A teacher and an AI tutor after school.
A World Bank randomized trial studied a six-week, teacher-supported after-school English program in Edo State, Nigeria, where first-year senior secondary students used Microsoft Copilot powered by GPT-4.

The human problem
Students need responsive practice and feedback, but individualized tutoring is often unavailable in public-school settings.
The prior constraint
Earlier education technology evidence often came from wealthier settings or depended on specialized, costly software.
AI’s actual role
Students used a generative-AI tool for curriculum-aligned English grammar and writing work after a teacher introduced the lesson and guided the sessions.
The documented result
The randomized evaluation reported a 0.31 standard-deviation improvement on its assessment covering English topics, AI knowledge, and digital skills after the six-week intervention.
Why it may matter
The finding concerns a designed human-and-AI learning setting in a public-school context, rather than assuming chatbot access by itself creates learning.
Limitations
The intervention was short and teacher-supported, so it does not establish effects of unsupervised chatbot use.
The central assessment was designed for the study; it does not establish long-term retention or broader academic outcomes.
Results from Edo State and English instruction may not transfer directly to other subjects, languages, or school systems.
Unresolved questions
Do gains persist, transfer to other learning, or change school completion?
What teacher preparation and infrastructure are necessary?
How can students retain agency when the system can generate answers?
