Piaget's View on Child Learning
Piaget concluded that babies aren't just born in possession of adult knowledge, either from a past life or from DNA. Instead, Piaget thought that children must have powerful learning mechanisms that allow them to construct new pictures of the world, pictures that might be very different from the adult picture. When we learn about the world, when we do science. for example, we don't just hit the right answer once and for all. Rather, there is a very gradual unfolding sequence of corrected errors, expanded ideas, and revised misconceptions as we approach more and more nearly to the truth. That was what the Piagets saw as they watched their babies make their way through infancy.
But Piaget also thought that learning was just as rooted in biology as any innate idea in the genetic code. He often used the metaphor of digestion: babies' minds assimilated information the way babies' bodies assimilated milk. For Piaget, learning was as natural as eating. This idea is the second element in the new developmental science.
Learning is natural, innate.
Children are like scientists, innately capable of understanding the world through experimentation, they also may have in-built mechanisms for learning language.
