Overhead Projector (OPH)
Advantages of the Overhead Projector

The stage of the projector is large(10 by 10 inches). His works appears immediately on the screen.
It is easy for teachers and students to create their own materials for the use of the overhead projector.
An increasing number of high quality commercial transparencies.
Overhead Projection Techniques
You can show pictures and diagrams
You can use felt pen or wax-based pencil to ass details.
Control the rate of presenting information.
Superimpose additional transparency sheets as overlays.
Show three dimensional objects from he stage of the projector.
Move overlays back and forth across the base.
Simulate motion parts of a transparency by using polarized light.
Simultaneously project on an adjacent screen other visual materials.
Other reminders of effective use of OHP:
Stand off to one side of the OHP while face the students.
Don't talk to the screen.
Place the OHP to your right,if your right handed and to your left,if you are left handed.
