Abstract: Using Hall's three-dimension structure theory and PDCA for reference to construct a three-dimensional MOOC teaching model in colleges and universities has the characteristics of short teaching time, prominent teaching knowledge, making full use of fragmentary time, facilitating communication and interaction, and high autonomy. However, there are still some problems, such as low completion rate of courses, insufficient personalized learning, lack of learning experience, difficult evaluation of teaching effect, and difficult certification of learning results. Teachers should pay attention to the emotional solution in MOOC teaching design, introduce advanced teaching theory, innovate teaching mode, and guide students to achieve personalized learning.
