PENINGKATAN KEMAMPUAN KOMUNIKASI MATEMATIS PESERTA DIDIK MELALUI OPEN ENDED PROBLEM

Abstract

Mathematical communication skills which include the ability to write, draw, and express mathematics are an important part of learning mathematics. Teachers need to design learning to develop mathematical communication skills. Open ended problems give students the opportunity to convey their ideas and concepts which is the initial part of developing mathematical communication skills. The purpose of this study was to test the improvement of mathematical communication skills through habituation of open-ended problems on the material wide plane shapes. This type of research is an experimental with quasi-experimental designs method. Data obtained through tests of mathematical communication skills before and after refraction open ended questions on the material wide flat area. Data analysis using paired t test and continued with normalized gain test. The results showed there was an increase in mathematical communication skills with =0,42 meaning an increase in mathematical communication skills in the medium category.
