What students learn in AC9S9I08

This unit helps students build a clear, usable understanding of And create texts to communicate ideas, findings and arguments effectively.... 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: write and create texts to communicate ideas, findings and arguments effectively for identified purposes and audiences, including selection of appropriate content, language and text features, using digital tools as appropriate.
  • Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
  • comparing and contrasting scientific texts addressing similar topics for different purposes or audiences, and analysing the author’s (or authors’) selection of content or use of language and text features writing a report on a scientific investigation including: an introductory paragraph that explains or references scientific theories, processes or other related knowledge that gives background information to the investigation; an explanation of the results obtained using scientific knowledge; and a discussion that considers validity and reproducibility
  • Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

Common mistakes to watch for

  • 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.
