Blackboard- a unique inventionBefore the invention of blackboard the students would use their individual slates for study and teacher would teach all his students one by one with the help of their individual slates.
In 1801, James Pillans of Scotland, found a solution of this problem by inventing the first blackboard when he hung a large piece of slate on the classroom wall. It was proved as the first revolutionary step in the field of education which caused a big change in the method of teaching.
The scholars appreciated the inventor of the blackboard in these words "the inventor or introducer of the system deserves to be ranked among the best contributors to learning and science, if not among the greatest benefactors of mankind"
I think it was the greatest invention of modern age which helped to mould the common and ordinary students into genius and great scientists who benefited the world by their inventions and discoveries,
Over the time, the color was changed from black to green or white, nevertheless, it's still called 'blackboard', the screen on which the images of nation builders of the next generation are reflected.
