In the classroom teaching of mathematics aided by information technology, student factor is also very important. There is no denying that there are great differences among students in intelligence, knowledge acceptance ability and thinking ability. Teachers'classroom teaching tasks include teaching knowledge goals to students and making students understand and accept them, and as much time as possible in the classroom for consolidation training. In the classroom teaching of mathematics assisted by information technology, teachers often have to allocate more class time to carry out inquiry learning, which is in great contradiction with the former in time allocation, there are also differences between the levels of students which also affect the effectiveness of teaching aids. In addition, the students are quite used to the traditional teaching method of mathematics. They listen carefully and take notes in class, and look at notes and do exercises after class. The students are already well adapted to this teaching mode, so they assist in the early stage of teaching, there is a process of gradual adaptation when students are just exposed to the new classroom form, which will also affect the teaching of high school mathematics assisted by information technology.
