What students learn in AC9S9I06
This unit helps students build a clear, usable understanding of Assess the validity and reproducibility of methods and evaluate the.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: assess the validity and reproducibility of methods and evaluate the validity of conclusions and claims, including by identifying assumptions, conflicting evidence and areas of uncertainty.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- discussing what is meant by ‘validity’ and how the validity of information in secondary sources can be evaluated identifying gaps or weaknesses in conclusions and relating these to the validity and reproducibility of the method
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

- Content description: assess the validity and reproducibility of methods and evaluate the validity of conclusions and claims, including by identifying assumptions, conflicting evidence and areas of uncertainty
- E1: discussing what is meant by ‘validity’ and how the validity of information in secondary sources can be evaluated
- E2: identifying gaps or weaknesses in conclusions and relating these to the validity and reproducibility of the method
- E3: identifying assumptions in methods and determining the impact these could have on the validity of the conclusion
- E4: analysing methods and conclusions to identify facts or premises that are taken for granted to be true, and evaluating the reasonableness of those assumptions
- E5: considering if areas of uncertainty could lead to a viable alternative conclusion
- E6: considering how general practitioners manage conflicting evidence to diagnose illness

- Describing what is seen without connecting it to a question, pattern or prediction.
- Using everyday words only and missing simple scientific vocabulary.
- Changing more than one thing in an investigation, which makes the comparison unfair.
