Enhancing Spatial Visualization Skills in Engineering Drawing CourseAbstractStrong spatial visualization skills are important to an engineer’s ability to create and interprettechnical drawings, which is critical in thinking, modeling, and problem solving processes. Theability to visualize in three dimensions is a cognitive skill that is linked to success in engineering.Spatial visualization skill and its correlation with students’ success have received much attentionin technical education. The ability to understand important topics in engineering drawing such asorthographic projection, isometric drawing, hidden views, and sectional views is very critical asit represents the fundamentals of engineering drawing education. However, research shows thatsome learners with poor spatial ability had trouble understanding basic fundamental concepts ofengineering drawing. This study investigates the correlation between spatial visualization abilityand academic success in a Technical Drawing course which has three sections (i) hand drafting,(ii) 2D CAD drawing, and (iii) 3D CAD drawing. Students were pre- and post-tested using astandard mental rotation test to gauge spatial visualization ability and results are discussed forthree sections of this course.
