Technical drawing in SSS3 (Senior Secondary School 3) is a specialized 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 SSS3, the Lagos State unified scheme of work for technical drawing builds on what students learned in SSS2. 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, SSS3 students become skilled in using drawing tools and software. The course emphasizes manual drawing techniques and computer-aided design (CAD) tools, keeping up with the field’s changes. This combination ensures students know traditional methods and are ready for excellence in their WASSCE.
SSS3 students in Nigeria are assessed in Technical drawing through continuous assessments and the WASSCE. Continuous assessments include class tests, assignments, projects, and class participation. Students are evaluated on their ability to create accurate technical sketches, interpret engineering drawings, and use drafting tools proficiently. These assessments measure academic knowledge and practical competencies demonstrating the application of learned principles in real-world scenarios.
