Early education is an important link in cultivating children. Many facts have proved that early education can promote infants' intellectual development and lay a good foundation for their future development. Early education is to train the baby purposefully and step by step, and train him in all aspects, such as movement, language, cognition and social interaction, so as to give full play to his potential and lay a good foundation for his future growth. Research shows that the development of nervous system is in a leading position in all systems. The weight of newborn's brain is equivalent to 25% of that of adults, reaching about 75% of that of adults at the age of 3, and only a quarter of that of adults at the age of 3. This shows that 0 ~ 3 years old is the key period for the rapid proliferation of brain cells and the maturation of nerve fiber myelin sheath, and the speed of brain development during this period will directly affect the intellectual development of infants. Every subject has its specific research object, and pedagogy is no exception. It is a science that studies this social phenomenon and prompts its laws. There are many branches of pedagogy, and early education is one of them. ? Early education refers to the education in infancy and infancy. It refers to the activities that educators consciously and purposefully influence children according to their physical, mental and intellectual development characteristics, so that they can acquire necessary knowledge and life skills and promote their physical, mental and psychological development. The main bodies of early education are families and kindergartens, as well as service institutions specializing in early childhood education. ? According to the definition of American Early Childhood Education Association, early education refers to the education of children aged 0 to 8. In some cases, early education refers to the education of children aged 0 to 3 or preschool children. For example, current research proves that early education has short-term or long-term effects on brain and cognitive development. Studies have shown that from infancy to 10 years old, brain cells not only form connections, but also have the greatest adaptability during this period, that is, they can change the structure of the brain through active brain stimulation. ?
