Piaget referred to the Theory of Assimilation to describe children who utilized the acts of incorporating objects, or some aspect of objects into information or phenomena they had already learned. The theory of Accommodation was coined to describe children who were able to take new information, and save it because it was relevant to all information or disregard the information because it had no relevance (Anderson, Belgrave, Lane, & Michalek (n. d.).

Later, with the two theories, Piaget added theories of cognitive development. According to Anderson et al., Piaget hypothesized that children had four stages of learning: (a) sensorimotor motor stage, (b) Preoperational, (c) concrete, and formal operations. (a) Sensorimotor stage [birth to age 2], (b) preoperational stage [ages 2 to 7 years], (c) concrete operations [7 to 11), and (d) formal operations stage [12-adulthood]. All four stages are representative of scientific characteristics through which the child will progress. For example, during the sensorimotor stage, the child understands the physical environment and the concept of how his or her environment works (however the child does not understand that physical ...
