Abstract The study examines the application of GeoGebra Software and students? performance in plane geometry in all the five mission secondary schools in Oshimili-South Local Government Area of Delta State. GeoGebra is an interactive geometry, algebra, statistics, and calculus application, intended for teaching and learning mathematics from primary school to university level. It can be used for active and problem oriented teaching that fosters mathematical experiments and discoveries both in the classroom and at home. The study was guided by three specific objectives, three research questions and three null hypotheses. The study is quasi-experimental, using a pre-test / posttest control design. Two schools were selected using purposive sampling and fifty-nine (59) secondary school II (SS2) mathematics students were drawn from the population of three hundred and twenty-four (324) students using intact classes. The classes were divided into two groups experimental and control which consist of 28 students for experimental group and 31 students for control group. The experimental group was taught using GeoGebra while the control group was taught using the conventional method and taught the same topics. The instrument used for the study was a Performance Mathematics Ability Test (PMAT). The reliability coefficient of the instrument was ascertained using Kuder-Richardson (20) and was found to be 0.75. The findings showed that there is a difference in the mean performance scores of secondary school students II who use GeoGebra in learning geometry (M=44.59, SD=4.95) and conventional method (M= 35.9, S.D = 7.169). It was recommended that mathematics teachers should appreciate GeoGebra software and use it in their teaching. Keywords: GeoGebra application; Gender; ability level.
