Piaget's phase concept explains the cognitive development of children. Cognitive development involves a transformation of cognitive process and skills. In Piaget's view, initial cognitive development involves measurement-based processes and then continues with changes in brain operations. Diagrams; a diagram clarifies both the brain and physical actions involved in understanding and knowing. Schemas are kinds of information that help us explain and understand the world. In Piaget's view, a schema includes both a group of understanding and the procedure for acquiring that knowledge. As practice progresses, this new information is used to adapt, complete or modify the diagrams previously presented. For example, a child may have a schema about a type of animal, such as a dog. If the child's only experience has been with small dogs, he might consider that all dogs are small, furry, and have 4 legs. Then suppose the child comes across a very large dog. The child will integrate this new information, modifying the previously existing schema to include this new information. Assimilation; the process of integrating new information into our prior existing schemas is known as assimilation. Development is rather subjective, as we tend to modify experience or information to some extent to fit our pre-existing values. In the example above, seeing a dog and labeling it "dog" is a good example of assimilating the animal into the child's canine schema. Accommodation; Another division of adaptation involves changing or modifying our existing schemas in light of new information, a method recognized as accommodation. Accommodation involves the modification of existing patterns or thoughts, therefore new information or new experiences. New sc...... middle of paper ......of mental operations. Children begin to think logically about concrete events, but have difficulty understanding abstract or hypothetical concepts. Piaget determined that children in the concrete operational phase were quite good at using inductive logic. Inductive logic involves moving from a specific experience to a general principle. On the other hand, children this age have difficulty using deductive logic, which involves using a general principle to decide the outcome of a specific event. One of the most important developments at this stage is the understanding of reversibility, or the awareness that actions can be reversed. An example of this is the ability to reverse the order of relationships between mental categories. For example, a child might be able to recognize that their dog is a Labrador, that a Labrador is a dog, and that a dog is an animal..
