Effects Of Geogebra And Desmos Software On Students’ Performance In Coordinate Geometry In Warri South, Delta State, Nigeria.

Abstract

 This study examined the effects of Geogebra and Desmos software on senior secondary schools 3 (SS 3)  students' performance in Coordinate Geometry in the Warri South Local Government Area of Delta State, Nigeria. The research explored how the integration of dynamic Mathematics software – Geogebra and Desmos – impacts learning outcomes compared to traditional teaching methods.  This study used a pretest-posttest control group structure in a quasi-experimental approach. Purposive sampling was used to conveniently choose 118 SS 3 kids from three schools out of the 2,350 students that made up the study's population. Two groups of participants were formed: the experimental group received education using Desmos and GeoGebra, while the control group was instructed using the traditional lecture method. The Coordinate Geometry Performance Test (CGPT) was used as the data gathering tool. The Kuder–Richardson Formula 21 (KR-21) method for CGPT yielded a reliability index of 0.89. The two research questions were addressed using mean and standard deviation, and the two hypotheses developed for the study were tested using Analysis of Co-variance (ANCOVA) at the 0.05 level of significance. Data were collected through pre- and post-test assessments and class observations. Findings reveal that students instructed with Geogebra and Desmos demonstrated significant improvement in conceptual understanding, problem solving skills and overall performance in coordinate geometry compared to their peers in the control group. Additionally, learners exhibited increased motivation, better visualization of geometric concepts. The results indicate that the use of interactive software can effectively enhance mathematical instruction and support learners in mastering coordinate geometry. The study concludes with recommendations for integrating technology – based tools into the Mathematics curriculum to improve academic achievement and foster positive attitudes towards learning Mathematics in Warri South and similar educational contexts.
