With the development of information technology and the advent of Massive Open Online Course (MOOC) and Small Private Online Course (SPOC), various online courses which include a lot of new resources and new teaching methods have appeared. The application of advanced teaching resources and educational concepts can improve students' learning experiences. This paper proposes a hybrid closed-loop teaching model of analog circuit SPOC based on online live. The course design is centered on the improvement of students' abilities. An online course resources construction mode of self-built platform with excellent courses introduction is expounded. It enriches the number of online course resources and increases the forms of resource expression. In teaching design, here present the target classification method based on Bloom, the indicators of the Bloom model corresponding to the knowledge, process arrangement, and tests of analog circuits. It also discusses the rules and presentation methods of learning goals, and online experiment teaching based on simulation. Taking the analog circuit course as an example, the implementation methods of resource construction, goal setting, live class schedule, PBL summary, course test, experimental teaching are described. Finally, it summarizes the methods of teaching data collection and the idea of optimizing teaching design applying feedback data. The current data shows that online SPOC teaching mode is conducive to improving students' interest in learning and cultivating their comprehensive ability.
