In two studies undergraduate students were given an original paragraph and several rewritten versions of the paragraph, some of which were plagiarized (e.g., without a citation, superficially modified from the original) and some correctly paraphrased. Students were asked to determine whether each rewritten version had been plagiarized or correctly paraphrased. Approximately 74% of the students in both studies correctly identified the paraphrased versions. However, some of the plagiarized versions were misidentified as having been correctly paraphrased by as many as 40% to 50% of the students. Results suggest that students are often unclear as to what constitutes plagiarism and correct forms of paraphrasing.
