February 23, 2010 – 00:00

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.
• The display should be set as high as possible and ensuring that it is not near any viewer.
• It is recommended that the angle between the viewer's eye and perpendicular to the screen is less than 40 º.

Advantages of Overhead
• Easy to operate
• an image is enlarged,clear and sharp.
• Explanation to a number of viewers.
• It is not necessary to darken the place.
• The facilitator is always front wing audience.
• Allows images.
• Projecting animated figures or models.
• ordered sequences can be illustrated.
Disadvantages of the Overhead
• Immobilize the teacher and makes it even more dependent on the
• There is a risk that the small size of the letters and make them indecipherable signs.
• Use plenty of light can cause fatigue in the teacher and the public.
• Students put all their attention to copy the contents of the overhead projector and stop paying interest to the explanations of the teacher.

I have reached the conclusion that the projection system has been a great help in presentations of facilitator,through the object to be submitted,you will create an image much larger than the original size of it,and gained much public attention.This work can be more interactive and fun and to further develop student creativity.


There are different types of poster paper can be either used to give away light information to the public about an event or idea or activity is appropriate usually put wing public view without attacking the society to be seen by her .Since it covers a clear and accurate information.
It is designed to attract attention.
The colors should harmonize.

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.
The professors are slow to change and are still using overhead projectors instead of using computer generated information on the wall. However, there is a breakthrough, and this is the word "paperless

      Another option is to enlarge the image you have using the grid system. Draw grid lines in the original …transfer the image, drawing the shapes in each square. For example a 1/2 inch square on the orignal, would be a 6 inch square on the wall. That's the way a professional muralist would do it. That's the way I would do it.
