Big Ideas
Design for the life cycle
taking into account economic costs, and social and environmental impacts of the product, from the extraction of raw materials to eventual reuse or recycling of component materials
includes consideration of social and environmental impacts including manufacturing, packaging, disposal, and recycling considerations
.
Personal design interests require the evaluation and refinement of skills.
Tools and technologies
tools that extend human capabilities
can be adapted for specific purposes.

Curricular Competency
Applied Design
Understanding context
- Engage in a period of user-centred researchresearch done directly with potential users to understand how they do things and why, their physical and emotional needs, how they think about the world, and what is meaningful to themand empathetic observationaimed at understanding the values and beliefs of other cultures and the diverse motivations and needs of different people; may be informed by experiences of people involved; traditional cultural knowledge and approaches; First Peoples worldviews, perspectives, knowledge, and practices; places, including the land and its natural resources and analogous settings; experts and thought leaders
Defining
- Establish a point of view for a chosen design opportunity
- Identify potential users, intended impacts, and possible unintended negative consequences
- Make inferences about premises and constraintslimiting factors, such as task or user requirements, materials, expense, environmental impactthat define the design space, and identify criteria for success
- Determine whether activity is collaborative or self-directed
Ideating
- Generate ideas and add to others' ideas to create possibilities, and prioritize them for prototyping
- Critically analyze how competing social, ethical, and sustainability considerations impact creation and development of solutions
- Choose an idea to pursue based on success criteria and maintain an open mind about potentially viable ideas
Prototyping
- Choose a form for prototyping and develop a planfor example, pictorial drawings, sketches, flow chartsthat includes key stages and resources
- Analyze the design for the life cycle and evaluate its impactsincluding social and environmental impacts of extraction and transportation of raw materials; manufacturing, packaging, and transportation to markets; servicing or providing replacement parts; expected usable lifetime; and reuse or recycling of component materials
- Visualize and construct prototypes, making changes to tools, materials, and procedures as needed
- Record iterationsrepetitions of a process with the aim of approaching a desired resultof prototyping
Testing
- Identify and communicate with sources of feedbackmay include peers; users; First Nations, Métis, or Inuit community experts; other experts and professionals both online and offline
- Develop an appropriate testincludes evaluating the degree of authenticity required for the setting of the test, deciding on an appropriate type and number of trials, and collecting and compiling dataof the prototype, conduct the test, and collect and compile data
- Apply information from critiques, testing results, and success criteria to make changes
Making
- Identify appropriate tools, technologies, materials, processes, cost implications, and time needed
- Create design, incorporating feedback from self, others, and results from testing of the prototype
- Use materials in ways that minimize waste
Sharing
- Determine how and with whom to sharemay include showing to others or use by others, giving away, or marketing and sellingdesign and processes for feedback
- Share the product with users to evaluate its success
- Critically reflect on plans, products and processes, and identify new design goals
- Analyze new possibilities for plans, products and processes, including how they or others might build on them
Applied Skills
Apply safety procedures for themselves, co-workers, and users in both physical and digital environments
Individually or collaboratively identify and assess skills needed for design interests
Demonstrate competency and proficiency in skills at various levels involving manual dexterity and circuitry techniques
Develop specific plans to learn or refine identified skills over time
Applied Technologies
Explore existing, new, and emerging tools, technologies, and systems to evaluate suitability for design interests
Evaluate impacts, including unintended negative consequences, of choices made about technology use
Examine the role that advancing technologies play in electronics-related contexts
