Abstract This study investigated GeoGebra software and students` performance in teaching and learning of circle geometry. The study was guided by two objectives, two research questions and two null hypotheses which were tested at .05 alpha level. The pretest-posttest quasi-experimental research design was employed for the study. The population and sample were all the 25,913 and 117 senior secondary school two students respectively from the 33 public schools in Yenagoa Local Government Area of Bayelsa State. The purposive sampling technique was employed to select the sample. The instrument used for the collection of data was Geometry Performance Test (GPT). A reliability index of .75 was established for GPT using the test-retest method. The mean, standard deviation and analysis of covariance was used to analyze the data. The result showed that students in the experimental group that were taught circle geometry using GeoGebra software performed higher than their counterparts in the control group that were taught using the traditional method. The result further showed that there was a significant difference between the mean performance of students taught circle geometry using GeoGebra and those taught using the traditional method. There was no significant difference between the mean performance of the male and female students taught circle geometry using the GeoGebra software. It was concluded that use of GeoGebra software to teach circle geometry improved students? performance than the traditional method. Keywords: GeoGebra, Performance, Circle Geometry, Software, Teaching.
