Exhibitions (How they can change the world and what is in reality happening)

My first question  to you is that how you have encountered an exhibition ? Mostly any school exhibition. You think over it. Before I deliver my opinion let's know the real meaning of exhibition provided by wikipedia :-

      An exhibition, in the most general sense, is an organised presentation and display of a selection of items. In practice, exhibitions usually occur within a cultural or educational setting such as a museum, art gallery, park, library, exhibition hall, or World's fairs. Exhibitions can include many things such as art in both major museums and smaller galleries, interpretive exhibitions, natural history museums and history museums, and also varieties such as more commercially focused exhibitions and trade fairs.

     So this is what an exhibition is. But what do you think it should be, as you know nowadays in school what is happening, in exhibition students use to just copy the models or projects from somewhere and represent it by mugging up the script (not talking about each and every schools and institutions but mostly are doing the same), but this isn't the correct way to organize an exhibition. 

          Actually exhibition should be the way or opportunity for an student to represent or propose his/her idea or solution to resolve the real life problems (and to advance and modernize the living of beings without having any damage to our environment) by using the knowledge and skills which he/she is learning from the schools/institutions. And in many places real exhibitions are being held.(we appreciate that) 

         In exhibitions students should use their ultra skills to give an initiative to change(improve) the world. You may give your opinion where am going wrong and what other super things can be done and what initiatives, we as an individual can take to overcome over this issue.
