Piaget's theory of cognitive development describes how human intelligence develops in a series of stages from infancy to adulthood. The stages are sensorimotor (birth to age 2), preoperational (ages 2 to 7), concrete operational (ages 7 to 11), and formal operational (ages 11 to adulthood). At each stage, children construct an understanding of the world through interactions with objects and people. Piaget believed that cognitive development relies on biological maturation and active learning through discovery rather than passive absorption.
2. “Knowledge is the ability to
modify, transform, and
operate on an object, or
idea, such that it is
understood by the operator
through the process of
transformation.”
Jean Piaget (1896-1980)
3. Piaget’s theory of cognitive development is about the
nature and development of human intelligence.

4. • Schemas (building blocks of knowledge)
• Adaptation processes that enable the transition from one
stage to another (equilibrium, assimilation,
accommodation).
• Stages of development
• Sensorimotor
• Preoperational
• Concrete operational
• Formal operational
6. Piaget viewed intellectual growth as a process of
adaptation (adjustment) to the world. This happens
through:
Assimilation
Using an existing
schema to deal
with a new
object/situation
Accommodati
on
When the existing
schema does not
work, and needs
to be changed to
deal with new
object/situation
Equilibration

Disequilibrium

(e.g. teaching children geometric figures)
8. According to Piaget, assimilation and accommodation
require an active learner, not a passive one, because
problem-solving skills cannot be taught, they must be
discovered.
Teachers should facilitate learning and encourage the
following within the classroom:
• Focus on the process of learning, rather than the end
product of it.
• Using active methods that require rediscovering or
reconstructing “truths”.
9. • Using collaborative, as well as individual activities.
• Devising situations that present useful problems, and
create disequilibrium in the child.
• Evaluate the level of the child’s development, so suitable
tasks can be set.
10.
11. This stage extends from birth to the acquisition of
language.
In this stage, infants progressively construct knowledge
and understanding of the world by coordinating
experiences (such as vision and hearing) with physical
interactions with objects (such as grasping, sucking, and
stepping).

birth

thought
12. Coordination of sensation and action through reflexive
behaviours.
• Sucking of objects in mouth
• Following moving or interesting objects with the eyes.
• Closing of the hand when an object makes contact with
the palm (palmar grasp).
13. Coordination of sensation and two types of schema: habits
(reflex) and primary circular reactions (reproduction of an
event that initially occurred by chance).
At this phase, passive reactions, caused by classical or
operant conditioning, can begin.
14. Development of habits. Infants become more object-
oriented, moving beyond self-preoccupation; repeat actions
that bring interesting or pleasurable results. (vision and
prehension)
Intentional grasping for a desired object.
Repetition of an act involving external objects.
Differentiation between means and ends.
15. Coordination of vision and touch – hand-eye coordination;
coordination of schemas and intentionality.
Development of logic
First proper intelligence
Goal orientation
16. Infants become intrigued by the many properties of objects
and by the many things they can make happen to objects;
they experiment with new behaviour.
Discovery of new means to meet goals.
17. Infants develop the ability to use primitive symbols and
form enduring mental representations.
Beginning of insight, or true creativity.
By the end of the sensorimotor period, the child sees
objects as both separate from the self, and permanent.
18. This stage starts when the child begins to learn to speak at
age two and lasts up until the age of seven.

21. This stage occurs between the ages of seven to eleven
years, and is characterized by the appropriate use of logic.
• Ability to distinguish between their own thoughts and the
thoughts of others.
• Increased classification skills.
• Ability to think logically about objects and events.
• Ability to fluently perform mathematical problems in both
addition and subtraction.
22. Classification
This is the ability to name and identify
sets of objects according to
appearance, size or other
characteristic, including the idea that
one set of objects can include
24. The child now takes into
account multiple aspects of a
problem to solve it.
25. The child now understands that numbers or
objects can be changed and then returned to their
original state.
26. The ability to sort
objects in order
according to size,
shape, or any
other
characteristic.
27. Transitivity refers to the ability to mentally
sort objects and recognize relationships
among various things in a serial order.
28. This stage is from adolescence to adulthood, roughly ages
11 to approximately 15-20.

29. Piaget believed in two basic principles relating to moral
education:
• Children develop moral ideas in stages
• Children create their conceptions of the world
30. • It is concerned with children, rather than all learners.
• It focuses on development, rather than learning per se,
so it does not address learning of information or specific
behaviors.
31. • Teachers can use Piaget’s theory when discussing
whether the syllabus subjects are suitable for the level of
students or not.
• Teachers can adopt appropriate academic expectations
with regard to children’s cognitive developmental abilities.
32. “Education, for most
people, means trying to
lead the child to resemble
the typical adult of his
society… but for me and
no one else, education
means making creators…
You have to make
inventors, innovators – not
conformists.” (Bringuier,
1980, p.132)
