Jean Piaget was a Swiss psychologist known for developing the theory of constructivism and studying cognitive development in children. He believed that intelligence develops through four stages that are related to age, where children progress from egocentrism to understanding other perspectives. Piaget investigated children's thinking and believed their cognitive processes developed through adapting to their environment. His work influenced approaches to education by emphasizing active, challenging learning activities suited to a child's developmental level.

8. First Piaget: investigated the hidden side of children’s minds. Piaget proposed that children moved from a position of egocentrism (thinking of one’s self) to sociocentrism (the tendency to believe that one's ethnic or cultural group is centrally important, and that all other groups are measured in relation to one's own).

9. Second Piaget: The first part, which is from the first stage, was the content of children's thinking. The second part was the process of intellectual activity. He believed this process of thinking could be regarded as an extension of the biological process of adaptation

11. Teachings 1. Children will provide different explanations of reality at different stages of cognitive development. 2. Cognitive development is facilitated by providing activities or situations that engage learners and require adaptation (i.e., assimilation and accommodation). 3. Learning materials and activities should involve the appropriate level of motor or mental operations for a child of given age; avoid asking students to perform tasks that are beyond their current cognitive capabilities. 4. Use teaching methods that actively involve students and present challenges.
