the tests that have been carried out show the results of communication skills in the medium category because there are 3 questions whose percentage is in the medium category and 2 other questions in the low category It can be seen from the percentage of scores per item, that is question no. 1 has a percentage of 60%. Question no.2 has a percentage of 45%. Question no.3 has a percentage of 40%. Question no.4 has a percentage of 30%. And questions no.5 with the acquisition of a percentage of 25%. Thus, it can be concluded that the ability to communicate The mathematical students on the material of a system of linear equations of two variables are included in the medium category.
