The authors used a mixed-methods approach to evaluate the use of Turnitin originality detection software in a graduate social work course. Qualitative analysis of student responses revealed positive and negative spent completing assignments, and the tone of the class. Quantitative analysis of students' originality scores indicated a short-term reduction in student plagiarism, although the full level of decline was not maintained in the long term. Implications for originality issues in social work education and social work practice are presented. (Contains 3 tables and 2 figures.)
