Effectiveness of geometrical instructional teaching strategy on junior secondary school students’ Achievement, Gender and Attitude in Plane Geometry in Odeda Local Government, Ogun state, Nigeria

This research study was concerned with the effectiveness of Geometrical Instructional teaching strategy on Junior Secondary School Students’ achievement, gender and attitude in Plane geometry in Odeda Local Government, Ogun State, Nigeria. The research study compared the effect of using Geometrical Instructional Teaching Strategy(GITS) and the conventional teaching approach on the achievement, gender and attitude of Junior Secondary School Students in Plane Geometry. The research was a pre-test post-test quasi-experimental control group design. Four (4) Junior secondary schools were purposefully chosen because of the availability of computers in these schools. Stratified random sampling technique was used to select the sample of 240 students (120 males and 120 females) drawn from four schools within the local Government. Four intact classes were used by the researchers for both experimental and the control groups. The experimental group was taught using Geometrical Instructional Teaching strategy package while the control group was taught using conventional teaching approach method. The Geometry Achievement test (GAT) consisting of (15) multiple choice items with four options, and Attitude Inventory on Plane Geometry (IIPG) were administered to students as pre-test and post-test before and after the treatment. Data collected was analyzed using descriptive statistics of mean and standard deviation to answer the four (4) research questions while the hypotheses were tested using analysis of covariance(ANCOVA). Result of the study revealed that students taught plane geometry using Geometrical Instructional Teaching Strategy package achieved higher mean scores than those students taught using conventional method. The result also revealed non-significant difference in the mean achievement and the mean attitude scores of males and female’s students taught plane geometry using Geometrical Instructional package and those students taught using conventional method. Some recommendations were made among which are that mathematics teachers should include the use of Geometrical Instructional Teaching Strategy to teach plane geometry.
