Teacher to support students to create informal and formal opportunities throughout learning experiences to share and challenge ideas with others. Teacher should focus formative interactions on encouraging students to be self reflective and critical to ensure they move towards deeper more sophisticated understandings. Teacher encourages students to make links to past experiences and consider the implications for their future learning in technology. Teacher should challenge students to justify their selection of examples of technologies/technological development as providing opportunity for meeting task requirements.

Technological Modelling

Technological Products

Technological Systems

Achievement Objectives

• Understand how evidence, reasoning, and decision making in functional modelling contribute to the development of design concepts and how prototyping can be used to justify ongoing refinement of technological outcomes.

Achievement Objectives

• Understand how materials are selected, based on desired performance criteria.

Achievement Objectives

• Understand the properties of subsystems within technological systems.

Indicators

• Understand the role of evidence in justifying decisions made from functional modelling.
• Understand decision making strategies that employ reasoning focused on whether outcomes can be realised alongside whether they should be realised.
• Understand how prototyping can be used to justify on-going refinement/optimization of technological outcomes.

Indicators

• Understand how materials are evaluated against performance criteria in order to select possible resources for product development.
• Understand how materials change in processing and production and how this impacts on selection criteria.
• Understand the concept of minimal engineering and how this informs material selection and the design of products.

Indicators

• Understand the generic and specialized properties of subsystems as they serve to function within more complex technological systems.
• Understand how subsystems allow for the protection of system malfunction or the damage of parts, through such things as back up subsystems or shutdown options.
