Basic 9 Computing Term 1 Week 9 Lesson Plan

Begin with a simple demonstration. In a dim room, turn on a bright lamp positioned directly in front of the computer screen, creating glare. Ask learners to observe and describe how comfortable it feels looking at the screen. This will provide a tactile understanding of bad lighting practices. Share performance indicators and introduce the lesson.

Learners compare the Computer monitor under side lighting, direct glare and comfortable ambient lighting without staring at a bright screen. They reposition the Desk lamp so it lights the work area without reflecting into the eyes or screen. Groups use the Printed glare-safe workstation chart to evaluate each arrangement and record the safest monitor, window and lamp positions. They explain how good lighting, screen breaks and correct positioning reduce eye strain and headaches.

Use peer discussion and effective questioning to find out from learners what they have learnt during the lesson.

Begin with a real-world scenario: "Think about a time when you felt your computer or another electronic device was getting too hot. What did you do about it? Share your experiences." Encourage learners to discuss their encounters with hot electronic devices.

With all equipment switched off, learners inspect the ventilation openings on the Desktop system unit and explain why they must remain clear. They position the Small desk fan to model air movement without blowing dust directly into the unit. Groups use the Printed workstation heat-risk chart to identify blocked vents, overloaded sockets and unsafe placement near heat or water. They propose and demonstrate safe controls for heat build-up and electrical risk.

Take feedback from learners and summarize the lesson.
