MAXIMIZING THE USE OF THE OVERHEAD PROJECTOR AND THE CHALKBOARD

Chalkboard is needed in the field of education in away that it is use by our teachers in order to emphasize the important topic in every timer they discuss cause in the way of writing that can be seen by everyone is one of a 

way in emphasizing important things.A blackboard or chalkboard is a reusable writing surface on which text or drawings are made with sticks of calcium sulfate, known, when used for this purpose, as chalk. Chalkboards were originally made of smooth, thin sheets of black or dark grey slate stone. Modern versions are often green or brown and are thus sometimes called a green board or brownboard instead.

Using technology in today's classroom is a given. Far gone are the days when slide-show presentations with attention-grabbing graphics are the classroom's technological zenith. We live in the age where blogs, chat rooms and podcasts are common teaching tools. Yet, a classroom can still thrive when stripped down to the basics---chalk and a chalkboard. Using chalkboards in teaching improves teaching effectiveness, classroom management and student academic success.

But being a teacher someday we must think of the important things needed in using the chalkboard cause as usual the same with other things there are also techniques on how to use certain thing in proper way we must see to it that every time we write on the board you must not display your back portion,you must maintain your eye contact to your students.

An overhead projector is a variant of slide projector that is used to display images to an audience.An overhead projector typically consists of a large box containing a very bright lamp and a fan to cool it. On top of the box is a large Fresnel lens that collimates the light. Above the box, typically on a long arm, is a mirror and lens that focuses and redirects the light forward instead of up.

An overhead projector is a very basic but reliable form of projector. The overhead projector displays images onto a screen or wall. It consists of a large box containing a cooling fan and an extremely bright light, with a long arm extended above it. At the end of the arm is a mirror that catches and redirects the light towards the screen.

An overhead projector can be used to enlarge images onto the screen or wall for audiences to view. Transparencies can be placed onto the projector to be viewed by both the audience and the speaker. The overhead projector was once a common feature in both classrooms and business meetings. Recently, it has seen a decline in use, as more sophisticated computer based projectors are favored.

It is very useful in order for our students to see the real beauty of a certain picture in a bigger one.
