Lesson Plan

• Describe the function of common output devices (display, printer, audio, tactile, storage).
• Explain how output devices convert digital data into visual, auditory, or tactile forms.
• Compare the advantages and typical uses of different output devices.
• Evaluate factors for selecting the most appropriate output device for a given task.

• Computer with internet access and projector
• Printed handouts of the device comparison table
• Sample output devices (e.g., printer, headphones, Braille display demo)
• Scenario and device‑card worksheets
• Whiteboard and markers

Begin with a quick question: “How do you know when a computer has finished its work?” Connect this to students’ prior knowledge of input devices. Explain that today they will explore how computers communicate results to us. Success will be measured by their ability to identify device types, state purposes, and justify selections.

1. Do‑now (5') – Mini‑quiz on input devices to activate prior knowledge.
2. Mini‑lecture (10') – Definition of output devices, overview of types and purposes.
3. Guided activity (15') – In groups, examine device cards and complete the comparison table.
4. Class discussion (10') – Groups share findings; teacher highlights key purposes and real‑world examples.
5. Decision‑making task (10') – Scenario cards require students to choose the most suitable output device and justify using selection criteria.
6. Exit ticket (5') – Write one purpose of an output device not mentioned in class.

Summarise the main functions and selection factors for output devices. Collect exit tickets to check understanding, and assign a brief homework: research an emerging output device (e.g., AR glasses) and write a paragraph describing its purpose and potential use.
