Quinn Ferebee was feeling anxious. It was February 7, the sophomore’s 10-page term paper was due, and Turnitin.com had just marked it as heavily plagiarized.
“[Turnitin] said [my paper] had 60% similarity when I submitted it,” she said. “It kind of stressed me out because I thought I might have actually plagiarized.”
But she hadn’t.
The reason Turnitin.com flagged her paper for similarity was because she had already submitted much of it in a previous draft assignment, so Turnitin believed that she was plagiarizing her own work.
Ferebee was one of many sophomores to experience this phenomenon while submitting the final draft of their term paper, an issue that would not have occurred in years prior because Turnitin.com just returned to St. Mary’s this school year.
Turnitin.com is an online tool that detects plagiarism by comparing students’ submissions with online sources, an archive of previously submitted works and online sources. Students submit their writing to Turnitin.com via Schoology, and the tool then assesses the work for plagiarism and presents its findings to the instructor.
Ferebee’s English Teacher Julie Bielskis knew to overlook the flagged submissions, but the incident highlights the growing pains associated with this new technology.
For Caroline Goodman, English teacher and upper school technology specialist, the advantages to using Turnitin.com are significant. She believes that its value is not just as a method for catching plagiarized work, but also as a writing assistant. Along with detecting plagiarism, Turnitin.com also provides grammar checks through Turnitin Draft Coach™ available on Google Docs and introduces students to the proper way of citing sources.
Turnitin markets itself as a tool that helps students learn how to use sources in their writing, so teachers are using it well and guiding students to use it well also.” — Caroline Goodman
Head of Upper School Dr. Lauren Rogers similarly believes that the accessibility of this tool allows students to learn from their mistakes in dealing with sources to prioritize well-constructed and meaningful writing in the classroom.
“As students grapple with ideas and research, especially as young scholars, they are navigating how to share the research and findings of others in their own voice and also manage to cite and funnel information to create their own argument,” Rogers said, “Turnitin …gives them an additional tool to check and verify.”
Though St. Mary’s used Turnitin 10 to 12 years ago for plagiarism detection, the administration removed it due to a lack of usage. Head of Upper School Dr. Lauren Rogers believes that the resurgence of AI as a tool for plagiarism made bringing Turnitin back this year necessary.
“We are in the midst of the rise of artificial intelligence as a tool that’s easily accessible to pretty much anybody,” Rogers said. “St. Mary’s has had a long partnership with Turnitin. We haven’t used it in the last couple years, but they offered this new platform where you could run information through and check for sources because of the change in AI. We thought that this is something that would be a really nice addition to our classrooms.”
Turnitin began offering AI detection in April of 2023.
With the rise of ChatGPT in the winter of 2022, AI usage in the classroom became a lingering concern particularly within the English and history departments at St. Mary’s.
“Everyone was in a little bit of panic with ChatGPT,” Goodman said. “As we were thinking about what we could do, I reminded everyone that there are plagiarism detectors that schools can purchase.
Honor Council President Maggie Kustoff believes that Turnitin.com can be a useful tool for faculty to ensure that students are doing their own assignments.
I think it’s helpful to make sure that everybody is putting in the same amount of effort.” — Maggie Kustoff
However, the AI-detecting tool within Turnitin is not always accurate.
Turnitin claims that its AI detection software has a false positive rate of just 1% (meaning one paper in 100 would be incorrectly flagged as AI-written) but others attempting to verify this claim have found a much higher rate. Vanderbilt University announced in August 2023 that they were disabling the AI-detection feature because as more and more of their students submit work, more students would be falsely flagged for plagiarism.
According to Director of Studies Dr. Kate Stakem, the honor council at St. Mary’s has not yet used Turnitin.com as evidence in an AI case, but the software is available if needed in the future.
These false positives do pose a concern for Turnitin.com’s accountability, but the administration still has enough faith in this new tool and its benefit to reassure that it is here to stay.
“It helps [students] understand how to cite and when to cite, and how to practice [this skill] in this really shifting landscape,” Rogers said. “[It’s] really important for us to adapt to give students a tool to make sure that they are being mindful and adaptive of the conversation [of AI] that we’re seeing in the newspaper and all over social media.”
