Use of Overhead Projector (OHP):
Overhead projector is a device that can project a chart, a diagram, a map, a table or for that matter, anything written on transparent plates, upon a screen on the white wall before students in a class. This makes teaching illuminative, illustrative and impressive. It also saves a great deal of the teacher’s time used in drawing or writing. These transparencies can also be preserved by the teacher for future display while facing up the same topic. It is very simple to prepare such transparencies. All that a teacher has to do is to draw or write, as the case may be, upon transparent plates with any dark ink with a fibre tipped pen. Any material meant for display before the class while teaching can also be typed on such transparencies using a good carbon paper. In case transparencies are to be washed out for use, washable water colour can also be used for writing on the transparencies.
