Abstract
Spatial visualization ability is essential to the success in technical drafting students. However, as observed during classes and as reported from previous studies, students exhibit difficulty with the basic concepts of technical drawings and spatial visualization ability. To address this gap in the literature, this study aims to examine the effect of a 3D solid object as an instructional aid strategy to improve the spatial visualization ability among 30 Technology and Drafting students in a community college in Misamis Oriental, Philippines. This study employed an explanatory mixed method where a one-group pretest-posttest design was utilized to collect quantitative data. Personal interviews were subsequently conducted to gather data that will explain the numerical results. The research instruments were adopted from the Mental Rotations Test (MRT), Purdue Spatial Visualization Test: Visualization of Rotations, and Differential Aptitude Test: Space Relations (DAT:SR). Findings of this study revealed that the 3D solid object has significantly improved the students' visual spatialization ability as the sight, depths perception, and tactile senses are activated during their classes. Recommendations for curricular planning and future studies are discussed in this paper.
