The correct answer is ''actively construct their own cognitive worlds''

Explanation:

The theory of cognitive development of the Swiss psychologist Jean Piaget (1896-1980), explains how children build a mental model of the world. Piaget was one of the first theorists of constructivism in psychology. He believed that children actively build knowledge of the environment using what they already know and interpreting new facts and objects. Piaget's research focused primarily on the way in which they acquire knowledge as they develop. In other words, he was not so interested in what the child knows, but in how he thinks about problems and solutions. He was convinced that cognitive development involves changes in the child's ability to reason about his world.
