Piaget Children Knowledge

Piaget investigated how children add up knowledge. The theory of cognitive development has two sides. First, are the key concepts of the theory and second, are the stages of development of cognition. The criticism directed to this theory was mainly its build up on qualitative research; however, the implications of Piaget theory in learning are many. This thesis briefly reviews Piaget’s cognitive development theory, support and criticism, and implications in the classroom.

Piaget’s cognitive development theory: Application in the classrooms

Jean Piaget’s chief interest was how humans add up knowledge, and the idea that what characterizes humans is the competence to grasp, intellectually, emblematic representative logical thinking. Many psychologists compared Piaget’s work with that of Lev Vygotsky, however, the work of Vygotsky focused mainly on the social interaction as the principle origin of knowledge (Huitt and Hummel, 2003). The aim of this thesis is to; briefly, review Piaget’s cognitive development theory, its key concepts, support, and criticism, and how teachers can apply it in the classrooms.

Piaget’s cognitive development theory and its key concepts

Piaget’s cognitive theory has two principle sides: first, how adding up knowledge occurs (process of cognition or key concepts of Piaget’s theory). Second, what are the stages humans pass through to develop the ability to know (stages of cognitive development)?

A stage is a period of development in which the child can grasp the meaning of some things but not aware to other things. Piaget recognized four stages in cognitive development.

A) From birth to two years old, sensorimotor stage: The infant builds up a collection of simple ideas about all what exists and happens through physical collaboration reciprocal actions with the surroundings. In this stage, knowledge is limited yet developing, and the infant acquires awareness of objects (object permanence).

B) Toddler and early childhood (2-7 years), preoperational stage: The child is not able to imagine non-presentational ideas and still needs real physical situations.

C) Early adolescence (7-11 years), concrete operational stage: The process of working something related especially to volume, weight, length, or number develops. The notion of the child is the center of every thing around diminishes.

D) Adolescence and adulthood (starting at 11-15 years), Formal operational stage: In this stage, cognitive structure is near or the same as that of an adult and is characterized by abstract theoretical logic.

Support and criticism to Piaget’s cognitive development theory

Criticism to Piaget’s cognitive theory focused on three main points first is Piaget’s research methods were only descriptive case studies. Second, is the disagreement that all children instinctively go from one stage to the next particularly in the formal operational stage. Third criticism is the theory undervalues the some children’s competence at the age of 4-7 years when they may show some complex schema (Huitt and Hummel, 2003). On the other hand, Lourenqo and Machado, 1996, defended Piaget’s theory and claimed that criticism come from misunderstanding of the theory, and ignoring Piaget’s modifications of the theory after 1970. They also claimed that whoever criticized Piaget’s theory did not consider the discussion of the case studies, despite being theoretical. Lourenqo and Machado, 1996, assumed that although discussions around Piaget’s theory may not end in the future, yet there are important viewpoints in theory that have not been integrated by psychologists.

Piaget cognitive theory: Application in the classroom

According to the key concepts and stages of cognitive development by Piaget, disclosing inventive learning and supporting the child’s growing abilities and attentions are the two main teaching techniques required.

The implications of Piaget’s theory for learning are many, the most important of which are five issues as suggested by Webb, 1980.

Huitt, 1997, designed application examples of teaching based on stages of cognitive development. For second stage preoperational child, Huitt suggested use of visual aids, relatively short instructions, giving these children a chance for physical practice, support to handling objects. Huitt also, suggested the provision of chances to explore the world (discussions on what they watched on TV, field trips…etc). For third stage children (middle childhood), Huitt suggested to continue giving children chances to handle object and continue the use of visual aids. In addition, better organization of lectures; use often-encountered examples to explain complex concepts and present problem, which require reasoning. For adolescents, Huitt suggested to constantly ask students how they solved their problems and whenever feasible, explain broader ideas and not just facts.

Conclusion

Although Piaget did not apply his theory to education, yet, qualitative cognitive development has an impact on learning. Many educational programs centered on the notion that a child should learn at the level he or she is developmentally prepared. Learning strategies deduced from Piaget theory a class environment that supports cognition development and the role of classmates and colleagues teaching to make use of social interaction in acquiring better perception and self-awareness.
