Distance education refers to the transmission of educational information and the development of learning activities through TV, radio, internet and other distance education technologies. The development of distance education has gone through four stages, namely correspondence, TV University, traditional distance education and online learning.

correspondence

Without the support of multimedia, only the study of written materials is relatively simple and boring for learners.

TV university

Using video and other audio-visual tools for teaching, students need to go to designated places and watch videos for learning.

Traditional distance education

Through the network, learners learn recorded courses through the network.

online learning

Online learning is developed on the basis of distance education. In addition to recording courses on demand, there are also live interactive learning methods such as live classroom and live Q&A, which fully make up for the lack of communication in distance education. At the same time, it combines the functions of online examination room and knowledge base, allowing learners to check their own level and consult reference materials in an interactive way, thus realizing one-stop learning.
