The projector is designed so that the teacher can give his explanation without having to give back to their listeners.So eloquent make learning more and more attractive to the learner,can view the contents of your information on it and make accusations overhead right there without having to flip back.Its function is overhead educator explanations reinforce and encourage student participation and increase student-teacher interaction,teacher-student
Those materials are plastic,glass,and acetate.Among them are:
• Transparencies
• Instruments and equipment drawings as rulers,squares.
• opaque materials,such as part of an engine,seeds,leaves.
Overhead in the classroom and use
In the classroom there are difficulties but we must get the best conditions for the projection of the material.
• The Overhead should be placed as far as possible from direct sunlight.
• The projection can be done in ambient light conditions.
• The Overhead will be the darkest area of ​​the room ..
• Spectators should be in the correct viewing zone.
• The head should not interfere with visibility.
• The overhead projector is on the desk,or as close to it.
• The apparatus of the screen to provide a satisfactory image size.
• The size and height of the screen should be convenient.

Because the professors are stuck in their ways

The college professors are tenured and they are stuck in their ways, so they do not like change at all. They teach that the student must be open to change and reinvention of careers and knowledge, however, they still, like clockwork, buy the U.S.A. today newspaper and spread it out all over the toilet stall while they read the articles out loud pronouncing with care each syllable with gutteral accuracy and acumen.
