Home » SSS1 Scheme of Work » SSS1 Technical Drawing Scheme of Work
Technical Drawing is a key part of science and technical education. It teaches students how to create accurate and detailed drawings of objects, buildings, and systems. This subject helps students develop skills to visualize and communicate ideas through drawings, which are important in engineering, architecture, and industrial design.
The Lagos State Unified Scheme of Work for Technical Drawing in SS1 is carefully designed to teach students the basics of technical drawing. It covers topics such as geometric constructions, orthographic projections, isometric drawings, and how to use drawing tools and materials. Each topic builds on what students have previously learned, helping them move from simple to more complex ideas step by step.
Studying Technical Drawing in SS1 with this scheme gives students a strong and thorough introduction to the subject. It provides the important skills and knowledge needed for future studies and careers in engineering, architecture, and other technical fields.
At the end of the SSS1 session, students can;
Assessment methods for technical drawing in SSS1 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.
