I am not so concerned about plagiarism in the sense of copying like Wayne's son did when he copied a Canadian assignment in a New Zealand context and tweaked it appropriately (I call that learning transfer when I do it myself). I am concerned with students who actually hire people to write their papers or go out on line and cut and paste something vaguely relevant to an assignment and don't even bother to change the verb tenses or the context...and I swear sometimes they don't even read the article they have copied...
