GEOBAORD APPLICATION ON GEOMETRY TEACHING AND SENIOR SECONDARY SCHOOL STUDENTS’ ACADEMIC PERFORMANCE IN DEGEMA LOCAL GOVERNMENT AREA, RIVERS STATE
This study advocated the efficacy of Geoboard manipulative in senior secondary school students’ academic performance in the teaching and learning of Geometry. A sample of one hundred (100) Senior Secondary School One (SSS1) students were used by Simple Random Sampling Technique from two secondary schools in Degema Local Government Area of Rivers State. The instrument for data collection was pretestposttest Geometric Performance Test (GPT). The reliability of the instrument was tested outside the sample with the coefficient of 0.98 using Pearson’s Product Moment Correlation (PPMC) method.The instrument was validated by two Mathematics experts. This research was guided by two (2) objectives, two (2) research questions and two (2) hypotheses. The research questions were answered using mean and standard deviation, while analysis of co-variance (ANCOVA) was used to test the hypotheses at 0.05 level of significance. Findings established that Geoboard technique revealed effectiveness of Geoboard in providing adequate structure for in-depth learning of authentic tasks leading to meaningful understanding and hence enhance better performance of Geometry which was perceived as difficult by senior secondary school students. It also demonstrated that Geoboard is a very effective technique in enhancing students’ performance in Geometry. KEYWORDS: Geoboard, Manipulative, Teaching-Learning.
