Criterion B: Conceptual Design (9 marks)
What it tests: Your ability to develop and explore design ideas.
Performance Levels:
- High (7–9 marks): Comprehensive exploration with well-developed concepts.
- Medium (4–6 marks): Satisfactory exploration with some development.
- Low (1–3 marks): Limited exploration with minimal development.
Common Mistakes:
- Narrow range of ideas.
- Insufficient development of concepts.
Evidence to Show:
- Multiple design ideas with annotations.
- Development sketches or models.
Criterion C: Development of Detailed Design (9 marks)
What it tests: Your ability to refine a chosen concept into a detailed design.
Performance Levels:
- High (7–9 marks): Extensive detailing with clear production steps.
- Medium (4–6 marks): Adequate detailing with some preparation for production.
- Low (1–3 marks): Basic refinement without significant detail.
Common Mistakes:
- Lack of detailed drawings or specifications.
- Unclear production steps.
Evidence to Show:
- Detailed drawings with dimensions.
- Material and component specifications.
Criterion D: Testing and Evaluation (9 marks)
What it tests: Your ability to test and evaluate the final design solution.
Performance Levels:
- High (7–9 marks): Comprehensive testing with thorough evaluation against criteria.
- Medium (4–6 marks): Satisfactory evaluation with moderate testing.
- Low (1–3 marks): Limited evaluation with insufficient testing.
Common Mistakes:
- Inadequate testing methods.
- Lack of objective evaluation.
Evidence to Show:
- Documented testing procedures and results.
- Analysis of results against design specifications.
How to Interpret Your Grade from the Tool
The embedded grader will provide a score for each criterion, summing up to a total out of 36. Here's how to interpret your overall score:
- 32–36: Excellent understanding and application of design principles.
- 25–31: Good understanding with minor areas for improvement.
- 18–24: Satisfactory performance with noticeable areas for enhancement.
- 11–17: Basic understanding; significant improvements needed.
- 0–10: Limited understanding; major revisions required.
If you're between bands or uncertain:
- Review the specific feedback for each criterion.
- Focus on areas with the lowest scores for targeted improvements.
Improvement Actions:
- Criterion A: Enhance your research and clearly define design objectives.
- Criterion B: Expand the range of design ideas and develop them further.
- Criterion C: Provide detailed drawings and clear production plans.
- Criterion D: Implement comprehensive testing and objective evaluations.
Annotated Examples
High-Band Excerpt:
"The design opportunity was identified through extensive market research, highlighting a gap in ergonomic office furniture. Objectives were clearly defined to address user comfort and sustainability."
Why it scores high: Demonstrates thorough analysis and clear objectives derived from research.
Mid/Low-Band Excerpt:
"A problem was found in office chairs. Some ideas were considered to make them better."
What's missing: Lacks detailed analysis and clear objectives; ideas are not well-developed.
Grade Boundaries & Converting Your Mark
Grade boundaries can vary by session. As of the latest data, the following boundaries apply:
| Total Marks | Grade |
|---|---|
| 0–5 | 1 |
| 6–10 | 2 |
| 11–15 | 3 |
| 16–19 | 4 |
| 20–23 | 5 |
| 24–27 | 6 |
| 28–36 | 7 |
The IA contributes 40% to your final Design Technology SL grade. Ensure your IA score aligns with your overall grade goals.
Common Mistakes & Fast Fixes
- Mistake: Vague problem identification.
- Fix: Conduct thorough research to clearly define the design problem.
- Mistake: Limited design ideas.
- Fix: Brainstorm multiple concepts and explore each in detail.
- Mistake: Insufficient testing.
- Fix: Develop a comprehensive testing plan and document all results.
Subject-Specific Tips
- Material Selection: Choose materials that align with the design's function and sustainability goals.
- User-Centered Design: Engage with potential users throughout the design process for valuable feedback.
- Technical Drawings: Ensure all drawings are to scale and include necessary dimensions.
FAQs
Q: How long should my IA report be?
A: While there's no strict word count, aim for clarity and conciseness, typically around 20–30 pages.
Q: Can I include digital models instead of physical prototypes?
A: Yes, digital models are acceptable, but ensure they are detailed and accurately represent your design.
Q: How important is user feedback in the IA?
A: User feedback is crucial as it demonstrates the practical application and effectiveness of your design.
Q: Should I include cost analysis in my IA?
A: While not mandatory, a basic cost analysis can strengthen your evaluation and feasibility assessment.
Q: How do I handle unsuccessful tests?
A: Document all tests, successful or not, and discuss what was learned and how it informs future improvements.
Q: Can I work on a group project for the IA?
A: The IA is an individual assessment; however, you can seek feedback from peers during the process.
Q: How detailed should my production plan be?
A: Provide enough detail that someone else could replicate your design based on your plan.
**Q: Is it necessary to consider environmental impact in my design
