Piaget developed his theory about cognitive development during the 1930s in Switzerland. He focused on three main ideas: schemas, adaptation processes, as well as stages of cognitive development. Schemas, according to Piaget are basically the “building blocks” of knowledge. “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” (McLeod, 2018a). Adaptation processes facilitate the progression from one phase to the next. This would be movement from equilibrium to assimilation and assimilation to accommodation. But in the case where a specific schema may not fit into a new circumstance, the child must regain equilibrium by assimilating, and finally accommodating. The stages Piaget referred to pertaining cognitive development are 1) Sensorimotor, 2) Preoperational, 3) Concrete Operational, and 4) Formal Operational (McLeod, 2018). Piaget’s theory is important because it can provide meaningful insight to educators and even other professionals concerning the learning processes entailed in both the school setting and the workplace.
