Technical drawing in SS2 (Senior Secondary School 2) is a specialised subject that teaches students the skills and knowledge to create precise and detailed drawings of objects and structures. It is essential for students aiming for careers in engineering, architecture, and other technical fields.
In SS2, the Lagos State unified scheme of work for technical drawing builds on what students learned in SS1. The scheme follows a step-by-step approach, starting with basic ideas and moving to more complex topics. It covers various subjects, including geometric constructions, orthographic projections, sectional views, and assembly drawings. Each topic helps students understand spatial relationships and visualize objects in three dimensions.
By studying technical drawing at this level, SS2 students become skilled in using drawing tools and software. The course emphasizes both manual drawing techniques and computer-aided design (CAD) tools, keeping up with the field’s changes. This combination ensures students are knowledgeable in traditional methods and ready for modern technological advancements.
Assessment methods for technical drawing in SS2 include practical assignments, where students create detailed drawings and projects; written tests to evaluate their understanding of theoretical concepts; and continuous assessment through class participation and exercises. Additionally, students may undergo practical examinations, demonstrating their proficiency with drawing instruments and CAD software.
