Conceptual analysis and considered arrangement of the elements contained in the ideas of continuity and interaction, understood as measures of the educational value of an experience, give rise to a theory about how to create educational energy. The goal is to create an equation that describes John Dewey's ideas about pedagogy. Following Dewey's ideas about criteria of experience and reorganizing them into a theory about creating educational energy requires serious philosophical work. Dewey's ideas connecting educational energy to qualities of experience describe a conversion of experience into education. Issac Newton's law works well for constructing a theory about creating educational energy for two reasons. First, it is the example Dewey turns to when providing a quintessential example of a natural law. Second, Newton's law is the standard example given of the sort of statement that must be made available to describe some educational process if some aspect of education, say, teaching, is to be understood as a science.
