Experts agree AI will be important in 21st-century education—but how? While academics have puzzled over best practices, China hasn’t waited around. In the last few years, the country’s investment in AI-enabled teaching and learning has exploded. Tech giants, startups, and education incumbents have all jumped in. Tens of millions of students now use some form of AI to learn—whether through extracurricular tutoring programs like Squirrel AI, through digital learning platforms like 17ZuoYe, or even in their main classrooms. It’s the world’s biggest experiment on AI in education, and no one can predict the outcome.
