Step-by-step explanation:
The theorist who states that learning is an active process of construction rather than passive assimilation of information/rote memorization is A. Piaget. Piaget's cognitive theory of development focuses on children's cognitive growth and emphasizes that our cognitive abilities develop through specific stages. He believed that thinking is a central aspect of development and that children are naturally inquisitive. According to Piaget, children do not think and reason like adults, and there is a distinct shift in how we think and reason as we progress to a new stage of development.
