In the traditional teaching mode, the teacher is the master of the classroom, and students are in a passive learning state for a long time, unable to exert their subjective initiative and innovative consciousness. The use of information technology can optimize the teaching environment, and students can gain more knowledge and broaden their horizons through rich learning materials. In junior high school mathematics teaching, using information technology can create various three-dimensional vivid teaching situations for students, stimulate students' sensory ability and learning desire, let students observe and think spontaneously, and fully mobilize students' interest in learning mathematics.
