Jean Piaget
Stages of Cognitive Development
His theory
Jean Piaget believed that children didn't learn just from their parents or teachers, they could teach themselves. His theory is in stages that are throughout your life. The sensorimotor stage is from birth to age 2. From age 2-7 we are in the pre-operational stage. When we are in the ages 7-11 we are in the concrete operational stage. The formal operational stage begins in the adolescent years into the adult years.
