Khanmigo trial finds modest math gains comparable to Khan Academy practice

edworkingpapers.com Editor score 7/10

A two-year randomized trial across 18 Tennessee middle schools found small achievement gains, similar to Khan Academy practice without AI; students used the tutor infrequently. The usage data cautions against assuming access to an AI tutor leads to sustained engagement.
