In order to solve the teaching problems such as the single form of traditional teaching mode and the unsatisfactory effect of classroom teaching, this paper proposes a new teaching mode based on the fusion of multimodal multimedia information. The main research contents are: Firstly, the concept of modal and multi-modality is expounded in detail, and the representation form of modal carrier multimedia is described in detail. Secondly, the problems existing in traditional teaching are analyzed. Finally, in Solutions Statistical Package for the Social Sciences (SPSS), the normal equation is solved by using the least square method, and the statistical data is saved in the data file to realize the nonlinear analysis of the data to realize the change of multimodal information technology in preschool education by using nonlinear analysis technology. The results show that in the traditional preschool education mode, the number of students with good learning status in the class is always kept at 20%, and the number of students with poor learning and ordinary learning is almost the same. In the multi-modal teaching mode, the number of outstanding students is increasing by 12% every week, accounting for 60% in the last week, which is more than half of the number of normal classes. It clearly shows that students feel the innovation and interest of multi-modal technology integration teaching, and have a high interest in learning. After the integration of multimodal information technology, the teaching classroom of preschool education has become rich and the students' practical ability has been improved. The research in this paper provides a theoretical basis for the integration of multimodal information technology in college teaching, which is helpful for more research on improving the quality and effect of classroom teaching in colleges and universities in the future.
