“Plagiarism is the practice of claiming or implying original authorship of (or incorporating material from) someone else's written or creative work, in whole or in part, into one's own without adequate acknowledgement. Unlike cases of forgery, in which the authenticity of the writing, document, or some other kind of object itself is in question, plagiarism is concerned with the issue of false attribution. (Wikipedia, retrieved 17:42, 25 March 2008 (MET))”
Plagiarism is one form of academic dishonesty. A related form is contract cheating, i.e. someone else produces the work. Kuro5hin has this interesting shadow scholar (2010) article, where a ghostwriter called Nathaniel Orenstam claims to have written about 5000 pages / year including a PhD thesis.
Plagiarism most often occurs when learners are left alone to produce a term paper and/or if classes are too big. When properly scenarized with a good project-oriented instructional design model, risks seem to be much lower.
- Turn assignments into real personalized projects (like mini-research projects).
- Change subject areas (i.e. paper topics) for each course.
- Require step-wise delivery, lists of themes, goals, questions, resources etc. Each of these must be reified as products and be discussed an evaluated. As an example see the C3MS project-based learning model.
- In the same spirit, require an electronic research trail (e.g. have them use a wiki to work on concepts)
- Tell students that prior work must be considered and that citations are encouraged, but also announce that you will use plagiarism detection software.
- Have students present their paper and ask them tough questions.
