Whenever I assign research papers I expecte a little cheating and inadvertent plagiarism, but the following case is particularly interesting. Now to fully appreciate this you must understand that I am teaching in a high school in St. Louis, MO, U.S.A.
A student was writing about the use of new technology in the game of football. I was suspicous that he hadn't written parts of it but was willing to give him the benefit of the doubt until I came across this sentence: "People feel as though they are playing the same game as the blokes they see on the TV."
The student didn't even know that the paper he had copied was about soccer and not American football as he had intended. The truly damning evidence however comes when I confronted the student and he adamantly denied that he had cheated even after I showed him and the rest of the class the page on the SmartBoard.
