Network course is the sum of the teaching contents and activities of a certain subject expressed through the network, and it is a new manifestation of the course in the information age. It includes the teaching content organized according to certain teaching objectives and teaching strategies and the supporting environment of network teaching.

Among them, the network teaching support environment refers to the software tools, teaching resources and teaching activities implemented on the network teaching platform. Online courses have the basic characteristics of interactivity, sharing, openness, collaboration and autonomy.

It should be pointed out that because the teaching content includes teaching resources, online courses should usually include teaching resources (at least part of them); The online course that only involves the textbook itself is not an ideal (at least incomplete) online course.

However, in the actual development process, for the convenience of work (such as the need of division of labor or parallel work), teaching resources are sometimes separated or even juxtaposed with online courses-called "online courses and network resource development". But at this time, we should pay special attention: this distinction is only the need of development, and online courses should already contain online resources.

In short, online courses are distance courses conducted on the network through some software.
