IBDP Design Technology SL
IB Diploma Programme Design Technology Standard Level is a Group 4 science subject that sits at the intersection of creative design thinking, materials science, engineering principles, and sustainability. This course challenges students to understand the full lifecycle of designed products — from the identification of human needs and the development of a design brief, through material selection, manufacturing processes, and modelling, to final production and critical evaluation. Students explore how designers balance competing demands: functional performance, aesthetic appeal, ergonomic suitability, environmental responsibility, and cultural appropriateness.The SL course is structured around four core units. Human Factors and Ergonomics develops students' understanding of anthropometrics, physical and cognitive ergonomics, and inclusive design principles. Resource Management and Sustainable Production examines the properties of metals, polymers, composites, smart materials, and textiles alongside manufacturing processes, life cycle assessment, and circular economy frameworks. Modelling covers physical prototyping, CAD, mathematical modelling, and rapid prototyping technologies. Final Production addresses production systems, quality management, tolerances, surface finishes, and health and safety.Beyond the core units, students engage with the iterative design process, design communication techniques, innovation and intellectual property, classic design movements, and user-centred evaluation methods. The course is assessed through two external papers — a multiple-choice paper and a data-based extended-response paper — and a substantial internal assessment design portfolio that accounts for 44% of the final grade. The portfolio requires students to demonstrate the complete design cycle, from problem identification to a tested and evaluated product.This AccelaStudy domain provides comprehensive preparation for all SL assessment components, with structured lessons, practice questions, design communication exercises, and exam-strategy guidance aligned to the IB assessment objectives and command terms.
