1 multimedia
The multimedia trend of modern educational media is mainly manifested in two aspects, namely, the application of multimedia technology and the application of multimedia system formed by multimedia optimization combination.
Computer multimedia technology has the advantages of many sensory stimuli, large information transmission, high speed, high transmission quality, wide application range, convenient use, simple operation and strong interaction, which makes its application momentum in the field of education unstoppable, thus becoming the mainstream technology in educational technology.
2. Establish a working network
The networking trend of educational technology is also mainly manifested in two aspects: the rapid development of Internet applications and the rapid development of satellite TV networks. Since 1970s, satellite TV has developed rapidly after it entered the teaching field. At present, China's existing broadband network cable TV has an increasingly large user base in large and medium-sized cities, and the public telephone switching network has also extended to thousands of households, so some people put forward the idea of network university.
Based on CATV and PSTN, this plan takes the integrated information service platform composed of intelligent network application platform and multimedia application platform as the core, and relies on existing universities to build an online university with certain interactive ability, that is, "the integration of three electricity (computer, TV and telephone)".
3. Diversified application modes
Generally can be divided into five types:
1, a multimedia teaching form based on audio-visual media technology.
2. Distance education based on satellite communication technology.
3. Multimedia teaching form based on computer multimedia technology.
4. Network teaching form based on Internet and other network technologies.
5. Virtual reality teaching form based on computer simulation technology.
We are familiar with the first four teaching forms, but not with virtual reality. The main characteristics of virtual reality technology can be summarized as real-time interaction, multi-perception, existence and autonomy. With the development of economic and technical conditions, virtual reality technology will be one of the main development trends of educational technology in 2 1 century.
The Development of Educational Technology in China
1. The earliest educational technology in China is mainly audio-visual technology, and the development and application of other technical means in education, which is what we usually call audio-visual education means. The form of distance education with radio, television and satellite as the main body has promoted some changes in teaching organization, learning methods and teaching methods.
2. In the middle and late 1980s, the continuous maturity and progress of computer network technology and communication technology brought about the rapid development of information dissemination technology and the revolution of educational technology and even educational methods.
3. Following the "Opinions on Strengthening Educational Technology in Colleges and Universities" issued by China's Ministry of Education, in June 1999, the "Decision of the State Council and the Central Committee of the Communist Party of China on Deepening Educational Reform and Promoting Quality Education in an All-round Way" was issued, which put forward a more clear task for the development of educational informationization and modernization of teaching methods: to vigorously improve the modernization level of educational technologies and means and improve the degree of educational informationization.
4. Educational technology is moving from the edge of educational reform to the center, and its position and role in the educational system are unprecedented.
5. Using various theories and technologies, through the design, development, utilization, management and evaluation of teaching and learning process and related resources, the theory and practice of education and teaching optimization are realized.
6. Under the new situation, educational technology, as the main starting point of educational informatization, needs to follow up the development, realize self-innovation and theoretical breakthrough, grasp the development of educational informatization and the specific reality of each region from a macro perspective, outline the new form of future education from point to point, and help the development of national rejuvenation education.
