Active learning ideas

Input and Output Devices

Active learning works for this topic because students need to physically experience how information moves between devices to grasp the abstract concept of networks. Moving as a data packet or touching cables provides a concrete foundation before introducing abstract ideas like protocols and signals.

Simulation Game: The Human Internet

Students act as 'nodes' in a network. They must pass a 'packet' (a piece of a message) from one side of the room to the other, following specific rules (protocols) and dealing with 'broken' connections (blocked paths).

Differentiate between an input device and an output device.

Facilitation Tip

During the Human Internet, assign each student a role like 'sender', 'receiver', or 'router' to ensure active participation and clear data flow demonstration.

What to look for

Present students with images of 5-6 different devices (e.g., microphone, speaker, printer, touchscreen, webcam, headphones). Ask them to write 'Input' or 'Output' next to each device on a worksheet. Review answers as a class, asking students to justify their choices.

Activity 02

• Gallery Walk
• 20 min · Individual

Gallery Walk: Undersea Cables

Display maps of the global undersea fiber-optic cable network. Students explore the maps to find how Australia connects to Asia and North America, noting the specific coastal cities where cables land.

Design a system using specific input/output devices for a task.

Facilitation Tip

Set a 3-minute timer for the Gallery Walk so students focus on observing undersea cable photos and notetaking rather than casual browsing.

What to look for

Give each student a card with a simple task (e.g., 'Listen to music', 'Type a story', 'See a picture'). Ask them to list one input device and one output device needed for that task and briefly explain why.

Activity 03

• Think-Pair-Share
• 15 min · Pairs

Think-Pair-Share: Wired vs. Wireless

Students brainstorm the pros and cons of using a cable versus Wi-Fi. They pair up to decide which connection is better for a gaming console versus a mobile phone and share their reasoning with the class.

Evaluate the best input device for a person with limited mobility.

Facilitation Tip

For Think-Pair-Share, provide sentence starters like 'I chose wired because...' to scaffold student comparisons between connection types.

What to look for

Pose the scenario: 'Imagine you are designing a computer for someone who can only use their eyes and cannot use their hands. What input device would you choose and why? What output device would be most important?' Facilitate a class discussion comparing student choices.

A few notes on teaching this unit

Teach this topic by moving from concrete to abstract: start with devices students can touch, then connect those to the idea of signals and networks. Avoid overwhelming students with technical terms like 'protocols' until they understand the basic flow of input to processing to output. Research shows that hands-on simulations reduce misconceptions about how data travels, so prioritize movement and physical models over lectures.

Successful learning looks like students identifying input and output devices with confidence and explaining how data travels between them. They should describe networks as connected systems with clear physical components rather than vague technology concepts. Misconceptions about invisible signals or magic systems should be replaced with accurate vocabulary and examples.

Watch Out for These Misconceptions

• During the Human Internet, watch for students who describe data traveling as a single whole file.

  Use the simulation to break messages into parts by having students write each word on a separate slip of paper, then pass them individually through the network to show reassembly at the end.

• During the Gallery Walk: Undersea Cables, watch for students who describe the internet as 'invisible' or 'in the air'.

  Direct students to examine photos of server farms and undersea cables, then ask them to trace a path from their device to another continent using these photos as evidence.
