Teacher to encourage students to create 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. Links should also be made to student opportunities to undertake Technological Practice and develop understandings of the Nature of Technology – both those in the past and future opportunities. That is, the understandings being developed should be used to reflect on past experiences and consider the implications for their future learning in technology. Teacher should guide students in selecting examples of technologies/technological development to ensure opportunity for the meeting of AOs.

Technological Modelling

Technological Products

Technological Systems

Achievement Objectives

• Understand that different forms of functional modelling are used to inform decision making in the development of technological possibilities and that prototypes can be used to evaluate the fitness of technological outcomes for further development.

Achievement Objectives

• Understand the relationship between the materials used and their performance properties in technological products.

Achievement Objectives

• Understand that technological systems are represented by symbolic language tools and understand the role played by the “black box” in technological systems.

Indicators

• Understand different forms that functional modelling can take. (e.g. thinking, talking, drawing, simulations, physical mock-ups etc)
  understand that different media used in modelling provide different types of evidence.
• Understand what evidence is required to evaluate fitness for purpose and how prototyping can best ensure evaluations are robust.

Indicators

• Explain how the properties of materials used in products relate to the performance requirements of the product.
• Suggest possible performance properties as based on the materials used in a product.
• Suggest possible materials suitable for use in a product as based on proposed performance requirements.

Indicators

• Understand representations of simple systems that use appropriate language tools.
• Understand a ‘black box’ as a means of representation that makes visible the inputs and outputs of a system, without showing any of that system’s inner workings.
• Understand the role of black boxes in systems and advantages and disadvantages associated with their use.
