The development of educational technology in China mainly includes the formation and development of audio-visual education and the all-round development of audio-visual education to educational technology after the reform and opening up. Educational technology, as a new field of practice and research, began with the audio-visual education movement in the United States, and was marked by the appearance of audio-visual education in China.
At the beginning of the 20th century, slides were introduced into China, and the earliest silent film and slide show education methods began. With the development of foreign audio-visual education, the concept of audio-visual education was introduced to China in 1930s, which attracted the attention of the government education departments and scholars at that time and established the name of "audio-visual education".
From 65438 to 0936, the Ministry of Education established the Film Education Committee and the Broadcasting Education Committee in Nanjing, which were the earliest audio-visual education institutions in China. Before liberation, the development of economy, education and science and technology was backward, and audio-visual education in China was sporadic, which was carried out in a few cities, schools and social educational institutions, but it was not widely implemented.
After the founding of People's Republic of China (PRC), audio-visual education developed rapidly, and TV universities and radio correspondence universities were established in Beijing, Tianjin, Shanghai and Guangzhou. Until 1965, the audio-visual education in China has made great achievements and developed rapidly.
