Teacher to support students to create informal and formal opportunities throughout learning experiences to share and challenge ideas with a range of others inside and outside of the school environment. Teacher should focus formative interactions on encouraging students to be self reflective and critical to ensure they move towards deeper more sophisticated understandings. Teacher supports students as they 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, and encourage links between other related curriculum areas to support deeper understandings.

Achievement Objectives

• Understand the role and nature of evidence and reasoning when managing risk through technological modelling.

Achievement Objectives

• Understand how materials are formed, manipulated, and transformed in different ways, depending on their properties, and understand the role of material evaluation in determining suitability for use in product development.

Achievement Objectives

• Understand the implications of subsystems for the design, development, and maintenance of technological systems.

Indicators

• Understand different forms of reasoning and how these provide for an understanding of risk.
• Understand the difference between possibility and probability and their role in risk exploration and management.
• Understand the strengths and weaknesses of more and less accurate model representations in terms of accuracy of prediction, error propagation, and robustness across contexts.
• Understand the limitations imposed on modeling from resources - particularly time and money.

Indicators

• Understand the implications of new material formulation possibilities (such as nanotechnologies) on future technological products.
• Understand how materials are manipulated and transformed to increase suitability for use in particular contexts.
• Understand how potential materials are evaluated to determine suitability for a products development.

Indicators

• Understand the purpose of subsystems in the development and communication of complex systems.
• Understand the advantages and disadvantages of subsystem use in system design, development and maintenance.
