[AI Detection Tools Are Not the Answer to Cheating in Classrooms 

– A New Way of Assessment Is Needed]

  With the rapid development of AI (Artificial Intelligence), schools are also trying to use AI in many ways. One common method is using AI detection software to stop cheating. However, recent research and teachers say this technology is not always reliable or effective.

  AI detection tools usually analyze something called “perplexity” and “burstiness” to decide if a sentence was written by AI. But this method is not perfect. It can be unfair to students who are still learning English. Sometimes, the tool can even say a human wrote text with AI, which is called a “false positive.”

  For example, Turnitin’s AI detector says it is 99% accurate. But even a 1% false positive rate can be a big problem. At the University of Winnipeg in Canada, students submit around 250,000 assignments every year. If 1% are marked wrongly, that’s about 2,500 false cheating cases.

  According to a survey by the Center for Democracy and Technology, 68% of public school teachers in the U.S. (K–12 level) said they use AI detection tools. Some schools in Canada are also doing the same.

  But relying too much on AI detection can cause stress for both students and teachers. It also does not solve deeper problems with how schools test and grade students. Professor Michael Holden from the University of Winnipeg said that many assignments are now done at home, without a teacher watching. In this case, it's hard to know if the student really did the work themselves. He said we need to change how we assess students, instead of just making AI detectors stronger.

  Experts suggest using a type of grading called "formative assessment," which looks at the whole learning process — like drafts, progress, and feedback. They also say it’s important for students to take part in class and work on real projects where they solve problems by themselves.

  Professor Holden said, "In the age of AI, education needs to change how we evaluate students. We must understand what students truly know and what skills they really have. That means moving to new ways of assessment that focus more on the learning process and students' abilities."
