2. In the process of human civilization, the application of any information media technology in education has had a great impact on education. The technical progress represented by the appearance of writing and printing has triggered great changes in the field of education, and the application of IT (information technology) in education will become the third milestone in the development of human culture.
3. For a long time before writing appeared, the form of education was mainly dictation, plus facial expressions and gestures. Language technology characterized by eloquence and oratory has always been the most important educational technology at that time. However, when people need to preserve, copy or spread the knowledge, experience and ideological information in educational content for a long time, the limitations of language technology are highlighted. The emergence of writing technology has broken through this limitation and gradually become the dominant technology in educational activities. Its appearance makes written language join the educational activities that used to be carried out only by spoken language and action language, which not only expands the content and form of education, but also greatly improves students' abstract thinking and self-learning ability. In particular, the invention and application of printing technology has made a revolutionary leap in text communication technology, and triggered an educational group with text information as the object of communication, making printed books and textbooks the main carriers of culture, thus promoting the spread of culture and the popularization of modern education. The appearance and application of these two information communication technologies are two milestones in the development of human culture.
4. Educational technology has experienced traditional technologies (spoken language, writing, blackboard, chalk, pictures, models and objects, etc.) and audio-visual media technologies (photography, slide show, projection, radio broadcasting, movies, television and language laboratories, etc.). ), and entered the information technology stage based on computer technology and communication technology in the 1990s. High-tech played the main theme of the grand cross-century movement with unprecedented acceleration. In the process of the transformation of human civilization from the industrial age to the information age, "multimedia" and "information superhighway" are changing people's working methods, learning methods, thinking methods, communication methods and even lifestyles at an alarming rate. Undoubtedly, the application of contemporary information technology in education will become the third milestone in the development of human culture.
