3-4 Band Description (VC)
In Levels 3 and 4, students explore digital systems in terms of their components and peripheral devices such as digital microscopes, cameras and interactive whiteboards. They collect, manipulate and interpret data, developing an understanding of the characteristics of data and their representation.
Students further develop their computational thinking skills using the concept of abstraction to analyse simple problems and use techniques such as summarising facts to deduce conclusions. They record simple solutions to problems through text and diagrams and develop their designing skills. They initially follow prepared algorithms, and progress to describing their own that support branching (choice of options) and user input. Their solutions are developed using appropriate software including visual programming languages that use graphical elements rather than text instructions.
With teacher guidance, students identify and list the major steps needed to complete a task or project. When sharing ideas and communicating in online environments they develop an understanding of why it is important to consider the feelings of their audiences and apply safe practices and agreed social protocols that demonstrate respectful behaviour.
Across the band, students will have had opportunities to create a range of digital solutions, such as interactive adventures that involve user choice, modelling simplified real-world systems and simple guessing games.
By the end of Level 4, students describe how a range of digital systems and their peripheral devices can be used for different purposes.
Students explain how the same data sets can be represented in different ways. They collect and manipulate different data when creating information and digital solutions. They plan and safely use information systems when creating and communicating ideas and information, applying agreed protocols.
Students define simple problems, and design and develop digital solutions using algorithms that involve decision-making and user input. They explain how their developed solutions and existing information systems meet their purposes.
