Overhead Projector 

Overhead  projector  casts an images of the transparencies  on a  screen. Transparencies  are frequently  used  visual  aids  especially  when  audience is large. With sketch  pens or color  pencils matter  can be  written  on them. The better  way is  to write  in block  letter or draw  graphs  etc, in computer  and have  their  print ( either  through photo state machine  or laser printing ) on transparencies.

Transparencies  are  a effective  means  of projecting  graph charts  or data  on the  scene  which  are visible to the  large  audience. Presented matter  can be  erased and  transparencies can be  reused  for new  presentations  or they  can be stored  for further  use.

 To make it more  effective:

a.Pay  attention to the  focusing.

b.Show  transparencies only when they  are discussed.

c.Use paper  or cardboards to cover the parts  yet to be  discussed.

d.Face  the audience as  you  speak.
