Piaget's theory of cognitive development represents constructivism, a view of cognitive development as a process in which people actively build systems of meaning and understandings of reality through their experiences and interactions.

This is a true statement. Through constructivism, a person "constructs" a meaning for their existence through how they interact with others and what those interactions entail. By doing so, they build a reality that is all their own, and can differ markedly from the experiences and beliefs of others.
