Lesson 1: The Principles of Learning
7 - The Basic Theories of Piaget
Jean Piaget was a famous Swiss psychologist who gained worldwide recognition for his studies of the thought processes of children. Piaget outlined four principle stages of concept formation. Concept refers to the meaning an individual gives to various objects or abstract ideas. Concept formation refers to the way we build these ideas in our mind. You can picture concept formation as like the process a child goes through when assembling interlocking blocks to make various shapes and structures.
The following important principles were described by Piaget when discussing concept formation:
    • Each stage must occur in proper sequence.
     • A child cannot attempt a more difficult skill until mastering the skills at a lower level.
     • Each stage is cumulative; earlier skills are retained and are the basics for reaching the next higher level.
     • The child acquires skills gradually and in a systematic order.
 The ages suggested for Piaget’s four principle stages of concept formation are approximate.

Stage One - Sensorimotor
|
|
Approximate Age | Behaviour |
Birth to 1 month | Sucking reflex |
1 month to 6 months | Repetition of certain acts, e.g., opening and closing the hands or kicking the legs |
6 months to 11 months | Coordination of movements |
11 months to 18 months | Solutions to problems are sought |
During the sensorimotor stage, babies learn through physical contact with their surroundings by using their senses. They acquire a basic idea of cause and effect. For example, if they push the ball, it will roll across the room.

Stage Two - Pre-operational
|
|
Approximate Age | Behaviour |
18 months to 4 years | Self-centredness is replaced by more emphasis on social interaction |
4 years to 7 years | Centration and Decentration - focuses on the main features of an object, but also accounts for other important details |

Stage Three - Concrete Operational
|
|
Approximate Age | Behaviour |
7 years to 11 years | Emphasizes what is real |
Space corrector
Stage Four - Formal Operational
|
Approximate Age | Behaviour |
11 years to 15 years | Thought is given to what is possible |
Young people are now comfortable in dealing with abstract concepts. Abstract concepts are ideas about objects that are viewed separately or apart from the physical object. A concrete concept is a doghouse; an abstract concept is religious freedom.
