The purpose of observing children is to better invest in early childhood education.

Observation is a purposeful and planned investigation of preschool children's performance in daily life, games, study and work, which mainly includes children's words, expressions and behaviors, and can analyze the laws and characteristics of children's psychological development. Teachers are good at discovering the educational value of things, games and accidents that children are interested in, seizing opportunities and actively guiding children. Teachers are usually supporters, collaborators and guides of children's learning activities. Parents should also be children's listeners and observers, which helps to understand children's growth level and learning ability, their emotional needs and experiences, and guide and cultivate sports.

It is usually necessary to understand children's current learning and development, evaluate their needs, expand their experience and promote their learning and development.
