Abstract:
Orthographic projection represents three-dimensional objects in two dimensions from multiple views—front, top, and side—using parallel lines that are perpendicular to the drawing plane. This method maintains accurate geometry and scale, eliminating distortion caused by perspective. This study investigates the orthographic projection skills of Drafting Technology students through an assessment based on Speed, Legibility, Accuracy, and Neatness (SLAN). The research aimed to determine skill levels across various factors such as academic performance, access to gadgets, financial status, senior high school track, and sex. Quantitative data were gathered and analyzed using statistical tools including frequency, percentage, mean, standard deviation, t-test for Independent Samples, and One-way ANOVA. Results indicated significant differences in performance, notably among students with varying academic backgrounds and levels of access to technology. Students who had better access to gadgets and stronger academic preparation generally performed better in SLAN-based tasks. The study highlights the importance of integrating support mechanisms and differentiated instruction into the curriculum to bridge skill gaps. The findings can guide educators and administrators in developing targeted interventions that enhance technical drawing skills, improve equity in learning outcomes, and better prepare students for professional practice in drafting and related fields.
