Faster homework, poor exam results: What AI is doing to students’ learning

Hundreds of millions of students are starting their school year, but AI is changing their learning process. A study led by David Stromberg and colleagues tracked 27,000 students in China, revealing that homework scores increased by 18% due to AI, while the time spent on each assignment decreased by 30%. However, monthly exam scores fell by 20% within six months, indicating a gap between schoolwork and actual learning.
