Peter Biello: Natasha, thank you very much for speaking with me. Natasha Singer: Thank you for having me on. Peter Biello: Lots of colleges and universities have used some form of software to monitor students during exams that because of the pandemic needed to be taken remotely. Dartmouth was using a software called Canvas. How did Canvas enable Dartmouth to identify what seemed to the school like evidence of cheating? Natasha Singer: It's a fascinating story because Dartmouth actually require students to use a separate software called Exam Soft that locks down the devices they're taking exams on. But they notice that even though the student's primary devices were locked, there seemed to be activity on different software called Canvas, and students are required to have a secondary device nearby. So they thought that students were looking up stuff on Canvas, which is, of course, software platform that millions of students use. And so Dartmouth decided that there was enough evidence of possible cheating of students using this Canvas platform on secondary devices like an iPad while they were taking exams on their primary laptops. But they decided to do this retrospective analysis of every exam that first and second year medical students had taken since last fall.
