The Effectiveness of Software GeoGebra to Improve Visual Representation Ability

Abstract

Abstract GeoGebra is a mathematical software that supports learning mathematics to make it easier to visualize geometric shapes. Geography software can create geometric images that are 2 dimensional or 3 dimensional so that GeoGebra can help students to represent real geometric shapes. This research aims to view the effectiveness of GeoGebra software in improving students’ visual representation ability. This study used a one-group pre-test/post-test design pre-experiment. The sample in this ability were students of eight grades SMP Negeri Sukoharjo who studied the material of flat-sided building. The instruments used in this study were the pre-test with and post-test of mathematical representation abilities. The results showed that there was an effectiveness of using GeoGebra in improving students’ visual representation skills with the difference in the mean score of students after being given geoGebra treatment was 61.3 for the pre-test and 70.5 for the post-test.
