A student:
Stage 2 of the Digital Technologies strand focuses on digital systems and how they transmit data. Students explore different types of data, have the opportunity to learn how to interpret patterns and develop skills in visual programming. Stage 2 of this strand further develops students’ knowledge and understanding of computational thinking and abstraction.

Focus question:
How do digital systems share information and instructions?
Students:
- identify and explore a range of digital systems and peripheral devices (ACTDIK007) ComT DesT SysT
- explore how digital systems transmit different types of data ComT SysT
- investigate digital and information systems, and explore how they meet personal, school or community needs SciT
Focus question: Why do we represent data in different ways?
Students:
- recognise that numbers, text, images, sounds, animations and videos are all forms of data when stored or viewed using a digital system (ACTDIK008) ComT SysT
- investigate how the same data can be represented in different ways, eg codes and symbols SciT
- collect, access and present different types of data using simple software to create information and solve problems, for example: ComT
− using software to sort and calculate data when solving problems, eg calculations in spreadsheets
- plan, create and communicate ideas and information, applying agreed ethical and social protocols (ACTDIP013) ComT SysT
Focus question: How are algorithms used to develop digital systems?
Students:
- describe and follow a sequence of steps and decisions (algorithms) to solve defined problems involving branching and user input, for example: ComT DesT SysT
− create and follow algorithms using branching
- design and produce digital solutions using a visual programming language (ACTDIP011) ComT DesT
