How should the paper presentation ideas be?

Nowadays in colleges and universities technical festivals and competitions have become common. Students are very much interested in attending those festivals and presenting their scientific ideas. But most of them are not guided and motivated enough to do some useful scientific work. Most of the students derive their paper presentation ideas either from information resources like internet, books of from some previous works. There is hardly any novelty or innovation in their work. This will not help them to get scientific exposure and motivation. So institutions and teachers should properly guide them to conceive their paper presentation ideas. Then only the ultimate aim of conducting the technical festivals and competitions will be fulfilled.
