Professor's Hidden Word Trick Catches 32 AI Cheaters
30 Jul
Summary
- Professor embedded an invisible word in exam prompts.
- 32 out of 35 students copied AI responses directly.
- Many students failed to proofread their AI-generated work.

A history professor at Alcorn State University employed an ingenious method to catch students submitting AI-generated work on a recent exam. By embedding an invisible instruction within the prompt, he tasked AI with nonsensically including the word 'Madagascar' in responses. Of the 35 students who took the exam, a remarkable 32 copied and pasted AI-generated answers, failing to notice the hidden directive.
The professor discovered that these students' essays contained bizarre, out-of-context references to Madagascar, revealing their reliance on AI. He noted that most students did not even proofread their submissions, highlighting a significant educational concern. This incident, occurring as educators grapple with AI's growing influence, fuels discussions on academic integrity and effective learning strategies.
