The question arises, says Martin Weller, "why would you want to return to traditional exams, giving the damage they cause and the student preference? A week to complete essays using the internet and library resources is much more realistic a task than sitting in a sealed room and writing with a pen?" One answer obviously presents itself: " The essay format is in a plagiarism arms race with sites such as CourseHero and Chegg – it's a race HEIs can't win." But as he says, " it's probably not as difficult as we think to move away from the default essay or exam." And I think that the more we can use AI to assess larger and larger bodies of work, the harder and harder it will be to cheat the assessment system. Not that most students even want to.
