Yanliu Primary School of Jinan, East China's Shandong province, has introduced an intelligent responder device in class, so that teachers can have a comprehensive view of the children's understanding of material covered in class.

In Chinese classes, teachers usually raise questions and ask one or several students to give the answer, but they do not know whether every student knows the answer.

With the intelligent device, the question will be shown on a screen, students choose the answer with a responder and each student's choice will appear on the screen.
