    Topic Overview

    This topic explores how designers critically evaluate new and emerging technologies—such as AI, 3D printing, smart materials, and biotechnology—to inform their design decisions. You'll learn to assess these technologies from multiple perspectives, including ethics, environmental impact, economics, and social implications. Understanding this evaluation process is crucial because it ensures that design choices are responsible, sustainable, and aligned with future societal needs.

    In the WJEC GCSE Design and Technology course, this topic sits within the 'Designing and Making Principles' section. It requires you to think beyond the immediate function of a product and consider its wider consequences. For example, when designing a smartphone, you must evaluate the ethical implications of rare earth mineral mining, the environmental cost of e-waste, and the social impact of planned obsolescence. This critical thinking helps you become a more thoughtful and innovative designer.

    Why does this matter? Because technology is advancing rapidly, and designers have a responsibility to shape its direction. By evaluating technologies critically, you can anticipate potential problems—like job displacement due to automation or privacy concerns with smart devices—and design solutions that mitigate these issues. This topic also prepares you for the non-exam assessment (NEA), where you'll need to justify your design decisions with reference to these broader perspectives.

    Key Concepts

    Core ideas you must understand for this topic

    • →Ethical perspectives: Consider moral issues such as data privacy, intellectual property, fair trade, and the impact on workers' rights when using new technologies.
    • →Environmental perspectives: Evaluate the full lifecycle of a product—from raw material extraction to disposal—including energy use, carbon footprint, recyclability, and pollution.
    • →Social perspectives: Assess how technology affects people's lives, including health, wellbeing, social interaction, and equality of access (digital divide).
    • →Economic perspectives: Analyse costs and benefits, including manufacturing costs, market demand, job creation vs. job loss, and long-term value for money.
    • →Future scenarios: Use foresight techniques like trend analysis and scenario planning to predict how emerging technologies might evolve and shape society.

    What You Need to Demonstrate

    Key skills and knowledge for this topic

    • Understanding of sustainability and environmental issues in design and manufacture
    • Application of the SIX R's (rethink, reuse, recycle, repair, reduce, refuse)
    • Use of Life Cycle Analysis (LCA) to determine environmental impact
    • Understanding of Fair-trade policies and carbon/ecological footprints
    • Consideration of social, cultural, economic, and environmental responsibilities

    Marking Points

    Key points examiners look for in your answers

    • Understanding of sustainability and environmental issues in design and manufacture
    • Application of the SIX R's (rethink, reuse, recycle, repair, reduce, refuse)
    • Use of Life Cycle Analysis (LCA) to determine environmental impact
    • Understanding of Fair-trade policies and carbon/ecological footprints
    • Consideration of social, cultural, economic, and environmental responsibilities

    Examiner Tips

    Expert advice for maximising your marks

    • 💡Always justify design decisions by referencing environmental or ethical impacts
    • 💡Use the SIX R's as a framework when evaluating existing products or your own designs
    • 💡Be prepared to discuss how future scenarios (e.g., resource scarcity) might change design requirements
    • 💡Ensure you can explain the difference between carbon footprint and ecological footprint
    • 💡Use specific examples: When discussing ethics, mention real cases like the use of conflict minerals in electronics or the ethical concerns of facial recognition technology. This shows depth of knowledge.
    • 💡Structure your evaluation: For any technology, systematically consider each perspective (ethical, environmental, social, economic) in separate paragraphs. Use connectives like 'however' and 'on the other hand' to show critical thinking.
    • 💡Link to design decisions: Always explain how your evaluation influences a design choice. For example, 'Because of the ethical issues with child labour in cobalt mining, I would design a phone with a recyclable battery that uses alternative materials.'

    Common Mistakes

    Pitfalls to avoid in your exam answers

    • Failing to link environmental considerations to specific design decisions
    • Superficial understanding of the SIX R's without practical application
    • Ignoring the social or ethical implications of design choices
    • Inability to apply Life Cycle Analysis to a specific product
    • Misconception: 'New technology is always better for the environment.' Correction: While some technologies reduce waste (e.g., 3D printing), others increase energy consumption or use rare materials. Always evaluate the full lifecycle.
    • Misconception: 'Ethics only applies to controversial topics like AI weapons.' Correction: Ethics applies to everyday design decisions, such as using sustainable materials or ensuring products are repairable (right to repair).
    • Misconception: 'Economic factors are the most important in design.' Correction: In the WJEC specification, you must balance economic, ethical, environmental, and social factors equally—marks are awarded for a holistic evaluation.
