Data representation

This Content Descriptor from Year 9 Technologies provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

Content Descriptor

represent documents online as content (text), structure (markup) and presentation (styling) and explain why such representations are important

Elaborations

  • • representing documents by separating the content (the text in the document), the structure (the document structure such as headings and paragraphs) and presentation (how the document is laid out and styled)
  • • writing web pages using HyperText Markup Language (HTML) for the content and structure and Cascading Style Sheets (CSS) for styling the page and explaining how HTML tags separate content from structure
  • • explaining how representing content, structure and presentation separately allows each of them to be designed, edited, manipulated and stored independently of the others and why this is important

Achievement Standard This Supports

This Content Descriptor contributes to the following Achievement Standard:

Year 9 ASTECTDIY910
Year 9 Technologies Achievement Standard
By the end of Year 10 students develop and modify innovative digital solutions, decompose real-world problems, and critically evaluate alternative solutions against stakeholder elicited user stories. Students acquire, interpret and model complex data with databases and represent documents as content, structure and presentation. They design and validate algorithms and implement them, including in an object-oriented programming language. Students explain how digital systems manage, control and secure access to data; and model cyber security threats and explore a vulnerability. They use advanced features of digital tools to create interactive content, and to plan, collaborate on and manage agile projects. Students apply privacy principles to manage digital footprints.
