Recently there has been an increasing interest in plagiarism detection systems, such as the web-based Turnitin system. However, no study has so far tried to look at how students react towards those systems being used. This exploratory study examines the attitudes of students on a postgraduate module after using Turnitin as their standard way of submitting work and getting feedback. Overall, students reacted positively towards the system. However, the study also found evidence of a group of students who were less positive, which seemed to be a result of their insecurity about how to quote correctly. (Contains 1 figure and 5 tables.)
