Answer:
Jean Piaget
Jean Piaget, a pioneer in the study of cognitive development in children, was able to show not only that young children think differently than adults, but also that individuals move through stages of learning development that increasingly become more complex. Each child, he believed, has a mental representation, or knowledge, of the world, which is called a schema. As children develop, they acquire new information through assimilation, when an existing schema is able to deal with a new object, or idea, or accommodation, when the schema must change to deal with the new idea or object. Throughout one's lifetime, Piaget believed there are four stages of learning development, which include sensorimotor (infancy), preoperational (toddler-early childhood), concrete operational (elementary-early adolescence), and formal operational (adolescence-adulthood).
