Year 4 Technologies
A comprehensive Year 4 technology course that bridges the gap between physical hardware and digital creation. Students progress from understanding data representation and network structures to designing complex visual programs and evaluating the social impact of automation.
01The Language of Computers
Students explore how digital systems use symbols and binary to represent data such as text and images.
Students investigate how computers use on and off states (binary) to represent simple numbers and information.
Students learn how binary codes are used to represent letters and simple words, exploring ASCII concepts.
Students understand how pixels and grids are used to store and display visual information, focusing on monochrome images.
Students explore how different combinations of binary data can represent various colors in digital images.
Students collect simple data sets from their classroom environment and organize them into tables or lists.
Students learn to represent organized data using simple charts and graphs to identify trends.
Students manipulate data sets to identify trends and draw conclusions about classroom problems or questions.
Students use analyzed data to make informed decisions and propose solutions to simple problems.
02Connected Worlds
An exploration of how digital systems connect and the hardware components that make communication possible.
Students identify the main internal components of a computer (CPU, memory, storage) and their basic functions.
Students differentiate between various input and output devices and their specific uses.
Students explore different types of storage devices (USB, hard drive, cloud) and when to use each.
Students map how information travels between devices within a local network, like a classroom or home.
Students learn about the internet as a global network and how information travels across it.
Students develop strategies for creating strong passwords and managing online accounts securely.
Students understand what a digital footprint is and how their online actions create one.
Students learn to identify cyberbullying and strategies for responding to and preventing it.
03Logic and Sequences
Building the foundations of computational thinking through offline and online algorithmic puzzles.
Students identify and create precise sequences of instructions for everyday physical tasks, like making a sandwich.
Students practice identifying and correcting errors in sequences of instructions for physical tasks.
Students use 'if-then' logic to create simple programs or scenarios that respond to different conditions.
Students learn about loops to repeat actions efficiently in algorithms and block-based programming.
Students explore a visual programming environment (e.g., Scratch) and its basic features.
Students translate simple algorithms into block-based code to create basic animations and movement.
Students use event blocks to make their visual programs interactive, responding to user input.
Students practice identifying and fixing errors (bugs) in their block-based programs.
04The Design Process
Applying design thinking to identify user needs and create digital prototypes for real-world problems.
Students use empathy and observation techniques to understand the needs and challenges of potential users.
Students define a clear problem statement based on user needs and brainstorm diverse solutions.
Students translate brainstormed ideas into initial sketches or wireframes for digital solutions.
Students create interactive paper prototypes to simulate user interaction with a digital solution.
Students use simple digital tools (e.g., drawing software, basic presentation slides) to create digital mock-ups.
Students conduct simple user tests with their prototypes and collect constructive feedback.
Students analyze feedback and iterate on their designs, making improvements based on user input.
Students present their final prototype and explain their design process and rationale.
05Digital Citizenship and Society
Analyzing the impact of technology on daily life and developing ethical habits for digital participation.
Students investigate how local businesses use technology to improve efficiency and reach customers.
Students explore how technology is used in schools and for learning outside the classroom.
Students discuss the concept of automation and its effects on jobs and daily life.
Students learn about copyright and Creative Commons licenses for digital content.
Students practice crediting digital sources for images, text, and other media used in their projects.
Students reflect on their own digital footprint and its impact on their online reputation.
Students reflect on their personal screen time habits and their effects on physical and mental health.
Students apply principles of digital citizenship to real-world scenarios, promoting positive online behavior.
06The Grand Challenge
A capstone project where students apply all their skills to solve a specific community or environmental problem.
Students conduct in-depth research into their chosen problem, gathering data and understanding constraints.
Teams brainstorm a wide range of potential digital or hybrid solutions for their identified problem.
Students plan the sequence of actions (algorithms) and the visual layout (user interface) for their digital solution.
Teams begin coding and building their digital solution using block-based programming or other tools.
Students incorporate interactive elements like buttons, sliders, or simple sensors (if available) to enhance their digital solution.
Teams rigorously test their solution, identify bugs, and refine their code and design.
Students prepare their presentation, demonstration, and supporting materials for the final showcase.
Teams present their final solutions to an audience, demonstrating functionality and explaining their journey.
