Abstract :
This study is entitled ?EFFECT OF USING GEOGEBRA IN LEARNING TO THE MATHEMATICS LEARNING ACHIEVEMENT BY THE STUDENTS OF SENIOR HIGH SCHOOL?This study aims to determine whether there is influence of the use of GeoGebra in learning to mathematics learning achievement of Senior High School students. Samples in the research are Senior high school students of class XI IPA 2 which amounted to 42 people.The data used in the research is pretest and posttest data from experimental class taught by using GeoGebra. The data obtained were analyzed using SSPS program version 20.0. Before hypothesis test, it was done a prerequisite test such as normalits test for pretest data and postest data. From the results of data analysis for pretest, it is gotten the value of Asymp.Sig (2-tailed) = 0,086> 0,05 and Dcount = 0,132 <0,220 = Dtable so, H0 is accepted, thus it is concluded that the data is normally distributed. While in posttest data, the value of Asymp.Sig. (2-tailed) = 0,066> 0,05 and Dcount 0,136<0,220 = Dtable then H0 is accepted, thus it is concluded that the data is normally distributed. Hypothesis test using Paired Sample Test, after the data were analyzed obtained value of Sig. (2-tailed) = 0,000 <0,05 and tcount = -87,520 <-2,024 = -ttable, so reject H0, so concluded there is influence of using GeoGebra in learning to the learning achievement of senior high school students.The results of this study show the use of GeoGebra in learning mathematics influence on mathematics learning achievement. Based on the results of this study, the authors suggest for teachers to be able to make the GeoGebra media as an alternative to use in the process of learning mathematics by adjusting the material being taught.
