Teacher's Corner 1.3

1. Begin the lesson by asking , “what makes the computer work?” lead them to discovering that it needs to be plugged in.Ask them to think of other things that need power, e.g., TV. Ask if they know the dangers associated with power cords and power outlets. Summarise the safety issues.Emphasize that the teacher must be asked every time the computer is to be turned on

or off.

2. Ask, “What if they banged the keyboard?” “What will happen if they pull the mouse?”. Summarise that the computer is a delicate machine.

3. Ask them as to what would happen if water or food gets spilled near the computer. You may get a variety of responses ranging from “Mommy will shout” to “There will be a bomb blast”! Clarify their myths and inform them as to why they should not eat or drink near the computer.

4. Ask questions like, “what would happen if they put their head very close to monitor?” “How long should they work at the computer?” Show students the proper way to position the neck when viewing the monitor or demonstrate with a student. You can summarize their responses and finally give the following guidelines:

a) Keep your eyes at least at an arms distance from the monitor.

b) Keep your neck straight so that you are not looking up or

down at the monitor.

c) After 10 min. of using the computer, move your eyes and neck,

d)Stretch your hands and fingers if you are using the keyboard or mouse.

Demonstrate the proper way to position wrist when using the keyboard and mouse.

5. Talk about how loud sounds can damage our ears. Tell them to keep the loudness of

speakers at a comfortable level. Lead a discussion on appropriate team behaviour –

sharing, giving space, taking turns, not crowding, pushing, pulling, etc. Tell them to take

turns when using keyboard or mouse. You can ask them, “What would happen if nobody

wants to share the computer at school? Will everybody be able to learn? Will they enjoy

using comptuers as much without their friends?”
