Detecting & Preventing Plagiarism

Assistance in identifying plagiarism

  • Plagiarism.org includes information about and links to Turnitin and iThenticate
  • SafeAssign is supported by Brooklyn College through Blackboard, and works similarly to Turnitin

Tips for discouraging plagiarism

  • Avoid having students simply find answers. Encourage students to do their own thinking, not paraphrase the thinking of someone else. What are their thoughts and ideas on a given topic?
  • Ask questions which require students to make an inquiry or investigation.
  • Have students compile and turn in working bibliographies well in advance of term paper dates. This will require students to begin research at an early date, avoiding the temptation for last minute information downloads.
  • Have students maintain a research log. This will note the databases and indexes searched, search dates, keywords and subjects used, and a summary of search results.

Identifying plagiarized papers

The following can all assist you when you suspect a paper has been plagiarized.

  • Ask the student to recreate portions of the paper and see how closely this matches the syntax and sentence structure included in the paper in question.
  • Use search engines. Entering a four to eight word, distinctive phrase in a full text search engine will often yield the source of the plagiarism. Be sure to use the proper search techniques for locating phrases.
    Note: "entering phrases within quotation marks" works with most search engines the same way as using the "this exact phrase" box in the Advanced Search option of Google.
  • Search some of the common, full text databases used by undergraduates. Searching unique, selected phrases can help locate the exact article in which it appears.
  • Look for vocabulary not commonly used in this particular class.
  • Look at the citations included. Are they all from sources not likely to be encountered in undergraduate research? Are they outdated?
  • Look for statements at the end of the paper that acknowledge a source for the paper.
  • Look for unusual formatting, either a change in font or the formatting itself.
