Design criteria, constraints and specifications

Technologies · Year 9

Name: ______________________Date: ____________

Design criteria, constraints and specifications develops how measurable requirements guide fair design decisions. Students move from a defined need through planning and modelling to evidence-based testing, iteration and evaluation of consequences.

Example

A strong design criteria, constraints and specifications solution makes its assumptions visible, meets measurable criteria and changes when testing reveals a weakness.

Key terms

Criterion:
A core idea used when working with Design criteria, constraints and specifications.
Constraint:
A second design or digital concept relevant to Design criteria, constraints and specifications.
Specification:
A way to describe or evaluate Design criteria, constraints and specifications.

Questions

  1. 1. What is the central idea in design criteria, constraints and specifications?

    • how measurable requirements guide fair design decisions
    • Build before understanding the user or need.
    • Treat the first prototype as finished.
    • Ignore safety, accessibility, privacy and sustainability.
  2. 2. Which term means "A core idea used when working with Design criteria, constraints and specifications."?

    • Criterion
    • Constraint
    • Specification
    • Context
  3. 3. Which term means "A second design or digital concept relevant to Design criteria, constraints and specifications."?

    • Constraint
    • Criterion
    • Specification
    • Evidence
  4. 4. Which term means "A way to describe or evaluate Design criteria, constraints and specifications."?

    • Specification
    • Criterion
    • Constraint
    • Reflection
  5. 5. Which task best practises design criteria, constraints and specifications?

    • Write and prioritise criteria and constraints for a familiar product.
    • Build before understanding the user or need.
    • Treat the first prototype as finished.
    • Ignore safety, accessibility, privacy and sustainability.
  6. 6. Which approach best supports learning in Technologies?

    • Define the need, plan against criteria, prototype safely, test with evidence and improve for users and impact.
    • Build before understanding the user or need.
    • Treat the first prototype as finished.
    • Ignore safety, accessibility, privacy and sustainability.
  7. 7. Why is a worked example useful?

    • It makes the reasoning and deliberate choices visible.
    • It removes the need to think.
    • It guarantees every new problem is identical.
    • It replaces practice completely.
  8. 8. Which response applies how measurable requirements guide fair design decisions?

    • Write and prioritise criteria and constraints for a familiar product.
    • Build before understanding the user or need.
    • Treat the first prototype as finished.
    • Ignore safety, accessibility, privacy and sustainability.
  9. 9. What makes guided practice useful?

    • It gives support while the learner tries the thinking for themselves.
    • It supplies answers before any attempt.
    • It avoids feedback and reflection.
    • It makes the final check unrelated.
  10. 10. How should the key terms support design criteria, constraints and specifications?

    • They should make the explanation more precise and connected to evidence.
    • They should be listed without meaning.
    • They should replace examples.
    • They should be used only for spelling.
  11. 11. What is the best response when a first attempt is incomplete?

    • Use feedback or evidence to revise the reasoning.
    • Hide the attempt.
    • Repeat it without checking.
    • Choose an unrelated answer.
  12. 12. Which explanation is strongest?

    • A clear idea supported by a relevant example and reasoning.
    • A claim with no support.
    • A copied definition only.
    • A long response that avoids the question.
  13. 13. Why transfer the skill to a new example?

    • It shows whether the understanding can be used beyond the worked model.
    • It proves all examples are identical.
    • It makes the original lesson unnecessary.
    • It prevents reflection.
  14. 14. What should a checkpoint reveal?

    • Whether the learner is ready for the final check or needs another explanation.
    • Only whether the learner worked quickly.
    • Whether the topic title was memorised.
    • Nothing about understanding.
  15. 15. What makes a conclusion responsible?

    • It matches the evidence and acknowledges important limits.
    • It claims more than the evidence shows.
    • It ignores alternatives.
    • It is decided before the task.
  16. 16. How can design criteria, constraints and specifications support independent learning?

    • It gives a repeatable way to interpret, create, solve or evaluate a new situation.
    • It works only for the example already shown.
    • It removes the need for judgement.
    • It depends on guessing.
  17. 17. What should happen when evidence challenges the first interpretation or method?

    • Review the reasoning and revise it when the evidence warrants change.
    • Discard the evidence automatically.
    • Keep the first answer regardless.
    • Stop checking the work.
  18. 18. Which reflection leads to useful improvement?

    • Identify a successful choice, evidence of its effect and one specific next step.
    • State only that the task was easy or hard.
    • List the title again.
    • Avoid referring to the work.
  19. 19. What distinguishes strong Year 9 Technologies work?

    • Accurate knowledge, deliberate choices, evidence and clear reasoning.
    • Length without relevance.
    • Confidence without checking.
    • Memorisation without application.
  20. 20. Why should an application task remain manageable but substantial?

    • It should provide enough challenge to demonstrate real learning without creating unnecessary overload.
    • It should remove all challenge.
    • It should be long regardless of purpose.
    • It should repeat the quiz word for word.
  21. 21. What is the strongest outcome from design criteria, constraints and specifications?

    • Use how measurable requirements guide fair design decisions accurately in a purposeful new context.
    • Build before understanding the user or need.
    • Treat the first prototype as finished.
    • Ignore safety, accessibility, privacy and sustainability.
