It was originated by the Swiss developmental psychologist Jean Piaget (1896–1980). The theory deals with the nature of knowledge itself and how humans gradually come to acquire, construct, and use it. [1] Piaget's theory is mainly known as a developmental stage theory.
Piaget specified that knowledge cannot truly be formed until the learner has matured the mental structures to which that learning is specific, and thereby development constrains learning. Nevertheless, knowledge can also be "built" by building on simpler operations and structures that have already been formed.
Jean Piaget was a major force establishing this field, forming his "theory of cognitive development". Piaget proposed four stages of cognitive development: the sensorimotor, preoperational, concrete operational, and formal operational period. [2] Many of Piaget's theoretical claims have since fallen out of favor.
Constructivism in education is rooted in epistemology, a theory of knowledge concerned with the logical categories of knowledge and its justification. [3] It acknowledges that learners bring prior knowledge and experiences shaped by their social and cultural environment and that learning is a process of students "constructing" knowledge based on their experiences.
Piaget proposes three types of knowledge: physical, logical mathematical, and social knowledge. Physical knowledge: It refers to knowledge related to objects in the world, which can be acquired through perceptual properties. The acquisition of physical knowledge has been equated with learning in Piaget's theory (Gruber and Voneche, 1995).
Learning was viewed as a phenomenon that can be directed and supported in institutions like schools. Another significant theory was Jean Piaget's constructivism, which described how learners construct knowledge by expanding and changing their ideas based on the information they receive.
Jean Piaget. Developmental psychologist, Jean Piaget, theorized that one's cognitive ability, or intelligence – defined as the ability to adapt to all aspects of reality – evolves through a series of four qualitatively distinct stages (the sensorimotor, pre-operational, concrete operational and formal operational stages). [5]
Jean Piaget's cognitive developmental theory describes four major stages from birth through puberty, the last of which starts at 12 years and has no terminating age: [11] Sensorimotor: (birth to 2 years), Preoperations: (2 to 7 years), Concrete operations: (7 to 11 years), and Formal Operations: (from 12 years). Each stage has at least two ...
