Turnitin today announced that an eight-year efficacy analysis shows that high schools using the company’s plagiarism prevention technology are currently experiencing at least a 33 percent drop in unoriginal content in their students’ writing. The study—which analyzes more than 36 million student papers from 2,862 high schools—also indicates that surveyed schools in 43 of the 50 states show a reduction of as much as 83 percent in students’ unoriginal writing over the past eight years, Turnitin says. “There’s been a good deal of accepted research showing how plagiarism is a growing problem in education,” says Chris Caren, chairman/CEO of Turnitin, in the announcement. “This study reveals how consistent use of educational technologies deliver measurable improvements to student outcomes by engaging students around issues of proper research, citation and writing.” Turnitin offers a cloud-based service for originality checking, online grading, and peer review, which aims to save instructors time and provide feedback to students. The company will discuss the findings of its plagiarism study during a webcast on Thursday, October 10. An interactive map, showing the full results of the study along with its methodology, is also available online.
