Lesson Plan

• Describe the key stages of the design process and differentiate between iterative and intuitive design approaches.
• Explain how feedback loops and evidence‑based decisions drive iterative design.
• Evaluate when to apply intuitive design versus iterative design in product development.
• Apply a blended design workflow by sketching initial concepts and planning iterative prototyping.
• Reflect on documentation requirements for both approaches.

• Projector or interactive whiteboard
• Whiteboard and markers
• Student worksheets with comparative table
• Sketching paper and pencils
• CAD software access (e.g., Fusion 360) for prototype modelling
• Cardboard, tape and other low‑fidelity prototype materials
• Sticky notes for feedback loops

Show a short video of a product’s evolution and ask students what changes they notice. Link this to their prior experience of creating simple design briefs in earlier lessons. Explain that by the end of the session they will be able to distinguish iterative and intuitive design, justify their use, and plan a blended design approach.

1. Do‑now (5') – Students list examples of products that have improved over time.
2. Mini‑lecture (10') – Overview of the design process stages and introduction to iterative vs. intuitive design, using a flow‑chart diagram.
3. Comparative analysis (10') – In pairs, students complete a Venn diagram on the worksheet comparing the two approaches.
4. Guided activity (15') – Rapid intuitive sketching of a solution to a brief, then outline an iterative cycle (prototype, test, refine) on paper.
5. Prototyping sprint (15') – Teams build a low‑fidelity prototype with cardboard, test with peers, and record feedback on sticky notes.
6. Reflection & documentation (10') – Groups document iteration steps, evidence used, and note where intuition guided decisions.
7. Plenary (5') – Recap key points; exit ticket: write one advantage of iterative design and one advantage of intuitive design.

Summarise how iterative cycles improve reliability while intuitive ideas spark creativity. Collect the exit tickets to check understanding, and assign homework: each student creates a brief for a simple product and outlines an iterative plan, noting where intuitive decisions might be used.
