The act of plagiarism is to copy more or less some one's else's ideas, thoughts, opinion and creations and introduces them as his own. I was studying in 12 grade, i had an experience of observing such kind of plagiarism. One of my classmates was accused of plagiarism by one general histry teacher. We were told to write an article on "oppression of British Government to farmers for blue plantation. My classmate was inattentive to her studies. At the end of the last moment, she went to a senior student and picked up her last year's assignment on the same topic. She added a large portion of that assignment to her writing and submitted to her teacher. The teacher could catch her act of plagiarism and expelled her for that semister.
A man is not perfect and knowledgeable in all respects. As a human being i have some limetations. In writing the latest problem analysis essay, i had not enough experience and enough instance before me. To find out the reasons of plagiarizing were little bit difficult for me. I had another problem what way and how i observe the situation.
To my opinion, the important issue in regard to plagiarism to figure out the assignment is really the student's creations or some one else's.
