The hierarchical structure of preschool children's science education can also be called vertical structure. The goal of preschool children's science education can generally be divided into four levels from top to bottom according to its levels. That is, it is divided into four levels: the overall goal, the age stage goal, the unit goal and the activity goal of preschool children's science education. The overall goal, age stage goal, unit goal and activity goal are expounded respectively.

According to the classification of medicine and psychology at home and abroad, people can be divided into the following stages from birth to infancy: birth and newborn: birth-1 month; Infant: 1 month-1 year, equivalent to lactation; Toddler hood: 1-2 years old; Early childhood: 2-6 years old, equivalent to early childhood. Although this classification is being challenged day by day, especially the classification of infants is still inconclusive.

However, these stages are usually collectively referred to as childhood, that is, children before entering the primary school stage are collectively referred to as preschool children.

Concept:

Educational goal refers to the standard that the trained talents should reach. This goal can be high or low according to needs (the educational goal is to cultivate people's direction and specifications). It is a concrete and visible change (or progress) that reflects the purpose of education. There are many ways to classify educational goals. In order to compile the test, b·S· Bloom, a famous American psychologist, divided the educational goal into cognitive field, emotional field and motor skill field.

People's growth has laws to follow, which is a science about people themselves. Unfortunately, most people care about all kinds of science, physics, biology, chemistry and computer science created by people, but they don't care much about human science. However, when we become parents and teachers, we must understand the law of human development, so as to raise children and train the next generation.

As parents, we really don't know much about human science. Of course, we don't need to be as proficient as human scientists. We need an idea: everything has a time. Everything has its own time
