humphrey_shi · x · 2026-09-28
A randomized controlled trial published in Scientific Reports compared an AI-powered tutor with in-class active learning in an authentic college setting. The paper has drawn 213k accesses and 202 citations.
- The custom AI tutor was designed around the same evidence-based pedagogy as the in-class lessons, keeping the comparison fair.
- Result: students learned significantly more in less time with the AI tutor and reported more positive perceptions.
- Professor Humphrey Shi adds that as AI scales personalized learning, universities should redirect human attention toward curiosity, judgment, creation, community, and character.
