Turnitin • Turnitin is a text matching service, used to identify students copying from external services and colluding with other students
Contract Cheating • Work produced using contract cheating is original, so Turnitin will not identify sources for this work
Attribution • The challenging process where a contract cheating detective tries to identify the university that student contract cheating requests found online are from • Most of our work is based around the Freelancer.com agency site
Some Success • Running student contract cheating requests through Turnitin has started to show interesting results for a small number cases
Turnitin Example 1 Large match to assignment brief
Turnitin Example 2 Multiple small hits from the same source
Turnitin Example 3 No matches when first posted But received request to view from another university when it matched one of their assignments 2 months later
Turnitin Example 4 Brainmass.com provides stock answers Turnitin Report from Posting in Jan 2014 Shows that same stock assignment has been used before in previous years
Turnitin Example 5a Freelancer request to re-write assignment Source located by Turnitin
Turnitin Example 5b We try to follow up other postings. This was made by the same person as before and matches the same source
Turnitin Example 6 Multiple sources for EdExcel courses Example of “false positive” matches
Turnitin Example 7 Turnitin also matches public web sites Particularly useful if “old data” not found by Google
Turnitin Example 8 Multiple hits, but no response to Turnitin requests Possible problems: Staff Turnover University no longer registered with Turnitin
Current Use • Turnitin is now allowing contract cheating detectives to attribute work that has not been identified using other methods • 29% success rate based on sample in paper • Recommendation – academics should load all assignment specifications into Turnitin
