How AI Can Spot Exam Cheats and Raise Standards (ft.com)
AI is being deployed by those who set and mark exams to reduce fraud -- which remains overall a small problem -- and to create far greater efficiencies in preparation and marking, and to help improve teaching and studying. From a report, which may be paywalled: From traditional paper-based exam and textbook producers such as Pearson, to digital-native companies such as Coursera, online tools and artificial intelligence are being developed to reduce costs and enhance learning. For years, multiple-choice tests have allowed scanners to score results without human intervention. Now technology is coming directly into the exam hall. Coursera has patented a system to take images of students and verify their identity against scanned documents. There are plagiarism detectors that can scan essay answers and search the web -- or the work of other students -- to identify copying. Webcams can monitor exam locations to spot malpractice. Even when students are working, they provide clues that can be used to clamp down on cheats. They leave electronic "fingerprints" such as keyboard pressure, speed and even writing style. Emily Glassberg Sands, Cousera's head of data science, says: "We can validate their keystroke signatures. It's difficult to prepare for someone hell-bent on cheating, but we are trying every way possible."
Indeed. When a person's whole future life is on the scales, the weight needed can't just be "upon preponderance of evidence" or "beyond reasonable doubt". Even a 100,000:1 risk of a false positive, when combined with the data that around 3.8 million Americans will obtain a university degree this year, that means that dozens of them will trigger false positives and risk their degree taken away from them by machines and the machine-like humans who operate them.
When faced with science that says it's only a 1 in 100,000 chance that you're innocent, good luck convincing enough review board members that you're an exceptional case and innocent.
Yes. So I can call myself an AI expert now? Also, let me know if Eliza is now considered AI.
Well, if I were on such a review board, I would likely find that the "educators" were so incompetent, that I cannot actually judge the performance of the student.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
