There are graduate students in preschool education. Pre-school education majors train teachers, pre-school education administrators and teaching and research talents of other relevant institutions who have professional knowledge of pre-school education and can engage in teaching and research work in kindergartens. Preschool pedagogy is a young science. In the past 30 years, due to the development of science and technology and the social attention to preschool education, great progress has been made in the theoretical research of preschool education. Foreign scientific research achievements have further developed in the following aspects: for example, the role of preschool education in children's development, the important role of parents in children's education, and the development of children's language and cognition.
