This sentence is one-sided. Nowadays, educational technology is not just the production of educational courseware. The thinking and teaching methods of teachers have also changed. Then the way of teaching will change.

Modern educational technology is a modern educational means and method system that applies modern educational theory to education and teaching practice. Includes the following aspects:

1, the modern technical means applied in education and teaching, that is, modern educational media;

2. The method of using modern educational media to carry out educational and teaching activities, that is, media teaching method;

3. The systematic method of optimizing the education and teaching process, that is, teaching design.

Summarizing these two authoritative definitions, we can understand the connotation of educational technology from three aspects:

1. Educational technology is the general name of various materialized means used in the educational process. From the most basic blackboard, chalk, text teaching materials, teaching AIDS, projectors, slide projectors, televisions, wired and wireless public address systems, video display tables to multimedia computers; CAW closed-circuit television teaching network system and computer bidirectional transmission interactive network system are both hardware components of educational technology.

2. Educational technology is a carefully selected and reasonably organized learning textbook. These learning materials should not only meet the needs of society and students' personal learning, but also conform to the cognitive laws and be suitable for students' learning. This is a software component of educational technology.

3. Educational technology is also a method to design, implement and evaluate the teaching process. Such as Comenius' intuitive teaching method, Herbart's four-stage teaching method and the heuristic teaching method advocated by Confucius, an ancient educator in China. This is also an integral part of educational technology.

Therefore, the system composed of hardware, software and teaching methods is a complete concept of educational technology. In other words, educational technology is a system composed of teaching hardware, software and teaching methods.
