Academic Performance in Geometry and Visualization Skills of Pre-Service Teachers

This descriptive-correlational study aimed to enhance the visual imagery and spatial visualization skills in Geometry of pre-service ‎Mathematics teachers, with the end goal of preparing a learning enhancement material. It described the academic performances and ‎visualization skills of 147 pre-service Mathematics teachers, who have taken up Plane and Solid Geometry, stratified from selected ‎colleges and universities in Batangas. The relationship between the levels of their visualization skills and their academic ‎performances in Plane and Solid Geometry was found out. The difficulties encountered by the respondents in solving problems in ‎Geometry, relative to their visualization skills, were also assessed. Results from the findings revealed that the average pre-service ‎Mathematics teacher possessed good academic performance in Plane and Solid Geometry, medium levels of visual imagery and low ‎levels of spatial visualization. The academic performances of pre-service Mathematics teachers in Geometry significantly correlated ‎with their visualization skills. Lastly, most of the pre-service Mathematics teachers often encountered difficulties in solving ‎problems in Geometry relative to their visualization skills. The Visual Enhancers Toolkit was prepared for pre-service Mathematics ‎teachers as a learning enhancement material in Geometry to further develop their visualization skills‎.
