#AI #GenerativeAI #AIDetectors #Universities #HigherEd: "About two-thirds of teachers report using an AI checker regularly, according to a survey of more than 450 instructors published in March by the Center for Democracy & Technology.
The best AI writing detectors are highly accurate, but they’re not foolproof. Businessweek tested two of the leading services—GPTZero and Copyleaks—on a random sample of 500 college application essays submitted to Texas A&M University in the summer of 2022, shortly before the release of ChatGPT, effectively guaranteeing they weren’t AI-generated. The essays were obtained through a public records request, meaning they weren’t part of the datasets on which AI tools are trained. Businessweek found the services falsely flagged 1% to 2% of the essays as likely written by AI, in some cases claiming to have near 100% certainty.
Even such a small error rate can quickly add up, given the vast number of student assignments each year, with potentially devastating consequences for students who are falsely flagged. As with more traditional cheating and plagiarism accusations, students using AI to do their homework are having to redo assignments and facing failing grades and probation."
