A New York University professor’s blog post is opening a rare public window on the painful classroom consequences of using plagiarism-detection software to aggressively police cheating students. And the post, by Panagiotis Ipeirotis, raises questions about whether the incentives in higher education are set up to reward such vigilance.
But after the candid personal tale went viral online this week, drawing hundreds of thousands of readers, the professor took it down on NYU’s advice. As Mr. Ipeirotis understands it, a faculty member from another university sent NYU a cease-and-desist letter saying his blog post violated a federal law protecting students’ privacy.
The controversy began on Sunday, when Mr. Ipeirotis, a computer scientist who teaches in NYU’s Stern School of Business, published a blog post headlined, “Why I will never pursue cheating again.” Mr. Ipeirotis reached that conclusion after trying to take a harder line on cheating in a fall 2010 Introduction to Information Technology class, a new approach that was driven by two factors. One, he got tenure, so he felt he could be more strict. And two, his university’s Blackboard course-management system was fully integrated with Turnitin’s plagiarism-detection software for the first time, meaning that assignments were automatically processed by Turnitin when students submitted them.
The result was an education in “how pervasive cheating is in our courses,” Mr. Ipeirotis wrote. By the end of the semester, 22 out of the 108 students had admitted cheating.
Some might read that statistic and celebrate the effectiveness of Turnitin, a popular service that takes uploaded student papers and checks them against various databases to pinpoint unoriginal content. Not Mr. Ipeirotis.
“Forget about cheating detection,” he said in an interview. “It is a losing battle.”
The professor’s blog post described how crusading against cheating poisoned the class environment and therefore dragged down his teaching evaluations. They fell to a below-average range of 5.3 out of 7.0, when he used to score in the realm of 6.0 to 6.5. Mr. Ipeirotis “paid a significant financial penalty for ‘doing the right thing,’” he wrote. “The Dean’s office and my chair ‘expressed their appreciation’ for me chasing such cases (in December), but six months later, when I received my annual evaluation, my yearly salary increase was the lowest ever, and significantly lower than inflation, as my ‘teaching evaluations took a hit this year.’”
Worse, Mr. Ipeirotis’ campaign aroused mistrust. Students were anxious, discussions contentious. He found teaching to be exhausting rather than refreshing. Dealing with the 22 cheating cases sucked up more than 45 hours “in completely unproductive discussions,” forcing him to focus attention on the least-deserving students, Mr. Ipeirotis said.
