Mark Scheme (AS Level)
Investigation and Clarification of Problem – 8 Marks
Comprehensive, organised range of sources of information including relevant practical investigations, taking into account current trends, available technologies and the needs of the client.
Perceptive analysis of information.
Comprehensive specification, well reasoned and based on research and investigation.
Development of Design Proposal – 24 Marks
Comprehensive, imaginative and feasible ideas.
Excellent development achieved through experimental and modelling work, taking into account available materials, technologies and production methods. All relevant sub-systems are identified and investigated.
Full explanation of all decisions made.
Comprehensive and detailed plan of making, including relevant quality control checks, in order to achieve a high quality outcome in the stated time.
Making and Modelling – 24 Marks
High level of making/modelling skills and accuracy, with ability to adapt theoriginal idea.
Planned quality control checks are applied throughout the making/modelling to ensure consistency and safety; all of the outcomes’ sub-systems function reliably and as a coherent whole.
Outcome satisfies all major points of the specification.
In-depth and detailed use of appropriate modelling strategies which help clarify the form of the prototype, system or product and production/manufacturing methods.
Evaluation and Testing – 12 Marks
Detailed and comprehensive testing strategy applied throughout with results used to inform the design and refine any modifications.
All aspects of the final prototype, system or product tested and evaluated against the specification.
Comments of others used appropriately to develop the prototype, system or product to improve the effectiveness of the final outcome.
Communication and Presentation – 12 Marks
Excellent level of communication and presentation, including competent use of appropriate technical language.
Excellent wide range of appropriate materials, techniques and media used to convey details of designing and making.
Complex ideas expressed extremely clearly and fluently in a structured and relevant way with few, if any, errors of grammar, punctuation and spelling.
