Development ….. Notes to help in Assessing this stage
Aspect 1: creativity
Students should demonstrate originality in tackling the project or investigation. When addressing this criterion, teachers will need to ensure that projects and investigations have enough scope for innovation.
Many students fail to gain a “complete” mark for Aspect One of the development IA criteria due to lack of originality or innovation to help meet the “the need or opportunity” presented in the Planning stage. Often students merely redraw ideas seen in their research. Originality must be evident in the design ideas. This doesn’t mean that a totally new product must be designed. However it must be seen that students have considered their research carefully and integrated enough data and knowledge from this aspect of the project and incorporate it into their “new” designs. The design must involve innovation. A range of ideas must be drawn that address the original design problem and are seen to meet the brief and specification criteria.
It is important that students annotate their designs focusing on the particular originality or innovation. There must be evidence of radical and divergent thinking. This displays creativity and is concept and problem focused. Creative sketches/doodles may be the starting point for designing a solution but it needs to be drawn from their research.
Aspect 2: techniques
Techniques should be chosen that are appropriate to the task and provide evidence of innovative ideas. This may be in the form of detailed drawings, models (physical and/or CAD), tests, experiments.
Sketches and Design ideas need to be drawn pictorially with as much detail as required to graphically communicate their solutions. All design ideas should be clearly annotated linking directly to the set design specifications / information or data. From initial design ideas at least one idea should be further developed through several incarnations to further exploit innovative elements. Incremental Design improvements should be noted.
A Scale Model must be created to verify any human factor component and or moving part of the intended project. Partial evaluation of the feasibility of the project can also be evaluated. Photographs and or animation of the product can be taken to justify the innovation element of the project. Ergonomic and Human Factors annotation can further justify the project. Convergent thinking can be expressed in determining the final solution to the design problem.
Aspect 3: solution
The final solution needs to be described in appropriate detail. The solution may be the result of an experiment or the use of the design process to design a product or system. For a design project, the detailing must be sufficient for the solution to be realized, with materials and manufacturing techniques made explicit. Formal drawings should be produced in an appropriate format.
CAD Orthographic Drawing showing Top, Front and End Views. Fully Dimensioned, Material Lists and other standardized elements should be included eg 3rd Angle Projection symbol. Borders, Manufacturing/Construction details or sectional views shown where necessary etc
Exploded Isometric showing how all components are assembled and put together.
Pictorial Drawing fully rendered (Could be computer generated) showing all colour and details of any features especially highlighting any innovative aspect to the design. Annotated with full Design Specifications. A3 format
