Jean Piaget was a Swiss psychologist known for his theory of cognitive development. He proposed that children's thinking develops through four stages - sensorimotor, preoperational, concrete operational, and formal operational - as their brains mature. At each stage, children understand and experience the world differently. Piaget's theory emphasized that children are not just empty vessels to be filled with knowledge, but rather they actively construct their own understanding through hands-on experiences with objects and interactions with others. His work revolutionized the field of developmental psychology and still influences modern education.

2. Jean Piaget’s Theory

3. Jean Piaget
(August 9, 1896 – September 16, 1980)
• Born in Neuchâtel in the French-speaking part
of Switzerland.
• Natural scientist and developmental
psychologist well known for his work studying
children and his theory of cognitive
development.

4. Jean Piaget
• His career of scientific research began when he
was just eleven, with the 1907 publication of a
short paper on the albino sparrow.
• Wrote more than sixty books and several
hundred articles.

5. Jean Piaget
• In 1923, he married Valentine Châtenay, the
couple had three children, whom Piaget studied
from infancy.
• Began to explore children in Alfred’s Binet
Laboratory. This is where the Modern Test of
Intelligence was created.

7. Theory
• Piaget proposed the theory of childhood
cognitive development in 1969.
• Cognitive Development is the combine
result between the maturity of the brain and
nervous system with the environment
adjustments.

8. Theory
• Children’s logic and modes of thinking are
initially entirely different from those of
adults.
• Piaget’s view is constructivist.

9. Theory
• Terms that describe the dynamic of
development:
• Schemes
• Adaptation
• Assimilation
• Accommodation
• Equilibrium

10. Theoretical Implications
• Piaget believed children’s schemes, or
logical mental structures, change with age
and are initially action-based (sensorimotor)
and later move to a mental (operational)
level.
• Children’s cognitive performance is directly
related to the stage they are in, he proposed
four major stages of development.

11. Theoretical Implications
Cognitive Development Stages
• The Sensorimotor Period (birth to 2 years)
• Preoperational Thought (2 to 6/7 years)
• Concrete Operations (6/7 to 11/12 years)
• Formal Operations Formal Operations (11/12 to
adult)

12. Cognitive Development Stages
The Sensorimotor Period (0-2 yrs.)
• Infants and toddlers "think" with their eyes,
ears, hands, and other sensorimotor
equipment.
• They learn to generalize their activities to a
wider range of situations and coordinate
them into increasingly lengthy chains of
behavior.

13. Cognitive Development Stages
Preoperational Thought (2-7 yrs.)
• Children acquire representational skills in
the area of mental imagery, and especially in
language.
• They are very self-oriented, and have an
egocentric view; that is, preoperational
children can use these representational
skills only to view the world from their own
perspective.

14. Cognitive Development Stages
Concrete Operations (7-11 yrs.)
• Children are able to take into account
another person’s point of view.
• They can represent transformations as well
as static situations.
• Children at this stage would have the ability
to pass conservation (numerical),
classification, serration, and spatial
reasoning tasks.

15. Cognitive Development Stages
Formal Operations (11- adult)
• Capable of thinking logically and abstractly.
• They can reason theoretically.
• The ultimate stage of development, and
stated that although the children would still
have to revise their knowledge base, their
way of thinking was as powerful as it would
get.

16. Contributions:
• Piaget made a revolution with the
developmental psychology concentrating all
his attention to the mental process and his
roll with behavior.
• He made us conscious with the way children
and adults think.

17. Contributions:
• Helped educators, parents, and
investigators to comprehend the capacity of
children in their different stages.
• A lot of school programs have been
redesigned taking as base Piaget’s
discoveries.
