In order to solve the problems that students are not interested in the theoretical study of “Child Development and Educational Psychology” and the effect cannot be monitored, so as to better achieve the teaching and learning goals of the course,？we are guided by theories such as constructivism, behaviorism, and information learning theory？based on the UMU platform in accordance？with the requirements of the Ministry of Education of China for the？construction of first-class courses. The subjects of this study are 235 students majoring in elementary education in Baise University.？The teaching reform of “Child Development and Educational Psychology” is divided into two semesters. The first semester uses blending learning. According to the completion rate of students on the UMU platform, they are divided into high completion rate group, medium completion rate group and low completion rate group.
