The invention relates to a course-opening system for supporting a course teacher to open an exploration-type learning course, being a new teaching and learning mode in a network environment, and belonging to the field of education technology services. The invention creatively designs a course-opening system for supporting a course teacher to open the exploration-type learning course, and the system comprises a network platform, a digital learning material, a teaching process and accompanying services. On the basis of reserving the advantages of the traditional teaching, by means of the Internet, through the mixed course-opening mode combining online, offline, in-class, after-class, dispersed and the centralized modes, the autonomous exploration study of the students is realized. The selection right and the self-defining right are given to the course teacher, so that courses with different styles and characteristics can be respectively opened by a plurality of course teachers who uses the system at the same time. An exploration task selection right is given to students, and the enthusiasm of the students to study is stimulated. The course-opening mode is suitable for being used fordeveloping the exploration-type learning courses under various types of school network environments. The system comprises nine modules, namely a virtual class module, an exploration task module, a homework display module, an interaction module, an activity competition module, a learning evaluation module, a personal space module, a digital learning material module and an accompanying service module. According to the system, three processes are implemented, namely a teacher guide process, a student learning process and a manager management process.
