Piaget's cognitive developmental theory approach stresses the growth of the ability to universalize or abstract as children grow. His theory deals only with children. It begins with the difference of the self from the environment (infancy), use of language to sort objects (2-7 years), the development of logical relations (7-11), and abstract propositional thinking (11 and up) (Salkind, 2004). The improvement here is that education can be structured for children that slowly take the mind away from objects (the younger stage) to abstract and logical ideas about objects (the later stage). If this is how kids learn, then this is how schools should be structured.

1) If research shows that "this is how kids learn," then how can we describe the various educational structures (i.e. homeschooling, Montessori, etc.) that also show promising results?

2) Is there a single method of educating people, especially those from different cultures and backgrounds? Why/why not?
