In the last four years artificial intelligence in education (AIEd) has exploded like fireworks. By analysing almost 3,000 papers from 1990 to 2024, researchers found that publications jumped from a few dozen to over 600 in 2023, surpassing 1,200 by November 2024. The United States and China lead the race, with University of London and the University of California system at the core of the collaboration network.
Keywords tell the story: until 2020 “AI” and “machine learning” dominated, but from 2022 “ChatGPT” and “ethics” appear. This shift shows that, besides testing new technologies, the scientific community is increasingly worried about moral implications. In fact, 68 % of the most‑cited papers discuss ethical dilemmas, from data bias to student privacy.
The most common applications are in higher and medical education, where intelligent tutoring systems and personalised learning paths promise to make studying more tailored. Yet research on K‑12 remains scarce, leaving a crucial gap. The authors therefore call for stronger interdisciplinary collaboration and solid ethical guidelines, so AI can truly improve education without creating new problems.
