Autobiography of a Blackboard
I spend most of my life hanging on a wall in a classroom. I have been an integral learning tool for many decades since the dawn of modern civilization. I feel quite content for having contributed in making the mankind better. A classroom without me would be as dull as a garden without flowers. Teachers impart knowledge to students through me. I help them simplify the abstruse concepts of knowledge. Like all other things I have been evolving into better versions. Earlier I used to be any plain hard surface painted black. Then I began to be made out of wood also. As the time advanced I was made out of a special glass. The glass version was quite convenient as cleaning it was quite easy and not much of the chalk remained stuck to my surface. Then people experimented with my colour also. My green board version seems to have become quite popular at schools. Then I evolved into whiteboard gradually. In place of chalks, colourful markers are used which though a bit more expensive, don’t cause chalk dust problems.
My most advanced and recent version is white-interactive smart board. A projector attached to a computer projects all the learning data onto my surface thus making classroom learning more efficient, colourful, interactive, engrossing, and effective. Children prefer my smart board version to all other versions. Though I have evolved over the years, however, my prime purpose of spreading the light of knowledge remains to be unchanged.
