    Why did Piaget develop his theory?

    O conhecimento não é uma cópia da realidade. Conhecer um objeto, conhecer um acontecimento não é simplesmente olhar e fazer uma reprodução mental ou imagem do mesmo. Para conhecer um objeto é necessário agir sobre ele. Conhecer é usar, modificar, transformar esse objeto, e compreender o processo dessa transformação e, conseqüentemente, compreender o modo como o objeto é construído. Assim, a operação é que é a essência do conhecimento.

    Jean Piaget

    Jean Piaget was born in Neuchâtel (Switzerland) on August 9, 1896. He died in Geneva on September 16, 1980. He was the oldest child of Arthur Piaget, professor of medieval literature at the University, and of Rebecca Jackson. At age 11, while he was a pupil at Neuchâtel Latin high school, he wrote a short notice on an albino sparrow. This short paper is generally considered as the start of a brilliant scientific career made of over sixty books and several hundred articles.

    Piaget has been labeled an interactionist as well as a constructivist. His interest in cognitive development came from his training in the natural sciences and his interest in epistemology. Piaget was very interested in knowledge and how children come to know their world. He developed his cognitive theory by actually observing children (some of whom were his own children). Using a standard question or set of questions as a starting point, he followed the child's train of thought and allowed the questioning to be flexible. Piaget believed that children's spontaneous comments provided valuable clues to understanding their thinking. He was not interested in a right or wrong answer, but rather what forms of logic and reasoning the child used (Singer, 1978). After many years of observation, Piaget concluded that intellectual development is the result of the interaction of hereditary and environmental factors. As the child develops and constantly interacts with the world around him, knowledge is invented and reinvented. His theory of intellectual development is strongly grounded in the biological sciences. He saw cognitive growth as an extension of biological growth and as being governed by the same laws and principles (London, 1988). He argued that intellectual development controlled every other aspect of development - emotional, social, and moral.

    Stages of Intellectual Development

    Piaget may be best known for his stages of cognitive development. Piaget discovered that children think and reason differently at different periods in their lives. He believed that everyone passed through an invariant sequence of four qualitatively distinct stages. Invariant means that a person cannot skip stages or reorder them. Although every normal child passes through the stages in exactly the same order, there is some variability in the ages at which children attain each stage. The four stages are: sensorimotor - birth to 2 years; preoperational - 2 years to 7 years; concrete operational - 7 years to 11 years; and formal operational (abstract thinking) - 11 years and up. Each stage has major cognitive tasks which must be accomplished. In the sensorimotor stage, the mental structures are mainly concerned with the mastery of concrete objects. The mastery of symbols takes place in the preoperational stage, when children begin to think symbolically and learn to use words and develop language as a tool for thinking. In the concrete stage, children learn mastery of classes, relations, and numbers and how to reason. The last stage deals with the mastery of thought (Evans, 1973).


    How children learn

    ...we discovered that education is not something which the teacher does, but that it is a natural process which develops spontaneously in the human being. It is not acquired by listening to words, but in virtue of experiences in which the child acts on his environment. The teacher's task is not to talk, but to prepare and arrange a series of motives for cultural activity in a special environment made for the child.

    A central component of Piaget's developmental theory of learning and thinking is that both involve the participation of the learner. Knowledge is not merely transmitted verbally but must be constructed and reconstructed by the learner. Piaget asserted that for a child to know and construct knowledge of the world, the child must act on objects and it is this action which provides knowledge of those objects (Sigel, 1977); the mind organizes reality and acts upon it. The learner must be active; he is not a vessel to be filled with facts. Piaget's approach to learning is a readiness approach. Readiness approaches in developmental psychology emphasize that children cannot learn something until maturation gives them certain prerequisites (Brainerd, 1978). The ability to learn any cognitive content is always related to their stage of intellectual development. Children who are at a certain stage cannot be taught the concepts of a higher stage.


    Intellectual growth involves three fundamental processes: assimilation, accommodation, and equilibration. Assimilation involves the incorporation of new events into preexisting cognitive structures. Accommodation means existing structures change to accommodate to the new information. This dual process, assimilation-accommodation, enables the child to form schema. Equilibration involves the person striking a balance between himself and the environment, between assimilation and accomodation. When a child experiences a new event, disequilibrium sets in until he is able to assimilate and accommodate the new information and thus attain equilibrium. There are many types of equilibrium between assimilation and accomodation that vary with the levels of development and the problems to be solved. For Piaget, equilibration is the major factor in explaining why some children advance more quickly in the development of logical intelligence than do others (Lavatelli, 40).

    Implications for education

    A Piagetian-inspired curricula emphasizes a learner-centered educational philosophy. The teaching methods which most American school children are familiar with - teacher lectures, demonstrations, audio-visual presentations, teaching machines, and programmed instruction - do not fit in with Piaget's ideas on the acquisition of knowledge. Piaget espoused active discovery learning environments in our schools. Intelligence grows through the twin processes of assimilation and accomodation; therefore, experiences should be planned to allow opportunities for assimilation and accomodation. Children need to explore, to manipulate, to experiment, to question, and to search out answers for themselves - activity is essential. However, this does not mean that children should be allowed to do whatever they want. So what is the role of the teacher? Teachers should be able to assess the child's present cognitive level; their strengths and weaknesses. Instruction should be individualized as much as possible and children should have opportunities to communicate with one another, to argue and debate issues. He saw teachers as facilitators of knowledge - they are there to guide and stimulate the students. Allow children to make mistakes and learn from them. Learning is much more meaningful if the child is allowed to experiment on his own rather than listening to the teacher lecture. The teacher should present students with materials and situations and occasions that allow them to discover new learning. In his book To Understand Is to Invent Piaget said the basic principle of active methods can be expressed as follows: "to understand is to discover, or reconstruct by rediscovery, and such conditions must be complied with if in the future individuals are to be formed who are capable of production and creativity and not simply repetition" (p.20). In active learning, the teacher must have confidence in the child's ability to learn on his own.

    Implications for Instructional Technology

    Laboratories, workshops and technologies that encourage interactivity such as multimedia, hypermedia and virtual reality fit in with Piagetian thought. Computer software that is strictly drill and practice does not fit in with an active discovery environment. Drill and memorization practice, often used in language schools, do not encourage creativity or discovery.

    Students not only can use multimedia to learn, but they can also use it to communicate their understanding of the subject to those around them. They can create what they learn by using an authoring tool such as Hypercard. Peer teaching is used as the students work together in the making of their projects. Students become active participants instead of passive sponges and the teacher truly takes on the role of facilitator as she gives them guidance in their creations. Hypermedia also allows the students to manipulate their environment as they follow the path(s) of their choice. Virtual reality has the potential to move education from its reliance on books to experential learning in naturalistic settings. For example, rather than reading about an event, the children can participate in the event with simulated persons and/or objects. These technologies supply the students with a learning environment that encourages children to initiate and complete their own activities.

    What inspired Piaget?

    Much of Piaget's childhood was influenced by what he saw in his father, a man intensely dedicated to his studies and work. Because of this, at an early age Piaget began passing up recreation for studying, particularly the study of the natural sciences.

    When did Piaget develop his theory of cognitive development?

    His theory of intellectual or cognitive development, published in 1936, is still used today in some branches of education and psychology. It focuses on children, from birth through adolescence, and characterizes different stages of development, including: language. morals.

    How did Piaget develop theory?

    His theories came from observing children and recording their development. He brought attention to the idea that children are not just small adults, and he argued that the way they think is fundamentally different.

    What is the purpose of Piaget's cognitive development?

    To Piaget, cognitive development was a progressive reorganization of mental processes as a result of biological maturation and environmental experience. Children construct an understanding of the world around them, then experience discrepancies between what they already know and what they discover in their environment.
