From Wikipedia, the free encyclopedia
Jean Piaget was a Swiss philosopher, natural scientist and developmental psychologist, well known for his work studying children, his theory of cognitive development and its impact on constructivism-based pedagogy.
Piaget served as professor of psychology at the University of Geneva from 1929 to 1975 and is best known for reorganizing cognitive development theory into a series of stages, expanding on earlier work from James Mark Baldwin: four levels of development corresponding roughly to (1) infancy, (2) pre-school, (3) childhood, and (4) adolescence.
