This was a great way for me to introduce the topic of plagiarism. The slide show is intended to be used slowly as a catalyst for discussion, and slides should not be shown in rapid succession.
This PowerPoint is adapted from tutorials used at Indiana University (http://www.indiana.edu/~wts/pamphlets.shtml). Incorrect and correct paraphrasing is modeled, and there is opportunity for students to practice and share their paraphrasing skills.
Every year, my students particularly resonate with slide #9.
