When college students' attempts at paraphrasing become instances of potential plagiarism

In Study 1, undergraduates were asked to consider a scenario in which they were writing a paper and that, in the process of researching material for t he paper, they had encountered a relevant paragraph from a journal article which they had to paraphrase. The students were given a two-sentence paragr aph and were asked to paraphrase it to the best of their ability. Analysis indicated that between 41% and 68% of the paraphrased paragraphs mere "plag iarized" to some degree, where plagiarism was defined as the appropriation of strings of 5 consecutive words or longer. In addition, 52% of the paraph rased paragraphs contained from minor to serious distortions of the origina l material. In a second study, another sample of undergraduates was asked t o paraphrase a similar two-sentence paragraph from a textbook which was eas ier to read. This time between 9% and 19% of he paraphrased paragraphs evid enced similar amounts of appropriated text, although a comparable proportio n of distortions (50%) occurred. The combined results suggest that plagiari sm by college students may stem, in part, from their inability to process c omplex unfamiliar text.
