《English Translation》
陈花: My students are driving me crazy. Almost all the homework they turned in this semester was correct, but their average score on the monthly exam actually dropped a lot.
刘娜: Could they be using AI to do it? I just read a report about professors at the University of Hong Kong who tracked more than 20,000 middle school students and found exactly this kind of situation.
陈花: Really? What exactly did the study say?
刘娜: Students who asked AI to give them answers directly saw their homework scores rise by 18%, but within six months, their monthly exam scores fell by an average of 20%, and two years later, their high school entrance exam scores were down by as much as 24%.
陈花: That's serious! I thought they'd finally gotten the hang of things. But almost everyone uses AI now, so we can't completely ban it, can we?
刘娜: The study said that if students only asked AI to explain how to solve a problem and still spent time working through it carefully themselves, there was basically no impact. The problem was directly copying and pasting answers. And the better a student's grades were, the greater the impact.
陈花: No wonder those top students in our class have been losing points on the big problems lately! Their parents probably don't even know they're using AI.
刘娜: That's very possible. The report said half of parents didn't even know which AI their children were using. We definitely can't rely on the kids' self-discipline alone.
陈花: Looks like I'll have to hold a class meeting tomorrow and have a serious talk with the parents too. Simply banning AI won't work. We need to help the kids understand for themselves how much they lose by copying answers.
