Pemanfaatan Media Geogebra untuk Meningkatkan Pemahaman Konsep Matematika Materi Bangun Datar

Abstract

This study aims to determine the use of GeoGebra media in improving the understanding of mathematical concepts in the material of flat shapes of fifth grade students of SDN Tanjungrejo 4 Malang City. The method used is Classroom Action Research (CAR) model Kemmis and McTaggart with stages of planning, action, observation, and reflection. Data were collected through documentation, observation, and tests using descriptive choice instruments. Data analysis was carried out quantitatively with descriptive statistics. The results showed an increase in the applicability of the media, the average understanding of the concept from 58% (pre-action) to 65% in cycle I and 84% in cycle II. Each indicator of conceptual understanding also increased, such as restating the concept in cycle 1 an average of 62 in cycle 2 increased to 85, classifying objects an average of cycle 1 64 in cycle 2 increased to 85, identifying examples and non-examples an average of cycle 1 66% in cycle 2 increased to 81% and applying concepts in problem solving an average of cycle 1 70% in cycle 2 increased to 85%. This study concludes that GeoGebra media is effective in improving understanding of mathematical concepts. Active student engagement, reflection, and collaborative discussion are crucial factors in successful learning.
