We can use the example of a sink or float science experiment to demonstrate the presence of reversibility. In this experiment, the child places various objects in a bucket of water, testing to see if they float or sink. A child in the preoperational stage would be able to describe the procedure taken, but only a child in the concrete operational stage would be able to retell the experiment in various ways, such as chronologically or out of order.
Multi-step procedures are common in the classroom setting, which makes reversibility a valuable skill in learning. Children that are still in the preoperational stage may require assistance in activities in the form of prompts or reminders from the teacher.
We can use the task of learning vocabulary from a story as an example in the classroom. This type of multi-step instruction involves returning to the first and second tasks many times, which only children who have already reached the concrete operational stage are able to do. The second skill that is acquired is decentering. This allows the child to step back and analyze an issue from more than one angle.
Being able to consider a problem from another perspective is a key feature of the concrete operational stage. We can view the emergence of this ability in the preoperational stage when children start participating in dramatic play. For example, a child may use a banana as a pretend telephone, demonstrating an awareness that the banana is both a banana and a telephone. Piaget argued that children in the concrete operational stage are making more intentional and calculated choices, illustrating that they are conscious of their decentering.
An example in the classroom can be displayed in the form of a simple worksheet. Using a multi-step instruction, the teacher can ask students to identify all problems that fit two criteria: it is a two-digit subtraction problem and it requires regrouping. The child is only responsible for solving problems that fit both of those requirements.
A child in the concrete operational stage can move between the first and second criteria with ease, analyzing each problem to see if it meets both specifications. This task would also assume that the student is already able to regroup subtraction problems independently. Both reversibility and decentering tend to occur together in educational settings. As seen in the worksheet example, procedures may occur out of order while multiple criteria are in place.
Piaget had a popular example to demonstrate the idea of conservation or the idea that a quantity will remain the same despite the shape. He used two similar size balls of clay for his experiment. If one ball of clay were stretched thin like a hot dog, a child in the preoperational stage may state that they are different, even if the shape used the same amount of clay.
In the concrete operational stage, a child is able to understand that two different shapes can be made from the same volume of clay. As children move into the formal operational stage, they are able to reason about more abstract ideas.
Much like the concrete operational stage, the formal operational stage gets its name from the newly acquired skill of representing objects or events. In class, a teacher is now able to ask hypothetical questions with reasonable expectations.
Students must reflect internally on various ideas and manipulate many perspectives at once. Piaget called his collective theories on child development a "genetic epistemology.
Piaget died of unknown causes on September 16, , in Geneva, Switzerland. He was 84 years old. Piaget is responsible for developing entirely new fields of scientific study, having a major impact on the areas of cognitive theory and developmental psychology. Piaget was the recipient of an array of honorary degrees and accolades, including the prestigious Erasmus and Balzan prizes. The author of more than 50 books and hundreds of papers, Piaget summed up his passion for the ongoing pursuit of scientific knowledge with these words: "The current state of knowledge is a moment in history, changing just as rapidly as the state of knowledge in the past has ever changed and, in many instances, more rapidly.

Jean-Jacques Rousseau is best known as an influential 18th-century philosopher who wrote the acclaimed work 'A Discourse on the Arts and Sciences. Jean-Paul Sartre was a 20th century intellectual, writer and activist who put forth pioneering ideas on existentialism.
Carl Jung established analytical psychology. By 2 years, children have made some progress towards detaching their thought from physical world. However have not yet developed logical or 'operational' thought characteristic of later stages. Thinking is still intuitive based on subjective judgements about situations and egocentric centred on the child's own view of the world.
The stage is called concrete because children can think logically much more successfully if they can manipulate real concrete materials or pictures of them. Piaget considered the concrete stage a major turning point in the child's cognitive development because it marks the beginning of logical or operational thought. This means the child can work things out internally in their head rather than physically try things out in the real world.
Children can conserve number age 6 , mass age 7 , and weight age 9. Conservation is the understanding that something stays the same in quantity even though its appearance changes. But operational thought only effective here if child asked to reason about materials that are physically present.
Children at this stage will tend to make mistakes or be overwhelmed when asked to reason about abstract or hypothetical problems. From about 12 years children can follow the form of a logical argument without reference to its content. During this time, people develop the ability to think about abstract concepts, and logically test hypotheses. This stage sees emergence of scientific thinking, formulating abstract theories and hypotheses when faced with a problem.
Piaget's , theory of cognitive development explains how a child constructs a mental model of the world. He disagreed with the idea that intelligence was a fixed trait, and regarded cognitive development as a process which occurs due to biological maturation and interaction with the environment.
The goal of the theory is to explain the mechanisms and processes by which the infant, and then the child, develops into an individual who can reason and think using hypotheses. 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.
Piaget claimed that knowledge cannot simply emerge from sensory experience; some initial structure is necessary to make sense of the world. According to Piaget, children are born with a very basic mental structure genetically inherited and evolved on which all subsequent learning and knowledge are based.
Schemas are the basic building blocks of such cognitive models, and enable us to form a mental representation of the world. Piaget , p.
In more simple terms Piaget called the schema the basic building block of intelligent behavior — a way of organizing knowledge. Wadsworth suggests that schemata the plural of schema be thought of as 'index cards' filed in the brain, each one telling an individual how to react to incoming stimuli or information. When Piaget talked about the development of a person's mental processes, he was referring to increases in the number and complexity of the schemata that a person had learned.
When a child's existing schemas are capable of explaining what it can perceive around it, it is said to be in a state of equilibrium, i. Piaget emphasized the importance of schemas in cognitive development and described how they were developed or acquired.
A schema can be defined as a set of linked mental representations of the world, which we use both to understand and to respond to situations. The assumption is that we store these mental representations and apply them when needed. A person might have a schema about buying a meal in a restaurant. The schema is a stored form of the pattern of behavior which includes looking at a menu, ordering food, eating it and paying the bill. This is an example of a type of schema called a 'script.
The schemas Piaget described tend to be simpler than this - especially those used by infants. He described how - as a child gets older - his or her schemas become more numerous and elaborate. Piaget believed that newborn babies have a small number of innate schemas - even before they have had many opportunities to experience the world. These neonatal schemas are the cognitive structures underlying innate reflexes.
These reflexes are genetically programmed into us. For example, babies have a sucking reflex, which is triggered by something touching the baby's lips. A baby will suck a nipple, a comforter dummy , or a person's finger. Piaget, therefore, assumed that the baby has a 'sucking schema.
Similarly, the grasping reflex which is elicited when something touches the palm of a baby's hand, or the rooting reflex, in which a baby will turn its head towards something which touches its cheek, are innate schemas. Shaking a rattle would be the combination of two schemas, grasping and shaking.
Jean Piaget ; see also Wadsworth, viewed intellectual growth as a process of adaptation adjustment to the world. This happens through assimilation, accommodation, and equilibration.
Piaget defined assimilation as the cognitive process of fitting new information into existing cognitive schemas, perceptions, and understanding.
Overall beliefs and understanding of the world do not change as a result of the new information. This means that when you are faced with new information, you make sense of this information by referring to information you already have information processed and learned previously and try to fit the new information into the information you already have. For example, a 2-year-old child sees a man who is bald on top of his head and has long frizzy hair on the sides.
Psychologist Jean Piaget defined accommodation as the cognitive process of revising existing cognitive schemas, perceptions, and understanding so that new information can be incorporated. This happens when the existing schema knowledge does not work, and needs to be changed to deal with a new object or situation. In order to make sense of some new information, you actual adjust information you already have schemas you already have, etc.
For example, a child may have a schema for birds feathers, flying, etc. Piaget believed that all human thought seeks order and is uncomfortable with contradictions and inconsistencies in knowledge structures. In other words, we seek 'equilibrium' in our cognitive structures. Equilibrium occurs when a child's schemas can deal with most new information through assimilation.
However, an unpleasant state of disequilibrium occurs when new information cannot be fitted into existing schemas assimilation. Piaget believed that cognitive development did not progress at a steady rate, but rather in leaps and bounds. Equilibration is the force which drives the learning process as we do not like to be frustrated and will seek to restore balance by mastering the new challenge accommodation.
Once the new information is acquired the process of assimilation with the new schema will continue until the next time we need to make an adjustment to it.
Piaget did not explicitly relate his theory to education, although later researchers have explained how features of Piaget's theory can be applied to teaching and learning. Piaget has been extremely influential in developing educational policy and teaching practice. The result of this review led to the publication of the Plowden report Discovery learning — the idea that children learn best through doing and actively exploring - was seen as central to the transformation of the primary school curriculum.
