Mixed-age education will give children a living environment for interacting with peers of different ages. In such an environment, older children can show themselves by getting along with younger children, learn to care about others and be able to give love. Younger children can grow up from older children, which will help them improve themselves. Early childhood is a critical period for children's social development. Mixed-age classes can make children's interpersonal skills grow, especially for only children.

In order to promote students' language development, older children generally have more English vocabulary than younger children in mixed-age classes because of differences in age and personal behavior. When they communicate with each other, younger children can gain better language expression and logical thinking ability under the influence of these "advanced English vocabulary"; Older children may become more and more easygoing. Therefore, in mixed-age classes, children's language expression ability will show a better development trend. To promote children's cognitive development, the key teaching methods for children are imitation, imitation of parents, imitation of teachers and imitation of people around them. In mixed-age classes, younger children will let older children imitate their behavior, thus learning each other's way of thinking invisibly and improving their cognitive development.

In order to satisfy their social desires, everyone has that feeling. When children are young, everyone takes them out. Younger children like to play with older children. Because following older children, children can gain a lot of new ways to play, but older children sometimes don't like to play with younger children. The mixed supervisor has brought this pure natural benefit to the children. With middle-class children communicating with them, they can get the care and care of middle-class brothers and sisters. I still remember very clearly that when Zheng went to be a mixed prison, he once went home to be a teacher and performed crossword puzzles with us, which was endless. At that time, I thought that the kindergarten teacher taught the children. I didn't expect to know that she and the children in the middle class were studying in the process of chatting with the kindergarten teacher, and the communication between the children was also very interesting.
