A: Education is a social activity to cultivate people, which is closely related to social development and human development. Broadly speaking, all activities that enhance people's knowledge and skills and affect people's ideology and morality are education. Education in a narrow sense mainly refers to school education, which means that educators exert purposeful, planned and organized influence on the body and mind of the educated according to the requirements of a certain society (or class) and cultivate people needed by a certain society (or class). Generally speaking, from the difference between education and other social phenomena, education is a purposeful social activity to cultivate people. All activities that purposefully improve people's knowledge and skills, affect people's ideology and morality, and improve people's physique are education in the broadest sense. Education in a broad sense also includes various purposeful influences of society, family and school on people. In other words, education in a broad sense includes both institutionalized education and non-institutionalized education, which is the floorboard of all education. Narrow education, corresponding to broad education, mainly refers to institutionalized education, that is, school education at all levels. Today, the concept of school education is no longer just primary and secondary education and general higher education. Today's correspondence education, radio and television education, all kinds of vocational education and multimedia distance teaching also have the nature of school education and are institutionalized education.
