The application of educational technology advocates the guidance of advanced educational ideas, concepts and theories; Educational technology takes learning process and learning resources as the research object (generally emphasizing teaching process and teaching resources); The research content of educational technology includes five aspects (research category): the design, development, utilization, management and evaluation of teaching process and teaching resources.
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.
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.
Learning process is a cognitive process in which learners acquire knowledge and skills through interaction with information and environment. Learning resources are all kinds of information and environmental conditions to be used in the learning process.
The new teaching theory requires students to change from passive recipients of external stimuli to active learners who can actively process information, and teachers should provide information resources and learning environment that can help and promote students' learning.
Starting from the needs of social development and human development in the 2/kloc-0 century, we should build a social education system that can support comprehensive learning, autonomous learning, collaborative learning, creative learning and lifelong learning.
