Curricular Competency
Applied Design
Understanding context
- Engage in a period of researchmay include traditional cultural knowledge and approaches of First Peoples and others, secondary sources, collective pools of knowledge in communities and collaborative atmospheresand empathetic observationmay include experiences; traditional cultural knowledge and approaches of First Peoples and those of other cultures; places, including the land and its natural resources and analogous settings; people, including users, experts, and thought leaders
Defining
- Identify potential users and relevant contextual factors
- Identify criteria for success, intended impact, and any constraintslimiting factors such as task or user requirements, materials, expense, environmental impact
- Determine whether activity is collaborative or self-directed
Ideating
- Screen ideas against criteria and constraints
- Critically analyze and prioritize competing factorsincluding social, ethical, and sustainabilityto meet community needs for preferred futures
- Maintain an open mind about potentially viable ideas
Prototyping
- Evaluate a variety of materials for effective use and potential for reuse, recycling, and biodegradability
- Make changes to tools, materials, and procedures as needed
Testing
- Identify sources of feedbackmay include First Nations, Métis, or Inuit community experts; keepers of other traditional cultural knowledge and approaches; peers, users, and other experts
- Develop an appropriate testconsider conditions, number of trials
- Conduct the test, collect and compile data, evaluate data, and decide on changes
- Iterate the design idea
Making
- Identify and use appropriate tools, technologiestools that extend human capabilities, materials, and processes
- Make a step-by-step plan and carry it out, making changes as needed
- Use materials in ways that minimize waste
Applied Skills
Demonstrate and document an awareness of precautionary and emergency safety procedures
Develop competency and proficiency in skills at various levels involving manual dexterity, mechanics, and maintenance
Identify the skills needed, individually or collaboratively, in relation to specific projects, and develop and refine them
Applied Technologies
Choose, adapt, and if necessary learn more about appropriate tools and technologies to use for tasks
Evaluate impacts
personal, social, and environmental
, including unintended negative consequences, of choices made about technology use
Evaluate the influences of land, natural resources, and culture on the development and use of tools and technologies
