IB Design Technology HL IA

Criterion B: Conceptual Design (9 marks)

Focus: Generating and developing design ideas.

• High Performance: Present multiple feasible ideas, use modeling to test concepts, and justify the final choice.
• Medium Performance: Generate some ideas with limited modeling; justification may be weak.
• Low Performance: Few ideas with little development or justification.

Criterion C: Development of a Detailed Design (9 marks)

Focus: Creating a detailed plan for the chosen design.

• High Performance: Provide detailed technical drawings, justify material and process choices, and outline a clear manufacturing plan.
• Medium Performance: Include technical drawings with some detail; justification and planning may be incomplete.
• Low Performance: Basic drawings with little detail; minimal justification and planning.

Criterion D: Testing and Evaluation (9 marks)

Focus: Assessing the prototype and suggesting improvements.

• High Performance: Implement a thorough testing strategy, analyze results against specifications, and propose detailed improvements.
• Medium Performance: Conduct testing with some analysis; improvement suggestions may lack depth.
• Low Performance: Minimal testing with little analysis or improvement suggestions.

Criterion E: Detailed Development of a Commercial Product (9 marks)

Focus: Adapting the design for commercial production.

• High Performance: Modify the design considering commercial manufacturing constraints, providing detailed drawings and models.
• Medium Performance: Some consideration of commercial production with partial modifications and documentation.
• Low Performance: Little to no consideration of commercial production aspects.

Criterion F: Making Choices for Commercial Production (9 marks)

Focus: Justifying decisions for commercial manufacturing.

• High Performance: Provide well-researched justifications for material and process choices, considering scale and cost.
• Medium Performance: Justify choices with some research; considerations may be incomplete.
• Low Performance: Little justification with minimal research.

How to Interpret Your Grade from the Tool

The embedded grader provides a mark for each criterion, which you can sum to determine your total IA score. This total can be compared against the grade boundaries to estimate your final grade.

• Between Bands: If your score is near the upper or lower limit of a band, focus on the specific criteria where you scored lower and consider how to enhance those areas.
  • Improvement Actions:
  • Criterion A: Enhance research depth and clarity in problem definition.
  • Criterion B: Develop more diverse ideas and utilize modeling techniques.
  • Criterion C: Provide detailed technical documentation and justify choices.
  • Criterion D: Implement comprehensive testing and analyze results thoroughly.
  • Criterion E: Consider commercial production constraints and adapt designs accordingly.
  • Criterion F: Conduct in-depth research to justify manufacturing decisions.

Annotated Examples

High-Band Excerpt:

"The design problem was identified through extensive user interviews and market analysis, leading to a detailed brief and comprehensive specifications. Multiple design ideas were generated, each evaluated through concept modeling and user feedback, culminating in a final design choice justified by its alignment with user needs and feasibility."

Why It Scores High: Demonstrates thorough research, diverse ideation, and strong justification, addressing multiple criteria effectively.

Mid/Low-Band Excerpt:

"A design problem was chosen based on personal interest, with a brief and specifications outlined. A few design ideas were sketched, and one was selected without extensive modeling or user feedback."

What's Missing: Lacks comprehensive research, diverse ideation, and justification, leading to lower scores in multiple criteria.

Grade Boundaries & Converting Your Mark

Grade boundaries can vary by examination session. It's essential to consult the latest IB documentation or your instructor for the most accurate information.
