As students gain access to sophisticated gadgets both at school and at home, educators are on the lookout for new kinds of cheating. From digitally inserting answers into soft drink labels to texting each other test answers and photos of exams, kids are finding new ways to get ahead when they haven’t studied.
YouTube alone has dozens of videos that lay out step-by-step instructions: One three-minute segment shows how to digitally scan the wrapper of a soft drink bottle, then use photo editing software to erase the nutrition information and replace it with test answers or handy formulas. The video has gotten nearly 7 million hits.
