What does research tell us about AI and student learning?
Research into AI tutoring shows promise, but the way it’s used matters. The important question is what students can understand, remember, and do independently afterwards.
01
The learning happens when they take part.
02
Getting it right isn’t the same as learning it.
03
How AI helps makes a difference.
About this research
These findings come from studies of different tutoring systems and learning activities. They are not results from a study of Astra AI.
Students learned more than twice as much.
In a Harvard study, students using a purpose-built AI tutor achieved more than double the learning gains of students in an active-learning classroom - in less time.
