Explain how children construct knowledge according to Piaget?

According to Piaget's theory of cognitive development, children construct knowledge through a process of assimilation and accommodation.

Assimilation is the process by which children incorporate new information into their existing mental structures or schemas. For example, a child may already have a schema for a dog, and when they encounter a new animal that fits that schema, they assimilate it as a dog.

Accommodation, on the other hand, is the process by which children modify their existing schemas to incorporate new information that does not fit their existing mental structures. For example, if a child encounters a cat for the first time and realizes it is different from a dog, they may need to create a new schema for cats.

Through a process of assimilation and accommodation, children gradually build and refine their mental structures, allowing them to understand and interact with the world around them in more complex and sophisticated ways. Piaget believed that children actively construct their own knowledge through their interactions with the environment, rather than passively receiving information from adults or other sources.
