Turnitin (2012), The Plagiarism Spectrum, Instructor Insights into the 10 Types of Plagiarism.
A MUST READ. Turnitin, a private company that sells plagiarism detection services, surveyed 879 secondary and college level educators to determine how most students plagiarize. This report with excellent statistical graphics, shows the 10 most common types from "Clone" when the student copies word for word, to "404 error" in which the student cites a source but it is erroneous or made up. The range of possible ways to plagiarize is astounding. The article gives actual examples of each type of plagiarism using the same plagiarized original work for each example.
