To combat copying another person’s work, the anti-plagiarism program Turnitin.com is now used at more than 8,000 high schools and colleges across the United States and in some schools abroad, reports the Setonian, the student newspaper at Seton Hall University. With more than 30 million papers submitted last year alone, the program has gained popularity since its creation over a decade ago. To catch plagiarism, whether it is intentional or unintentional, Turnitin works by comparing submitted papers to a large database of published works to check for similarities. But while some professors and even students say the software can be useful for catching plagiarism, others have voiced concerns over the program. "My teacher showed us a site that does this programming, and some of the papers had little to no highlighting while others were constantly highlighted," freshman Anthony SanMarco said. "Sometimes teachers believe the Web sites over the students, and I think there is a major conflict with this."
