AI can raise scores and still undermine learning. When AI substitutes for mental effort, it can reduce opportunities to develop critical thinking.
Critical thinking develops when learners analyse, evaluate, question and reason. If AI does these tasks for them, students may have fewer opportunities to build those cognitive skills themselves.
In one study of nearly 27,000 secondary students, those who used AI for their homework earned higher scores and completed it in less time. But when the same students completed exams without AI, their results declined within six months, most sharply among those who had completed their homework the fastest.
At Digital Learning Week, UNESCO promotes reflection and dialogue on how educators can use AI systems to foster critical thinking and learning, instead of doing the thinking for students.
