                                For the Teacher
Safety
   • Ask students “what makes the computer run?” If they answer that it needs
       to be plugged in, you can proceed to the next step. If not, ask them to think
       of other things that need power to run, e.g., TVs.
   • Ask if the students know what dangers are associated with power cords and
       power outlets.
   • Inform them that they should not eat or drink near the computer.
Health
  • Show students the proper way to position the neck when viewing the monitor.
       Or demonstrate with a student. You can give them the following guidelines:
             •  Keep your eyes at least a foot from the monitor.
             •  Make sure you are not looking up or down at the monitor. Keep
                your neck as straight as possible.
             •  After 10 min. of using the computer, move your eyes and neck.
                Stretch your hands and fingers if you are using the keyboard or
                mouse.
  • Show students the proper way to position wrist when using the keyboard and
       mouse.
  • Talk about how loud sounds can damage our ears. Tell them to keep the
       loudness of the speakers at a comfortable level.
  • Show students simple eye and neck rotations and stretching.
Social
   • 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.
Technical
   • Emphasize that the teacher must be told every time the computer is to be
      turned on or off. Depending upon their understanding, you may discuss with
      them why the icons are arranged as they are – so it is convenient for everyone
      to use. Ask them what would happen if they moved it – make it disappear into
      the trash.
We recommend making a poster with the dos and don’ts and putting it up in a
prominent place near the computers.
