Piaget was born in Neuchâtel, in the Francophone region of Switzerland. He was born on August 9, 1896 and he died on September 16, 1980 at the age of 84. He was also known as constructivism, theory of cognitive development, object permanence, egocentrism and also a genetic epistemology, which is the study of knowledge. Piaget was a precocious child who developed an interest in biology and the natural world. In the 1920s Piaget observed children reasoning and understanding differently, depending on their age. He proposed that all children progress through a series of cognitive stages of development, just as they progress through a series of physical stages of development. Piaget introduced some important concepts which is the SCHEMA or SCHEMATA from the word prior knowledge, ASSIMILATION from previous concept down to new concept, ADAPTATION involves new information, EQUILIBRIUM is the search for “balance”.
According to Piaget, there are four stages that described his theory. First is the SENSORIMOTOR STAGE, from birth to 2 years of age. Second is the PREOPERATIONAL STAGE, from 4 to 7 years of age. Third is the CONCRETE OPERATIONAL STAGE, from 7 to 11 years of age. And last is the FORMAL OPERATIONAL STAGE, from 11 to 16 years of age, onwards.
As I was Piaget is widely considered to be the influential development psychologist in history. Because base from his theory it describes on how a child understand on what a teachers taught.
Piaget believed that cognitive development occurred in sequential distinct stages with abrupt improvement of skills from stage to stage. For example, children between the ages of 7-11 are in concrete operational stage. At this stage, they can use cognitive strategies to solve problems involving concrete objects. Elaboration and abstract thinking skills are to be developed as children get older, in the formal operational stage.
To be more specific, on Piaget’s theory describes that cognitive skills of one child
