What does our school network look like?

In this lesson, learners will further develop their understanding of computer networks. They will see examples of network infrastructure in a real-world setting and relate them to the activities in the last lesson.

Summarised lesson plan

In this 45-minute lesson, the teacher introduces the learning objective and success criteria (Slides 1-6), reviews network components, and discusses the benefits of computer networks (Slide 7). The class then goes on a school tour to identify key network components (Slide 8) and maps the school network (Slide 9). In the Plenary, learners recap network concepts and discuss benefits (Slides 10-11). The lesson concludes with assessment and summary slides (Slides 12-13), covering essential aspects of computer networks and their role in school environments.

Subject Knowledge 🤓

1. Computer Networks: A computer network is a system of interconnected devices (computers, printers, switches, etc.) that can communicate and share resources. Think of it as a digital web that allows devices to interact and exchange information.
2. Network Components: Understand the main components of a network, including devices like computers and printers, switches (devices that enable devices to connect and communicate within a local network), servers (computers that provide services or resources to other devices), and network cables (wires used to connect devices together).
3. Data Flow: Comprehend how data and information move within a network. Explain the process, such as when a computer sends a request for a file, and how it travels through network cables and devices to reach its destination.
4. Practical Benefits: In the context of a school, emphasise the practical advantages of computer networks. These include the ability to easily share files, access shared resources (like registers and administrative systems), and enhance communication between staff members and students.
5. Network Hardware: Have a basic understanding of network hardware, including routers (devices that connect networks and enable internet access) and wireless access points (WAPs, which provide wireless connectivity). This knowledge will help you explain how networks are set up.
6. Network Mapping: Explain the concept of creating a network map or diagram to visually represent how devices and components are connected. This helps students understand the physical layout of the network.
7. Internet Connection: Clarify how the school network connects to the internet through a router. This is crucial to address any student questions or mentions of the internet during the lesson.
