  Acquire, store and validate different types of data and use a range of software to interpret and visualise data to create information

  Elaborations

  • using digital systems to validate data, for example setting data types in a spreadsheet to make sure a date is input correctly
  • selecting and using peripheral devices suitable to the data type, for example using a data probe to collect numeric data about changing soil temperatures for plants, interpreting the data and sharing the results as a digital graph
  • recognising the difference between numerical, text and date formats in spreadsheets
  • using software to automate calculations to help with interpreting data, for example using functions to make arithmetic calculations using multiple cells and summing cell ranges
  • acquiring data from online sources by narrowing the focus, for example filtering data using provided options or performing queries using advanced search functions
  • using data visualisation software to help in interpreting trends, for example uploading data to a web application and building a visualisation of the dataset

• VCDTCD030

  Define problems in terms of data and functional requirements, drawing on previously solved problems to identify similarities

  Elaborations

  • checking existing solutions to identify features that are transferable to new but similar digital solutions, for example identifying if there are any similarities, such as user age and special requirements, between an existing game and a new game to be created
  • investigating characteristics of user interfaces that are common for particular types of problems, for example, touch screens encourage users to respond more intuitively than keyboards, or the consistent placement of symbols in games to speed up users' responses
  • using and interpreting data, establishing the root cause of a problem, for example using an annotated diagram to identify omissions, duplications or mismatches of data
  • describing in simple terms the nature of a problem and what a solution needs to achieve, for example what need the problem is associated with, who the solution is needed for, what data are needed and what features the solution would need to include

  Design a user interface for a digital system, generating and considering alternative design ideas

  Elaborations

  • exploring different features of user interfaces that allow people from different cultures to access information irrespective of language background, for example using icons and consistently placing icons or symbols in games interfaces to reduce the frustrations of game players
  • applying the principles and elements of design to a set of requirements in order to produce a user interface for a system that addresses an identified need, for example to emphasise or highlight an area of the screen to draw the viewer’s attention to an event or action
  • designing the user interface of a solution using different design tools, for example using a storyboard to outline the stages of a game or a mock-up to show the placement of icons
  • generating alternative design ideas for a user interface, for example sketching different concepts for a splash screen of a game or interactive multimedia experience or designing different user interfaces for people with visibility loss, taking into account size of icons and responsive font size

• VCDTDS026

  Examine the main components of common digital systems, and how such digital systems may connect together to form networks to transmit data

  Elaborations

  • describing digital systems as having internal and external components that perform different functions, for example external components for inputting data including keyboard, microphone, stylus; internal processing components include the central processing unit; external output components including speakers, projector, screen; and data and information storage components include cloud and external devices
  • explaining how data may be transmitted between two digital systems in different ways, for example that wires or cables are used in wired networks and radio waves are used to transfer data in wireless or mobile networks
  • investigating how the internal and external components of digital systems are coordinated to handle data, for example how a keyboard, central processing unit and screen work together to accept, manipulate and present data and information
  • identifying different types of networks that allow data to be sent between digital systems, for example wired, wireless and mobile
