BYOD mode is a new form of intelligent education and an inevitable requirement for the development of higher education informatization. A model of influencing factors of preschool education satisfaction based on BYOD mode is constructed by the study, which selects relevant factors and sets research hypotheses. Taking the preschool education majors of five colleges and universities in a certain place as an example, the study collects data and then carries out correlation analysis and step-by-step regression analysis to analyze the degree of influence of each variable on preschool education majors’ course satisfaction. Combined with relevant concept combing, a teaching model based on the OBE concept for preschool education major courses is constructed, based on which intervention experiments are carried out on two preschool education major classes of students in a certain university to investigate the teaching effect of the constructed BYOD teaching model. All seven selected variables positively affected the satisfaction of the preschool education major program, with learning motivation (0.648) and perceived validity (0.407) having the most significant positive effects on the most predictive factor, learning satisfaction. After the teaching experiment, students in the test class improved by 19.05% and 17.63%, respectively, in learning intentions and overall quality and were 15.46% and 15.27% higher than the control class. The BYOD-based teaching model used in preschool education programs has a good effect on students’ learning intentions and comprehensive quality.
