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. ?
American educational technology was the earliest, developed clearly and completely, and had the greatest influence in the world. Other countries, such as Japan, Britain, Canada, etc., have borrowed the theoretical model of American educational technology, so the United States can be a typical representative of studying the development history of foreign educational technology. The formation and development of American educational technology can be traced back to three main aspects: first, the promotion of audio-visual teaching movement; The second is the promotion of personalized teaching; The third is the development of teaching system and methods.
Characteristics of educational technology:
Educational technology is not the general application of a certain teaching method, it includes the theory and practice of three concepts (learner-centered, relying on resources and using systematic methods) that are comprehensively applied to education and teaching. Educational technology attaches importance to the analysis and study of learners' characteristics (such as behavior level, ability, knowledge base, age characteristics, etc.). ), because the learner's situation has a direct impact on many educational decisions such as choosing goals, determining the rhythm, and determining the nature of evaluation.
In educational technology, solving problems depends on developing and utilizing learning resources, promoting personalized learning and improving people's learning quality. Educational technology attaches importance to the development, application, management, design and learners' learning experience of all learning resources or learning media called human beings, and emphasizes the scientific and systematic method to analyze and integrate the process of "teaching and learning".
