Combined C1 & C2 Examples
Aims
This criterion assesses the student’s ability to:
C1: present a range of annotated, feasible redesign ideas using an appropriate medium(s) to address the problem statement, which can be interpreted by others
C2: evaluate the redesign ideas against the design specifications through testing and user feedback
Overall Summary
Students are required to generate a diverse set of feasible ideas (ideation) that ultimately arrive at a design solution (modelling). After establishing the design opportunity, primary persona, problem statement and design specifications, students engage in ideation and modelling to explore a range of potential solutions.
Note on combining Criteria C1 and C2 together
You DO NOT have to do Criteria C1 and C2 seperately! You can combine them together. See the combined examples here.
Note on using AI to help ideation for Criteria C
Go to ChatGPT, Claude or CoPilot and write the following prompt, in addition to attaching your Design Specification:
I have been instructed to create a range of functionally different [your product here] that meet the attached design specification. Produce 10 ideas for me that are functionally different, that I would be able to create in a DT workshop in a secondary school.
The AI agent will the list you 10 ideas. Copy and paste each idea separately into Google Gemini with the following prompt:
[Paste the idea here] Draw a visual representation of this idea
Google Gemini will then produce a drawing/sketch of each of your 10 ideas. Ensure that you instruct Gemini in a new chat every time to ensure that it does not confuse between your ideas.
C1: Design Ideas
Pages: 1-2 pages, Words: 400-500
Students should use appropriate informal or formal sketches or drawings and digital or physical fidelity modelling to communicate their ideas visually. As the ideas are developed and refined, their feasibility is determined against the design specifications, which help determine the appropriate aspects of each idea.
The process of sketching or drawing design ideas involves an informal or formal approach that must address the key opportunities identified through the exploration of the persona and the task analysis. Performance requirements should also be addressed as part of the design specification.

C2: Modelling
Pages: 2-3 pages, Words: 700-800
The models created by students should be at appropriate levels of fidelity accuracy. Low-fidelity models are used to test general principles of an idea. Highly accurate fidelity models mimic the real product and are tested as they would be used by the target intended user(s).
Selecting the most appropriate idea should be validated against the performance and user requirements. To determine feasibility, the ideas are evaluated and tested based on the design specifications and feedback from intended user(s). This evaluation helps identify the most suitable idea that should be further developed in the next stage of the design process.

Combined C1 & C2 Examples
In these examples below, the students have done the ideation and modelling together (combined) as opposed to doing the drawings first, and then the modelling. This is a great approach to take if you'd like to develop each sketch further by evaluating it against user feedback.
