  Collect, sort, and recognise, with assistance, different types of patterns in data, and use digital systems to represent data as pictures, symbols and diagrams

  Elaborations

  • collecting, sorting and displaying data in a personally meaningful way, for example collecting leaves, sorting them into groups based on size, shape or colour and using a drawing program to represent the findings
  • sorting like objects based on a given classification, for example group shoes based on colour or size and presenting the findings
  • examining and continuing a simple repeated pattern with given objects, movement or sounds
  • using common software to present ideas creatively, for example creating a slideshow, poster, drawing or image about a wishful holiday destination

• VCDTDI036

  Investigate how digital systems represent text, image and sound data in binary

  Elaborations

  • explaining that characters in text correspond to numbers defined by the character set, for example ‘A’ corresponds to 65 in the ASCII and Unicode character sets
  • recognising that Unicode attempts to represent the written symbols of every language; and using Unicode charts to look up characters from Asian writing systems
  • investigating the different representation of bitmap and vector graphics and its consequences, for example pixelation in magnified bitmap and vector images
  • investigating how colours are represented in images and videos, for example manipulating red, green and blue (RGB) colours in an image editor
  • converting between decimal and 8-bit (1 byte) unsigned binary, covering whole numbers typically used for characters and RGB, for example 65 in decimal is 01000001 in 8-bit binary
  • explaining ways media elements are presented, for example the difference between embedded and linked media elements

  Develop and modify programs with user interfaces involving branching, iteration and functions using a general-purpose programming language

  Elaborations

  • developing and modifying digital solutions by implementing instructions contained in algorithms using a programming language
  • developing a digital game that manipulates models of real-world objects
  • programming a robot to recognise particular objects and to treat them differently, for example to choose objects based on colour
  • creating digital solutions that provide user navigation and prompts with controlled repetitions, for example an information kiosk that has layers of buttons and prompts the user three times before returning to the beginning

• VCDTDI021

  Collect, access and present different types of data using simple software to create information and solve problems

  Elaborations

  • selecting appropriate formats or layout styles to present data as information depending on the type of data and the audience, for example graphs suit data that shows trends or comparisons; lists suit text data that needs to be presented in alphabetical order; animations suit images that show actions and relationships
  • using different techniques to present data as information, for example creating a column chart in a spreadsheet by colouring cells to represent different items
  • improving the appearance and usability of data, for example using colour, headings and labelling of images to organise and accurately identify data
  • using software to sort and calculate data when solving problems, for example sorting numerical data in ascending or descending order and automating simple arithmetic calculations using nearby cells and summing cell ranges in spreadsheet or database software
  • exploring different online sources to access data, for example using online query interfaces to select and retrieve data from an online database such as a library catalogue or weather records
  • recognising that all types of data are stored in digital systems and may be represented in different ways such as files and folders with names and icons

• VCDTDI008

  Collect, sort and recognise simple patterns in data, and assist with the use of digital systems to represent data as pictures and symbols

  Elaborations

  • pairing identical objects from a small collection
  • copying a pattern associated with a familiar activity, for example repeating a movement pattern
  • matching, sorting and organising objects in practical situations
  • sorting objects and events based on easily identified characteristics and using digital systems to represent data, for example sorting objects based on colour or shape and creating a digital drawing
  • assisting to collect and sort data in a structured situation, for example questioning friends about their favourite animal or football team and selecting an image of the most popular response
  • assisting in using common software to present data creatively such as a slideshow, movie or sounds

  Design the user experience of a digital system, generating, evaluating and communicating alternative designs

  Elaborations

  • designing the user interface of a solution using a range of design tools, for example using a storyboard to explain the stages of a game, and wire-frames and mock-ups to describe the appearance of a solution
  • identifying features that make an effective game, such as storyline, goal, reward, gameplay and environment
  • identifying similar digital systems and their user interfaces, assessing whether user interface elements can be re-used
  • devising criteria and comparing alternative design ideas that address a problem, for example evaluating two design outlines on the basis of attractiveness, ergonomics, ease of use, emotional satisfaction and accessibility
  • applying the principles and elements of design to a series of solutions to evaluate the success of each solution in holding the viewer’s attention, for example identifying which colour combinations or framing of visual elements keep different audiences engaged with on-screen activity
