What are the basic characteristics of modern educational technology?

Modern educational technology is mainly based on information technology, that is, the system composed of educational technology means covering information technology is called modern educational technology. The process of education and teaching is essentially the process of information generation, selection, storage, transmission, conversion and distribution. Information technology refers to the application of various advanced technologies used in the above-mentioned series of processes.

Include microelectronic technology, multimedia technology, computer technology, computer network technology and remote communication technology. Introducing these technologies into education and teaching can greatly improve the information processing ability, that is, greatly improve the efficiency of teaching and learning.

The rapid development of modern science and technology has greatly increased the information resources owned by various media, including periodicals, papers, patents, books, software and so on. In 1950s, it only increased 1 times every 10 years, and then doubled in 2-3 years. The half-life of mastering knowledge is shortening, and the knowledge and skills accumulated by people will soon age and lose their original value.

Therefore, the efficiency of teaching and learning is particularly important. It should be noted that the traditional educational technology, such as projectors, slide projectors, televisions and other hardware, as well as the corresponding teaching software and methods, should be extended to the traditional point of view, that is, audio-visual education technology.
