Each theory offers interpretations on the meaning of the children's development and behavior. Although the theories are clustered collectively into schools of thought, they differ within each school. Each theory identifies activities that are developmentally appropriate for young children. Froebel and Owen established the initial early childhood education programs, which occurred before the emergence of child development. However, Hilgard (1987) found that they had an implicit theory of child development. Young children construct implicit theories based on the information they obtained from their environment. At the end of the nineteenth century G. Stanley Hall and Bird T. Baldwin reported explicit theories of child development. Charles Darwin's theory of evolution profoundly affected these psychologists so that they established the maturationist theory of human development, although it had several limitations.
Center-based and home-based center childcare programs may offer different benefits to children and their families with regards to services and learning environment. However, the opportunities for children to learn and develop essential skills remain the same. Home-based childcare programs can leverage the inherent embedded curriculum opportunities inspired by the natural rhythms of life that occur throughout the day in a home such as preparing meals, household chores, and caretaking for younger children. 1e1e36bf2d
