Implementation of Geogebra Application to Improve Students' Mathematical Concept Understanding Ability

Abstract

This study aims to evaluate the effectiveness of using the Geogebra application in improving the understanding of mathematical concepts. The research method used is Classroom Action Research (CAR) which is carried out in two cycles, involving 25 students. Which refers to the Taggart model, where each cycle consists of four stages, namely planning, implementation, observation and reflection.

The results showed that the use of Geogebra significantly improved students' understanding of mathematical concepts, as indicated by an increase in the average score from 79 in the first cycle to 87.6 in the second cycle. In addition, the percentage of students who achieved the minimum completion criteria (KKM) increased from 76% to 88%.

This study can conclude that the use of the Geogebra application can improve student learning outcomes in mathematics learning. seen in the learning process in each cycle, as well as satisfactory learning outcomes
