Data representation using binary

What is this about?

Digital systems, like computers, represent information using binary digits, ones and zeros. The term ‘binary’ refers to the use of only two values such as two digits or two states: on/off. Computer screens display images as grids of pixels, which are tiny, coloured squares. Exploring binary numbers through pixel-based image creation helps students understand the purpose and functionality of binary. With a single binary digit (one bit ), we can only represent two values. So, using one bit to represent a pixel's colour means each pixel can only have one of two possible colours. There are efficient ways of encoding an image in binary, such as run-length encoding.

Creativity with automated pixel art

What is this about?

Pixel art is a digital art form that uses small, distinct pixels arranged in a grid-like pattern to create images. Each pixel can be assigned 1 bit to represent an image in binary, for example, in black and white in binary with black = 0 and white = 1. As an extension, students can explore greyscale that uses 2 bits to represent an image allowing for four colour values.

Algorithms can be used to generate patterns by repeating specific instructions involving binary. For example, use iteration to repeat a set of instructions that turn pixels on or off in a specific pattern.

A spreadsheet can be used to automate design of pixel art. As an alternative, instead of using binary, students could use whole numbers to represent colours in their spreadsheet, for example, red = 1, blue = 2, yellow = 3.

Data types and operations

What is it about?

In digital systems, data types define how information is represented internally and the operations that can be performed on it. Numbers are a data type. We can use operators such as (+) for addition, (-) for subtraction, (*) for multiplication and (/) for division.

A string is another common data type used to represent a sequence of characters that can contain letters, numbers, symbols and spaces. Strings can be joined together (concatenation), merging them into a single string. Programming can be used to illustrate the concepts of data representation and the impact of data types on operations.

Algorithms

What is this about?

Following and designing algorithms with branching and repetition draws on students’ problem-solving skills. They break down complex tasks, identify patterns and create efficient solutions using If/then statements and loops to improve efficiencies. Students analyse problems, consider possibilities and design suitable solutions as an algorithm first. An algorithm can be written as a series of steps or diagrammatically such as in a flowchart. The algorithm can then be implemented as a computer program.

Branching and iteration

What is this about?

The sequence and flow of a program is determined by control structures such as branching or iteration (repetition). In a program, ‘if’ statements are branching control structures that allow for decisions that enable the user to choose different paths. Loops are iteration control structures that repeat instructions. These concepts are fundamental in programming across languages. Learning them in Scratch develops transferable skills for exploring new tools and languages. This unit predominantly uses Scratch; however teachers may substitute a similar visual programming language.

Content description

Implement algorithms as visual programs involving control structures, variables and input AC9TDI6P05

This sequence enables students to:

identify and explain what repeat blocks do in a program
create a program that uses a repeat command
explain ways to provide decisions that enable the user to choose more than two different paths
create a program that includes decisions that enable the user to choose more than two different paths.

Supplementary information

In Scratch, students learn if/then statements to control program flow. They use comparison operators (e.g. =, <, >). For example, ‘if light level < 100, turn the light on’. As their skills develop, introduce if/else statements for multiple decisions and alternative paths when conditions aren't met. To appreciate efficiency and convenience, students learn loops – a form of iteration. Teach conditional loops like ‘repeat until’, which execute once before checking the condition. For example, in game play, ‘repeat until lives = 0’.

Introducing variables

What is it about?

Variables allow students to store and manipulate data within a computer program such as in a Scratch project. A variable can be used to represent different types of information, such as numbers or text, and store these values that change during program execution. They can update variables based on user input, events or calculations, which can affect the behaviour and appearance of sprites (on screen characters or objects).

Unit sequence

This topic offers 3 pathways

Core Unit

User-focused design process

What is this about?

Students are introduced to the design process (empathise, define, ideate, prototype and test). This process begins with empathising with the users and identifying their needs. It involves creating user stories to inform design considerations. In the define phase, the problem or challenge is defined, identifying goals and any constraints that need to be address in the design. In the ideate phase, various solutions are generated through brainstorming. Next a prototype is developed which can be paper-based or simple digital mock ups. The test phase involves getting feedback from the user to gain insights on usability and effectiveness in meeting the design criteria.

Once students have developed familiarity and confidence with the design process and the use of user stories, they can be presented with a specific problem or challenge that requires designing a digital solution. These are presented as options in the three pathways for this unit.

Supplementary information

Input devices allow us to enter raw data into a computer. A digital system, such as a tablet or desktop computer, processes the data. It then produces outputs that are communicated using an output device. Input devices can be manual or automatic. Data such as text, images, sound and numbers are input into a digital system using a range of digital devices. The output is communicated using different components; for example, a speaker for sound. To enable data input, specific software may be required; for example, to gain audio and video input from a webcam, the digital system requires suitable software. This software is also used to output the webcam data to a screen. Users of digital systems need to have the ability to enter data into computers. Various peripheral devices have been created to fulfil this need and this process of invention continues.

The Makey Makey board will plug directly into the computer’s USB peripheral port and essentially behave like an input device. When specific keys are pressed the Makey Makey board can mimic those keystrokes. Students can explore and use different materials to test ways to provide an input that has a functional benefit for their user. For example, users with limited fine-motor control may benefit from a design that has larger, easier controls to use keyboard strokes – such as up, down, left and right arrows – to interact with a game. Makey Makey is an invention kit available for purchase that allows you to interact with a computer, using everyday objects as a replacement for inputs such as a keyboard or computer mouse. Activating a key means creating a closed circuit. For the circuit to work, electrons have to be able to flow from the Makey Makey input key to Makey Makey’s ground pin. So materials chosen as the input must conduct some level of electrical energy. This includes aluminium foil, a banana and even a circuit drawn in grey lead pencil.

Design a community space in 3D

What is it about?

Designing, building and exploring virtual worlds that resemble the real world allows students to apply coding skills in a practical context. They can build structures, automate tasks and create contraptions drawing on, and developing, programming skills. Minecraft enables students to engage in an immersive virtual 3D environment and allows them to see the immediate results of their code. They can quickly iterate, test different approaches, and observe how changes affect their virtual world. This feedback loop promotes a hands-on learning experience and helps students grasp coding concepts. Using the context of designing a community space (which can incorporate green city or green building design), students define the problem, identifying user needs. They create user stories based on user needs. They create and test their digital solution against the user stories and design criteria.

Design an automated solution

What is it about?

Designing an automated solution enables students to apply their programming knowledge and skills to solve a problem or challenge. When designing a solution, students consider the design criteria and needs of the user to ensure it meets the requirements. They design an algorithm as a series of steps with decisions and iteration. They select a technology type or application best suited to implement the algorithm which they are familiar with and to which they have access.

Students may choose:

to create a computer program such as Scratch to automate tasks involving interconnected devices, for example, a virtual assistant to control smart devices, such as in-home automation
to program a robot to perform automated tasks; this may involve writing code to plan a pathway and navigate its environment, or more complex programming to control motors, sensors and other components of the robot
to use a micro-controller such as a micro:bit, the solution may incorporate sensors to sense their environment to automate a task.

use if/then statements to compare a variable to a value
create computer programs that use inputs and outputs on a controllable device.

Supplementary information

The technology type chosen for this unit will depend on resources available and students’ familiarity with the technology. Suggested lessons often focus on a particular technology type. It may be possible to apply the approach to a similar application focusing on the key concepts being presented and substitute a technology to which students have access.

A sensor is a device that senses and reacts to some type of input from the physical environment. Types of input include heat, light, moisture, motion, pressure or any other environmental phenomenon. The result is typically a signal that is either translated to a human-readable display at the sensor location or sent electronically over a network for reading or further processing.
