Turnitin is widely recognised for its role in preventing plagiarism. However, this perspective is an oversimplification. The Turnitin suite encompasses a variety of useful features designed to enhance the quality of writing and feedback. In this session, we will discuss what Turnitin is capable of and, importantly, its limitations. We plan to explore some unusual cases where Turnitin yielded unexpected results, explaining how to interpret these occurrences. Additionally, we welcome any questions you might have regarding the application of Turnitin in your specific context. Our goal is to provide insights into best practices for using Turnitin and to suggest supplementary strategies that, when combined, may more effectively address plagiarism.
