With the rapid development of social science and technology, more and more parents begin to pay attention to children's teaching, and preschool education plays an increasingly important role in educational development. However, many parents have some problems in their cognition of preschool education, which lacks systematicness and scientificalness. They think that preschool education is to advance the knowledge to be learned in primary schools and master more primary school knowledge in kindergartens. Parents fail to establish a correct concept of quality-oriented education and neglect the comprehensive and healthy development of children, which leads to the difficulty of forming a harmonious teaching atmosphere in kindergartens and implementing preschool education activities to a certain extent.
