Digital systems and peripherals

What is this about?

A desktop computer is an example of a digital system. A peripheral is typically external to a desktop computer and connected either via a wireless network or a cable. A digital system, such as a tablet, often has internal hardware components such as a camera, microphone and keyboard; however, on other digital systems these components might be considered peripherals because they need to be added to the digital system. Students may use tablets that perform multiple tasks such as recording video via internal camera and microphone, images with camera and entering text using a screen keyboard. Laptops may also have an in-built camera.

Using digital systems safely

What is this about?

Technologies are an embedded part of our lives, and it is essential that students understand how to engage responsibly in online spaces. Using the school's (Digital Literacies/ICT) agreement as a focus, develop an agreed set of rules and discuss protocols for digital technologies use. It is important students understand what it means to behave safely online and have an opportunity to explore this in more detail. Discuss the use of personal information or images when communicating online. Empower students with the knowledge of how to act responsibly online and equip them with the tools to know how to deal with cyberbullying behaviour. Use a collaborative online project to apply protocols and manage a task.

Collaborate and share content

What is this about?

Introduce ways to collaborate and share content using a supported and guided approach. Choose a focus to collaborate such as brainstorming ideas on a class topic, completing an online quiz in real time or creating a presentation collaboratively. When students collaborate as a team they will require a shared space such as a place for an online document to enable group members to contribute and have access to the most up-to-date version. Depending on your school, common platforms that enable online collaboration include Google Workspace for Education, Microsoft 365 or Apple products such as Keynote. As students use these types of platforms, they follow agreed protocols related to digital etiquette, privacy and safety.

Algorithms

What is this about?

Algorithms are step-by-step instructions for solving a problem or performing a task. In Digital Technologies exploring algorithms is a way to establish the guiding logic for computer programs. An algorithm can describe a sequence of steps and decisions. Sequencing refers to placing the steps to be performed in order, one after another. Branching involves making decisions resulting in following different paths based on specific conditions. An example is in a multiple-choice quiz – the user selects the correct answer and gets positive feedback and moves to next question, else the user gets feedback to try again!

Programming a sequence

What is this about?

At the beginner level of programming, use a visual programming environment like Scratch, Microsoft MakeCode or code.org’s programming challenges to learn the basics of programming. Students can turn basic algorithms into a working computer program. They arrange blocks to execute steps in a specific order. They can create a basic program where the sprite (character) responds to events, moves in different directions, based on user input. User input involves information from the person using the program, often obtained through keyboard or mouse actions. For instance, the program can ask for the user's name with the question 'What's your name?' and then use that input in the program. As they grasp the basics and familiarise themselves with the range of visual blocks, students can move on to creating more advanced programs.

Branching and iteration

What is this about?

Once students have a basic understanding of the fundamentals of programming, they can progress to more advanced programming concepts. This includes exploring branching, where decisions direct the program's flow, and repetition loops, which enable the execution of specific actions iteratively. These elements give students the tools to create more intricate and sophisticated programs.

Branching that result from a comparison

What is this about?

As students develop their programming skills they can create more complex programs. At certain steps in the sequence students may want an input to make a decision. To get a true or false answer, branching decisions may result from a comparison. The operator may be: < (less than), > (greater than) or = (equal to).

Who are you designing for?

What is this about?

An important part of the design process is to consider the user, who they are and what they need. We can use what we call a ‘user story’ to help define the purpose and the user experience. For example, a user story might say, ‘As a player, I want to control a character with arrow keys to navigate through a game and collect stars for points’ or ‘As a reader, I want a way to read that is fun so that I can overcome my difficulty in keeping interest’. When designing a digital solution, the user story informs the development of the algorithm that we use to implement as a computer program.

Programming a digital solution

What is this about?

As students develop their understanding of user stories they can use them when designing their algorithms which they then implement as a visual program. As user stories is a relatively new inclusion in the curriculum it may need to be explicitly connected when designing algorithms and programming solutions. Prompting students to think about who the user might be, what they want and their reasons why that need is important, can help students in the design phase. Students create their program exploring branching, where decisions direct the program's flow, and repetition loops, which enable the execution of specific actions iteratively. They then evaluate their program based on the user needs to see how well it met their needs.

Exploring types of data

What is this about?

Exploring how text, numbers, sound and images are transmitted between digital systems. Students explore ways data can be transmitted between digital systems; for example, text (such as a blog post), numeric (for example, survey results), sound (for example, audio recordings) and images (photo and video). This understanding lays the groundwork for more advanced concepts, such as the way data is represented using binary – a system that uses only zeros and ones. It is a fundamental concept of data representation. The Mathematics learning area can be integrated with Digital Technologies to make learning more meaningful by combining data acquisition (statistics) and types of data (data representation).

Data detectives: symbols

What is this about?

Using established conventions for representing data helps create a common understanding, allowing individuals from diverse backgrounds to interpret and act upon visual information efficiently. When representing data using symbols and images, students can explore these conventions and apply their understanding of ways to represent the same data in different ways. Flags, maps and public systems such as transport provide a useful context to explore data representation and representing data for a purpose. Braille, a system designed for people who are blind or have visual impairment, enables reading through raised dots that represent letters, numbers and symbols. QR codes are another way to represent weblinks.
