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 projections, projections, films, audio and video recordings, radio, and television have been widely used in education, expanding the scope of education and teaching activities, and improving efficiency and quality.

In 1974, the United States launched the first "practical technology satellite" dedicated to teaching, marking a new stage in the development of modern educational technology. Since then, people have further explored the new topics brought about by the latest achievements in electronic computers, microelectronic technology, and optical fiber communication to the development of educational technology.

The definition of educational technology issued by the American Association for Educational Communication and Technology (AECT) in 1994 is a generally recognized definition of educational technology in China: educational technology is the theory and practice of the design, development, utilization, management and evaluation of learning resources and learning processes. The original English text is:

instructional technology is the theory and practice of design,development,utilization,management and evaluation of processes and resources for learning.

This definition describes the research object of educational technology as a series of theoretical and practical issues about "learning process" and "learning resources", which changes the previous term of "teaching process" and reflects the major change of modern teaching concept from teaching-centered to learning-centered, from imparting knowledge to developing students' learning ability.

Go read the books on educational technology.

AECT 1994 Definition: The theory and practice of designing, developing, utilizing, managing and evaluating processes and resources in order to facilitate learning.

Design: It mainly includes four main aspects of theory and practice: teaching system design, information design, teaching strategy design, and learner characteristics analysis.

Development: It is the process of translating a design into a physical form. It is necessary to use audiovisual technologies such as printing technology, radio and television, computer-aided technology, integration technology, etc.

Utilization: including the application, innovation and promotion, implementation and institutionalization, policies and regulations, etc.

Management: including project management, resource management, teaching system management and information management.

Evaluation: including problem analysis, reference standard evaluation, formative evaluation and summative evaluation.

Previous definitions of educational technology in AECT.

Definition. Audiovisual communication is a branch of educational theory and practice that focuses on the design and use of messages that control the learning process. Its practical aim is to make efficient use of every method and ** in communication to reach the full potential of each learner.

Definition by the American Council on Instructional Technology:

Instructional technology refers to the ** that arose from the communication revolution and that can serve the purpose of teaching together with teachers, textbooks, and blackboards. It is based on the study of human learning and transmission, and uses a combination of human and non-human resources to achieve the purpose of more effective teaching.

Definition. Educational technology is a field that promotes human learning through the systematic identification, development, organization, and utilization of all learning resources, as well as through the management of these processes.

Definition. Educational technology is a complex, integrated process involving people, procedures, ideas, equipment, and organizations that aims to analyze problems that permeate all aspects of human learning and to design, implement, evaluate, and manage solutions to those problems.

Don't be too dogmatic, just make sense of it. The answers of enthusiastic netizens are available for reference.

If you look at the textbooks of educational technology, you can study educational technology! It's written in the book and it's detailed.

Summary. Modern Educational Technology (AECT) is defined as "the use of new technologies, ideas and methods to identify, develop, use and manage information and communication technologies to improve teaching, learning and research". As education and technology evolve, so does the definition of modern educational technology.

Computers, networks and other information technologies have become an indispensable part of teaching and learning, and they will gradually replace traditional classroom teaching methods, helping educators to grasp the teaching content more efficiently, enhance students' understanding of the teaching content, effectively stimulate their interest in learning, and improve the quality of teaching. Through intelligent teaching systems, big data analysis, virtual reality and augmented reality and other technologies, modern education technology is more perfect, and teaching becomes more efficient and entertaining.

Your understanding of the evolution of the definition of modern educational technology according to the definition of +aect+.

OK Modern Educational Technology (AECT) is defined as "the use of new technologies, ideas and methods to identify, develop, use and manage information and communication technologies to improve teaching, learning and research". With the development of education and technology, the meaning of modern chiropractic technology is also evolving. Computers, networks and other information technologies have become an indispensable and important part of teaching and learning, and they will gradually replace the traditional classroom teaching methods, helping educators to grasp the teaching content more efficiently, and at the same time enhance students' understanding of the teaching content, effectively stimulate their interest in learning, and thus improve the quality of teaching.

Through intelligent teaching systems, big data analysis, virtual reality and augmented reality and other technologies, modern education technology is more perfect, and teaching becomes more efficient and entertaining.

94 Definitions: The theory and practice of instructional technology in designing, developing, utilizing, managing and evaluating resources and processes in order to facilitate learning.

05 Definition: Educational technology is the research and ethical practice of creating, utilizing, and managing appropriate technological processes and resources to facilitate learning and performance.

Similarities: 1. It is clearly stated that the research object of educational technology is the learning process and learning resources.

2. It is pointed out that the research field of educational technology has been changed to educational technology and design technology.

3. Emphasizing that educational technology is a theoretical and practical discipline.

Differences: 1. The name "Instructional Technology" is replaced by the name "Educational Technology"; 2. The two research fields of "Theory and Practice" were changed to "Research and Ethical Practice"; 3. The two research objects of "learning process" and "learning resources" are transformed into "processes and resources that are used to promote learning and improve performance, and have appropriate technology (support)"; 4. The five research categories of "design, development, utilization, management and evaluation" of learning processes and learning resources have been reduced to three categories: "creation, use and management" of related processes and resources. 5. Change the original "for learning" to "promote learning". In order to learn, the emphasis is on "learning", and the promotion of learning emphasizes both "learning" and "teaching"; 6. In addition to emphasizing the relevant processes and resources to promote learning, it is also emphasized to improve performance.

Compared with the 94 definition, the consideration of "performance" is added, and the 05 definition focuses on both the learning process and the learning outcome, and also shows that improving corporate performance through training is also an important research and application field of educational technology. **。
