Effectiveness of Geogebra in Teaching Geometry

Abstract

The purpose of this study was to investigate effectiveness of GeoGebra in teaching geometry at grade IX. The effectiveness was measured by comparing achievement of the students taught by using GeoGebra and without using GeoGebra software and explain the student's perception in teaching geometry by using GeoGebra software. It is a quantitative research including experimental research design. The researcher selected two government schools; One for experimental groups and another for control group. There were 27 students for experimental group and 29 students were for control groups. Two groups were taught the same topic of geometry during one month. The researcher used pre-test and post-test non-equivalent experimental design. The experimental group was taught by using GeoGebra software and control group was taught by using traditional method. Mathematics achievement test was conducted on both groups to collect data for this research. A set of questionnaire based on five point Likart scale was used to experimental group to measure the perception towards GeoGebra software. The collected data were analyzed by comparing mean, S.D and t-test with the help of SPSS software. The result of this study shows that achievement of the students in experimental group has better than that of control group. Also from the result of questionnaire shows that positive perception towards GeoGebra software in teaching geometry. It is concluded that GeoGebra software is useful tool in teaching mathematics at secondary level.
