Educational technology refers to the application of modern science and technology in education. After the 20th century, with the development of modern science and technology, modern technologies such as slide show, projection, film, recording, video recording, radio and television have been widely used in education, which has expanded the scope of educational and teaching activities and improved the efficiency and quality.
From 65438 to 0974, the United States launched the first "practical technology satellite" dedicated to teaching, marking the development of modern educational technology to a new stage. Since then, people have further discussed the new topics brought by the latest achievements of computer, microelectronics and optical fiber communication to the development of educational technology.
The definition of educational technology published by the American Association for Educational Communication and Technology (AECT) in 1994 is generally recognized in China: educational technology is the theory and practice about the design, development, utilization, management and evaluation of learning resources and learning processes. Its original English text is: Teaching technology is the theory and practice about the design, development, utilization, management and evaluation of learning process and learning resources.
This definition expresses the research object of educational technology as a series of theoretical and practical problems about "learning process" and "learning resources", which changes the previous formulation of "teaching process" and embodies the great change of modern teaching concept from teaching-centered to learning-centered, from imparting knowledge to developing students' learning ability.
