Graham-Matheson, L. & Starr, S. (2013). Is it cheating or learning the craft of writing? Using Turnitin to help students avoid plagiarism. Research in Learning Technology, 21: 17218.
The authors make the following conclusions:
“The results of the study suggest that Turnitin is seen as a useful tool by students and may help up to half of students to avoid plagiarising, particularly the less confident students. There was a general understanding of the University’s reasons for using Turnitin and staff as a basis for helping students to avoid plagiarism valued it. The originality reports were seen to be very useful in discussions with students, particularly those having problems understanding plagiarism and academic writing requirements. Although the research was set up to assess the extent of the formative use of Turnitin, not its impact, it was clear, particularly from the interviews with academic staff, that Turnitin is a valuable tool in teaching students to understand, and avoid, plagiarism.”
