Design
KS3DT-KS3-D001
Using research and exploration to identify and solve own design problems; developing and communicating design ideas using annotated sketches, detailed plans, 3D and mathematical modelling, and computer-aided design.
National Curriculum context
At KS3, design becomes genuinely self-directed: pupils are expected to identify and solve their own design problems rather than working to given briefs. This autonomy marks a significant shift from KS2, where the design brief was typically provided. Pupils are expected to conduct in-depth research and exploration - including user research, existing product analysis, material investigation and contextual study - to identify authentic user needs and opportunities. Design specification becomes more rigorous, articulating measurable criteria against which final products can be evaluated. Communication through multiple representational modes, including annotated sketches, formal technical drawings, scale models, 3D computer modelling and mathematical modelling of structural or mechanical properties, equips pupils with the full toolkit of professional designers.

Apply user-centred design processes to develop and communicate solutions
practice CuratedUser-centred design is the sole concept in the KS3 Design domain. It integrates the full design process at this stage — research, ideation, communication, prototyping — around a central philosophy of designing for real users. A single cluster correctly represents the domain.

Study units and activities that deliver concepts in this domain.
3D Printing: Design for Additive Manufacture
Design & Technology Design, Make, EvaluatePedagogical rationale
3D printing introduces additive manufacture -- building objects layer by layer rather than cutting from a block. Pupils learn 3D CAD modelling, understand the capabilities and limitations of FDM printing (layer resolution, support structures, infill percentage), and design products that exploit the unique advantages of additive manufacture (complex geometries impossible by subtractive methods). This is the most industry-relevant emerging technology in the KS3 DT curriculum.
CAD/CAM: Laser-Cut Clock
Design & Technology Design, Make, EvaluatePedagogical rationale
A laser-cut clock is the ideal introduction to CAD/CAM because the product is flat (suitable for 2D cutting), requires precise geometry (the clock mechanism needs an exact hole), and has both functional and aesthetic dimensions. Pupils learn to use 2D design software, convert designs to machine-readable files, and operate a laser cutter. The project demonstrates that digital manufacturing produces results impossible by hand (intricate patterns, precise tolerances).
Electronic Systems: Night Light with Microcontroller
Design & Technology Design, Make, EvaluatePedagogical rationale
A night light that responds to ambient light levels (using an LDR sensor and microcontroller) is the simplest embedded computing project and the natural progression from KS2 simple circuits. Pupils learn that products can sense their environment and respond intelligently -- the core principle of embedded computing. Programming the microcontroller (Arduino or micro:bit) to read sensor input and control LED output teaches input-process-output in a physical context.
Resistant Materials: Phone/Tablet Stand
Design & Technology Design, Make, EvaluatePedagogical rationale
A phone or tablet stand is a small, achievable resistant materials project that introduces marking out, cutting, shaping and finishing in wood, metal or acrylic. The product has an immediate real-world use that motivates quality finishing. The design challenge -- holding a device at a comfortable viewing angle while being stable -- naturally introduces ergonomics and basic structural analysis. Pupils can apply CAD to generate a template before making.
Sustainable Design Challenge: Upcycled Product
Design & Technology Design, Make, EvaluatePedagogical rationale
An upcycling design challenge forces pupils to work within material constraints -- the available waste materials define the design possibilities. This teaches sustainable design thinking: considering the environmental impact of material choices, the lifecycle of products, and the concept of circular design. Pupils investigate real-world sustainability issues (plastic waste, fast fashion, planned obsolescence) and respond with a designed product that gives waste materials a new, functional life.
Textiles: Drawstring Bag with Surface Decoration
Design & Technology Design, Make, EvaluatePedagogical rationale
A drawstring bag introduces secondary textiles skills: using a sewing machine, working with multiple fabric layers, and applying surface decoration techniques (applique, fabric printing, embroidery). The design brief requires pupils to research a target user and create a product that meets specific functional and aesthetic requirements. This project builds directly on KS2 hand-sewing and introduces the precision and speed of machine-sewn construction.

User-Centred Design
process Guided MaterialsDT-KS3-C001
User-centred design is a design philosophy and process that places the needs, capabilities, preferences and context of intended users at the centre of every design decision. It involves deep empathy with users, structured research methods (interviews, observation, surveys, prototyping), iterative testing with real users, and continuous refinement based on user feedback. At KS3, pupils develop understanding of user-centred design as a distinct and powerful approach that produces solutions better suited to genuine human needs than solutions derived purely from technical or aesthetic assumptions.
Teaching guidance
Introduce user research methods: structured interviews, observation, persona development, user journey mapping. Set projects where pupils must engage with real potential users before and during the design process. Teach prototyping as a user testing tool, not just a making exercise. Discuss famous examples of user-centred design (and failures caused by ignoring users). Develop pupils' ability to translate qualitative user insights into quantitative design criteria. Connect to real professional practice: how do product companies discover user needs?
Common misconceptions
Pupils may assume they understand user needs without researching them; conducting actual user research and discovering unexpected insights challenges this assumption. Pupils may treat prototyping as the production of a miniature final product rather than as a testing tool; emphasising that prototypes are for learning, not perfecting, changes the approach. The idea that design can be improved through testing can seem obvious but requires practical experience to become a genuine habit.
Difficulty levels
Recognises that designers should think about who will use a product, but relies on personal assumptions rather than structured research to identify user needs.
Example task
A company wants to design a new water bottle for secondary school students. List three things you would want to find out about the users before designing the bottle.
Model response: I would want to find out: 1) How much water students typically drink during the school day, 2) Whether they carry it in a bag or by hand (so I know if it needs to be leak-proof and what size), 3) What features they find annoying about their current water bottles.
Can describe user-centred design methods such as interviews and observation, and begins to use them to create a basic design specification, though research may be shallow.
Example task
Design a short interview (4 questions) you would use to understand the needs of elderly users for a new kitchen gadget. Explain why each question is useful.
Model response: 1) 'What kitchen tasks do you find most difficult?' — identifies genuine pain points rather than my assumptions. 2) 'Do you have any conditions that affect your grip or reach?' — ensures I design for physical accessibility. 3) 'Can you show me how you currently do this task?' — observation reveals problems users may not mention. 4) 'What would make this task easier for you?' — captures user priorities in their own words. These questions focus on needs rather than solutions, so I design based on evidence.
Conducts structured user research, develops user personas, translates findings into measurable design criteria, and uses iterative prototyping to test ideas with real users.
Example task
You are designing a phone stand for a hospital reception desk. Describe the full user-centred design process you would follow, from research to prototype testing.
Model response: First, I would observe the reception area to understand the environment: desk height, lighting, how staff use their phones during work, and what problems arise (phone falling, poor viewing angle, cables tangling). I would interview reception staff using open questions about their needs and frustrations. From this research I would create a user persona summarising key needs and constraints. I would then write a design specification with measurable criteria: must hold phones 60-85mm wide, must allow charging cable access, must be stable on a desk with vibrations from passing trolleys. I would generate multiple design ideas using annotated sketches, select the most promising, and create a rapid prototype from card. I would take this prototype to the reception desk and ask staff to try it during their shift, noting any problems. Based on their feedback, I would modify the design and re-test — repeating this iterate-test cycle at least twice before committing to a final design.
Critically evaluates competing user needs and design trade-offs, applies professional design thinking frameworks, and justifies design decisions with reference to user research evidence.
Example task
Two user groups will use your product: visually impaired users need large tactile controls, but teenage users want a sleek, minimal design. How would a user-centred designer resolve this conflict?
Model response: A user-centred designer would recognise this as a design tension, not a choice between groups. First, I would investigate whether the tension is real by researching inclusive design examples where accessibility features are integrated seamlessly — for instance, the OXO Good Grips range, designed for arthritis sufferers, became popular with all users because comfortable grip benefits everyone. I would explore design solutions that serve both needs: tactile feedback through subtle material texture differences rather than large protruding buttons; haptic vibration feedback; voice control as an alternative input mode. I would prototype multiple approaches and test with both user groups, measuring both usability (can visually impaired users operate it independently?) and desirability (do teenage users find it attractive?). The resolution likely involves reframing the brief: 'minimal' does not mean 'featureless' — it means removing unnecessary complexity while retaining essential functionality. The best inclusive designs make the accessible features invisible to users who do not need them while essential for those who do.
