There are two definitions of education: broad and narrow. Education in a broad sense refers to all social practice activities to spread and learn the achievements of human civilization-all kinds of knowledge, skills and social life experience to promote individual socialization and social individualization, which originated from the primary stage of human society; Education in a narrow sense refers to school education, that is, institutionalized education.

Educational technology includes two aspects: understanding the needs of technology and educational technology. Technology in education refers to materialized technology, which is reflected by the educational media itself; Educational technology refers to the immaterial ability of educational methods and skills.

As for the relationship between the two, in a word-to achieve the purpose of education, we must use appropriate educational technology before and after the educational process, and educational technology is the premise to realize educational behavior and purpose.
