Experimental Design

Experimental Design
We first recruit middle schools to participate in our experiment around China, with the help of the iFLYTEK. In each recruited school, we then randomly several classes in the 7th grade into treatment group and some other classes in the same grade into control group.

For the treatment group, each student is arranged to use an AI learning device provided by the iFLYTEK to do math exercises. The device is designed to be capable of providing adaptive exercises to the user’s mastery of learning materials, and to help the user finally grasp all key points of the course. This feature is achieved by taking advantage of massive question database, AI algorithm and cloud computing technology. Except for this, all other schedule and arrangement of teaching and learning remain unchanged.

For the control group, we do not make any interferences.
