Level seven
Achievement objective
Students will understand how:
- the “should” and “could” decisions in technological modelling rely on an understanding of how evidence can change in value across contexts
- different tools are used to ascertain and mitigate risk.
Teacher guidance
To support students to develop understanding of technological modelling at level 7, teachers could:
- support students to explore how:
- context impacts on the perception of the validity of evidence presented. Therefore, shifting from one context to another can change the status of the evidence provided by technological modelling.
- and why different people and communities accept different types of evidence as valid. That is, the status given to evidence is dependent on a range of factors including ethical views and the perceived authority of people involved in the presentation of the evidence
- decisions underpinning technological modelling based on what should and could happen, rely on an understanding of how evidence gained may differ in value across contexts and/or communities
- technological modelling is used to ascertain and mitigate risk. Ascertaining risk involves establishing the probability of identified risks. Mitigation involves taking steps to reduce the probability of the risk being realised and/or severity of the risk should it be realised
- support students to analyse examples of technological modelling to understand how risk is ascertained and mitigated within particular technological developments
Examples should include the modelling practices of technologists and should include instances where modelling was undertaken to mitigate risk.
Indicators
Students can:
- discuss examples to illustrate why the status of evidence gained from technological modelling might change across contexts
