Piaget's theory.
Piaget believed that cognitive development occurs
through the interaction of innate capacities and
environmental events, that proceed through a

Piaget believed in the key terms and often used
them to describe how and why children learn

Concrete The child's use of logic improves and they can do

(7-11) irreversibility but cant yet use abstract reasoning
Formal Can use abstract reasoning in problem solving. Can also deal
operational stage with hypothetical situations

1. Piaget built a 3D model of three mountains
2. The mountains had different landmarks such as a
house and a big tree
3. They put a small doll on one of the mountains
and showed children pictures from different
4. The children were asked to pick a photo which
the DOLL could see
5. Piaget found that pre operation children picked

6. Therefore the children were unable to put
themselves in the doll's shoes.…read more
