What is “Iterate”?
This stage of the iSTEM engineering design process requires students to continuously improve their design. Which changes will produce a better result? Can you improve the design’s functionality? Are the more ideas that can be incorporated into the design?
Use the lesson below to commence solving one of the following scenarios
- Earth Observation
- Home on the Moon
- Growing food in space
- AI in Space
Key Questions for Students to consider
- Do we need to revisit earlier phases of the process?
- Has the identified problem or need changed?
- Has the solution produced other opportunities?
- How can the solution be further improved?
- If you decide to make revisions, what will it look like?
- Are there plans and enough resources to make revisions
- Assess previous iterations of the design solution.
- Repeat, design, prototype and evaluate, until the ‘best possible solution’ is achieved.
- Refine design ideas based on results of experimentation, testing and evaluation.
- Produce a minimal viable product (MVP) after numerous iterations of the design solution.
Suggested Learning Sequence – Mission 8
Our expert curriculum designers have developed a suggested Mission 8 learning sequence for teachers. The following is for the full set of AVA resources, however, teachers are encouraged to only use activities that are most suitable for their own class and school setting.
Sub Mission 2: Iterate Provide students with this worksheet and get them to sketch and annotate four different improvements or iterations of their previous design solution.
Sub Mission 3: Iterate Drawing Provide students with this worksheet and ask them to draw a new iteration of their design solution combining some of their ideas from the previous exercise. Get students to annotate their drawings to provide descriptions of the improvements.
Sub Mission 4: More Drawings Provide students with these worksheets and ask them to produce a series of drawings of their newly iterated design. Get students to produce a top and side view orthographic drawing, a pictorial drawing and an isometric drawing using the iso grid. Students should annotate their drawings.
Sub Mission 5: Final Design Provide students with this worksheet. Ask students to complete the final annotated drawing of their design solution.
Sub Mission 6: Scenarios Get students to watch the selected videos from their selected scenario to provide additional context for their project.
Iterate – Ortho, Pictorial, Iso Drawing
In these worksheets students are to produce a range of drawing including Orthographic, Pictorial and Isometric projections of the new design iteration.
